DTC P186D-97: Clutch Actuator Stuck - Component or system operation obstructed or blocked: Action

NOTE: If any rear differential locking motor actuator brake or motor position sensor faults are also logged these should be investigated first

Refer to the electrical circuit diagrams and check the resistance of the rear differential locking motor clutch actuation motor circuit (resistance should be within the range of 1.8 Ohms). Repair circuit as required. Clear DTC and retest
If resistance is within range, clear DTCs then carry out the guided diagnostic routine using the manufacturers approved diagnostic system. Clear DTCs, cycle ignition and retest
If fault persists, check and install a new rear differential locking motor as required
