engine light /service now light
what pins do have to sort out to get the flash codes to come up
and what are the numbers for the codes
got to flash mine see why the light comes on and loses power

Re: engine light /service now light
top right, and the one next to it (on the top line)
connect jump wire between these terminals, then turn ignition on (dont start)
it will flash code 12 first (to show its working) then the code
there are 35 codes, (will put them up on tech section one day)
let me know what code(s) come up and I will look it up

Re: engine light /service now light
bigger problems now just went to go to my uncles to do some work jumped in first time its been started today as i left it at work last night and it would not start/run gave it a bit of gas and it will run as soon as you take it off it s stalls now i have it idling but is very low
the ses light is on and now the rad fan is running all the time and not the one i have wired in does not have any pwer to speak of would be able to drive but not fast
tryed to do the codes put my pin in and the light does not flash have voltage to the pins and a earth (5v to pn b and earth to pin a )
any one know
and any one know were the ecu is so i canmake sure the plugs are good
going to have a quick look tonight see if i can see anything then will give up and look and post on 3rdgen have just been looking but cant find anything

Re: engine light /service now light
some good news disconected the battery and found the ecu took that off gave it a clean all back together light is now off and the fan plus got the flash codes up and flash 12 so all good there
did read on 3rdgen that some took there ecu's off gave it a clean and has been ok since
will find out tomorrow as i have a few miles to do

Re: engine light /service now light
well light come on again this morning just flashed it and has come up with code 42
42. Fault at electronic spark timing circuit OR Fault at direct ignition system OR Fault at fuel cutoff relay circuit
any one had this before and what was it need somewere to start lookiing

Re: engine light /service now light
I'm not techy on this really but I'd check that all of the injector connections are fine and then do a timing test or something. That should rule out two of the possibilities!

Re: engine light /service now light
well i have had the battery off most of teh day and has cleared and seems to be running ok am going to do a test and not run it so low on petrol next week end see if it comes on as it only seems to happen at a weekend lol

Re: engine light /service now light
code 42 is electronic spark timing
if it is only coming on intermitently, according to the w/shop manual, it can be caused by a loose mem.cal, or one not fully seated in the ECM
worth checking

Re: engine light /service now light
the mem-cal is the "chip" inside the ECM
it is under the plate screwed on the side of the ECM

Re: engine light /service now light
the ses light came on yesterday and the car was running really bad. turned it off and left it for an hour and has been fine since.....
Re: engine light /service now light
do you know how to read the codes?
(put a bit of wire between the top right terminal and the terminal next to it, of the diagnostic plug) under the dash to the left of the steering column
then count the flashes of the SES light

Re: engine light /service now light
was it running bad at idle but ok ish when driving as i had that at the last checkers i went to in it
the plug is behind the fan switch by your right foot
and the 2 black wire behind that are the rear fog light
but when the light come on for me left it for a while and was ok

i'll check it tomorrow. what do i use to bridge the terminals coz i dont wanna go and use something like a paper clip and blow myself up or something silly like that. me and electrics mix like oil and water

:yup:SUPERCHARGEDGTA wrote:paper clip will work fine
its only 12 volts
Just remember to take it out when your done lol. I've left mine in before and then it flashes...I also think that it disconnects the ECM because the car doesn't run right when the clip is shorting those two pins.

Re: engine light /service now light
I took my car (3rd gen) into the garage to have a number of things done, since having my car back my engine lights been coming on and off , when it does this It goes into limp mode and I lose about half the power of my car , after aroud 1-2 mins the light goes off and drives fine.
There's times where I can drive for up to an hour or more with out it happening and other times it will be doing it every 5 mins and can get very annoying to drive .
Thing I had done are - new distributer cap, inlet manifold gaskets, rocker box gaskets, new exhaust, new y pipe, de cat pipe, new water pump, tappets ajusted, lockdown cable ajusted , plus a few more things like breaks and that.
I've read codes and got code 43 .
Anybody got any suggestions ?

Re: engine light /service now light
code 43= Low voltage at electronic spark timing circuit (knock sensor/ign. circuit)
probably a poor connection at the plug in the distributor (ign. module)
