ESP / Stability Control Light on a BYD Han
Investigate soon. Driving short distances is generally okay, but book a diagnostic check.
What the ESP / Stability Control Light Means on a BYD Han
On the BYD Han, this light flashing means stability control is intervening to keep the car composed; a steady light means the system is off or has detected a fault and cannot assist.
How Urgent Is the ESP / Stability Control Light?
In terms of priority, treat this as a moderate concern on your BYD Han. The single most useful thing you can observe is whether the ESP / Stability Control 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 Han drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
Common Symptoms Alongside the ESP / Stability Control Light
When the ESP / Stability Control Light shows up on a BYD Han, 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 Han 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.
- Flashes during hard cornering or slippery conditions
- Steady light means ESP off or faulty
- Possible reduced cornering assistance
- May pair with ABS/traction lights
What Causes the ESP / Stability Control Light to Come On?
The ESP / Stability Control Light on the BYD Han can be triggered by several conditions, and experienced technicians work through them from most to least likely. Some causes are trivial and cost almost nothing to correct, while others require replacing a sensor or component. The list below reflects what actually turns this light on in the real world, so you can gauge whether you are likely facing a quick fix or a workshop visit.
- ESP switched off manually
- Wheel speed sensor fault
- Steering angle sensor needs calibration
- Brake light switch fault
- ABS module fault
How to Fix the ESP / Stability Control Light on a BYD Han
To resolve the ESP / Stability Control Light on your BYD Han, resist the urge to simply disconnect the battery and hope it stays off. A warning that is cleared without addressing the cause almost always returns. The step-by-step approach below is the same logical order a professional follows on the BYD Han: confirm the basics, read the stored codes, then target the actual fault.
- Check the ESP off button has not been pressed
- Restart the car and drive a short distance
- Scan for stability-control codes
- Recalibrate the steering angle sensor if needed
- Repair the underlying sensor or switch fault
Is It Safe to Drive With the ESP / Stability Control Light On?
Drivers ask this constantly, and the answer for the BYD Han is nuanced. A steady amber ESP / Stability Control Light with no change in how the car drives usually means you can continue carefully and get it looked at soon. A red or flashing ESP / Stability Control Light, unusual noises, warning messages, or a drop in performance are your cue to stop the BYD Han safely and avoid further driving until the cause is known.
Diagnostic Trouble Codes Linked to the ESP / Stability Control Light
If you scan a BYD Han 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. |

A faulty brake light switch is a sneaky cause of the ESP light on many cars — cheap to fix and easy to miss.
Frequently Asked Questions
Why is the ESP / Stability Control Light on in my BYD Han?
Your BYD Han turned on the ESP / Stability Control Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the ESP / Stability Control Light on?
For a BYD Han, a steady amber ESP / Stability Control Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the ESP / Stability Control Light on a BYD Han?
There is no single price for the ESP / Stability Control Light on a BYD Han; 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 ESP / Stability Control Light reset itself on a BYD Han?
Sometimes the ESP / Stability Control Light on a BYD Han clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
