Common Powertrain Controller (CPC) Repairs

The Common Powertrain Controller (CPC) is a module used with Detroit Diesel engines. The CPC is the interface between the Motor Control Module (MCM) and the vehicle electronics system, acting as a communication gateway.

The role of the MCM is to determine and evaluate all the parameters required by the engine to function. The MCM calculates the load levels, ambient conditions and evaluates other sensors that the engine requires to function.

The values determined by the MCM are relayed over a CAN interface to the rest of the vehicle. The CPC4 functions as the gateway for the MCM to replay the information which allows the operator to control the vehicle. The CPC unit accepts other analog and digital inputs as well from the throttle, ABS, EBM, cooler level, etc which is also required by the engine and operator.

The CPC is an important gateway in the vehicle between a variety of modules. Once the CPC fails the communication between these modules is disrupted and the vehicle typically shuts down the throttle. Other forms of failure in the CPC module include:

The vehicle engine does not want to start
CPC module not correctly identified
CPC hardware failure with SPN 609 FMI 12 fault code
Check engine light is on
ABS engine light due to failed CPC4 module
DEF engine light is on
Vehicle not starting
Dead throttle

Once the repaired CPC unit is reinstalled into the vehicle no additional programming is required. The vehicle will be 100% back to normal and the unit is 100% plug and play.

Service highlight:
100% plug and play CPC- There is no other programming required once repaired
2-4 day turn around - Most of our repairs are done within 2 days, excluding shipping
6-month warranty - All our CPC repairs come with a 6-month warranty.
