Electrical and computer diagnosis is the other half of what we are known for. Difficult faults are the ones we like.
Modern vehicles are networks on wheels, and a single failing module or corroded ground can produce a page of unrelated symptoms. Reading codes is where diagnosis starts, not where it ends. We use factory-level scan tools, wiring diagrams, and a scope to find the actual fault instead of replacing the part the code happens to name.
This is work other shops send our way. We handle check engine light diagnosis, parasitic battery draws, charging and starting system faults, wiring repair and harness work, module communication problems, lighting faults, power accessory failures, and car key programming on select models. Rick Davis was involved in developing aftermarket access to vehicle antitheft security systems, which is the kind of background that matters here.
You get the diagnostic findings in writing before any repair is authorized.
A steady light is not an emergency, but it usually means the engine is running outside specification, which costs fuel and can damage the catalytic converter. A flashing light means stop driving. Either way, get it read.
That is a common reason people end up here. Repeat failures usually mean the original diagnosis stopped at the code. We start over with proper testing.
