Mitsubishi Pajero Sport ABS Warning Light Malaysia
Pajero Sport ABS warning most common cause: wheel speed sensor contamination from mud and off-road debris. After heavy off-road use, inspect and clean all four wheel speed sensors. Sensor gap and wiring condition are the primary failure points. 4WD ABS integrates with the Super Select system — a 4WD-related fault may trigger the ABS light alongside the 4WD warning. If both lights appear together, use MUT-III to read 4WD system codes. ABS pump or hydraulic modulator failure is less common but significantly more expensive to address.
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.
