Does the SH-AWD indicator come on?

YES - Update the SH-AWD control unit if it does not have the latest software, or substitute a known-good SH-AWD control unit 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.

NO - Go to the gauge control system troubleshooting.
