Rear Park Aid failure (2013 SHO PP)

[RichInMich]

Just started receiving the attached warning - intermittently - when going in reverse. Figured it was salt/snow mucking things up but just got a car wash and it continues to do it. Anyone else have this issue?

Get the codes read. That will more than likely point to the issue.

 

[RichInMich]

Going in Monday to do just that, will report back.

Just got it back, was a failed rear bumper parking aid harness (see attached). Appears to be fine once again. Also had the ambient light TSB applied to correct the ambient color switching back to stock.

 

[RichInMich]

Well, rear parking aid failed again shortly after I picked it up - looks like it'll be going back in to the shop...

If they cleaned up the harness properly, next step is likely to replace one or more sensors.

 

[jmr061]

Well those three listed codes are for sensor short to ground of the right rear outer, right rear inner and left rear outer parking sensors. Replacing the harness is the fix if it appears damaged or corroded. After that there is a bunch of OHMS testing and so on to locate the short.

Thanks guys - you rock. I'll let you know what I find out. Going to bring it in again next week.

Got it back - looks like it was corrosion on another harness, this time inside the front bumper cover... Here's hoping this repair holds lol

Isn't the THIRD time the charm? Gah.

That connector is in the rear bumper....typo on their behalf.

 

[jmr061]

BTW the harness they replaced the first time contains one half of that connector. Any logical person would have looked at the other half for corrosion when replacing it. Sounds to me like throwing the harness at it the first time was just a shot in the dark.

No wonder it stopped working

 

[RichInMich]

lol thanks guys for the morning laugh - after 2 days of use, appears to be working just fine so maybe a 3rd time's not going to be needed here! The system failed again within a day of getting it back the first time. Weird that they said front fascia twice on this RO, think they were trying to cover up the fact that they didn't make the proper repair the first time?

 

[SHOdded]

Wouldn't be the first time things are a** backwards.
