Circuit/System Testing

NOTE: The torque transfer device solenoid valve is calibrated with and is part of the rear differential clutch control module. Both components must be replaced as a matched set.
  1. Ignition OFF, disconnect the X2 harness connector at the K47 Rear Differential Clutch Control Module.
  2. Test for infinite resistance between the differential clutch pump control circuit terminal A and ground.
  3. If less than the specified value, replace the M32 Differential Clutch Pump.
  4. Test for 1.5-20 Ω between the control circuit terminal A and the low reference circuit terminal B.
  5. If not within the specified range, replace the M32 Differential Clutch Pump.
  6. Replace the K47 Rear Differential Clutch Control Module.
