DTC P1210: Traction Control System (TCS) Signal Circuit
- Check Input Signal Circuit - Turn ignition off. Disconnect TAC module harness connector. See Figure. Disconnect ECM harness connector. Using an ohmmeter, check continuity between TAC module harness connector terminal No. 7 (Red wire) and ECM harness connector terminal No. 31. If no continuity exists, repair fault in Red wire. If continuity exists, go to next step.
- Disconnect system harness connectors and inspect for damage or corrosion. Check ECM pins and terminals for damage or corrosion. Repair as necessary and retest. If fault is still present, check TAC module operation.
