Great Wall Poer ABS Light On: What to Check First

Why Your Poer’s ABS Light Stays On

When the ABS light stays on continuously, the ABS module has detected a fault and disabled the anti-lock function. On a Great Wall Poer, the most common culprit is a wheel speed sensor — either the sensor itself, its connector, or the wiring running to that wheel. The module also needs a clean signal from the tone ring/reluctor ring on the hub, so dirt, rust, or a cracked ring can trigger the same warning. Less often, you’re looking at a failing ABS module, a voltage/earth issue, or a related brake system fault.

Check these first, in this order:

• Scan the ABS system for stored codes — that tells you which wheel or circuit the module is unhappy with.
• Inspect the wheel speed sensor and its connector at the affected wheel for damage, corrosion, or a loose plug.
• Trace the sensor harness for chafing, stretched wires, or water ingress, especially near the hub and suspension.
• Clean and inspect the tone ring and sensor tip; check for cracks, rust, or metal debris.
• Watch live wheel-speed data while slowly rolling — all four should match closely.

Is it safe to keep driving? If only the amber ABS light is on and the brakes feel normal, you can usually drive cautiously to a workshop — but remember the ABS may not intervene in a panic stop, so leave extra distance and avoid slippery conditions. If the red brake warning light is also on, the pedal feels soft or long, you hear grinding, or the brakes behave unpredictably, stop driving and get it checked immediately. A proper ABS scan and wheel-speed live-data check will save you guessing and point you to the right sensor or circuit before you start replacing parts.
