Service Park Assist when I hit the brakes

[Phil347]

THANK YOU !!!!
I ordered it and it is on the way

I received the Autel AP200 about 2 weeks ago. took over a week through their "Support" to get it to just "Register",
turns out it had been returned by someone else and these are one vehicle use only so I could not get it to pair up with mine
( You would have to buy a separate software download for every vehicle you use it on).
They finally had reset it from their end in China. Once I got it up and running I saw tons of data codes and stats but "No Codes Found"
( While the SERVICE PARK ASSIST was on my dash display ).
I tried Tech support and sent in the Log for assistance- 3 days have passed No response and no change, so I returned the unit.

Sorry to hear about the hassle, I guess Amazon sold you a used unit. I bought mine at Walmart, had no trouble setting up and works great. Oh well.

BTW, you don't have to buy separate software for each vehicle. Only for each auto manufacturer. For instance, I have GM which works on all GM vehicles, I can (and have) use(d) in other GM vehicles with my same odbII dongle and my phone with the software installed.

I went to a garage and got back a report:

Engine
P0174 Fuel Trim System Lean Bank 2
Anti lock Brakes
C0561 System Disabled Information Stored Invalid Serial Data Received ( Symptom 71)
U0101 Lost Communication With Transmission Control System ( Symptom 00)
U0073 Control Module Communication Bus Off ( Symptom 00)
Parking Assist Module
B0959 Parking Aid Rear Sensor 2 Circuit Short to Battery ( Symptom 01)
B0960 Parking Aid Rear Sensor 3 Circuit Short to Battery ( Symptom 01)
Rollover Sensor
B1011 System Disabled Information Stored Invalid Serial Data Received ( Symptom 71)
Transfer Case
U0101Lost Communication with TCM (Symptom 00)
Vehicle Communication Interface
B1000 Electronic Control Unit (Symptom 00)

ALSO:
My Mechanic suggested installing extra Ground leads to Frame and Firewall, I did this but no change
(As I previously mentioned I have replaced all 4 park assist sensors and the rear wiring harness that feeds them)

All those lost communication codes for all those different components leads me to believe you may have a control module issue or some grounding issues, or a harness that is worn through somewhere with wire grounding out or touching other worn wires.

Have you completely disconnected your battery for an hour or more to allow the systems to clear? If not, maybe give that a shot.

Yes, I disconnected the battery and hooked up supplementary #6 grounds from main ground at engine to Frame and Firewall.
I have removed, cleaned and reattached every Ground I could find from front to back. ( all appeared good even before I cleaned them up)
I "tried" to follow every wire harness looking for physical damage ( None found)
I am thinking about just changing entire wiring harnesses as I am stumped at the moment

I'm not certain, but if all the items that are throwing the errors ultimately run through the same one control module (I think there are 3 or 4) then maybe that is the culprit. Maybe a little research is in order. When I can, I'll see if the service manual specifies which one or ones.

OK, The long drawn out saga has finally ended.
After spending over $2,000 at the local GM dealer, I had given up and just drove with the fault, Until I started getting a Service Engine light and various other alarms when ever I sat at idle too long, so it had to looked at AGAIN!

I found a different GM dealer who has a Electronic Specialist on staff.
This guy understood the problems almost immediately and agreed with everything I was suggesting (with the help of this Forum)

Took him just 2 hours to find:
2 of the MADE IN China After Market rear Bumper object Sensors ( JDMON X002J2QJS5) were had different readings,
and were reading 300 Milli volts lower than the others
Replaced with Dealer supplied factory sensors, and that solved the issue!
He said almost all of the other GM repairs, parts and wiring harness were a waste and should never had been needed and could easily have been proven out.

So to recap: Service Park Assist message while driving was caused by 2 rear bumper object sensors
I had replaced them with after market and then spent over $3,000 only to discover, they were bad as well

The Service Engine at idle issue was unrelated as a Vacuum line for the PVC sensor had split causing a totally separate problem which was easily solved,
I only include this in the story as it was encouraged me to seek repair again)

Thanks for everyone's suggestions along the way

Hi Mate,

Can you please give me the part number and where did you order the aftermarket parts ?

Thanks

2 of the MADE IN China After Market rear Bumper object Sensors ( JDMON X002J2QJS5)
I got them off Amazon, ( I can't remember the actual sellers name)

They look exactly the same and they do work as sensors, they just give a different feedback voltage which causes the errors
