  1. Turn ignition off. Disconnect TCM harness connector. Turn ignition on. Measure voltage between ground and torque management request sense circuit at TCM harness connector. If voltage is 7-10 volts, replace TCM. If voltage is not as specified, go to next step.
  2. Turn ignition off. Measure resistance between ground and torque management request sense circuit at TCM harness connector. If resistance is less than 5 ohms, repair torque management request sense circuit for a short to ground. If resistance is not as specified, go to next step.
  3. Disconnect Powertrain Control Module (PCM) harness connector. Measure resistance of torque management request sense circuit between TCM and PCM harness connectors.
