Release Date:

Symptom/Vehicle Issue: Check Engine Light On, Service Shifter Message, No Crank
No Start. Transmission Wiring Harness Chaffed Or Pinched Near Exhaust DPF
Discussion: Initial complaint is that the Check Engine Light is illuminated, Service
Shifter Message is displayed, and/or a crank no start condition exists. Upon scanning
the vehicle for DTC’s you may find one or more of the following: P2453, P2454, P0335,
P0336, P242B, P242C, U0074, U11C3.
Diagnosis: Inspect the wiring harness near connector XY230A leading down to the
transmission. The harness routing may allow the wiring to make contact with the sharp
edge of the DPF gasket flange. It has also been found that the wiring harness could be
routed close to the exhaust causing chaffing. Both of these situations could result in
damage to the harness and a potential open or short.
