What is the ABS warning on a Honda Accord?

When the ABS warning light appears on a Honda Accord, it signals a fault in the anti-lock braking system. Normal braking still works, but the anti-lock feature may be disabled until the issue is addressed.

What the ABS warning light means

The ABS warning light, usually an amber or yellow “ABS” icon, informs you that the vehicle’s anti-lock braking system has detected a fault. ABS helps prevent wheel lock during hard braking, enabling you to steer while braking. In most Accords, the light will come on briefly when you turn the key and should go off; if it stays lit while driving, the ABS is not functioning as designed. The brake system warning light (a red exclamation point inside a circle) is a separate indicator and can appear for other brake-related problems.

How the lights differ

Pay attention to which lights are on together. If only the ABS light is on, the ABS is disabled but standard braking remains possible. If the brake warning light is also on, there may be a more serious issue with hydraulic brake pressure or fluid level.

Common causes

Several issues can trigger the ABS warning on a Honda Accord. The following list highlights typical culprits you may encounter.

• Faulty wheel speed sensor(s) or damaged wiring near a wheel


• ABS tone rings or reluctor rings damaged or dirty


• Malfunctioning ABS hydraulic control unit or pump


• Low brake fluid level or air in the brake lines



• Electrical fault or a stored diagnostic trouble code in the antilock system

If any of these conditions exist, ABS may be inoperative, and the vehicle could lose the full protective capability of anti-lock braking in certain situations.

What to do if the ABS warning light comes on

Before taking action, understand that you are dealing with a braking safety system. The following steps help you assess and address the issue without risking your safety.

1. Safely reduce speed and, if possible, avoid hard or emergency braking until the issue is diagnosed.


2. Check the brake fluid level in the master cylinder reservoir and inspect for leaks or low levels. Do not let the fluid level get too low; if it is, top up with the correct DOT-rated brake fluid and look for the leak.


3. Check for other warning lights (Brake, traction/Stability Control) that might indicate related brake or sensor problems.


4. Inspect the wheel speed sensors and wiring at each wheel for obvious damage or disconnections. Clean or reseat connections if you can do so safely.


5. If you have a code reader, scan for ABS-related trouble codes to narrow down the faulty component (e.g., wheel speed sensor, ABS pump, or control module).


6. Have the system inspected by a qualified mechanic or Honda dealership. Persistent or repeating ABS light should be diagnosed and repaired promptly to restore ABS functionality.

Addressing ABS issues promptly helps ensure predictable braking performance and reduces the risk of losing steering control in an emergency.

Driving considerations and related indicators

If the ABS light is on, you can usually continue driving, but you should exercise caution, especially in wet or slippery conditions. If the light is accompanied by the Traction Control or Stability Control lights, the vehicle may limit some electronic aids until the problem is resolved. Do not delay a professional inspection if the light remains on or comes back after a reset.

Maintenance tips and prevention

Regular maintenance helps prevent ABS faults. Consider these practices as part of routine service for your Honda Accord:

• Have brake fluid checked and replaced at intervals recommended in your owner's manual; use the correct DOT specification.


• During brake service, inspect wheel speed sensors and related wiring for damage or corrosion.


• Ask technicians to read ABS codes during any brake system service to catch developing sensor or pump issues early.


• Keep tires with proper tread and even wear to avoid confusing wheel speed sensors and to maintain effective braking performance.

Routine diagnostics and timely repairs help ensure the ABS system functions when you need it most.

Summary

The ABS warning light on a Honda Accord signals a fault in the anti-lock braking system. While normal braking remains available, anti-lock braking may be compromised, which can affect steering control during hard braking. Common causes include faulty wheel speed sensors, ABS pump or control unit issues, low brake fluid, and electrical faults. If the light stays on, have the system diagnosed and repaired by a qualified technician promptly to restore full braking safety.

Bottom line

ABS issues are mechanical and electrical in nature, not just a single light to ignore. A diagnostic check, followed by any necessary component replacement, is essential for ensuring your Accord’s braking system retains its full safety capability.

Is it safe to drive with ABS warning light on?

If your ABS light comes on while you're driving, you can continue driving to your destination, as your normal brakes will still be working. However, we do recommend taking your car to a professional as soon as possible, as it can be dangerous to continue driving without a functioning ABS.

How much does it cost to fix ABS on a Honda Accord?

The average cost for a Honda Accord ABS Control Module Replacement is between $1,154 and $1,179. Labor costs are estimated between $53 and $78 while parts are typically priced around $1,101. This range does not include taxes and fees, and does not factor in your unique location.

Can I drive my Honda with the ABS light on?

While you can still drive your car with the ABS warning light on, it's not advisable to ignore the issue. Your vehicle's brakes may still work, but the risk of an accident increases without the ABS. Whether the problem is with the ABS module, a sensor, or low brake fluid, it's essential to address it promptly.

Why is my ABS light on in my Honda Accord?

An illuminated ABS light on a Honda Accord typically indicates a problem with the Anti-Lock Braking System, most commonly caused by a faulty wheel speed sensor, low brake fluid, or a malfunctioning ABS control module. Other potential issues include a blown fuse, damaged wiring, or a dirty sensor. A mechanic can diagnose the exact issue by reading the fault codes stored in the vehicle's system.

Common causes

• Wheel speed sensors: One or more sensors may be dirty, damaged, or have broken wiring. This is a very frequent cause of the light coming on. 
• Low brake fluid: A low brake fluid level can trigger the ABS light, and it's a good idea to check this first. 
• ABS control module: The module that controls the system could be faulty, which often requires replacement. 
• Blown fuse: A fuse related to the ABS system may have blown. 
• Wiring issues: Damaged or corroded wires connected to the sensors or module can cause a signal interruption. 
• Other issues: A faulty brake switch or hydraulic pump can also be the cause. 

What to do

1. Check brake fluid: The easiest thing to check first is the brake fluid level in the reservoir. 
2. Scan for codes: Have a mechanic or auto parts store scan the vehicle's ABS control module for diagnostic trouble codes to pinpoint the exact problem. 
3. Inspect sensors and wiring: If you are comfortable, check the wheel speed sensors and their wiring for any obvious damage or dirt, as cleaning them can sometimes resolve the issue. 
4. Seek professional diagnosis: If the problem is not obvious or simple to fix, it is best to have a qualified mechanic diagnose and repair the system, as a malfunctioning ABS system can affect braking performance and safety.
