Service Park Assist Warning and Parking Sensor Replacement on Chevy Avalanche | Fix It Friday

[@MrAntonyperez]

And for anyone who don't have a code reader but wants to check if their sensors are working, just put your vehicle in reverse and turn the key to the start position (don't start the motor) and apply your parking brake then go and put your ear up against each sensor and if you hear a clicking or ticking noise the sensor is good and working

[@Revitauto]

I am going to try this!!!!! Thanks for the tip! Happy Motoring, Blair

[@cup_and_cone]

I did this... All four sensors are ticking. So either this isn't a valid method to determine if a sensor is actually dead, or there's a fault somewhere else.

[@MrAntonyperez]

@@cup_and_cone if all the sensors are emitting the ticking noise they are not dead but one or more maybe out of line. For example my truck had bumper damage near one of the sensors and had shifted out of position but was almost impossible to tell but after checking the wiring and clips that hold the sensor I found one ever so slightly angled and after adjusting it back to its correct position the park assist function worked perfectly again. Not sure if this will help you since you give no info of your systems issues

[@cup_and_cone]

@@MrAntonyperez My system is working again. My bumper was repainted years ago and when the shop did it they resprayed over the sensors. The paint started peeling from the sensors because of the rubber surrounds expanding and contracting over time. I carefully removed the respray paint from the sensors, while leaving the original factory paint, and now it's working fine. I'm wondering if the metallic in the paint maybe was interfering somehow. Also the 'service park assist' warning stayed on for a few starts after I did the fix, which threw me off thinking it wasn't fixed when it was.

[@MrAntonyperez]

@@cup_and_cone that's great news, yeah that was something I was going to ask in my last reply but forgot when I was explaining the issue I had lol. Those sensors are really pretty sensitive, it's not the metallic paint, even a little mud will throw them off every now and again.

[@JasonfromMinnesota]

Is there any other ways to reset it after your place of that sensor?

[@Polish_Hammer1987]

I've got a trailer hitch so every time I reverse I hear a solid tone. Which sucks when I'm on a call because it turns down the volume of the call super low.

[@tangerine5781]

This fixed my sensor issue. Hitch was too big. Removed it, no error message.

[@gregcy89]

Thanks man. Good idea. My Jaguar front bumper was removed to be painted and now the whole parking assist is disabled. Maybe if i just clear the issue with a diagnostic tool it will work again

[@Revitauto]

There are a few things that need to be checked, did they paint over the new sensors? Are they plugged in correctly? What codes are you getting? For all sensors or just one? Are you getting codes or does it just constantly beep!

[@gregcy89]

@@Revitauto with a diagnostic tool i get 4 errors on the parking sensors. 3 show offline and 1 looks online(3 look grey on the diagnostic screen and shows blue). I hope they are just not connected properly coz they were working fine before and after the bumper was scratched

What causes no sound mine work just no sound anymore they worked before now my blinkers don’t make sound when turning either it’s silent

[@Revitauto]

Hmmmm I will have to do some research. Can you check the Driver settings make sure you dont have it turned off ?

[@SweetestGapeach1127]

That’s exactly what mine doing. I had a car cover on & when I got back the weather took it off.. now my Park assistant is off & no sounds

[@darrylroberts961]

Did u ever find out what that problem was. The no ticking sound and no blinker sound?

i got a 2015 cadillac srx Luxury I replace all new parking sensors in the front bumper and all new wiring harness still my parking assist sensor doesn't work I got the message they don't work the backs ones work just fine where is the fuse for the parking sensors at in my cadillac srx

[@stephengoss5895]

I have this scan tool!!! Md 808 pro! I don’t have check engine light on at all no codes....but I do have service park assist on. How did u clear these messages with this tool with no check engine light on?

[@Revitauto]

Hey Stephen, after I repaired the failed sensor the code went away. I also did an all module scan and erase. There was a guy who commented on here earlier @antony perez "And for anyone who don't have a code reader but wants to check if their sensors are working, just put your vehicle in reverse and turn the key to the start position (don't start the motor) and apply your parking brake then go and put your ear up against each sensor and if you hear a clicking or ticking noise the sensor is good and working " Seems like good details. Be sure to use wheel chocks be on a flat surface and for extra safety have someone in the truck who can press the brake pedal if need be! Happy Motoring, Blair

[@alexmcgovern2983]

if you have service park assist message with no current codes it means there is no communication with the park assist module, - GM technician,.

[@pomz3604]

The service warning disappears once all sensors are firing. Turn key to on, don't start the engine! Put it in reverse, (chock wheels first) using a stethoscope or the sound recorder on your phone, press against each sensor. You should hear tick-tick-tick at each sensor. If one doesn't tick try swapping sensors to confirm if bad sensor or bad wiring to sensor. Mine was just a bad connection at one sensor. I cleaned the pins and all good!

I have a problem with the park assist blocked message. It came on as soon as I installed a large tow hitch. I removed but the warning light will not go out

[@Revitauto]

Interesting yes we have the same issue when we put on a larger tow hitch But it never stayed on after a few drive cycles. Did yours eventually go out?

[@jasontindal2525]

@@Revitauto it did ty, after a couple cycles.

[@22prettywoman]

I was having same issue Thank u for ur comment post hope mine removes in couple of days

[@cup_and_cone]

The vehicle assumes you have a trailer connected so will disable park assist next time you start it. It will take some drive cycles for it go out.

[@NewVisionLCS]

Thanks to your video I'm going to recheck system. I have an 07 Avalanche and I replaced all the sensors and still get service parking assist. Strange thing is, when I connect our trailer it will beep first, then pop up service parking assist. Also, am I checking for 8v at blue wire of each sensor?

[@AntoineFinch]

i put a telsa style radio in my suburban today now this warnibg is on, could i have done something wrong in the install that could of caused this?

2013 Suburban. Sensor 3 & 4 don't work. It's not the sensors themselves as I can swap them for 1 & 2 location where they work. I just changed the harness, same issue. Stumped. Help ... anyone ?

[@seanvarga3932]

Do the codes have to be cleared after the new sensors have been installed? The service park assist message is still on after harness and sensor replacement. Thanks

[@Revitauto]

I erased the code however on another vehicle, after I cycled the key it worked without erasing the code. What code did you have on your vehicle?

[@seanvarga3932]

@@RevitautoI dont have a good enough scan tool to read the codes from the parking sensors. I have a 2007 chevy 1500 and I replaced the harness and all 4 sensors. The sensors work but after i drive the truck the service parking assist still apears on the dash.

[@domy2yo]

what type of sensor did you put?.. vehicle is very sensitive to aftermarket sensor

[@Revitauto]

Thanks for sharing Neil, can you tell us more about your experience with aftermarket sensors?

[@Revitauto]

Sean would be awesome to get a scanner on your car to see exactly what code you are getting, make sure its a sensor problem in the first place. Oddly enough on our Sierra we would get that error message if just a ball and hitch was installed in the receiver.

[@112188Francisco]

mine doesn't say service park assist. they just stay off and i cant turn them on? could it be because i replaced the stock radio unit? help 09 sierra Denali

[@Revitauto]

Without seeing your car I wouldnt be able to give you a clear answer. Have you checked fuses? Vehicle settings? Did they ever work?

[@remogalaz9744]

Mine is doing the same thing after I had the evaporator case replaced

I believe if you have a large hitch in it wont work sometimes. If you have a hitch in take it out and try it

[@112188Francisco]

Blake Cottrell i tried that but its not the problem. I switched out the stock radio unit for an aftermarket one... could that be the problem?
