Diagnostic Procedure

  1. If DTC 56 occurs intermittently, see DIAGNOSTIC AIDS  . If DTC 56 is currently set, turn ignition switch to LOCK position. Disconnect motor pack 6-pin harness connector. Measure resistance across terminals No. 5 and 6 of motor pack. If resistance is below 2000 ohms, go to next step. If resistance is not below 2000 ohms, replace motor pack.
  2. Disconnect EBCM 8-pin harness connector. Measure resistance of Light Green wire between motor pack 6-pin harness connector terminal No. 6 and EBCM 8-pin harness connector terminal No. 2. If resistance is 2 ohms or less, go to next step. If resistance is not 2 ohms or less, repair open or high resistance in Light Green wire.
  3. Measure resistance of Light Green/Black wire between motor pack 6-pin harness connector terminal No. 5 and EBCM 8-pin harness connector terminal No. 1. If resistance is 2 ohms or less, go to next step. If resistance is not 2 ohms or less, repair open or high resistance in Light Green/Black wire.
  4. Check for poor contact or corrosion at EBCM and motor pack connectors. If terminals and connectors are okay, replace EBCM. After all diagnosis is complete, clear DTC and test drive vehicle for 3 drive cycles to verify that DTC does not reset. See CLEARING DIAGNOSTIC TROUBLE CODES  .
