SERVICE:
Baseline:
First please watch the baseline video (TJ 36665 Normal Sound.mp4) for an example of a normal
ERAD sound. Use a headset or earphones to hear the sound clearly.
If a customer is driving in electric mode and experiences abnormal noise from the rear of the vehicle
that increases with vehicle speed (see example video TJ 36665 Faulty Motor Bearing Noise.mp4) it
is most likely an electrical motor bearing issue. No DTCs (Diagnostic Trouble Codes) will be stored
and no messages will appear in the DIM (Driver Information Module).
In these cases, the Bearing Kit, function group 4601, should be replaced. It is not necessary to
replace the complete ERAD motor.
Warranty claim info:
To get a warranty claim accepted for a job described in this TJ, use the corresponding VST OP
number stated in this TJ.
Note that the TJ number must be stated in the repair order text.
