Frequently asked questions
Can you fix an intermittent electrical fault?
Yes. We use wiring diagrams, load testing, and wiggle testing to reproduce and isolate intermittent faults rather than throwing parts at them.
Do you reprogram control modules?
We reflash and update supported modules to correct software-related faults and apply manufacturer updates.
