What Our Diagnostic Service Covers
Our diagnostic process goes beyond just reading error codes. We conduct a comprehensive analysis to uncover the exact cause of faults.
1. Engine Diagnostics
We connect our diagnostic tools to your vehicle’s onboard computer to read trouble codes. From rough idling and poor fuel economy to check-engine light warnings, we detect and fix the root cause.
2. Transmission System Scanning
Transmission issues can be tricky — slipping gears or hesitation may point to electrical or mechanical problems. We accurately identify the fault before repair.
3. ABS & Brake System Testing
We test sensors, wiring, and brake modules to ensure your anti-lock braking system functions correctly and safely.
4. Airbag & Safety System Diagnostics
We check the SRS (airbag) system for faults and ensure safety systems are properly reprogrammed after any repair.
5. Battery & Charging System Check
We inspect alternator output, battery health, and wiring to prevent sudden breakdowns — a common issue on Lagos roads.
6. Sensor & ECU Calibration
From oxygen sensors to throttle and temperature sensors, we ensure accurate readings and recalibrate your ECU (Engine Control Unit) when needed.
