8. Disconnect PCM connector A (49P).
9. Disconnect SH-AWD control unit connector A (20P).
10. Check for continuity between PCM connector terminals A48, A49 and SH-AWD control unit connector terminals A10, A20 respectively.
Is there continuity?
YES -
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.?
NO -
Repair an open in the wires between the SH-AWD control unit and the PCM.?
