Mitsubishi Galant Fortis ABS Warning Light Malaysia
An illuminated ABS warning light on the Galant Fortis means the ABS system has detected a fault and is temporarily disabled — normal braking still functions, but the anti-lock feature will not activate. The most common causes on high-mileage units are a faulty wheel speed sensor (often caused by a damaged sensor ring or corroded connector) or a failing ABS pump. Diagnose with a proper scan tool before replacing parts. Wheel speed sensor replacement is usually straightforward and inexpensive.
The ABS (Anti-lock Braking System) warning light means the system has detected a fault and has disabled itself. Your brakes still work — but you lose the anti-lock function that prevents wheel lock-up during emergency stops. In Malaysia's wet roads and heavy traffic, this is a safety issue worth fixing promptly.
Common causes of ABS light
- Wheel speed sensor fault (most common) — sensor dirty, damaged, or failed
- ABS reluctor ring (tone ring) damaged — the toothed ring that the sensor reads
- Low brake fluid level triggering combined ABS/brake warning
- ABS pump or control module fault — less common but more expensive to fix
- Corroded or broken wiring to wheel speed sensors — common on older cars
Diagnosis and repair cost
Wheel speed sensor replacement: RM 150–400 per corner including the sensor and labour. ABS reluctor ring: RM 80–250 per wheel. The control module is expensive — RM 800–2,500 for most cars — but module faults are the minority of ABS issues.
At 4M Car Care, we scan all four wheel speed sensors simultaneously and pinpoint which corner has the issue before any parts are ordered. This prevents unnecessary replacements.
