Our CPC4 module repair process begins with a comprehensive diagnostic evaluation to identify the specific issues. We thoroughly inspect the module’s hardware and software for any faults. After detecting the root cause, we replace or repair defective components such as capacitors, transistors, or microchips. Next, we update or reflash the software to ensure it’s fully functional and up-to-date. Once the repair is complete, we run a series of rigorous tests to verify that the module is operating correctly under real-world conditions. This ensures your truck’s CPC4 module performs optimally before it's returned to you. The entire process is fast and efficient, minimizing downtime and getting your truck back on the road quickly.
We're located in Hartford, Connecticut, and if you're in Connecticut, Maine, Massachusetts, New Hampshire, or Rhode Island, we can resolve your issue in less than 24 hours.
We understand your truck needs to stay on the road, which is why we work as quickly as possible to get the job done.
We work around the clock, so if your truck breaks down at night and you can get the CPC unit to us, we can repair it overnight
