Question

How do I fix code P1793 on a 2003 Dodge RAM 1500 5.7L?

Answer 1

The P1793 code indicates a communication problem Transmission Control Module (TCM) and the Powertrain Control Module (PCM). The wire circuit between the TCM and PCM needs to be tested to find the communication error. If no damaged wire is found, the next step is to check the TCM and PCM.
