If resistance is 5 ohms or greater, repair open in Violet/Light Green wire between CMTC and ambient temperature sensor. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  3. With jumper wires still connected, measure resistance at CMTC connector terminal No. 10 (Black/Light Blue wire). If resistance is less than 5 ohms, go to next step.
