Stood in traffic this afternoon I noticed in the rear view mirror that all my park assist lights were illuminated, they then started flickering and went out, got to tescos and went to reverse into a parking space and noticed that the lights hadn't come on at all plus no beeps, the lights don't even light up when the ignition is turned on which they used to do. I know this might be one of those niggling little problems which sorts its self out overnight but any of you guys out there had anything similar ?

Might be worth checking to see if there is an associated fuse for it. Hopefully someone kind may have access to check the schematics.

The problem I had was somewhat different, used to get solid red light after a car wash but was OK when it dried out.

I now believe that problem was sorted after cleaning the sensors with a clay bar......lol It hasn't bleep after that, even during a heavy down pour or when its hosed down. Still keeping an eye on it though but its holding out well :yup:

Been looking through the handbook tonight and there's fuse 41 in the boot that serves the park assist, it also does the tpms and that seems to be working ok, wierd thing is i had a puncture in one of my tyres just before this happened, the garage repaired the flat but its got me thinking about the tpms, will deffo check the fuse in the morning though. I'm sure i've seen one of jacks posts showing the park assist module in the boot as well so i guess i'll be hunting that one down for any loose connections.

If its not working tomorrow, pull the correct fuse and plug back in. Hopefully its just one of them odd glitches, if there was a fault, it would throw up 'park assist' on the evic with a bong :yup:

 

[jackwalton]

Think it is on the same Can-bus communications loop as the TPMS module so it may just have got the comms hung up for some reason and systems may have stopped talking to each other. Prob worth while pulling fuse for a few minutes to see if it all starts up again as suggested above.

Yes gonna try the fuse pull this morning, hopefully that'll sort it, do you know whereabouts the park assist module is located jack?

Its within the rear quater panel vacinity, not too far from the car battery

Cheers mate, i guess thats my next step as the fuse pull didn't sort it.

If i remember right, can be disabled in EVIC.
May be worth while checking it hasnt disabled itself for some strange reason.
If isnt disabled you could try disabling it then take it on a short run while disabled, then enable it again ?
Only clutching at straws really, prob typical comms glitch.

Make a note of serial no while there, might be cheaper to try a replacement unit from a local Chrysler breakers. CANBUS is beyond my remit :yup:

yes I thought of that earlier on Jack and tried to disable it in the evic but it wont let me turn it off which seems strange.

 

[jackwalton]

Don't think we've heard of a Park Assist Module failing before ?
I would be tempted to pull fuse again, make sure the supply has gone off to module (Or unplug module itself) then run with the fuse out for quite a few hours (or minutes) then try it again.

I assume TPMS is working OK on EVIC ?

 

[jackwalton]

Just checked drawings and allsorts of other equip wired to same Canbus.

If pulling fuse for Park Assist Module for while doesnt fix it, I would personally disconnect battery for a few minutes and hope it sorts itself out.
If that doesnt fix it I would unplug all sensors from Park Assist Module and try with no sensors connected in case one is dragging system down for some reason. (Would then have to check if system can be enabled/disabled on EVIC) or plug sensors back in, one at a time.


EDIT
Bear in mind system will only enable itself when Reverse is selected. ( I know its obvious, but thought I'd better mention it) :lick:

Check all sensors for shorts to chassis while unplugged.
Codes may be stored but I assume a basic machine won't read them.

Thanks Jack, i'll have to try and get to the module next weekend, dont know what kind of job that will be!!, hopefully this week it will cure itself

Yes could easily sort itself out.
Play the waiting game. Lol. Not as though its critical.
Dont forget to try disconnecting battery before you start delving too deep though.

You may get back to us and say its sorted itself out.
Isn't technology wonderful.

Thanks for the reply jack, much appreciated, know what you mean about technology....its a proper pain when it goes south, i wouldn' t really want to go back to the old days but i could always fix my 1300cc ohv mk1 ford escort, everything was a doddle in them days, no canbus electronics to throw a wobbly !!. Regards disconnecting the battery my only concern is losing the radio as i haven't got the 4 digit pin to re input and to be honest i' d rather lose the sensors than my music.

May not need the code, but I know what you mean. Think its already registered and stored in the ECM and will automatically re-register itself. Think its only a problem if units are swapped between cars or new Radio fitted.

May be worth ringing Chrysler Customer Services to get the code anyway?
Will be on their system.

unless the radio has been changed and not registered any MAIN dealer can supply the code free of charge.
I lost mine when the battery was disconnected for a couple of days.
Rang the supplying dealer but as they are only franchised they couldnt help.
A call to the nearest main dealer got the code instantly with just the car reg number.

Thanks for the info, may try the battery disconnection if the park assist module connections look ok

Just checking if it has been sorted? Did you replace the module, check the wiring & sensors?
