Electrical Diagnostics
Electrical fault diagnosis for every make we service. Failing sensors, wiring shorts, parasitic draws, module communication — we find the cause.
Electrical faults take real diagnosis
Modern vehicles contain a lot of control modules communicating over internal networks. An electrical fault can show up as a warning light, an intermittent no-start, a dead window, or a draining battery — and the symptom rarely points straight at the cause.
OREC Imports uses manufacturer-spec diagnostic platforms to read module-to-module communication, review coding, and perform guided test procedures specific to the vehicle.
What we diagnose
- Battery drain (parasitic draw) — systematic current draw testing to isolate which module or circuit is at fault
- CAN bus faults — communication errors between modules
- Sensor failures — MAF, MAP, O2, knock, crankshaft/camshaft position, ABS, and more
- Comfort and convenience systems — windows, sunroof, central locking, mirrors
- Instrument cluster and gauge faults
- Lighting system faults — adaptive headlights, LED driver failures
- Climate control module and blend door actuator faults
Our electrical diagnostic process
- Vehicle scan — all modules, all fault codes, all live data
- Wiring diagram review with factory wiring diagram access for the makes we service
- Component testing: voltage, resistance, signal integrity
- Written report with root cause, recommended repair, and parts estimate
We don’t replace parts hoping something works. Every repair starts with a confirmed diagnosis.
