Product Information

Full details

This guide is for owners of RENAULT MEGANE I (BA0/1_) vehicles needing to replace their rear left ABS sensor. The key benefit is restoring proper Anti-lock Braking System (ABS) functionality and dashboard warning light deactivation. A potential caveat is that installation requires mechanical knowledge and proper tools. The Ci Ignition XABS853 is a passive wheel speed sensor designed for the rear axle's left side, featuring a 2-pin round connector and a total cable length of 540 mm, with an overall sensor length of 660 mm and a fitting depth of 50 mm.

FAQs

What does an ABS sensor do?

An ABS (Anti-lock Braking System) sensor monitors the rotational speed of each wheel. This information allows the vehicle's computer to detect if a wheel is locking up during braking and adjust brake pressure accordingly to maintain steering control.

How do I know if my rear left ABS sensor is faulty?

Common signs include the ABS warning light illuminating on the dashboard, a feeling that the brakes are not working effectively, or the ABS system activating when it shouldn't.

Is the Ci Ignition XABS853 a direct replacement part?

Yes, it is designed as a direct replacement for the original equipment manufacturer (OEM) part number RENAULT 7700834761 for compatible RENAULT MEGANE I models.

What is the difference between a passive and active ABS sensor?

Passive sensors generate their own voltage signal based on magnetic fields and wheel rotation. Active sensors require power from the vehicle and often provide a digital signal, potentially offering more precise readings in certain conditions.

Can I install this ABS sensor myself?

Installation requires basic automotive mechanical knowledge and tools. If you are not comfortable working on your vehicle's braking system, it is recommended to have a qualified mechanic perform the installation.

What is the overall length of the sensor?

The overall length of the Ci Ignition XABS853 sensor is 660 mm.

What is the cable length?

The cable length for this ABS sensor is 540 mm.

Troubleshooting

ABS warning light remains on after installation

Ensure the sensor is correctly seated and the connector is securely plugged in. Check the sensor wiring for damage. The issue might be with another ABS component (pump, module, or other sensors), or the new sensor may be faulty. Re-verify compatibility.

ABS system still not functioning correctly

Verify that the correct sensor was installed for the rear left position. Inspect the wiring harness for breaks or corrosion. A diagnostic scan tool may be needed to identify other potential issues within the ABS system.

Sensor connector is difficult to plug in

Ensure there is no dirt or debris in the connector ports. Do not force the connection; ensure alignment is correct before gently pushing them together.

Setup, Compatibility & Care

Compatibility:

This ABS sensor is specifically designed for the RENAULT MEGANE I (BA0/1_) with the 1.4 16V engine (BA0D, BA1H, BA0W, BA10) manufactured between March 1999 and August 2003. It is intended for Front-Wheel Drive models. Always verify your vehicle's original part number or consult a parts specialist to ensure compatibility before purchase.

Setup (Installation):

Installation typically involves the following steps:

  1. Safety First: Ensure the vehicle is parked on a level surface, the parking brake is engaged, and the engine is off. Allow brakes to cool if recently used.
  2. Access the Sensor: Locate the old ABS sensor on the rear left wheel hub assembly. This may require removing the wheel.
  3. Disconnect Wiring: Carefully unplug the electrical connector from the old sensor. Route the wiring harness to identify and disconnect it from any retaining clips.
  4. Remove Old Sensor: Unbolt or unclip the old sensor from its mounting point. It may be secured by a single bolt or a clip.
  5. Install New Sensor: Insert the Ci Ignition XABS853 into the mounting location, ensuring it sits flush. Secure it with the original bolt or clip.
  6. Connect Wiring: Reconnect the electrical connector to the new sensor. Route and secure the wiring harness, ensuring it is not stressed or near moving parts.
  7. Reassemble: If the wheel was removed, reinstall it and torque the lug nuts to specification.
  8. Test: Start the vehicle and check if the ABS warning light is off. Test the braking system gently in a safe area.

Care:

ABS sensors are sensitive components. Avoid exposing them to excessive force, harsh chemicals, or high-pressure washing directly. Keep the wiring and connector clean and free from corrosion. Regular visual inspection of the sensor and its wiring during maintenance can help prevent premature failure.
