WARNING LIGHTS ON AFTER AN ACCIDENT?
Dashboard lights after a crash are the car filing its own damage report — read them by severity. An airbag light means the restraint system has a fault and may not protect you in the next crash: inspect before relying on the car. ABS or brake lights mean braking help may be degraded — same urgency. A check-engine light with flashing, or temperature/oil warnings, mean stop driving now. And the reverse is just as important: no lights doesn’t mean no damage — plenty of crash faults log silently as codes without lighting the dash, which is why a pre-repair diagnostic scan is standard practice at DG (free to you: billed to insurance on covered repairs, on us for estimate-only visits). Every light traced to the crash is claim damage, and the scan report is the document that proves it.
The Longer Answer
WHAT EACH LIGHT MEANS AFTER A CRASH — AND WHAT THE SCAN SEES
Triage by light. The airbag light is the one you never gamble on: it means the restraint system found a fault — a triggered sensor, a wiring problem, a module error — and until it’s diagnosed, you should assume the bags may not deploy when needed. If bags did deploy, the car has bigger decisions pending anyway (that math has its own guide); if they didn’t but the light is on, the crash likely disturbed a sensor or connector, and everything in that system is repaired to one standard here: genuine parts, always, per the manufacturer’s procedure. ABS and brake-system lights after impact suggest a wheel-speed sensor, tone ring, or harness casualty — the car still brakes, but its anti-lock and stability help may be offline exactly when a panic stop needs them. Flashing check-engine, temperature, or oil pressure: park it — those protect the engine from becoming the crash’s most expensive casualty, and driving through them can turn a claimable repair into an argument.
Now the quieter half of the story. Modern cars log faults constantly, and a crash can set dozens of codes — sensor disconnects, module resets, out-of-range readings — of which only the serious few light the dash. That’s why the industry standard, and ours, is the pre-repair scan: before work begins, every module gets read, and the fault list becomes part of the estimate — evidence of electronic damage the eye can’t see, documented while the connection to the crash is fresh. After repair, the post-repair scan proves the systems woke up clean, and on anything that disturbed a camera or radar, calibration finishes the job through our specialist partners with the printed report verified before delivery. Both scans are free to you — billed to insurance on covered repairs, on us if you’re only here for an estimate.
The claims logic writes itself from there: lights and codes traced to the crash are crash damage — sensors, harnesses, modules, and the labor to diagnose them belong on the claim, entering through the estimate or the supplement like any hidden damage. What weakens that position is time and silence: driving months on an airbag light, then trying to attach it to the claim, invites the “pre-existing” argument. The strong move costs nothing — scan early, document the fault list, report symptoms promptly. If a light came on with your crash, send us a photo of the dash along with the damage; it genuinely helps the first look.
