Installation Guidelines

1. Preparation: Disconnect the vehicle’s battery to prevent electrical shock or inadvertent activation of safety systems.
2. Removal of Old Sensor: Unscrew the existing wheel speed sensor using a suitable socket set. Carefully detach any wiring harnesses, noting connector orientation.
3. Mounting the GBS2081: Align the new sensor’s mounting flange with the vehicle’s wheel hub. Secure it with the provided bolts and torque specifications (typically 20–25 Nm).
4. Wiring: Connect the sensor to the ABS/ESP control unit using the original harness or a compatible adapter. Ensure connectors are fully seated and insulated.
5. Testing: Reconnect the battery, start the engine, and verify that the ABS indicator lights up correctly. Perform a brief drive test to confirm proper wheel speed detection.

Maintenance Tips

• Inspect sensor wiring for wear or damage during routine maintenance checks.
• Avoid exposing the sensor to excessive moisture; use protective coatings if operating in harsh environments.
• Replace the sensor promptly if ABS/ESP warning lights remain illuminated after a drive cycle.
