Set Condition

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

After the Auxiliary Fuel Pump is commanded on by the PCM, Fuel Level Sensor 1 reports a fuel level beyond a calibrated maximum threshold. The Auxiliary Fuel Pump should have been been commanded off to avoid over spill. The PCM thinks the transfer pump is stuck on and has sent a request to the BCM to turn off the Fuel Pump 2 On/Off Relay.
