The ABS warning light coming on in a Honda Accord indicates there is a problem with the anti-lock braking system. While the car can still brake without ABS engaged, it is crucial to diagnose and repair the issue promptly for safety reasons.
I’ve been an ASE certified automotive technician for over 15 years and have seen my fair share of ABS light issues in Honda Accords. In this comprehensive guide, I’ll cover:
- What the ABS light means
- Common causes of the ABS light in Accords
- Is it safe to drive with the ABS light on
- How to reset the ABS light
Let’s dive in!
💡 Understanding The Honda Accord’s Abs System
Table of Content
The anti-lock braking system (ABS) in a Honda Accord helps prevent the wheels from locking up when hard or emergency braking is performed. This allows the driver to maintain steering control and avoid obstacles while braking heavily.
Here’s a quick overview of how it works:
- Each wheel has a wheel speed sensor that monitors how fast it is spinning
- This data is sent to the ABS computer module
- If the module detects a wheel is about to lock up while braking, it will rapidly pulse the brakes on and off for that wheel
- This prevents the wheel from fully locking up and maintains maneuverability
When operating correctly, ABS provides a tremendous safety benefit – especially in slippery conditions.
🚦 Common Causes Of The Abs Light In A Honda Accord
Based on my experience, here are the most common causes of the ABS light illuminating in a Honda Accord:
Faulty Wheel Speed Sensor
The wheel speed sensors are very vulnerable to damage from road debris, moisture, and general wear and tear. If one or more send inaccurate data or no data at all, the ABS module will turn on the warning light.
Troubleshooting: Scan for ABS codes to identify which of the four sensors may be faulty. Visually inspect wires and connectors for damage.
Low Brake Fluid
Over time, brake fluid level drops as the brake pads wear down. If it drops below the minimum, it can trigger the ABS light.
Troubleshooting: Top off brake fluid. Inspect brake pads/rotors for excessive wear. Check for leaks.
Cause 🚦 | Solution 💡 |
Faulty Wheel Speed Sensor | Scan codes & inspect sensors |
Low Brake Fluid | Top off fluid & check for leaks |
Bad ABS Pump/Module | Diagnose with codes, may need replacement |
Low Tire Pressure | Inflate tires & reset light |
Blown Fuse | Check and replace fuse |
Bad ABS Pump or Control Module
The ABS hydraulic control unit and electronic module can sporadically fail. This will turn on the warning light and require diagnosis.
Troubleshooting: Scan codes to confirm. May require rebuild or replacement.
Low Tire Pressure
If the air pressure drops significantly in one tire, it can confuse the ABS module and cause wheel speed sensor codes.
Troubleshooting: Inflate tires to proper PSI. Reset light.
Blown Fuse
Like any electrical system, a blown fuse interrupting power can deactivate the ABS and turn on the light.
Troubleshooting: Locate ABS fuse using manual. Test and replace if necessary.
Is It Safe To Drive With The Abs Light On?⚠
This is an important question when that dreaded ABS light pops up on your Honda’s dash. Here are the key things to consider:
- With the ABS system disabled, your brakes revert to normal operation without the pulsing action to prevent lock up
- Under most conditions, you can safely brake and steer normally
- However, during hard braking or slippery conditions, the risk of a lock up and loss of steering is increased
- The vehicle remains safe to drive cautiously for short distances
- Additional brake lights indicate a more serious issue requiring immediate repair
So in summary – the ABS light by itself means proceed with caution and limit hard braking inputs. But schedule service promptly to restore full braking capabilities.
How To Reset The Abs Light In A Honda Accord?🛠️
Resetting the pesky ABS warning light in a Honda Accord can be done in a few different ways:
Fix Underlying Issue
The proper way is to actually fix the underlying problem triggering the fault code. If it was caused by a bad sensor, leaking brake fluid, etc – addressing that will also make the light turn off once you drive a short distance.
Use an OBD2 Scanner
If you’ve fixed the mechanical issue but the light persists, connect an OBD2 scanner tool to access and clear any diagnostic trouble codes. This will reset the ABS control module and should turn off the dash light.
Disconnect Battery
Alternatively, you can reset the light by disconnecting the battery for 15 minutes which erases stored codes. This may allow it to turn off once resolved. But codes could return if not fully fixed.
The proper diagnostic and repair is best, but the battery reset can work in a pinch.
Frequently Asked Questions❓
Is It Ok To Drive With Abs And Brake Light On?
If the brake warning light is also on along with ABS – do not drive the vehicle and have it towed. This indicates a serious brake system issue beyond just disabled ABS.
How Much Is An ABS Control Module For A Honda Accord?
A genuine Honda ABS control module/unit can cost $500 on average. Aftermarket units are cheaper around $200-300 but may be less reliable. Rebuilds are sometimes an option as well.
Why Does My Honda Accord ABS And VSA Light Come On?
The VSA (Vehicle Stability Assist) system works integrated with the ABS module. So an ABS fault can also trigger the VSA light. Addressing the root ABS issue will also turn off VSA.
Can A Bad Wheel Bearing Cause ABS Light?
Yes, a severely worn wheel bearing that allows excessive wheel wobble can confuse the ABS sensors. But it’s not as common as electrical sensor faults.
Is It Safe To Use Cruise Control With ABS Light On?
Yes, you can continue using cruise control and normal driving functions with the ABS light on. Just use extra caution with hard braking inputs until the system is fixed.
Conclusion
Seeing your Honda Accord’s ABS warning light suddenly appear can give any driver a scare. While the implications may not indicate immediate danger, understanding what causes it to come on along with the appropriate response is critical.
The anti-lock brake system is a computer-controlled safety function, not just a single component. Issues from bad sensors to problems with central processors can disable it and turn on the yellow ABS light.
Diagnosing the root problem with OBDII code scans rather than guessing is key. Once identified and repaired, resetting any lingering warning lights with a system reset procedure should get you back on the road safely again.
