A buddy of mine has a '92 C1500 Chevy, 350/auto. Lately it's been idling rough and has some hesitation under acceleration. A code check produced 54 for the "quad driver module" or a fuel pump/relay low-voltage scenario.
The symptoms for the "quad driver module" failing match his truck perfectly...but neither of us has ever heard of it.
What is it, where is it, and what does it do?
