Is there continuity?
YES -
Repair a short in the wire between SH-AWD control unit connector terminal A3 and body ground.?
NO -
Check for loose connector terminals at the SH-AWD control unit and repair if necessary. If the connections are OK, update the SH-AWD control
unit if it does not have the latest software See: Powertrain Management/Transmission Control Systems/Relays and Modules - Transmission and
Drivetrain/Relays and Modules - Differential/Control Unit/Testing and Inspection/SH-AWD Control Unit Update, or substitute a known-good
SH-AWD control unit See: Powertrain Management/Transmission Control Systems/Relays and Modules - Transmission and Drivetrain/Relays and
Modules - Differential/Control Unit/Service and Repair, and recheck. If the symptom/indication goes away with the updated SH-AWD control
unit, troubleshooting is complete. If the symptom/indication goes away with a known-good SH-AWD control unit, replace the original SH-AWD
control unit See: Powertrain Management/Transmission Control Systems/Relays and Modules - Transmission and Drivetrain/Relays and Modules -
Differential/Control Unit/Service and Repair.?
NOTE: If a new SH-AWD control unit was used in place of the known-good control unit and the new control unit will not initialize, replace the
rear differential right side case.
7. Disconnect the right solenoid 4P connector.
8. Connect SH-AWD control unit connector terminals A3 and A12 with a jumper wire. Disconnect the right solenoid 4P connector, then check
for continuity between right solenoid 4P connector terminals No. 3 and No. 4.
Is there continuity?
YES -
Replace the rear differential right side case See: Transmission and Drivetrain/Differential Assembly/Service and Repair/Overhaul/Rear Differential
Side Case Replacement.?
NO -
Repair an open in the wires between right solenoid 4P connector terminals No. 3 and No. 4.?
9. Disconnect the right solenoid 4P connector.
10. Check for continuity between right solenoid 4P connector terminals No. 3 and No. 4.
