Toyota RAV4 Service Manual: Auto lsd indicator light does not come on
Description
Refer to the description of "auto lsd indicator light remains on" (see page bc-164).
Wiring diagram
Refer to the auto lsd indicator light circuit (see page bc-165).
Inspection procedure
- Check can communication system
- Check if the can communication system dtc is output (see page ca-34).
Result 
- Read value of intelligent tester (auto lsd switch)
- Check the data list for proper functioning of the auto lsd switch.
Ok: on (downhill assist control switch is on) appears on the screen.
- Perform active test by intelligent tester (auto lsd indicator light)
- Select the active test, generate a control command, and then check that the auto lsd indicator light operates.
Ok: the auto lsd indicator light turns on and off.
- Inspect combination meter assembly
- Inspect the combination meter (see page me-15).
Replace abs and traction actuator assembly
- Inspect auto lsd switch
- Disconnect the auto lsd switch switch.
- Measure the resistance of the switch.
Standard resistance 
- Check wire harness (auto lsd switch - skid control ecu and body ground)
- Disconnect the a19 ecu connector.
- Disconnect the e51 switch connector.
- Measure the resistance of the wire harness side connectors.
