Common ECU Rebuilds We get over 50 ECU’s daily being sent in for testing + repairs. Below is a small selection of some of the common ECU’s being sent in with common faults. We’re able to fully bench test all ECU’s and simulate the ECU as if it were still connected to the vehicle. We can extend testing to find faults that only occur when the engine is under load, when the engine is up to optimal temperature and even intermittent faults. If you suspect a faulty PCM unit and would like it tested and repaired then get in touch.
