Recondition Battery Guide

This Do It Yourself Recondition Battery Guide consists of 21 chapters that will show you step-by-step how to recondition your battery. When a healthy battery is recharged, this lead sulfate is converted back to lead and sulfuric acid. But in tired battery, the lead sulfate changes to a crystalline form that coats the batterys lead plates reducing its capacity. This process is known as sulfation. It is a common occurrence in lead-acid batteries and a major reason for their failure. The good news is that you can often reverse sulfation utilizing a specialized high-current, pulse that effectively breaks down the crystalline lead sulfate and turns it back into lead and sulfuric acid, thus cleaning the lead plates and restoring charge capacity. So before you throw that battery away, consider battery reconditioning as a way to save it. Read more here...

Step Battery Voltage Correction

The final step is a battery voltage correction. The input signal used in battery voltage corrections is 0 Battery Voltage (+B) There is an operational delay between the time the ECU sends the injection signal to the driver circuit and the actual opening of the injector. This delay changes with the strength of the magnetic field around the injector coil. The delay increases as battery voltage falls. To determine final injection duration, the ECU corrects for injector opening delay by using a battery voltage correction coefficient. The battery voltage correction coefficient increases injection duration as sensed battery voltage falls.

Input Signal Check Using handheld tester

The cancel condition is that battery voltage is supplied to terminal STP. When the brake is on, battery voltage is normally applied through the STOP fuse and stop light switch to terminal STP of the hybrid vehicle control ECU, and the hybrid vehicle control ECU turns the cruise control OFF. If the harness connected to terminal STP has an open circuit, terminal STP will have battery voltage and the cruise control will be turned OFF.

Battery Current Sensor

Rav4 Battery Current Sensor

Installed on the negative terminal of the battery, this sensor detects the amount of charging and discharging amperage of the battery and sends signal to the ECM. Based on this signal, the ECM calculates the battery capacity. A Hall IC is used for detecting the amount of charging and discharging amperage. The changes that occur in the magnetic flux density in the core as a result of the charging and amperage of the battery are converted and output as voltage.

Inspection Procedure

Toyota A340 Speed Sensor

Read freeze frame data using a TOYOTA hand-held tester or OBD II scan tool. Because freeze frame data records the battery condition when the malfunction is detected. When troubleshooting, this is useful for knowing the battery condition. Check and replace Battery ECU (See page IN-41).

Starting Injection Control

To provide accurate fuel injection duration during cranking periods, the ECU uses a program which determines a basic injection volume based on engine coolant temperature. Once a basic injection duration is calculated, corrections are made for intake air temperature and battery voltage (which is typically low under cranking load). Injection duration while cranking is corrected for battery voltage by increasing injection duration at lower voltage.

Air Flow Sensor Terminal Identification First Design Sensor

Www Toyota Carina Airflow Sensor

Battery voltage supply to sensor The air flow meter and ECU are wired as shown in the diagram. Signal characteristics are depicted by the accompanying graph. The use of battery voltage, VB, as a sensor input necessitates the use of the Vc terminal as a constant reference signal for the ECU. This is because battery voltage may change with variances in electrical load and ambient temperatures. Without the use of a constant reference voltage, these changes would cause a change in the Vs signal value recognized by the ECU.

Tire Pressure Warning System Valve Transmitter

If the battery voltage drops, the tire pressure warning system valve & transmitter assembly must be replaced. Furthermore, if the battery voltage drops, the tire pressure warning system valve & transmitter will be unable to transmit signals, which causes a DTC to be output.

Electrical Diagnostic Testing Onboard Diagnostics

Once a malfunction is stored in the memory system, it will be retained until canceled (erased). The vehicle battery constantly supplies 12 volts to the ECU B terminal to maintain memory even if the ignition switch is turned off. If the malfunction is repaired or returns to normal operation, the warning light will go off but the malfunction code will remain in memory. In order to erase a diagnostic code from the memory, a specified fuse must be removed for approximately 30 seconds with the ignition switch is off. The fuse is identified in the repair manual or on the ECT Diagnostic Information technician reference card.

