Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | CHECK FOR DTCs IN ABS/TCS HU/CM • Have DTCs been recorded in memory? | Yes | Perform inspection using appropriate DTC.

*2 | CHECK FOR SHORT TO GROUND CIRCUITS IN ABS/TCS HU/CM • Disconnect ABS/TCS HU/CM. • Does TCS indicator light go out with ignition switch ON? | Yes | Replace ABS/TCS HU/CM (short to ground in ABS/TCS HU/CM).
No | Go to next step.
*3 | VERIFY WHETHER MALFUNCTION IS IN WIRING HARNESS (BETWEEN INSTRUMENT CLUSTER AND ABS/TCS HU/CM FOR SHORT TO GROUND) OR INSTRUMENT CLUSTER • Disconnect instrument cluster (20-pin). • Connect SST (adapter harness) (vehicle harness side only). • Is there continuity between SST (adapter harness) connector Terminal M and ground? | Yes | Repair wiring harness between ABS/TCS HU/CM (Terminal M) and instrument cluster.
No | Replace instrument cluster (short to ground in instrument cluster).
