DTC 16: Traction Control System (TCS) Signal

  1. Check Input Signal Circuit  - Turn ignition off. Disconnect ECM harness connector and Traction Control Module (TCM) 20-pin harness connector. Check harness continuity between ECM terminal No. 36 and TCM terminal No. 7 (Red/Green wire). See Fig 1 and Fig 2 . If continuity is present, go to next step. If continuity is not present, verify harness and connector continuity between ECM and TCM. Repair harness or connectors as necessary.
  2. Check Component  - Inspect TCS function. See TRACTION CONTROL SYSTEM article in the BRAKES section. Replace TCS component(s) if necessary and perform FINAL CHECK.
