If the servo motor is damaged, replace section of cable including electric plug connection and transfer case servo motor.
122-Q3V5G-102017-10-15. Service bulletin. ELECTRICAL SYSTEM. Cause: Clicking noises can come from around the transfer case when manoeuvring the vehicle (or driving slowly) due to activation of the transfer case servo motor. Remedial Action: Before doing any other work, the symptommust be simulated using a test procedure. (Opening the door windows can be helpful when evaluating noises). 1 Conditions for the first test procedure: ? Activate the Start/Stop function and ? deactivate all sources of noise in the vehicle (Entertainment, ventilation, etc.). ? A multi-story parking garage can be useful for acoustic reverberation. ? Onastraight stretch ? fromspeeds less than 10mph (20 km/h) ? brake the vehicle to a standstill. ? The best way of finding the clicking noise is by driving slowly and then stopping the vehicle.
