Set Condition

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

Whenever the RF Hub performs a handshake with the PCM and does not receive a seed response from the PCM, this code will set. If there are any active CAN Bus DTCs (U0001-00 or U0002-00), this code will not set.

One of the most probable causes for this code to set is a blown fuse or bent pins on the PCM RUN/START circuits. The result is the PCM does not know the ignition has been turned to the RUN position and does not know to respond to the seed request. Check the PCM RUN/START circuits to the PCM before proceeding with this procedure.
