- [DT12 Trans Chafe](/bulletins/10190020.md), 2021-04-08, Service bulletin: EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; POWER TRAIN. DTNA received a field notification on multiple units regarding diagnostic fault codes that were found to be causing 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.

The new mat should not interfere with safety\-critical equipment, such as foot pedals.
