DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	INSPECT FOR INSTRUMENT CLUSTER MALFUNCTION Switch the ignition to off. Using the M-MDS, perform the DTC inspection for the instrument cluster. (See DTC INSPECTION [INSTRUMENT CLUSTER] .) Are any DTCs detected?	Yes	Go to applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER] .)
1		No	Go to the next step.
2	INSPECT TCS OFF SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND Disconnect the TCS OFF switch. Disconnect the instrument cluster connector. Inspect for continuity between the TCS OFF switch connector terminal B (vehicle harness-side) and body ground. Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 5.
2		No	Go to the next step.
3	INSPECT TCS OFF SWITCH SIGNAL CIRCUIT FOR OPEN CIRCUIT Inspect for continuity between the TCS OFF switch connector terminal C (vehicle harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
3		No	Repair or replace the wiring harness, then go to Step 5.
4	INSPECT TCS OFF SWITCH Inspect the TCS OFF switch. (See TCS OFF SWITCH INSPECTION .) Is the TCS OFF switch normal?	Yes	Go to the next step.
4		No	Replace the TCS OFF switch, then go to the next step. (See TCS OFF SWITCH REMOVAL/INSTALLATION .)
5	VERIFY THAT THE SAME DTC IS NOT PRESENT Reconnect all disconnected connectors. Clear the DTCs from the memory. (See CLEARING DTC [DYNAMIC STABILITY CONTROL (DSC)] .) Are the same DTCs present?	Yes	Repeat the inspection from Step 1.
5		No	Go to the next step.
6	VERIFY THAT NO OTHER DTCS ARE PRESENT Are any other DTCs output?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [DYNAMIC STABILITY CONTROL (DSC)] .)
