issues to the After Treatment Control Module (ACM). These fault codes indicated that the ACM communication message was not received by the Motor Control Module (MCM) which in certain cases, led to a 25% engine de-rate situation. Further diagnosis revealed that the DT12 wiring harness was chafing and contacting the transmission TCU case. To reduce potential chafing areas, the proposed short-term containment was to route the wiring harness using additional tie straps. This communication applies to Freightliner and Western Star vehicles built with DT12 transmissions.

Though the back-up light harness is long enough to connect to the backup light switch, it may be short enough that the wire seals in the connector can be stressed. Moisture entering through the seals can cause corrosion, resulting in a bad connection and/or failure of the switch. As a result, backup lights and, if equipped, the backup alarm, may not function when the vehicle is shifted into reverse.
