The GIC218 cable features a compact, flexible design that fits seamlessly into the rear suspension bay. Its shielding protects against electromagnetic interference (EMI), ensuring accurate communication between the sensor and ECU. The cable’s connectors are engineered for secure attachment to both the sensor housing and the vehicle’s wiring harness.

Compatibility Overview

This cable is specifically tailored for vehicles equipped with the GIC218 brake pad wear indicator system. Common applications include:

• Land Rover Discovery III & IV (L319)
• Range Rover Sport L320 (various engine sizes: 2.7, 3.6, 4.4, 5.0)
• Discovery Mk3, Mk4 models
• Other Land Rover SUVs and vans that use the GIC218 architecture

For exact fitment, consult your vehicle’s service manual or a certified technician.

Installation Procedure

1. Disconnect Power: Safely disconnect the battery to prevent accidental electrical discharge.
