Circuit/System Testing

  1. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the S48E Multifunction Switch - Center Console. It may take up to 2 minutes for all vehicle systems to power down.
  2. Test for less than 10 Ω between the ground circuit terminal 6 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF.
    2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the ground circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  3. Ignition ON.
  4. Verify the scan tool Advanced Parking Assist Switch parameter is Inactive.
    • If not Inactive 
    1. Ignition OFF, disconnect the harness connector at the K41 Front and Rear Parking Assist Control Module.
    2. Test for infinite resistance between the S48E Multifunction Switch - Center Console signal circuit terminal 7 and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the K41 Front and Rear Parking Assist Control Module.
    • If Inactive 
  5. Install a 3 A fused jumper wire between the signal circuit terminal 7 and ground.
  6. Verify the scan tool Advanced Parking Assist Switch parameter is Active.
    • If not Active 
    1. Ignition OFF, disconnect the harness connector at the K41 Front and Rear Parking Assist Control Module, ignition ON.
    2. Test for less than 1 V between the S48E Multifunction Switch - Center Console signal circuit terminal 7 and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V.
    3. Test for less than 2 Ω in the signal circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K41 Front and Rear Parking Assist Control Module.
    • If Active 
  7. Test or replace the S48E Multifunction Switch - Center Console.
