Correction
-
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.
A revised calibration will be available in the December 2020 timeframe 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.
