Driver side rear sensors

[Thom.milburn]

Morning guys,

for the past few days my OE rear sensors have not been working, with just a solid tone when first engaging reverse.

I’ve listened to each sensor for the typical ‘ticking’ noise - both passenger side rear sensors appear to be working whilst neither driver side are.

Carista logs codes:

1079572
1079316

im presuming these are wired up in pairs where if one stops working the other in the pair does too?

figure a simple check would be to swap a known working sensor(s) in to those deemed at fault, obviously after cleaning connectors with contact cleaner first?

thanks all

No, all separately.

1079572 - Rear Right Parking Aid Sensor -- Open or Short to Ground​

1079316 - Center Rear Right Parking Aid Sensor -- Open or Short to Ground​

I'd guess a wiring/contact break - the sensors are not detected to be present at all.
