How RH-5270 Works
The Arnott RH-5270 is a headlight level sensor / ride height sensor used in the rear suspension feedback circuit on Cadillac SRX and Cadillac STS models. It monitors suspension position and relays that information to the air suspension system, helping the system respond to changes in load and road conditions. This part cross-references OE part number 88957145 for the same application.
Common Problems This Sensor Can Address
- Suspension height readings that no longer match actual vehicle position
- Air suspension warning lights related to ride height feedback
- Uneven rear stance on Cadillac SRX or Cadillac STS models

- Sensor wear caused by exposure to water, salt, and road debris
Installation Notes
Verify rear left fitment before installation on 2004-2009 Cadillac SRX and 2005-2011 Cadillac STS applications. The sensor uses a single oval 3-pin female connector and a pin-style terminal layout. Mounting hardware is not included, so inspect the existing brackets and fasteners before service. Arnott recommends replacing sensors in pairs when servicing the suspension system.
