VXR8 Indicator Rapid Flash - wierd fault

the ECU measures the resistance of the light circuit if it goes out of tolerance it will rapidly flash the indicator as a warning to the driver .

in cold weather the resistance would drop and set off the warning, the patch leads put a resistor between the feed to the light and neg(earth) its from memory about 360ohms i posted the exact resistance some time ago.

if you try the other lamp assuming the connections are the same and it does the same thing then there must be a wiring fault, you need to measure the wire resistances to see if there is any difference.

the soldering on these LEDs is a know problem , it may be worth checking the soldering and redoing any suspect joints if you can use a soldering iron. could save yourself a few hundred pounds!!

it does it with or without rear light and module connected so not sure what that means ??

the issue is because they changed from normal filament lamps to the led variety and the different characteristics cause the problem

swaping the light would prove if it is the light, if it works with another light(led cluster), id then check the resistance with the light connected and with it disconnected to see if the loom has gone to earth, assuming the front indicators are working.

without the light connected it will fault as it will be open circuit, it is looking for a specific resistance window,

Thanks all, swopped lamps and fault swopped sides so its the rear lamp ? i was confused that fault was still present when lamp disconnected, the fact that HSV swopped normal lamps for leds, the faults sort of make sense now

will the picador "fix" it or is worth taking the light apart and get electrician to sort poor soldering ?? how many have taken the lights apart

eek..... not quite sure what to do

[donk r8]

Sounds like a soldering job........... (sorry not helpful I know )

[preciousmetal]

I bet it isn't easy to get the lights apart, assume patience and a sharp knife to seperate the bonding ??? too much for me

I have found the upgraded wire looms if you want to give them a try, just in case..........

[preciousmetal]

Chris, might be the best bet first, thanks for the offer, please let me know when you are about as I am about tomorrow 9-3 at kingsley

[preciousmetal]

Thanks for all your help and especially to Chris (Donk r8) who popped over on Saturday. now resolved with 2 new mod. resistor Looms all working fine. now I understand more why they go wrong having looked at the wiring and set up

regards JB

Is there a way to cure this with a bit of work on the wiring?
I've got the yellow dot module but it didn't fix the fast flashing.

not sure what you mean about yellow dot module. I fitted a replacement flasher module and that didn't make any difference but the modified loom resistor fixed it

I think the yellow dot module is the modified loom resistor.

Hello all,

I have a couple of questions regarding the patch leads as I have got the same problem.

Picador sent me 2 leads ?

Is it one lead per side ?

Should both leads be fitted at the same time ?

Thanks

[preciousmetal]

One loom each side for each light, so one piar of looms does one pair of rear lights. the looms are not sides, the fit between main loom and rear module

Glad to hear Picador are still sending out looms, legends

FYI from now cars need to be checked by Picador for confirming fault on Tech2 before VX will release looms to dealer

If the fast flash only occurs on say the drivers side, ie both front and rear indicators, then I presume that the patch leads need to be installed on both the front and rear drivers side? Not just fitted to both rear lights, if the issue is only down the driver's side?

whatever side it is, fast flash will be on all 3 indicators per side ie front + rear lamps and side repeater. but the fault is only caused by rear lamp unit (LED) and that's the one that needs the loom

Guys, just installed two of indicator cables which were supplied free of charge from Picador in Southampton, the guy I dealt with is called:

Andy Kiloh
Service Manager
Picador Plc
02380 449232

Indicators all OK ;-)

The cables took about a month to arrive but no complaints as I said they cost nothing, must be carried out under a warranty.
Again I would like to thank Andy for his services.

That clears it up, cheers.

I have the fault on the driver's side and have the patch leads, as others have said I received 2xlooms and presumed as they appeared identical that one would be for the front and the other the rear...

[Demon Hill]

I got mine from Andy, I was initially told that the patch lead would be free, just pay for the postage, but I was charged £30 in the end ?

Never mind, at least the problem seems to be cured.
