2014 Dodge Ram 1500 DTC P1DF3?

Question

Looked everywhere for the answer to this code and ended up telling my customer to contact the Dodge dealer. I have never come across codes with letter in the middle. I run DTC checks regularly and hate telling my customers that I do not know. Any help you can give would be helpful. Thanks.

Answer 1

The purpose of the diagnostic is to monitor the time period of the Electronic Shift Module (ESM) initialization state. The Transmission Control Module (TCM) receives the status of the initialization state from the ESM on the Controller Area Network (CAN) bus while evaluating a counter in the TCM to determine if the initialization time is excessive.
