What to do if your Dodge Ram says no bus?
Using a Digital Volt Ohm Meter (DVOM) or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor. If 5v is not present, unplug the Camshaft Position (CMP) sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit.

What’s the No Bus message on my 2002 Dakota?
I guess 2014 is the year for 2002 Dakotas to shred their PCM units…. I have the same no bus message on odometer. Truck will turn over, no bus message blinks a few times and then constant. I have looked at several forums for answers, haven’t found any answers that provide enough information. Help! I had the same thing wrong with my 2002 DAKOTA.

What happens when the 5V power supply is shorted?
The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 seconds after the short is removed. Using a Digital Volt Ohm Meter (DVOM) or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor.
