VXR8 Indicator Rapid Flash - wierd fault
Discussion
2007 VXR8 has indicator rapid flash fault. not sure its the usual fault as its only on LH side
have tried another working rear light - still faulty
replaced rear light module - still faulty
indicators flash 3 times normal speed on lane change okay
indicate left, flash normal 3 times (lane change) then rapid flash starts and continues
if you disconnect rear lamp, still does the same fault so not rear light (I think)
possible flasher relay or BCM ??

Sorry you need a new light have tried another working rear light - still faulty

Had the same thing like a lot of us
Sorry for the old questions. As never actually seen it happen before. As that's what I thought - the light -
so even disconnecting rear light. Still does rapid flash ?
Also when rapid flashing happens does it always inducate okay for 3 flashes then goes rapid ?
Is this the normal fault regards rapid flashing fault
Thx

There is a cable that can fix the rapid flash fault but it didn't work for me. If you think its a fault with the light unit you can take the one out from the other side and try it with that the connector is the same. If the problem goes away then there is a light unit problem. In the end I fixed mine by taking the light unit apart and tidying up some of the soldering. If you can solder then honestly the hardest part of this is getting the back off the light unit to begin with as its sealed on.

I beleive the fault is down to how much current (amps) is being drawn by the light unit James from what I've read..
Picadors did the patch leads.ARAF said:

Picadors did the patch leads.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 ??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.

Found these James, They may help... Regards Paul

Turn Signal Has High Flash Rate
Vehicles:
VXR8 – All Models
Condition:
One or both turn signals flash at approximately double normal flash rate. Condition is normally
experienced under low temperature conditions, and flash rate may return to normal when
ambient or in - vehicle temperatures increase.
Cause:
Turn signal outage detection module specification may cause high flash rate under low
temperature conditions.
Correction – Vehicle Production.
Specification of the module has been revised effective from vehicles built July 7, 2008
Correction – Vehicles In Service
Replace turn signal module, for the affected turn signal only with later part available from
normal service parts outlet. Part number has not been revised. All service parts stock has been
culled and only revised modules are available from service parts warehouse and distributors.
Revised parts are indicated by a yellow sticker on the module housing.
Note
Due to wiring revisions which are not related to this issue, specification of the turn signal lamp
and module was revised effective at breakpoints indicated below. Modules are not
interchangeable between vehicles built before and after this breakpoint, Vehicles built both
prior to and after this VIN breakpoint may experience the high flash rate condition, and
specification of both part numbers has been updated to prevent this condition.
