Resistance Checks (4-Speed A/T)
Turn ignition off. Disconnect CC ECU harness connector. Using a Digital Volt/Ohmmeter (DVOM), make indicated resistance checks on harness side of disconnected CC ECU harness connector. SeeFigure and Fig 1 .DO NOT make any resistance checks directly on CC ECU as damage to ECU may result. If all circuits in this test are okay and all other circuit checks have been completed and system still does not function, replace CC ECU.
