sisters car

2004 (04) plate Astra SRI 1.8; pretty sure its an immobilizer problem.

turn ignition on, the symbol of the car&spanner (yellow) continuously flash; nothing happens, doesnt even crank.

tried the spare key and the same problem; i think the key fobs have lost their code?

anything i can try and do?

cheers
matt

 

crank position sensor

 

ok according to autodata

system fault present

needs proggramming via diagnostics equipment mate

 

CPS wouldnt stop it from cranking over

 

i thought that might be the case; but i really dont want her to take it to "main stealers"!

as its immobilizer i think it will be the only option

the old vauxhalls you could reprogramme the key fobs by following a sequence but not sure you can do it on hers

 

Main dealers I'm afraid mate,they shouldn't charge much as it's only a 2minute job to program the transponders and immobiliser.

 

any ideas what it should cost?

 

But saying that I can't remember of the top of my head if that astra will require it but vauxhall bought out a software update for the cim module to stop it causing this fault.

Hth

 

cheers

 

No worries mate.if you were closer I could of sorted out for you mate.

 

thanks for the offer, appreciated

she'll have to go to Vauxhalls

 

try a garage using snap on diagnostics kit rather than main dealers mate might be worth a shot first

 

No worries mate.something to try tho to get it running if all it needs is the software update try turning the ignition on and of 6 times then try and start it in the 7th time if that makes sense.

 

but then it wont be able to reprogramme it?

 

Have you tried resetting ECU? Agreed immobiliser problem just seems strange it's lost both keys.

Martin

 

nope; how? is it the same ecu for the engine & immobilizer?

cheers

 

because it can access ecu functions and their is alot of info that can be accessed from a snap on diagnostics machine its basically the same machine that main dealers will use

 

to reset ecu disconnect battery for a period of time ( some are 30mins some take longer some overnight etc)

 

What he ^^ said. Although you just need to remove the KAM fuse on Fords, but just D/C the battery for 10 minutes as this is easiest.

Martin

 

easiest and safeist to d/c the battery

 

Not neccessarily as the fuse protects the memory so if removed no power so does the same thing and saves you D/C battery, make sure if you D/C you have relevant radio codes etc, if applicable on the car.

Martin

 

it wasn't a dig mate but seen so many people blow ecu removing & replacing fuse mate thats all

 

Oh no LOL diden't take it as one, just was saying, as you say the easiest way is to D/C battery.

Martin

 

If it is the cim then your looking at main dealer only anyhows as it'll need configuring (you'll need your security pass also mate)....most main dealers will discount the diagnostic cost from the repair costs also.

 

might sound stupid but have you tryed bump starting it?

 

+1 works on older clios! might be worth a shot
