NOTE: Before you troubleshoot, review the general troubleshooting information See: Transmission and Drivetrain/Differential Assembly/Testing
and Inspection/Initial Inspection and Diagnostic Overview.
1. Turn the ignition switch to LOCK (0).
2. Disconnect SH-AWD control unit connector A (20P).
3. Check for continuity between SH-AWD control unit connector terminals A3 and A12.
Is there continuity?
YES -
Go to step 4.
NO -
Go to step 7.
4. Check the REAR DIFFERENTIAL FLUID TEMPERATURE in the DATA LIST is above 68 掳F (20 掳C) with the HDS before proceeding
to the next step. If the temperature is below 68 掳F (20 掳C), drive the vehicle to warm up the rear differential until the fluid temperature
becomes above 68 掳F (20 掳C).
5. Measure the resistance between SH-AWD control unit connector terminals A3 and A12.
Is there 2.0 Ohms or more?
YES -
Go to step 6.
NO -
Go to step 9.
6. Check for continuity between SH-AWD control unit connector terminal A3 and body ground.
