Circuit/System Testing

WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition Off and all vehicle systems Off. Disconnect the X175 harness connector at the T12 Automatic Transmission Assembly. It may take up to 2 min. for all vehicle systems to power down.
  2. Test for less than 10 Ω between the low reference circuit terminal 11 on the X175 harness connector and ground.
    • If 10 Ω or greater 
    1. Ignition Off, disconnect the harness connector at the K71 Transmission Control Module.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K71 Transmission Control Module.
    • If less than 10 Ω 
  3. Ignition On.
  4. Test for 4.8-5.2 V between the signal circuit terminal 12 and ground.
    • If not between 4.8-5.2 V 
    1. Ignition Off, disconnect the harness connector at the K71 Transmission Control Module.
    2. Test for infinite resistance between the signal circuit terminal 12 and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 1 Ω in the signal circuit end to end.
      • If 1 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 1 Ω, replace the K71 Transmission Control Module.
    • If between 4.8-5.2 V 
  5. Perform the Component Testing.
