Electrical & OBD2 Diagnostics
Electrical & OBD2 Diagnostics in Ajman | Marwat Garage
Is your engine light on? Battery draining overnight? Windows stuck? Electrical issues are one of the most raging car problems and they seldom fix themselves. Search no more if you have been looking for a reputed auto electrical shop in Ajman. Marwat Garage — based in Industrial Area 2, Ajman provides full Electrical & OBD2 Diagnostics, car electrical repair and auto electrical services for all makes and models.
We use professional OBD2 diagnostic equipment to diagnose problems quickly before correctly resolving them — no guesswork, no wasted time or money. From a simple blown fuse to a detailed wiring harness repair, we can do everything under one roof.
What Is OBD2 Diagnostics — And Why Does Your Car Need It?
OBD2 (On the Board Diagnostics) is an internal computer system built in every automobile after 1996. Your automobile stores an error code and turns on a dashboard caution mild when any Henry Martyn Robert, transmission, sensors or digital systems fail.
Our skilled technicians at Marwat Garage connect a professional OBD2 scan tool to the diagnostic port of your vehicle, and accurately read those fault codes. Our workshop-grade equipment reads live data streams, identifies intermittent faults and presents the full picture of your vehicle’s electrical health unlike basic consumer-level Bluetooth OBD2 readers.
Which means that we fix the underlying reason — not just reset the warning light. This saves you cash, time and repetitive trips to a storage because of neglect service.
Our Electrical & OBD2 Diagnostic Services in Ajman
As Ajman’s leading car electrical workshop, we offer a full range of auto electrical services for every electrical system in your vehicle:
1. Computer Controlled Circuit Repairs
Your car’s ECU (Engine Control Unit) manages fuel injection, ignition timing, transmission, and much more.When circuit faults happen, your vehicle’s performance decreases immediately. Our car electricians run full ECU diagnostics, inspect circuit boards, calibrate sensors, and repair damaged connections to restore proper engine management.
Approx. Time: 2–3 hours.
2. Power Windows, Power Doors, Power Seats & Power Antennas
Stuck windows, doors that won’t lock, or a power seat that won’t adjust are both frustrating and a safety concern. We repair window regulators, door lock actuators, power seat motors, and antenna systems for all car types.
Approx. Time: 3–4 hours.
3. Electrical Shorts & Parasitic Draw Testing
An electrical short can silently drain your battery, repeatedly blow fuses, or create a fire risk. Our auto electrical repair team uses professional tools to locate short circuits, trace parasitic draws, and fix the actual root cause.
Approx. Time: up to 8 hours depending on complexity.
4. Re-Wiring for Harness Damage
Rodent damage, accidents, or general wear can severely damage a wiring harness — causing random electrical failures and stalling. We inspect the full harness, replace damaged wiring, and repair or replace connectors to restore reliable electrical flow.
Approx. Time: 3 hours.
5. Dash Gauges & Related Switch Service
If your speedometer, fuel gauge, temperature gauge, or instrument cluster lights are misbehaving, you’re driving without critical information. We diagnose and repair all dashboard gauge and switch faults, including cluster illumination issues.
Approx. Time: 5–6 hours.
6. Turn Signals, Flasher & Headlight Circuits
Indicators that do not flash, headlights that flicker, or DRLs that do not work are active road safety hazards. As your local car electrician near me, we diagnose indicator circuits, replace flasher relays, and handle full DRL and LED headlight repairs and conversions.
Approx. Time: 5 hours.
7. Window Wipers & Washers
In Ajman’s dusty, sandy conditions, faulty wipers reduce visibility dangerously. We repair intermittent wiper controls, wiper motors, linkage mechanisms, and washer pump systems to keep your view clear.
Approx. Time: 6 hours.
8. Keyless Entry System & Key Fob Re-Programming
Lost your key fob or does your remote no longer respond? Our electricians in Ajman program replacement key fobs, repair keyless entry receiver modules, and handle lost key replacement for most popular car brands — faster and far more affordable than a main dealership.
Approx. Time: 4 hours.
Car Alternator Repair & Battery Replacement in Ajman
One of the most common car electricity trouble repairs we see is a failing alternator. If the battery warning light is on, your headlights dim at idle or your batteries keep discharging flat — it is more likely to be an alternator (not a battery) fault.
We also offer same day car battery replacement in Ajman with quality batteries and warranty. And if your car alternator requires repair or replacement, our technicians complete every repair quickly with original parts so that your vehicle can hit the road again safely.

Frequently Asked Questions
Q1: What does an OBD2 diagnostic check cover?
An OBD2 scan reads fault codes stored in your vehicle’s computer, covering the engine, transmission, ABS, airbags, emissions system, and dozens of electronic sensors. It’s the fastest and most accurate way to identify the cause of any dashboard warning light.
Q2: How much does car electrical repair cost in Ajman?
Cost depends on the nature of the fault. Simple repairs like a fuse or bulb are very affordable. Complex jobs like wiring harness repair or ECU work take longer. At Marwat Garage, we always provide a clear cost estimate after diagnosis — before any work begins.
Q3: How long does an electrical diagnostic take?
A standard OBD2 scan and initial electrical check takes 30–60 minutes. Repair time varies by fault — from 1 hour for simple jobs to 6–8 hours for complex wiring issues. We keep you informed of the timeline throughout.
Q4: Why does my battery keep going flat even though it’s new?
A new battery draining repeatedly usually means either a faulty alternator not charging while driving, or a parasitic draw — something consuming power when the car is off. Both are diagnosed and repaired at Marwat Garage.
Q5: Can you reprogram a key fob for any car brand?
We program key fobs for most popular car brands. Call us with your car’s make, model, and year to confirm. In most cases it’s significantly cheaper than going to a main dealership.
Q6: Do you service European and American cars, not just Japanese?
Yes. Our auto electricians are trained on all major vehicle platforms — Japanese, European, American, Korean, and GCC-spec. Our OBD2 diagnostic tools are compatible with all vehicle types.
