About Our Electrical Service
Today's cars run on dozens of sensors, control modules, and kilometres of wiring. A single faulty sensor or loose connector can trigger warning lights, cut engine power, or leave you with a car that won't start. Guesswork only wastes money on parts you don't need.
At Porur MCC Motors, we start with a computerised OBD scan and live-data analysis, then trace the fault with multimeters and wiring diagrams. From ECM repair and reprogramming to alternators, starters, and accessory fitting — every electrical job is handled in-house.
ECM repair, not just replacement: We bench-test and repair faulty ECMs wherever possible — saving you a big dealer bill.

Warning Signs
Electrical faults get worse with time. Get a diagnosis as soon as you notice any of these signs.
A steady light needs a scan soon. A flashing light means a serious misfire — stop driving and call us.
Slow cranking, clicking sound, or no response usually points to battery, starter, or wiring issues.
Faulty sensors or ECM issues can put the engine in "limp mode" or make it stall in traffic.
Headlights dimming at idle or a battery warning light often means the alternator is not charging.
Repeated blown fuses or a burning plastic smell indicate a short circuit — get it checked immediately.
