srs fault

[dagar187]

hey ppl,was just wandering if someone could tell me how to reset the comp as my mate left the ignition on ácc' over nite(driveways in backyard) and drained the baterry.is the airbag warning fault mean somethings stuffed or can we just turn it off like the service reminders? also having a flat battery does that reset everything?as in the settings i chose egpd depndnt etc.

From what I have read in other posts, I think you need to take it to Holden to reset the air bag light. Just resetting the ECU won't do it.

damn! oh well its gonna have to go in for its reg serv anyway just wanted to find out if it culd be fixed now as its a bit annoying.cheers abba.

I had all sort of warnings (including the SRS warning) when the negative earth came loose.

After tightening the battery earth it started fine and the warnings went away. Try resetting the ECU and the warnings may go away.

yeah might as well give it a go wont hurt.thanx

I've done that twice left the key on Acc and in the morning the battery was dead not even a click. Just put jumper leads on started it and away it went did not affect any settings made by me.
Best to turn that feature off I think it's called "open door turns everything off " but it does not work if you leave the key on ACC.

tried resetting the ecu.no luck,still bloody there.oh well just have to wait till service(nxt wk).ronald did yours have this reluctance in the accelerator pedal after starting her again? after jump strting mine i put her into drive and nothing was happening,pedal just depressed like it was(car)off.then turned her bak off then on this time put into reverse and same thing again.third go i gave the pedal a real quick jab and finally got moving.is this wierd sht or is it normal?

When the battery has been disconnected or run flat it will need to relearn the idle. To do this, have vehicle in park, start, from park move shifter to each gear for 10 seconds, put back into park, remembering of course to have your foot on the brake. Turn off, start engine again, rev to 2000rpm for 10 seconds, turn off. This should reset your idle.

I think it's weird that running the battery flat would bring up your "SRS Fault" light. That normally happens if you disconnect your airbag wires or fuse and then turn on the ignition. Was this the case? E.g. did you take the front seat out and disconnect the wires or something? :confused

Anyway, yeah you'll need to get it reset by a dealer. If you're doing a service at the same time, they shouldn't charge you for it, since it is literally a 2 minute job. They tried to charge me $70 for the priveledge, but then they waived the fee after I had a whinge.

The SRS system has a capacitor so that if you are involved in a crash that cuts the power from the battery the airbags and seat belt pre tensioners still go off. If the battery power was insufficient for an extended period, say more than 10 minutes, then the capacitors drain and your SRS fault will light up next time you power up the vehicle. To stop that from happening, remove the SRS fuse if the car is to be without power for a while then refit it before the ignition is turned on.

I changed the battery in my car a couple of weeks ago. While doing so, my battery was disconnected for much longer than 10 minutes. How come my SRS light didn't come on then?

[Not_An_Abba_Fan]

I don't know. Maybe it is longer than 10 mins I just said that time as an example maybe it's 2 hours I don't know. From what I have read in other threads, it seems that when someone has had a battery problem it triggers the SRS fault light. I could be wrong. It also may have had something to do with the fact that the key being left on acc drained the battery, wouldn't that be the same as having no power to the SRS with the ignition on?

the srs will have a code in it for system voltage low
resetting the engine controller will have no effect on the srs, its a different module.
the VZ doesnt need to rev to relearn the idle, if you turn the ignition on & not start it for 30 seconds you will hear the throttle operate, this is the reset.
if you drive it it will set itself anyway.

Good point...

Fitting extractors to cars with an ECU most of them need to be reset because of disconnecting the battery.

Thanks Rob, didn't know the VZ was like that.
