Cummins ISM CM875 (2003-06) Fault Code: 386 PID...

High voltage on the (+) 5 volt supply line can be caused by a short to battery voltage in the engine harness or connectors, or a malfinctioning ECM. Possible repair:...

Cummins ISM CM875 (2003-06) Fault Code: 352 PID...

Low voltage on the +5 volt supply wire can be caused by a short circuit to ground in a supply wire, a short circuit between a supply wire and a...

Cummins ISM CM875 (2003-06) Fault Code: 343 PID...

This fault can also be caused by resistance in the ECM battery supply (+) or (-) circuits. Resistance in these circuits can cause the voltage level at the ECM input...

Cummins ISM CM875 (2003-06) Fault Code: 341 PID...

The ECM is connected to the battery by the ECM power harness. This direct link provides a constant power supply for the ECM. The location of the battery will vary...

Cummins ISM CM875 (2003-06) Fault Code: 339 PID...

The ECM monitors the voltage level on this circuit. This fault code is logged if it detects a low voltage when the relay signal is commanded on. This fault code...

Cummins ISM CM875 (2003-06) Fault Code: 338 PID...

The ECM monitors the voltage level on this circuit. If it detects a voltage when the signal is commanded OFF, it records this fault code. Possible causes: 1)ECM Idle Shutdown...
