Please HELP, My G Voager Has gone nuts.


Symptoms

Gearbox sometimes works ok sometimes wont go past 2nd gear.
Tail/HeadLights stay on after ignition off
Dash lights stay on after ignition off
Radio/Nav Unit stays on after ignition off
Windscreen Wipers dont work
Fuel Gauge is Dead and the OHD shows there is 0 range (theres fuelin the car)
SnapOn Scanner said it was the speed input sensor. but why would all the other electrics gone mad.
Elec. Doors and Tail Gate only works once you first plug the battery in then they stop working.
RH Side Mirror Folds out too far.



Checked

The Battery fully recharged, tried 3 types, incl GEL Optima Red Top same issues.
Alternator charging perfectly.
Engine and Turbo are spot on, pulls like a train.
Gearbox gear changes are smooth no sharp jerks.


Other Electrics All works


HEEEEELLLLLLPPPPP PPPPPLLLLLLLEEEEEAAAAAAASSSSSSEEEEE!

 

Yes, It's going nuts...But Engine and Gearbox working as they should...Interesting...
What's codes and your car info..Its obviously rebooted..Maybe looksee at contacts underside of fuse box..Big rightup on her about this box and its contacts..
Think you'll hear more about this...

 

Thanks for your reply, I shall check the connectionsand earthing as that seems to be mentioned a lot.
The gearbox is gone bad too, most of the time wont switch upwards of 2 but then it works fine sometimes. Im stumped, really really hope its dodgy connections.

 

What you can do and what you must pay others to do for you. You can do the basics of 'wiggle tests', green verde contacts, and high ohms of resistance.

IPM [TIPM] or earths' [ground circuits] are both good bets for a solution. It would be nice if we knew what year it was. A ground circuit is a very bad tempered mistress it will always fight to make its way back home - to the negative battery terminal, if its path is blocked that component with create havoc, even the negative battery cable itself can be a good supect fro replacement. Likewise 3 computers run the car, each is routed through the IPM, the contacts if corroded in the multi layer IPM [signal - voltage - grounds] will also create the kind of multiple havoc you have described in #1.

 

My money is on the battery grounding circuit -- all of it. Be sure the battery post connectors are bright-metal clean too.

Just wanted to add, I did the keydance and I get P1652.
Is that a short somewhere?

 

1652 is a communications bus error.

Somewhere there is a fault on the bus wiring or there is a module that is affecting the bus. Bus wiring drawings can be found here
