Circuit/System Testing

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the Q49 Rear Differential Clutch Solenoid Valve, ignition ON.
  2. Test for 3-5 V between the control circuit terminal B and ground.
    • If less than 3 V 
    1. Ignition OFF, disconnect the harness connector at the K47 Rear Differential Clutch Control Module.
    2. Test for infinite resistance between the control 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 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 K47 Rear Differential Clutch Control Module.
    • If greater than 5 V 
    1. Ignition OFF, disconnect the harness connector at the K47 Rear Differential Clutch Control Module, ignition ON.
    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 K47 Rear Differential Clutch Control Module.
    • If between 3-5 V 
  3. Test for less than 1 V between the control circuit terminal A and ground.
    • If 1 V of greater 
    1. Ignition OFF, disconnect the X2 harness connector at the K47 Rear Differential Clutch Control Module.
    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 the 1 V, replace the K47 Rear Differential Clutch Control Module.
    • If less than 1 V 
  4. Ignition OFF, connect the harness connector at the Q49 Rear Differential Clutch Solenoid Valve. Disconnect the X2 harness connector at the K47 Rear Differential Clutch Control Module.
  5. Test for infinite resistance between the control circuit terminal A and ground.
    • If less than infinite resistance 
    1. Ignition OFF, disconnect the harness connector at the Q49 Rear Differential Clutch Solenoid Valve.
    2. Test for infinite resistance between the control circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the Q49 Rear Differential Clutch Solenoid Valve.
    • If infinite resistance 
  6. Test for 1.5-2.5 Ω between the control circuit terminal A and the control circuit terminal B.
  7. Test for infinite resistance between the control circuit and ground.
    • If not between 1.5-2.5 Ω 
    1. Ignition OFF, disconnect the harness connector at the Q49 Rear Differential Clutch Solenoid Valve.
    2. Test for less than 2 Ω between the K47 Rear Differential Clutch Control Module control circuit terminal A and the Q49 Rear Differential Clutch Solenoid Valve control circuit terminal A.
      • If 2 Ω or greater, repair the open/high resistance on the circuit.
      • If less than 2 Ω, test or replace the Q49 Rear Differential Clutch Solenoid Valve.
    • If between 1.5-2.5 Ω 
  8. Replace the K47 Rear Differential Clutch Control Module.
