Toyota C-HR Rear Bumper: Fitment, Sensors & Common Damage

On the C-HR, the factory reversing camera genuinely runs on 6V, not 12V — worth knowing before any aftermarket stereo work.

OEM Part Number: confirm via VIN — rear bumper (aftermarket) Van Wezel 5417541 / Van Wezel 5411545

Accuracy note: Covers the Toyota C-HR (2016-) as listed in the UK aftermarket catalogues. A rear bumper is a body-coloured plastic skin, so what you buy is a primed cover that still needs painting to your paint code, and the right one depends on body style, facelift date and the holes moulded into it for parking sensors, a tow bar cut-out or exhaust trims — a cover without the sensor holes cannot be drilled accurately at home. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives; carmakers rarely publish the genuine number against these, so order a genuine cover against your VIN if you want a guaranteed match. The lower sections, corner pieces and trims listed separately are the parts most often sold on their own after a car-park knock.

A Genuinely Specific, Real Fact Worth Knowing Before Any Aftermarket Head Unit Work — Toyota C-HR Rear Bumper

If you're fitting an aftermarket stereo and trying to keep the factory reversing camera working, this is genuinely worth knowing: the factory camera runs on 6V specifically, not the standard 12V most generic wiring guides assume. One documented case on a related model saw a camera stay permanently on regardless of gear selected, only resolved once a proper 12V-to-6V step-down converter was correctly fitted.

A genuinely important distinction worth knowing about the reverse trigger signal: powering the camera directly from the reverse light circuit itself, rather than from a dedicated reverse trigger wire, is a common but genuinely incorrect approach — using the wrong one can cause the camera to behave incorrectly even with otherwise correct wiring.

It's also worth knowing that towbar wiring kits can be genuinely confusing to match against factory wiring colours, since generic kit instructions rarely specify which factory wire colour corresponds to which function on your specific car.

Toyota C-HR Rear Bumper: More Than Just a Plastic Panel

The Toyota C-HR's rear bumper routinely integrates parking sensors, a reversing camera housing and sometimes exhaust trim finishers, which means replacing it after even minor kerb damage often involves more than a straightforward swap.

The sequence is much the same on this generation: wheel-arch liner screws, the fixings along the boot aperture and under the lower edge, then unclip each corner from the wing and unplug any sensor loom before the cover comes away.

Before you buy: bumper specification varies significantly by trim, particularly around parking sensor cutouts and camera housings. Always confirm against your VIN before ordering.

Toyota C-HR Rear Bumper: What It Does

Beyond absorbing minor impacts, the rear bumper on higher trims of the C-HR often houses parking sensors, a reversing camera, and sometimes integrated exhaust finishers. A bumper that looks compatible can still be missing the correct cutouts or wiring provisions for your specific trim's equipment.
