Condition |
Some customers may comment that there is a Service Axle message displayed and possible loss of limited slip differential function. |
|
Cause |
This condition occurs when C1135 symptom byte 92 is set in the K164 Differential Control Module (DCM) |
Engineering has identified a software anomaly that causes the DTC to set prematurely. If code C1135.92 is in History, clear codes using GDS2 and take no further action. Do not replace the K164 Differential Control Module.
After clearing the DTC, the vehicle is safe to drive and can be returned to the customer.
A revised calibration is expected to be available in the first quarter of 2021 to address this condition.
A Bulletin will be released to replace this PI when the calibration is available
Note: If the DTC is Current, continue with published Service Information diagnostics.
