Circuit/System Testing

WARNING: This page is about a different car, the 2018 Cadillac XTS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Circuit/System Verification must be performed before Circuit/System Testing.

  1. Ignition OFF, disconnect the X2 harness connector at the A11 Radio.

    1. Ignition OFF, disconnect the X7 harness connector at the K9 Body Control Module and remove both E5 Backup Lamps.
    2. Test for infinite resistance between the control circuit terminal 2 and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • Go to next step: If infinite resistance
    3. Test for less than 2 Ω in the control circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K9 Body Control Module.
    • Go to next step: If the test lamp illuminates 
  4. Ignition OFF, disconnect the X7 harness connector at the K9 Body Control Module, ignition ON.
  5. Test for less than 1 V between the signal circuit terminal 2 and ground:
    • If 1 V or greater 

      Repair the short to voltage on the circuit.
