Why Choose This Part
Designed as an OEM-style harness, the assembly reduces installation time compared with fitting individual sensors and wiring separately. It is especially useful when replacing a damaged rear harness after bumper removal or impact. Supplying complete pre-wired sensors and illumination simplifies diagnostics and ensures correct sensor spacing for the 307 CC rear bumper.
Installation Recommendations
- Disconnect the negative battery terminal before any electrical work to avoid short circuits or ECU faults.
- Carefully remove the rear bumper or inner trim to access sensor mounting points and existing connectors.
- Unplug the original harness from factory connectors and remove old sensors. Fit the new harness sensors into the bumper holes, ensuring correct orientation and secure seating.
- Route and fasten the loom along the original clip points to avoid chafing; secure connectors with dielectric grease to reduce corrosion risk.
- Reconnect the harness to the vehicle connector and license plate lamp, reassemble the trim/bumpers, reconnect the battery and perform a functional check of the PDC system.
Most Common Failure Reasons
- Water Ingress: Moisture in sensor housings or connector plugs causes intermittent operation or complete failure.
- Impact Damage: Bumper hits or minor collisions often damage sensors or the harness routing, breaking connectors or wires.
- Corrosion And Oxidation: Poor sealing at connector interfaces leads to corrosion, especially in regions with road salt.
- Mechanical Wear: Abrasion from improper routing or pinched cables during repairs can cut conductors.