Precautions For Vehicles With An Audio System With Builtin Antitheft System

The Audio System with acoustic flavor only for U.S.A. specification vehicles shown on the left has a built-in anti-theft system which makes the audio system sound-less if stolen. If the power source for the audio system is cut even once, the anti-theft system operates so that even if the power source is reconnected, the audio system will not produce any sound unless the ID number selected by the customer is input again. Accordingly, when performing repairs on vehicles equipped with this system, before disconnecting the battery terminals or removing the audio system the customer should be asked for the ID number so that the technician can input the ID number afterwards, or else a request made to the customer to input the ID number.

Electrical Load Sensor ELS

The ELS signal at the ECU will be low as long as the tail lamps and rear window defogger are off. When either of these accessories are turned on, current flows to the accessory and through an isolation diode to the ECU. When either accessory is on, the signal at the ECU will go to battery voltage.

Pattern A Off A Igon after the engine is started

The ECM and main body ECU both output the starter relay signal in order to actuate the starter. Both the ECM and main body ECU output the signal in order to prevent situations where the starter may fail to operate, such as when the battery voltage supplied to the ECM is low.

Power Side Switch Circuit

A power side switch is a switch located between the power supply and load. Sometimes the power side switch is called hot side switch because it is located on the hot side, that is, before the load, in a circuit. The Stop Lamp switch is a good example. When the brake pedal is depressed, the Stop Lamp switch closes sending battery voltage to the ECM. This signals the ECM that the vehicle is braking. The following switches act as switches for the ECM. Usually, they are supply side switches. Note in the figure(s) their location between the battery and ECM. Many switches that commonly use battery voltage as the source are

Description Operation

When ignition is turned on, battery voltage flows from generator terminal L through IC regulator to ground, causing discharge warning light to come on. When engine starts, generator RPM increases, which increases generator output voltage. When generator output voltage is greater than battery voltage, voltage to recharge battery flows from terminal B. At the same time, voltage at terminal L increases and the potential difference between battery and terminal L ceases, causing discharge warning light to go off.

Ammetersanalog And Digital

Ammeters measure amperage, or current flow, in a circuit, and provide information on current draw as well as circuit continuity. High current flow indicates a short circuit, unintentional ground or a defective component. Some type of defect has lowered the circuit resistance. Low current flow may indicate high resistance or a poor connection in the circuit or a discharged battery. No current indicates an open circuit or loss of power.

Monitor Description

The battery supplies electricity to the ECM even when the ignition switch is in the OFF position. This power allows the ECM to store data such as DTC history, freeze frame data and fuel trim values. If the battery voltage falls below a minimum level, these memories are cleared and the ECM determines that there is a malfunction in the power supply circuit. When the engine is next started, the ECM illuminates the MIL and sets the DTC.

Circuit Description

When the engine is cranked, the intake air flow is slow, so fuel vaporization is poor. A rich mixture is therefore necessary in order to achieve good startability. While the engine is being cranked, the battery voltage is applied to terminal STA of the ECM. The starter signal is mainly used to increase the fuel injection volume for the starting injection control and after-start injection control.

Solenoid

Stateofcharge Test

The hydrometer compares the exact weight of electrolyte with that of water. Strong electrolyte in a charged battery is heavier than weak electrolyte in a discharged battery. TEST RESULTS Specific gravity readings tell a lot about battery condition. 2. Turn headlamps off and connect the voltmeter across the battery terminals. 3. Read the voltmeter. A fully charged battery will have an open-circuit voltage of at least 12.6 volts. A dead battery will have an open-circuit voltage of less than 12.0 volts.

Ground Point

The Current Flow Chart section, describes which parts each power source (fuses, fusible links, and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.

Component Tests

Toyota Echo Battery

Apply positive battery voltage to actuator terminal No. 2 and negative battery voltage to actuator terminal No. 6. See Fig. 5 . Listen for actuator engagement operation. Using an ohmmeter, check for continuity between actuator terminal Nos. 3 and 4. If there is no continuity, replace actuator. 3. Apply positive battery voltage to actuator terminal No. 6 and negative battery voltage to actuator terminal No. 2. Listen for actuator disengagement operation. Using an ohmmeter, check that there is no continuity between actuator terminals No. 3 and 4. If there is continuity, replace actuator.

