  1. Ignition ON.
  2. Verify the scan tool Parking Assist Switch parameter is Inactive.
    • If Active 
    1. Ignition OFF, disconnect the harness connector at the K41R Rear Parking Assist Control Module.
    2. Test for infinite resistance between the signal circuit terminal 8 and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the K41R Rear Parking Assist Control Module.
    • If Inactive 
  3. Ignition OFF, disconnect the harness connector at the S48A Multifunction Switch - Instrument Panel.
  4. Test for less than 10 Ω between the ground circuit terminal 2 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 circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  5. Install a 3 A fused jumper wire between the signal circuit terminal 5 and ground.
    NOTE: If jumper is in place for more than 10 s, DTC B0967 02 will set.
  6. Verify the scan tool Parking Assist Switch parameter is Active.
    • If Inactive 
    1. Ignition OFF, disconnect the harness connector at the K41R Rear Parking Assist Control Module, ignition ON.
    2. Test for less than 1 V between the signal circuit terminal 8 and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V
    3. Ignition OFF
    4. 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 K41R Rear Parking Assist Control Module.
    • If Active 
  7. Test or replace the S48A Multifunction Switch - Instrument Panel.
