Toyota RAV4 Service Manual: Steering angle sensor communication stop mode
Description
Wiring diagram
Inspection procedure
Notice:
- Turn the ignition switch off before measuring the resistances of the main wire and the branch wire.
- After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.
- Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition switch, any switches or doors. If doors need to be opened in order to check connectors, open the doors and leave them open.
Hint:
Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.
- Check can bus line for disconnection (steering angle sensor branch wire)
- Disconnect the e11 steering angle sensor connector.
- Measure the resistance of the wire harness side connector.
Standard resistance 
- Check wire harness (steering angle sensor - battery and body ground)
- Disconnect the e11 steering angle sensor connector.
- Measure the resistance of the wire harness side connector.
Standard resistance
- Measure the voltage of the wire harness side connector.

Air inlet damper control servo motor circuit
Description
The damper servo (air inlet control) sends pulse signals to indicate the
damper position to the air
conditioning amplifier. The air conditioning amplifier activates the motor
(normal or reverse) based on
these signals to move the air inlet control damper to the appropriate pos ...
