Toyota RAV4 Service Manual: Yaw rate 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.

1. Check can bus line for disconnection (yaw rate sensor branch wire)

1. Disconnect the k6 yaw rate sensor connector.
2. Measure the resistance of the wire harness side connector.

Standard resistance

2. Check wire harness (yaw rate sensor - battery and body ground)

1. Disconnect the k6 yaw rate sensor connector.
2. Measure the resistance of the wire harness side connector.

Standard resistance

3. Measure the voltage of the wire harness side connector.

Standard voltage
