ABS Light Stuck On in Your Chery Arrizo 5? What a Mechanic Checks First

What That Glowing ABS Light Really Means

On the Chery Arrizo 5, the ABS lamp staying on continuously means the anti-lock control module has logged a fault and switched the system off to protect itself. The good news: your normal hydraulic brakes are still working, so you are not brakeless. The bad news: you have lost anti-lock assistance, and on most Arrizo 5 variants you also lose EBD and traction control functions that share the same wheel speed data. The single most common culprit by a wide margin is a wheel speed sensor — either the sensor itself, the tone ring it reads, or the wiring and connector between them and the module.

Likely Causes, Ranked by How Often We See Them

• Faulty wheel speed sensor (front or rear) — the classic. Dirt, metal debris, moisture ingress or an internal break in the coil.
• Damaged or corroded sensor wiring/connector — often after a wheel bearing job, suspension repair, or road salt exposure.
• Dirty or damaged tone ring / magnetic encoder ring — on Arrizo 5 models with the encoder built into the hub bearing, a worn bearing can wipe out the signal.
• Excessive wheel bearing play or debris buildup — changes the air gap the sensor needs to read correctly.
• Module, fuse, or low battery voltage issues — less common, but low voltage during cranking can set ABS codes too.

What to Check First, Step by Step

Start with a proper scan tool that reads ABS codes — not just a generic OBD-II engine reader. The code will usually tell you which corner is complaining (for example, front left). From there, pull live wheel speed data and drive slowly: all four wheels should read nearly identical. If one drops to zero or jumps erratically, you have found your circuit. Then do the physical inspection: lift the car, unplug the sensor, check the connector for green corrosion or moisture, look for a chafed or stretched harness near the strut and brake line, and check the tone ring for cracks, missing teeth, or heavy metallic sludge. A quick resistance and AC voltage test while spinning the wheel confirms whether the sensor is alive. If the sensor and ring look clean and the harness is intact, suspect the bearing or the module — but clean the ring and clear the code first, because a surprising number of these lights go out after a simple sensor replacement and code reset.

Is It Safe to Keep Driving?

Short answer: you can drive, but you should not put it off for long. Your standard brakes will stop the car normally in everyday driving, but in a hard panic stop or on wet, gravelly, or icy roads the wheels can lock up, and you lose the steering control that ABS gives you. You also lose traction control, which matters more in the rain. Drive gently, increase your following distance, avoid heavy braking, and get it diagnosed within a few days. If the brake pedal feels spongy, sinks toward the floor, or the car pulls hard to one side when braking, stop driving and get it towed — that is a hydraulic problem, not just a sensor. Otherwise, a wheel speed sensor fix on an Arrizo 5 is usually an affordable, same-day repair.
