Central Locking Dead And Obd Port Dead

[bertiee]

hiya chaps, wonder if anyone can help me with a few issues on my new purchase.

 

W reg MK1 TD galaxy, just bought it a week ago, so far nice driver and worth the money. 4th Galaxy I've owned and it's the 1st diesel the others were petrol.

 

The central locking is completely dead, no power to doors before trunking in doors, red wire with white tracer is live from fuse 19 from fusebox and goes skywards towards bulkhead, so can't test anymore, all other fuses are OK and none missing, electric windows and mirrors work.

 

The OBD port should also carry this wire but it's dead at the pin on the port?

 

I've ran a positive to the port and can get it to work, diagnosed I've got a dodgy ABS sensor front left.

 

The fusebox is a triple deck job, nothing under passenger seat, no other fusebox in engine bay. Nothing under passenger dashboard.

 

It;s got me stumped.

 

thanks

 

Simon

have you tried fuse box under drivers seat ?.BRY

Yes I looked under both seats but there are no boxes

I've taken the passenger side trim off to check wiring but all looks good

 

I ran a live to the obd port red/ white wire and this powered up the port so my reader could read faults. Left side ABS sensor fault !!!

 

From what I can see the red/white tracer wire is live from fuse box but goes up into bulkhead where it disappears the same coloured wire is dead at both door harnessed before the door gaitors ie behind kick plates

I've had clocks out but can't see where wire goes :-(

Hi there

You said you had the n/s floor trim removed iirc there's a bunch of them red/white wires there by the side of seat, other members have found these wires just twisted together and just needed soldering, they had got corroded from a probable wet footwell.

Can confirm fuse 19 does cover the diagnostic socket aswell so when you find the fault it will probably fix both

This is a w reg diesel

Should there be an aux fusebox?

I've searched under bonnet and behind glovebox but nowt

The red/white wire is dead along passenger kick panel and along the cill plate

 

It'll not defeat me !!! Might just take some time

 

Thanks to those members who have helped, please keep yr suggestions coming as gratefully recieved

Hi

The Mk1 doesn't have the extra fuse box but check the positive battery terminal there are a number of smaller wires attached make sure non have broken off or corroded,

also that fuse 19 did you check it for power also with the fuse in place, any high resistance on that circuit and the voltage would drop to zero when it has a load on it, with the fuse removed it could show 12 volts put the fuse back in drops to nothing, worth a try.

just a quick update

 

I've been buying a Sealey PPX test probe ( great piece of kit ) and it allows me to power up the fusebox with a postive or negative charge.

Anyway, I tried the fuses 19, 55 and tried with new fuses, powered them up in situ but nowt at C/L or OBD port.

But

when I probed the left side of fusebox, I was getting a Neg reading at the fuses not a Postive.

I whipped out my multimeter and confirmed the neg at the fuses roughly 1-5

 

This now makes me think the fusebox is faulty

 

Anyone come across this?

 

All other electrics work on car, just C/L & OBD port dead. Tho if I power up the red/white wire at back of OBD it works a treat, even allowed me to erase the ABS sensor fault.

 

 

thanks

Hi Simon,

sounds like you have lots of red herrings going on. I would go back to all doors and tail gate and double check wires haven't twisted together or cracked causing a short to ground .
