Circuit/System Testing

Parking Assist Switch Circuit Malfunction

  1. Vehicle 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 1 and ground.
    • If 10 Ω or greater 
    1. Vehicle 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 
  3. Vehicle ON.
  4. Verify the scan tool Parking Assist Switch Status parameter is inactive.
    • If not Inactive 
    1. Vehicle OFF, disconnect the harness connector at the K41 Front and Rear Parking Assist Control Module.
    2. Test for infinite resistance between the control circuit terminal 5 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. Test for less than 1 V between the control circuit terminal 5 and ground.
    • If 1 V or greater 

      Repair the short to voltage on the circuit.

    • If less than 1 V 
  6. Connect a test lamp between the control circuit terminal 6 and the ground circuit terminal 1.
  7. Verify that a test lamp turns On and Off when Commanding the Parking Assist Switch On and Off with a scan tool.
    • If the test lamp is always OFF 
    1. Vehicle OFF, disconnect the harness connector at the K41 Front and Rear Parking Assist Control Module
    2. Test for infinite resistance between the control circuit and ground.
      • If less than infinite resistance, repair the short to ground in the circuit.
      • 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 K41 Front and Rear Parking Assist Control Module.
    • If the test lamp is always ON 
    1. Vehicle OFF, disconnect the harness connector at the K41 Front and Rear Parking Assist Control Module, vehicle in Service Mode.
    2. Test for less than 1 V between the control circuit and ground.
    • If 1 V or greater, repair the short to voltage on the circuit.
    • If less than 1 V, replace the K41 Front and Rear Parking Assist Control Module
    • If the test lamp turns ON and OFF 
  8. All OK.

Parking Assist Switch Indicator Circuit Malfunction

  1. Vehicle OFF, disconnect the harness connector at the S48E Multifunction Switch - Center Console, vehicle in Service Mode.
  2. Test for greater than 11 V between terminal 6 and ground.
    • If less than 11 V 

      Test the voltage circuit for a short to ground or an open/high resistance.

    • If greater than 11 V 
  3. Command the Park Assist Switch LED output control ON with the scan tool. Test for greater than 11 V between the control circuit terminal 6 and the ground circuit terminal 1.
    • If less than 11 V 

      Test the signal circuit for an open/high resistance.

    • If greater than 11 V 
  4. Command the Park Assist Switch Indicator Off with the scan tool.
  5. Test for less than 1 V between the terminal 6 and ground.
    • If 1 V or greater 

      Test the signal circuit for a short to voltage.

  6. If all circuits test normal, replace the S48E Multifunction Switch - Center Console.
