Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Existing Sensor: Unscrew the old sensor housing and gently detach the sensor from the wheel hub. Note the orientation for correct reinstallation.
3. Prepare the New Sensor: Align the GBS2040 with the mounting flange, ensuring that the sensor’s magnetic field aligns precisely with the wheel’s rotating elements.
4. Secure the Housing: Tighten the mounting bolts to the manufacturer’s specified torque (typically 20–25 Nm). Use a calibrated torque wrench for accuracy.
5. Reconnect Wiring: Plug the sensor connector into the vehicle’s harness, verifying correct pin alignment. Inspect for any bent pins or damaged insulation.
6. Test Functionality: Reconnect the battery and start the engine. Use a diagnostic scan tool to confirm that wheel speed data is being transmitted correctly to the ABS control module.
