Product Details

This repair service is for the CPC4 (Common Powertrain Controller) module from a 2014, 2015, 2016, 2017, 2018, 2019 Freightliner Cascadia trucks. Our repair is designed to solve the most common issues with the CPC4 module for this vehicle including:

  • No start / Intermittent start
  • Dead throttle / Intermittent throttle 
  • CPC reads as a different module (reads as CPC2, TCM, etc.)
  • CPC Hardware Failure Fault Code SPN 609 FMI 12

Our repair also address the following issues when they are associated with communication failure:

  • Check Engine Light is on
  • ABS Light staying on
  • DEF Light staying on
  • Instrument Cluster loses communication

We combine our circuit board repair expertise with state of the art tools for a complete and robust repair of the problems that plague the CPC modules. Unfortunately DIY solutions and repair shops with inferior tools and techniques often cause more damage to these controllers.  If a repair has already been attempted by a non-qualified facility, we will evaluate the damage to determine if additional costs are necessary.  In such cases, we will contact you before performing the repair to discuss your options.  If there are additional costs due to a prior repair attempt and you choose not to proceed with the repair, a full refund will be issued.  

Sometimes when the circuitry on your CPC4 fails it also corrupts the programming on the circuit board. Despite that failure, we are able to fully repair this module by reprogramming it to the latest OEM configuration for your vehicle based on your particular VIN.  Your CPC4 will be ready to install and use immediately without additional programming. 

This repair is also for the following alternate and replacement part numbers:
