Toyota RAV4 (XA40) 2013-2018 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.

Inspect tire
Check the tires for wear and proper inflation
pressure.
Standard cold tire inflation pressure:
220 kpa (2.2 Kgf/cm2, 32 psi)
Using a dial indicator, check the runout of the tires.
Standard tire runout:

Stuck in deceleration sensor
Description
The skid control ecu receives signals from the yaw rate and deceleration
sensor via the can
communication system.
The yaw rate sensor has a built-in deceleration sensor and detects the vehicle's
condition using 2 circuits
(gl1: g sensor 1, gl2: g sensor 2).
If there is t ...
Compressor circuit
Description
When the a/c switch is turned on, the magnetic clutch on signal is sent from
the air conditioning
amplifier. Then the mg clt relay turns on to operate the magnetic clutch.
