Circuit/System Testing

  1. Ignition OFF for 1 min, scan tool must be disconnected for steps 1 and 2 to allow module to power down. Disconnect the harness connector at the affected rear object sensor.
  2. Test for less than 10 ohms between the low reference circuit terminal 2 and ground.
    • If 10 ohms or greater 
    1. Ignition OFF, disconnect the harness connector X2 at the K41R Rear Parking Assist Control Module.
    2. Test for less than 2 ohms in the low reference circuit end to end.
      • If 2 ohms or greater, repair the open/high resistance in the circuit.
      • If less than 2 ohms replace the K41R Rear Parking Assist Control Module.
    • If less than 10 ohms 
  3. Ignition ON.
  4. Test for 7.5-9.5V between the 8V reference circuit terminal 1 and ground.
    • If less than 7.5V 
    1. Ignition OFF, disconnect the harness connector at the K41R Rear Parking Assist Control Module.
    2. Test for infinite resistance between the 8V reference circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 ohms in the 8V reference circuit end to end.
      • If 2 ohms or greater, repair the open/high resistance in the circuit.
      • If less than 2 ohms, replace the K41R Rear Parking Assist Control Module.
    • If greater than 9.5V 
    1. Ignition OFF, disconnect the harness connector at the K41R Rear Parking Assist Control Module, ignition ON.
    2. Test for less than 1V between the 8V reference circuit and ground.
      • If 1V or greater, repair the short to voltage on the circuit.
      • If less than 1V, replace the K41R Rear Parking Assist Control Module.
    • If between 7.5-9.5V 
  5. Ignition ON.
  6. Test for 4.8-5.2V between the signal circuit terminal 3 and ground.
    • If less than 4.8V 
    1. Ignition OFF, disconnect the harness connector at the K41R Rear Parking Assist Control Module.
    2. Test for infinite resistance between the signal circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 ohms in the signal circuit end to end.
      • If 2 ohms or greater, repair the open/high resistance in the circuit.
      • If less than 2 ohms, replace the K41R Rear Parking Assist Control Module.
    • If greater than 5.2V 
    1. Ignition OFF, disconnect the harness connector at the K41R Rear Parking Assist Control Module, ignition ON.
    2. Test for less than 1V between the signal circuit and ground.
      • If 1V or greater, repair the short to voltage on the circuit.
      • If less than 1V, replace the K41R Rear Parking Assist Control Module.
    • If between 4.8-5.2V 
  7. Test or replace the affected Rear Object Sensor.
