Electrical Services & Diagnostics

Modern vehicles contain dozens of onboard computers (ECUs) communicating via CAN-Bus. Minor sensor drifts or loose ground wires can trigger check engine lights, fail-safe modes, or accessory failures. Generic mechanics often replace expensive modules blindly. Vellore Auto Garage utilizes official Bosch test routines, checking voltages, ground signals, and resistance to find and fix the exact wire fault.

What is Included:

  • Computerized System Scans: Full interrogation of all onboard modules (ABS, SRS, ECM, BCM, HVAC) and error code clearing.
  • Bosch Battery Service: Testing cold cranking amps (CCA), internal resistance, replacement with high-performance Bosch batteries, and recycling.
  • Alternator & Starter Motor Overhaul: Charging system load tests, diode checking, and brush replacement.
  • Wiring & Sensor Diagnosis: Fixing short circuits, blown fuses, parasitic draws, and replacing failed crankshaft, mass airflow, or oxygen sensors.

Common Warning Signs:

Electrical issues should be diagnosed early to prevent damage to expensive ECUs. Contact us if you notice:

  • A battery warning light or "check charging system" message on the dashboard.
  • Engine crank is sluggish, clicking, or refuses to start.
  • Headlights or dashboard lights flickering or dimming during operation.
  • Accessories like power windows, central locking, or infotainment systems behaving erratically.

Frequently Asked Questions

How long does a car battery typically last?
A standard car battery lasts between 3 and 5 years depending on heat, usage, and electrical loads. Vellore Auto Garage recommends checking your battery's health once a year after it reaches 3 years of age.
What are the signs of a failing car alternator?
Signs of a failing alternator include dim or overly bright headlights, a battery warning light on your dashboard, electrical accessories stalling (radio, windows), and a battery that dies repeatedly even after being jump-started.
Can a diagnostic tool detect electrical short circuits?
Yes, our advanced Bosch diagnostic scanners read trouble codes from the Body Control Module (BCM) and other computers, pointing technicians to the exact circuit or sensor that has failed.
Why does my car battery drain overnight?
Overnight battery drains are usually caused by a 'parasitic draw' (such as a glovebox light remaining on or an aftermarket accessory drawing current) or internally shorted cells within an older battery.
