TCM Power & Ground Circuit

WARNING: This page is about a different car, the 1996 Suzuki Esteem. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Disconnect TCM harness connectors. Check for poor terminal contact. Repair as necessary. If connections are okay, turn ignition on. Using a DVOM, measure voltage between ground and TCM harness connector E26, terminal No. 25 (Black/White wire). If reading is 10-14 volts, go to next step. If reading is not as specified, repair open in Black/White wire.
  2. Turn ignition off. Using A DVOM, check for continuity between ground and TCM harness connector E26, terminal No. 2 (Black/Red wire). If continuity is present, power and ground circuits are okay at this time. If continuity is not present, repair open in Black or Black/White wire between TCM and chassis ground. Retest system.
