If a warning light disappears and then returns, your car has stored fault data. A proper diagnostic session lets us read codes, review freeze-frames & live data, run actuator tests, and pinpoint the real cause so you don’t waste money on guesses.
Common lights that should trigger a scan
Check Engine / MIL: misfires, fuel trims, O2/MAF/MAP, EVAP leaks
ABS / Brake: wheel speed sensors, tone rings, hydraulic modulator
SRS / Airbag: pretensioners, occupancy sensors, connectors/wiring
Hybrid System / HV Battery: battery modules, relays, inverter temps
Don’t just clear codes. Freeze-frame data tells us what the car saw when it failed. Repeatedly clearing can hide the root cause and delay repairs.
