Professional Car Computer Repair Near You
Modern cars are computers on wheels. A simple “Check Engine Light” could mean anything from a loose fuel cap to a critical engine failure. Instead of paying expensive towing fees to drag your car to a dealership, Namma Road Service brings the diagnostic workshop to you. We are Bangalore’s leading mobile car ECM repair and scanning service provider.
Whether you are dealing with a “Rat Bite Wiring Issue” in HSR Layout or a sudden “Limp Mode” failure on the Bangalore-Mysore Highway, our certified auto-electricians are equipped with dealer-level OBD-II scanners (Launch/Autel) to pinpoint the fault in minutes. We handle Engine Control Modules (ECM), Transmission Control Modules (TCM), ABS Systems, and Airbag Modules for all Indian and imported cars.
Why is Your Check Engine Light On?
Rodent (Rat) Wiring Damage
The #1 cause of electrical failure in Bangalore. Rats chew through critical engine harnesses, causing multiple sensor failures. We repair wires professionally using heat-shrink tubing.
ECM / ECU Software Error
Corrupted software or water damage to the Engine Control Unit can prevent your car from starting. We perform on-site diagnosis and minor board-level troubleshooting.
Faulty O2 / MAF Sensors
Bad Oxygen sensors or Mass Air Flow sensors cause poor mileage and rough idling. We clean or replace these sensors at your location.
Common Error Codes We Fix (DTC List)
If you have a cheap scanner, you might see these codes. We not only read them but fix the root cause:
| Diagnostic Code | Problem Description | Our Professional Fix |
|---|---|---|
| P0300 | Random/Multiple Cylinder Misfire | Check Spark Plugs & Ignition Coils |
| P0420 | Catalytic Converter Efficiency Below Threshold | O2 Sensor Cleaning / Exhaust Check |
| P0171 | System Too Lean (Fuel/Air Mix) | Check Vacuum Leaks / MAF Sensor |
| U0100 | Lost Communication with ECM/PCM | Check Wiring Harness / Fuse Box |
Our Diagnostic Process
Full System Scan
We connect a professional-grade OBD scanner to read active and pending Fault Codes (DTCs) from the car’s brain.
Live Data Stream
We don’t just guess. We monitor live data like fuel trim, battery voltage, and ignition timing while the engine is running.
Physical Inspection
We visually inspect wiring harnesses, fuses, and relays for physical damage, corrosion, or rat bites.
Repair & Reset
After fixing the wire or replacing the sensor, we execute a “Hard Reset” to clear the warning lights from the dashboard.

Frequently Asked Questions
Can you fix rat bite damage at my home?
Yes. 90% of rodent damage involves external wiring repairs which we can do on-site. If the damage is deep inside the dashboard, we may recommend towing to our workshop for dismantling.
My car is in “Limp Mode” (Won’t accelerate). What to do?
Limp mode is a safety feature triggered by the ECM to protect the engine. Do not drive long distances. Call us for a scan; it is often a simple sensor failure that we can bypass or fix on-spot.
Do you repair water-damaged ECMs?
We can attempt to clean and dry the ECM circuit board using contact cleaners. If the ICs are shorted, we take the ECM to our lab for chip-level repair or cloning.
Why is my Airbag light blinking?
This usually indicates a loose connection under the seat or a faulty clock spring. We can scan the SRS module to find the exact loose coupler and fix it.
