I CAN 1. General

The '07 Camry uses two types of CAN that have different communication speeds: HS-CAN (500 kbps) and MS-CAN (250 kbps).

The HS-CAN consists of the CAN No.1 bus. The terminating resistors of the CAN No.1 bus are built into the ECM and meter ECU.

The MS-CAN consists of the MS bus. The terminating resistors of the MS-bus are built into the main body ECU and certification ECU. The MS bus is used only when the smart key system (certification ECU), which is optional equipment, is provided.

The main body ECU, which has a gateway function, is used to transmit data between the CAN No.1 bus and the MS bus.

3. Diagnosis

If a malfunction occurs on the CAN communication line, the ECU that is connected to the CAN communication line stores the DTC (Diagnostic Trouble Code) in its memory.

The 5-digit DTC can be read by connecting a hand-held tester to the DLC3.

The DLC3 is equipped with CAN-H and CAN-L terminals for CAN diagnosis. It is possible to determine if there is an open or short in the main wire of the CAN No. 1 bus by measuring the resistance value between these terminals.

For details, see the 2007 Camry Repair Manual (Pub. No. RM0250U).

Service Tip->.

The diagnostic communication uses the CAN protocol. Therefore, a hand-held tester and a dedicated adapter [CAN VIM (Vehicle Interface Module)] are required for accessing diagnostic data. For details, see the 2007 Camry Repair Manual (Pub. No. RM0250U).

The AVC-LAN is used to transmit data only between the audio head unit and the stereo amplifier on models with the JBL premium sound system.

3. Diagnosis

If a malfunction occurs in the AVC-LAN communication line, the audio head unit stores a DTC (Diagnostic Trouble Code) in its memory.

The DTC of models with the navigation with AV system can be read on the diagnosis menu display on the audio head unit.

The DTC of models without the navigation with AV system can be read on the LCD of the audio head unit. For details, see the 2007 Camry Repair Manual (Pub. No. RM0250U).

- DAYTIME RUNNING LIGHT SYSTEM

A daytime running light system is designed to automatically illuminate the headlights (dimmed Hi beam), during the daytime to keep the car highly visible to other vehicles.

The main body ECU and power distributor control this system. The main body ECU transmits a turn ON signal to the power distributor, and the power distributor illuminates and dims the Hi beam with the duty control.

This system is enabled when the conditions given below are met:

- Engine Speed Signal Input (Engine Running Condition)

- Light Control Switch OFF*2, TAIL, or AUTO position (if headlight-on control is not being performed by the automatic light control.)

- Parking Brake Switch: OFF

*1: The power source condition can be changed by operating the engine switch on models with the smart key system, and the ignition switch on models without the smart key system. *2: Only for Canadian package models

Condition

Item

Condition (1)

With power source*2 OFF and all doors closed, any door is unlocked. With all doors closed, power source*2 is changed from ACC to OFF. With power source OFF and all doors closed, key enters any actuation area around the doors. (Only for models with smart key system)

Condition (2)

Any door is open.

Condition (3)

With power source*2 OFF, all doors are closed.

Condition (4)

Power source*2 is ACC or ON.

More than 15 seconds have elapsed since the Light ON State (15 second duration)*1.

With power source*2 OFF and all doors closed, all doors are locked.

Condition (5)

With power source*2 ACC or ON, all doors are closed.

With power source*2 OFF and all doors closed, all doors are locked.

*1: The function setting can be changed using the customized body electronics system. For details, refer to

Customized Body Electronics System section on page BE-13. *2: The power source condition can be changed by operating the engine switch on models with the smart key system, and the ignition switch on models without the smart key system.

4. Battery Saving Control

When the following two conditions have been met, battery saving control turns off the lights illuminated by the illuminated entry controls. Battery saving control is controlled by the main body ECU.

The key is not in the actuation area (models with smart key system), or the ignition key is not in the ignition key cylinder (models without smart key system).

There is no change in the condition of the doors for 20 minutes.

■ AUTOMATIC LIGHT CONTROL SYSTEM

When the light control switch is in the AUTO position, the automatic light control system detects ambient light levels and controls the headlights and taillights (parking lights, taillights and license plate lights).

The light control sensor detects the ambient light levels. This sensor is integrated into the solar sensor that is used for automatic air conditioning control on models with automatic air conditioning.

The main body ECU controls this system. ^ System Diagram ^

■ LIGHT TURN-OFF SYSTEM

The light turn-off system is used to prevent the driver from leaving the vehicle with the exterior lights (headlights, fog lights, parking lights, taillights and license plate lights) ON.

If the pwer source* is turned OFF and any door is opened and all doors (including the luggage compartment door) are closed with all exterior lights ON, this system turns them OFF approximately 30 seconds after door closure. However, with all the doors locked, when the lock button on the wireless remote control is pushed, the exterior lights are turned OFF immediately.

When the power source* is turned OFF and the driver's door is opened with the exterior lights except headlights ON, this system turns them OFF.

*: The power source condition can be changed by operating the engine switch on models with the smart key system, and the ignition switch on models without the smart key system.

METER

- COMBINATION METER 1. General

An optitron display type combination meter is used on XLE and LE grade models. The optitron display type meter realizes excellent visibility through the use of smoke acrylic in the protective panel, and bright LEDs (Light Emitting Diodes) that have high contrast to illuminate the indicator and the dial.

A multi-information display is provided on the speedometer on XLE grade models.

A meter ECU and buzzer are enclosed in the combination meter. This ECU maintains communication with other ECUs through the CAN (Controller Area Network).

Illumination control, which turns on the combination meter illumination at different time intervals when the power source* is switched to IG-ON, has been provided.

A step-motor type movement is used to actuate the indicators of the speedometer, the fuel gauge, the engine coolant temperature gauge and the tachometer.

*: The power source condition can be changed by operating the engine switch on models with the smart key system, and the ignition switch on models without the smart key system.

3. Illumination Control

When the power source is switched to IG-ON, the illumination control operates as follows (1, 2). However, all illuminations turn off while the engine is cranked.

When the power source is switched to OFF, the illumination control is as follows (3).

1) The needles of the speedometer, tachometer, fuel gauge and engine coolant temperature gauge are illuminated and "Camry" appears on the multi-information display.
