The SH-AWD indicator does not go off, and no DTCs are stored
- Before you troubleshoot, review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).
- Make sure the No. 2 (SVTM-4) (30 A) fuse in the main under-hood fuse box is OK.
- Make sure there are no loose connector terminals at the SH-AWD control unit.
- Make sure the charging system and the battery are OK.
- Make sure the PGM-FI system and the A/T system is not in the middle of updating.
- Test the battery (see BATTERY TEST ). Charge or replace the battery if necessary.
- Turn the ignition switch to ON (II).
- Check the COMPLETE MEMORIZATION in the DATA LIST with the HDS.
Does the data list show COMPLETED?
YES -Go to step 4.
NO -Do the SH-AWD system memorization procedure for each of the following, then go to step 4.
- SH-AWD differential clutch torque (see SH-AWD® DIFFERENTIAL CLUTCH TORQUE MEMORIZATION )
- Yaw rate-lateral/longitudinal acceleration neutral position (see YAW RATE-LATERAL/LONGITUDINAL ACCELERATION NEUTRAL POSITION MEMORIZATION )
- SH-AWD control unit initialization (see SH-AWD® CONTROL UNIT INITIALIZATION )
- Check for DTCs in the VSA system with the HDS.
Are any steering angle sensor DTCs indicated?
YES -Go to the indicated DTC'S TROUBLESHOOTING .
NO -Go to step 5.
- Start the engine.
- Check the SH-AWD indicator value with the HDS.
Is the SH-AWD indicator value OFF?
YES -Go to the gauge control module self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ).
NO -Update the SH-AWD control unit if it does not have the latest software (see SH-AWD® CONTROL UNIT UPDATE ), or substitute a known-good SH-AWD control unit (see SH-AWD® CONTROL UNIT REPLACEMENT ), 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 SH-AWD® CONTROL UNIT REPLACEMENT ).
