I have a constant noise when the sensors are enabled (Switch on left rear quarter panel) I have replaced the sensors still get the same error noise. Can anyone help me wihth the location of the control unit. This is for a Gen 1 RDX 2011. Thanks for the assist.

 

I believe this was only available as a dealer-installed option and not part of any factory package, which is to say probably very few people actually have this on their first gen RDX. It may also not be in the FSM, but maybe someone with a copy of the 2011 version can confirm. Best of luck on this one.

 

The wiring to the sensors in the rear bumper appear to be part of the master wiring harness. This vehicle has the tech package with upgraded entertainment system so I'm thinking it was included in that package but I could be wrong. If anyone has the service manual please do let me know.
