TC and CG Terminal Circuit

1kzte Timing Control Valve

Connecting terminals TC and CG of the DLC3 causes the system to enter self-diagnostic mode. If a malfunction is present, DTCs will be output. When a particular warning light remains blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in the relevant ECU is suspected. CHECK WIRE HARNESS TC of DLC3 - ECM a Disconnect the A24 connector from the ECM. b Measure the resistance according to the value s in the table below. REPAIR OR REPLACE HARNESS OR CONNECTOR...

Compressor Lock Sensor Circuit

The ECM sends the engine speed signal to the TACO terminal of the A C amplifier. The A C amplifier reads the difference between compressor speed and engine speed. When the difference becomes too big, the A C amplifier determines that the compressor locks, and turns the magnetic clutch off. The ECM sends the engine speed signal to the TACO terminal of the A C amplifier. The A C amplifier reads the difference between compressor speed and engine speed. When the difference becomes too big, the A C...

How To Pull Dtc Toyota Avalon Air Conditioning

(1) Using SST, connect terminals TC and the CG of the DLC3. (2) Turn the ignition switch on (IG). (3) Read DTCs by the blinking pattern of the ABS warning light. HINT If the ABS warning light does not blink, inspect the TC terminal circuit or ABS warning light circuit. ABS warning light circuit (Remains on) ABS warning light circuit (Does not come on) As an example, the blinking patterns for a normal system code and trouble codes 11 and 21 are shown on the left. (4) Codes are explained in the...

a Leave the vehicle in a stationary condition and release the brake pedal for 1 second or more, and quickly depress the brake pedal with a force of 98 N 10 kgf, 22 lbf or more for 1 second or more. b Check that the ABS warning light stays ON for 3 seconds. Ensure that the ABS warning light comes on. While the ABS warning light stays on, continue to depress the brake pedal with a force of 98 N 10 kgf, 22 lbf or more. The ABS warning light comes on for 3 seconds every time the brake pedal...

Lost Communication with Steering Angle Sensor Module

This circuit detects the angle and direction of steering and automatically transmits its signal to the skid control ECU and distance control ECU. While the dynamic laser cruise control is either preparing for operation or operating, if the ECM continuously receives a steering sensor communication error signal for a certain amount of time, distance control ECU sends a signal to the ECM to record this trouble code. Cruise control ECU Distance control ECU This circuit uses CAN for communication....

Zero Point Calibration Of Yaw Rate Sensor Toyota Avalon

The ABS amp TRACTION actuator assembly receives signals from the yaw rate sensor acceleration sensor via CAN communication system. The yaw rate sensor has the built-in acceleration sensor. If there is trouble in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, the DTCs U0123 62 lost communication with the yaw rate sensor module and U0124 95 lost communication with the lateral acceleration sensor module are output. The DTCs are also output when the...

To confirm DTC B perform the following steps aWith engine ON enter the DTC check mode

b Press the R F Recirculation Fresh switch to enter actuator check mode, and set the operation to Step No.3. c Press the AUTO switch to return to DTC check mode. d The DTC is displayed after approx. 3 sec. 5 Even though the system is in good condition, DTC is output when the seat sensor temperature senses -40 C -40 F and over 99 C 210.2 F . 6 The A C amplifier memorizes the DTC of the respective malfunction that has occurred for a period of the time indicated in the brackets.
