YES -
Go to step 7.
NO -
Replace the SH-AWD relay See: Powertrain Management/Transmission Control Systems/Relays and Modules - Transmission and
Drivetrain/Relays and Modules - Differential/Actuator Relay/Service and Repair.?
7. Disconnect SH-AWD control unit connector A (20P).
8. Turn the ignition switch to ON (II).
9. Measure the voltage between SH-AWD control unit connector terminal A17 and body ground with the SH-AWD relay removed.
Is there battery voltage?
YES -
Repair a short to power in the wire between the SH-AWD control unit and the SH-AWD relay (FSR line).?
NO -
Go to step 10.
10. Turn the ignition switch to LOCK (0).
11. Disconnect SH-AWD control unit connector B (8P).
12. Measure the voltage between SH-AWD control unit connector terminals B1 and B2.
Is there battery voltage?
YES -
Repair a short to power in the wire between the SH-AWD control unit and the SH-AWD relay (PWR line).?
NO -
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.?
