The ABS warning light is not something you can simply erase without addressing an underlying fault. In most cases you should diagnose the issue with an ABS-capable OBD-II scanner, fix the problem, and clear the codes. If the fault remains or recurs, the light will come back and the braking system may be compromised.
The Honda Fit uses wheel-speed sensors and an ABS control module. When a fault is detected, the warning light illuminates to alert you to possible loss of anti-lock braking function. This guide explains how to read and clear ABS codes after repair, plus what to check if you don’t have diagnostic tools.
What the ABS light indicates on a Honda Fit
Understanding why the light is on helps determine whether you can reset it safely after repairs or if professional diagnosis is required. The ABS light may appear alone or alongside other indicators such as the Brake or Traction Control lights. A steady light usually means a fault; a blinking light can indicate a system fault during braking.
Common causes
Several issues commonly trigger the ABS warning in a Honda Fit. Checking these areas first can speed up diagnosis.
- Faulty wheel-speed sensor or damaged reluctor ring on a wheel
- Wiring damage or loose connectors at the wheel hubs
- Blown ABS fuse or faulty ABS relay
- Damage or failure in the ABS modulator/control module
Note: This list covers frequent culprits; the exact trouble codes from a scan will point to the specific circuit involved.
Resetting the ABS light with an ABS-capable OBD-II scanner
Before you start, ensure the underlying fault has been repaired. The following steps describe how to read and clear ABS codes after the repair so the warning can reset properly.
- Connect an ABS-capable OBD-II scan tool to the vehicle’s 16-pin data link connector (usually under the driver’s dash).
- Turn the ignition to ON with the engine OFF and power up the scanner.
- Navigate to the ABS/Brake system menu, read the stored codes, and note the fault(s) reported.
- Repair the underlying issue indicated by the codes (for example, replace a faulty wheel-speed sensor or repair wiring).
- Use the scanner to clear the ABS codes, then turn off the ignition and remove the scanner.
- Take the car for a cautious drive (5–10 miles) at moderate speeds to allow the ABS controller to reinitialize; the light should stay off if the fault is resolved.
Clearing the codes and reinitializing the system through a scan helps ensure the ABS warning is truly reset after the repair. If the light returns, the fault may still be present or recur.
What to do if you don’t have a diagnostic tool
Without an ABS scanner, you can perform basic checks that may address simple issues, but you cannot reliably erase ABS codes without clearing them in the controller.
- Check the ABS fuse(s) and related power circuits in the fuse box; replace any blown fuses.
- Inspect wheel-speed sensor wiring and connectors for corrosion, damage, or loose connections; reseat or clean as needed.
- Inspect the wheel-speed sensors themselves for dirt or damage; clean gently with a soft brush or electrical contact cleaner, taking care not to damage the sensor.
- Ensure the wheel hubs and tone rings are clean and free of debris that could affect the sensor reading.
These checks may fix simple sensor or wiring problems, but you’ll still need a scanner to clear the stored codes and reset the warning.
When to seek professional help
If the ABS light stays on after attempting a reset, or you notice braking irregularities (pulsing, grinding, or a soft pedal), have the system checked by a qualified technician. ABS is a safety-critical system, and a failure may require specialized tools and parts.
Summary
To reset the ABS light on a Honda Fit, diagnose the fault with an ABS-capable scanner and clear codes after the repair. Common culprits include wheel-speed sensors, wiring, and fuses. If you lack diagnostic tools, perform basic fuse and sensor checks, but rely on a scanner to erase stored codes. Always prioritize safety: if the light returns or braking feels off, seek professional service.
What is the most common cause of the ABS light to come on?
One of the most common reasons for an illuminated ABS warning light is a faulty wheel speed sensor. Speed sensors are usually located on the wheel hub or axle. They track how fast each wheel is spinning relative to the others, and send that data to an ABS control unit.
How do I reset the ABS light on my Honda?
And turn the ignition on once you have the ignition turned on the ABS. Light will come on and after it turns off remove your foot off the brake pedal the ABS.
Can I reset the ABS light myself?
Resetting the ABS light.
Disconnect the positive cable from your car battery, then let the electrical system's residual power drain by activating the headlight switch. This method can sometimes reset the ABS warning light. Or, use an OBD-II scanner to reset the ABS light.
Why is the ABS light showing on my Honda Fit?
ABS light. This can indicate a fault with the anti-lock brake system (ABS). Your car will still have regular brakes, but no anti-lock function, so take your vehicle to your local Honda service centre to find out what's happening.
