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.
- Ignition OFF, disconnect the X2 harness connector at the K47 Rear Differential Clutch Control Module.
- Test for infinite resistance between the differential clutch pump control circuit terminal A and ground.
- If less than the specified value, replace the M32 Differential Clutch Pump.
- Test for 1.5-20 Ω between the control circuit terminal A and the low reference circuit terminal B.
- If not within the specified range, replace the M32 Differential Clutch Pump.
- Replace the K47 Rear Differential Clutch Control Module.
