Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Good afternoon, P1693 is a basic code that means that there is a code in the other companion module such as the engine controller (cummins) or the powertrain control module (dodge). Inorder to check it further you will need to use a scanner that can access both the Cummins and Dodge control modules to see what codes are found. Other wise symptoms alone are not enough to accurately diag. you problems. The code or codes that you find may or maynot be related to the trans concern.

How can this code stop the transmission from shifting. It appears that the transmission is having a problem. Can a DIY'er fix this problem.
I will look for the additional codes and will reply.
With the correct scanner, when you try to go into the engine controller it will give you two options......(1) cummins module or (2) powertrain module (dodge). The scanner you are using may not be capable of this. If there was a code in the cummins module then there would be a code P1693 in the PCM letting you know. If there is no code in the PCM then where was the original P1693 found?
