The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
While diagnosing a Vehicle Stability Enhancement System (VSES) related concern on the above mentioned vehicles, the Technician may notice that the Left Front (LF) Wheel Speed Sensor (WSS) is displayed twice and there is no display for the Left Rear (LR) Wheel Speed Sensor.
The data will be corrected for the next Tech 2 release. Technicians can use the WSS data contained under ABS and TCS for correct WSS readings until that time.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
