Circuit/System Testing

WARNING: This page is about a different car, the 2017 GMC Acadia. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF for 30 s, disconnect the harness connector at the appropriate B306 Parking Assist Sensor.
  2. Test for less than 15 Ω between the low reference circuit terminal 3 and ground.
    • If 15 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the K182 Parking Assist Control Module.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K182 Parking Assist Control Module.
    • If less than 15 Ω 
  3. Ignition ON, engine running.
  4. Test for 11.5-13.5 V between the 12 V reference circuit terminal 1 and ground.
    • If less than 11.5 V 
    1. Ignition OFF, disconnect the harness connector at the K182 Parking Assist Control Module.
    2. Test for infinite resistance between the 12 V 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 Ω in the 12 V reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K182 Parking Assist Control Module.
    • If greater than 13.5 V 
    1. Ignition OFF, disconnect the harness connector at the K182 Parking Assist Control Module, ignition ON.
    2. Test for less than 1 V between the 12 V reference circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K182 Parking Assist Control Module.
    • If between 11.5-13.5 V 
  5. Test for 4-12 V between the signal circuit terminal 2 and ground.
    • If less than 4 V 
    1. Ignition OFF, disconnect the harness connector at the K182 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 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 K182 Parking Assist Control Module.
    • If greater than 12 V 
    1. Ignition OFF, disconnect the harness connector at the K182 Parking Assist Control Module, ignition ON.
    2. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K182 Parking Assist Control Module
    • If between 4-12 V 
  6. Test or replace the appropriate B306 Parking Assist Sensor.
