ABS Warning Light on a BYD Song
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the ABS Warning Light Means on a BYD Song
On the BYD Song, an illuminated ABS symbol indicates the system found a fault — commonly a wheel speed sensor — and switched off ABS. You retain standard braking, but should have it checked so full safety function is restored.
How Urgent Is the ABS Warning Light?
In terms of priority, treat this as a high concern on your BYD Song. The single most useful thing you can observe is whether the ABS Warning Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the BYD Song drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
Common Symptoms Alongside the ABS Warning Light
When the ABS Warning Light shows up on a BYD Song, it rarely arrives completely alone — there are usually subtle clues if you know where to look. Drivers often notice a change in how the BYD Song responds, an unfamiliar sound, or a warning message on the instrument cluster. Cataloguing these symptoms is not busywork; each one narrows the list of likely causes and helps a technician zero in on the real fault instead of replacing parts on a hunch.
- ABS light steady on the dash
- Anti-lock not engaging on hard stops
- Sometimes paired with the traction/ESP light
- Speedometer glitches (shared sensor)
What Causes the ABS Warning Light to Come On?
Why did the ABS Warning Light come on in your BYD Song? The honest answer is 'it depends', but the possibilities cluster into a recognisable set of causes. Knowing them in advance means you will not be caught off guard by a diagnosis, and it lets you sanity-check any repair quote against what commonly goes wrong on the BYD Song.
- Faulty wheel speed sensor
- Damaged sensor wiring or tone ring
- Low brake fluid
- ABS module or pump fault
- Blown fuse
How to Fix the ABS Warning Light on a BYD Song
The right way to clear the ABS Warning Light on a BYD Song is to fix the underlying cause, not just reset the symbol. Work through the steps below in order — they move from the simplest checks any driver can do to the diagnostic work best left to a scan tool. Following this sequence prevents the classic mistake of replacing expensive parts before ruling out the cheap, common problems first.
- Check the brake fluid level first
- Scan for ABS (C-series) trouble codes
- Inspect wheel speed sensors and wiring for damage
- Clean or replace the faulty sensor / tone ring
- Clear codes and road-test to confirm ABS returns
Is It Safe to Drive With the ABS Warning Light On?
Whether it is safe to keep driving your BYD Song with the ABS Warning Light on comes down to urgency (high) and behaviour. As a rule, if the light is red or flashing, or the BYD Song is running poorly, stop somewhere safe and arrange help rather than pushing on. If the light is amber and the car drives normally, you generally have time to reach a workshop — but 'have time' is not the same as 'ignore it', so book a check promptly.
Diagnostic Trouble Codes Linked to the ABS Warning Light
If you scan a BYD Song showing this light, these are the OBD-II trouble codes most commonly associated with it. The code you actually retrieve is what pinpoints the repair.
| Code | Meaning |
|---|---|
C0035 |
Left Front Wheel Speed Sensor Circuit The ABS module has lost a valid signal from the left front wheel speed sensor. |
C0110 |
ABS Pump Motor Circuit Malfunction The ABS hydraulic pump motor circuit has failed, disabling anti-lock function. |
Professional Mechanic Tips
Corrosion on the sensor tip or tone ring is a common, cheap cause — worth cleaning before condemning the module.
On a BYD Song, the ABS and traction lights often come on together from a single wheel speed sensor — fix the sensor and both usually clear.
Frequently Asked Questions
Why is the ABS Warning Light on in my BYD Song?
The ABS Warning Light illuminates on a BYD Song when the vehicle detects a condition in the related system that is outside its normal range. The exact reason can vary from something as minor as a loose connection to a component that needs replacing, which is why reading the stored trouble codes is the reliable way to know for certain.
Can I keep driving with the ABS Warning Light on?
It depends on the urgency (high) and how your BYD Song is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
How much does it cost to fix the ABS Warning Light on a BYD Song?
There is no single price for the ABS Warning Light on a BYD Song; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the ABS Warning Light reset itself on a BYD Song?
If the trigger was temporary, a BYD Song may turn the ABS Warning Light off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
