What This Module Controls
The module manages fuel delivery, injection timing and emission control. In addition, it reads the sensor signals and runs the engine protection strategy. It also stores the fault codes that your diagnostic tool reads during service.
Faults Our Caterpillar C11 C13 ECM Repair Solves
Typical symptoms are no start, derate, intermittent shutdown and loss of communication with the diagnostic tool. Water intrusion, vibration and corrosion on the board cause many of these failures. However, every unit is different, so the bench diagnosis defines what needs repair.
How the Repair Works
First, we inspect and clean the board under magnification. Then we test it on our bench, locate the damaged components and replace them. Finally, we test the module again before it goes back to you.
Our repair covers the module hardware. We do not modify the software. However, the bench diagnosis checks whether the damage affected the software, and we let you know the result.
What You Receive Back
After the Caterpillar C11 C13 ECM Repair, you receive your own module, bench tested. Return shipping of the repaired unit is free, and we send it with tracking from our shop in Mount Dora, Florida.
Warranty on the Caterpillar C11 C13 ECM Repair
The repaired module carries a one-year warranty on the hardware. In addition, our technical team is available if the engine behaves differently once the module is back in place.
