•  Are any DTCs detected?
Yes
Go to applicable DTC inspection.
(See DTC TABLE [INSTRUMENT CLUSTER].)
No
Go to the next step.
2
INSPECT TCS OFF SWITCH (WITHOUT OFF-ROAD TRACTION ASSIST)/OFF-ROAD TRACTION ASSIST SWITCH (WITH OFF-ROAD TRACTION ASSIST) SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Switch the ignition off.
•  Disconnect the cluster switch connector.
•  Disconnect the instrument cluster connector.
•  Inspect for continuity between the cluster switch connector terminal D*1/B*2 (vehicle harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 5.
No
Go to the next step.
3
INSPECT TCS OFF SWITCH (WITHOUT OFF-ROAD TRACTION ASSIST)/OFF-ROAD TRACTION ASSIST SWITCH (WITH OFF-ROAD TRACTION ASSIST) SIGNAL CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between the cluster switch connector terminal E*1/C*2 (vehicle harness-side) and body ground.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 5.
4
INSPECT TCS OFF SWITCH (WITHOUT OFF-ROAD TRACTION ASSIST)/OFF-ROAD TRACTION ASSIST SWITCH (WITH OFF-ROAD TRACTION ASSIST)
•  Inspect the TCS OFF switch (without Off-Road Traction Assist)/Off-Road Traction Assist switch (with Off-Road Traction Assist).
•  Is the TCS OFF switch (without Off-Road Traction Assist)/Off-Road Traction Assist switch (with Off-Road Traction Assist) normal?
Yes
Go to the next step.
No
Replace the cluster switch, then go to the next step.
(See CLUSTER SWITCH REMOVAL/INSTALLATION.)
5
VERIFY THAT THE SAME DTC IS NOT PRESENT
•  Reconnect all disconnected connectors.
•  Clear the DTCs from the memory.
•  Using the M-MDS, perform the DSC HU/CM DTC inspection.
•  Is the same Pending DTC present?
Yes
Repeat the inspection from Step 1.
No
Go to the next step.
6
VERIFY THAT NO OTHER DTCS ARE PRESENT
•  Are any other DTCs output?
