How to Check for Diagnostic Trouble Codes (DTCs)

WARNING: This page is about a different variant/trim than selected.

When the real time AWD control unit senses an abnormality in the input or output systems, the AWD system indicator in the gauge control module will usually come on, the MIL, the D indicator, the VSA indicator, and/or the ABS indicator may also come on.

NOTE: Make sure the 12 volt battery is in good condition and fully charged.

1. Turn the vehicle to the OFF (LOCK) mode, then connect the HDS to the DLC .

2. Turn the vehicle to the ON mode. Make sure the HDS communicates with the vehicle and the real time AWD control unit. If it does not communicate, go to the real time AWD system symptom troubleshooting for HDS does not communicate . Follow the prompts on the HDS to display the DTC(s) on the screen. Check the DTC and the freeze data for all systems. After determining the DTC(s), refer to the DTC Troubleshooting.

NOTE: See the HDS help menu for specific instructions.

3. If there are PGM-FI system DTCs and other system DTCs at the same time, troubleshoot the PGM-FI system DTCs first, otherwise the real time AWD DTC may return.

4. After recording the DTCs, clear all DTCs.

5. Test-drive the vehicle for several minutes in 4WD mode, and check for DTCs. If the DTC returns, refer to the DTC Troubleshooting. If the DTC does not return, there was an intermittent problem within the circuit. Make sure all connectors and terminals in the circuit are tight.