And recheck

Apply positive battery voltage to terminal No. 7 and negative voltage to terminal No. 5. Ensure continuity exists between terminal Nos. 1 and 3, and no continuity exists between terminal Nos. 1 and 2. 3. Apply positive battery voltage to terminal No. 7 and negative voltage to terminal No. 2. Ensure no continuity exists between terminal Nos. 9 and 10. 4. Apply positive battery voltage to terminal No. 9 and negative voltage to terminal No. 10. Ensure continuity exists between terminal Nos. 3 and 4 and no continuity exists between terminal Nos. 2 and 4. If continuity is not as specified, replace relay.

Charging

All battery chargers operate on the same principle an electric current is applied to the battery to reverse the chemical action in the cells. Never connect or disconnect leads with the charger turned ON. Follow the battery charger manufacturer's instructions. And, do not attempt to charge a battery with frozen electrolyte. When using a battery charger, always disconnect the battery ground cable first. This will minimize the possibility of damage to the alternator or to electronic components. Otherwise, use a charger with polarity protection that prevents reverse charging. Fast charging is used to charge the battery for a short period of time with a high rate of current. Fast charging may shorten battery life. If time allows, slow charging is preferred. Some low maintenance batteries cannot be fast charged. Set the voltage switch to the correct battery voltage. Disconnect the charger cables from the battery terminals. 1. The maximum charging current should be less than 1 1 10th of the...

Visual Inspection

Tightening The Belts Mazda Protege

Battery service should begin with a thorough visual inspection. This may reveal simple, easily corrected problems, or problems that might require battery replacement. 6. Check for cloudy or discolored electrolyte caused by overcharging or vibration. This could cause high self discharge. The problem should be corrected and the battery replaced.

Alternator Terminals

When the ignition switch is on, battery current is supplied to the regulator through a wire connected between the switch and terminal IG. When the alternator is charging, the charging current flows through a large wire connected between terminal B and the battery. At the same time, battery voltage is monitored for the MIC regulator through terminal S. The regulator will increase or decrease rotor field strength as needed. The indicator lamp circuit is connected through terminal U'. If there is no output, the lamp will be lit. The rotor field coil is connected to terminal P, which is accessible for testing purposes through a hole in the alternator end frame.

Basic Repair Hint

(4) Clean the battery terminals and cable ends with a clean shop rag. Do not scrape them with a file or other abrasive objects. (5) Install the cable ends to the battery terminals with the nut loose, and tighten the nut after installation. Do not use a hammer to tap the cable ends onto the terminals.

Solenoids

Like stepper motors, solenoids are digital actuators. One terminal is attached to battery voltage while the other is attached to the computer which opens and closes the ground circuit as needed. When energized, the solenoid may extend a plunger or armature to control functions such as vacuum flow to various emission-related systems or fuel injection. Most actuators are solenoids.

Selftest Answers

B - In a fully discharged battery, both plates are covered with lead sulfate and the electrolyte is diluted to mostly water. (Page 9. C - In a battery capacity or heavy-load test, if the voltmeter reading falls below 9.6 volts, the battery is either discharged or defective. (Page 13.)

Operation

When the engine is running, battery power energizes the charging system and engine power drives it. The charging system then generates electricity for the vehicle's electrical systems. At low speeds with some electrical loads on (e.g., lights and window defogger), some battery current may still be needed. But, at high speeds, the charging system supplies all the current needed by the vehicle. Once those needs are taken care of, the charging system then sends current into the battery to restore its charge.

Construction

(regardless of the number or size of plates). Battery cells are connected in series, so the number of cells determines the battery voltage. A 1 2 - volt battery has six cells. A lead-acid storage battery can be partially discharged and recharged many times. There are four stages in this discharging charging cycle. 3. DISCHARGED In a fully discharged battery, both plates are covered with lead sulfate (PbSO4) and the electrolyte is diluted to mostly water (H2O).

Battery Types

SECONDARY CELLS The metals and acid mixture change as the battery supplies voltage. The metals become similar, the acid strength weakens. This is called discharging. By applying current to the battery in the opposite direction, the battery materials can be restored. This is called charging. Automotive lead-acid batteries are secondary cells. 3. WET-CHARGED The lead-acid battery is filled with electrolyte and charged when it is built. During storage, a slow chemical reaction will cause self-discharge. Periodic charging is required. For Toyota batteries, this is every 5 to 7 months.
