ECU Help!

[pro_gmh]

I just did an ecu test on my mates vl, come up with codes...

13 - Temp sensor?
23 - Throttle sensor?
24 - Neautrul switch
31 - system pass?

The vl runs fine, should he do somthing bout these codes?

If it aint broke....

those are normal if you didnt run through the entire procedure.

11 crank angle
12 Air flow
13 Coolant temp
14 Speed sensor
21 Ignition signal circuit
23 Throttle switch circuit
24 Neutral Switch circuit (auto's only)
31 Air-con circuit
32 Starter signal circuit
34 Detonation sensor circuit (turbo's only)
44 Satisfactory operation (air-con models only)

pulled this off another thread, according to that there nothin you need to worry about except the temp sensor for your coolant there. i dont think that should spit out? give it a check, mayb change it out/flush radiator an the rest, if it runs a little hot. i know the rest of the codes are normal if you dont follow the procedure exactly so nothin to worry bout.

mine come up with 12 and 31..
the air flow (12) can that get fixed by adjusting the afm to the .382 ohms?
and also my aircon circuit (31) is that coz its completely outa gas (from when i changed engine)? or is it the actual circuit..?

31 is a pass if you have no aircon or non factory aircon I believe.

the air con comes up normally. you have a proceedure to follow that should cancel the code. then check again. there's another thread here where i wrote the proceedure down.

ok kool.. wot about air flow?

[pro_gmh]

So what is the proper procedure?

[Bax]

About how to cancel them, get in and drive over 10km/h aircon on and off, go through your gears, etc etc. Just do everything and anything.

[megee83]

to cancel 14 - you got to drive over 10kmph
cancel 23 - push the accelerator down
cancel 24 - put it from neutral into any gear
cancel 31 (if a/c) - turn it on an off.

31 (non a/c) or 44 (a/c) will also come out if everythins good. if the car runs fine id jus leave em, doesnt matter, if there was some sort of prob an i wanted to check the comp id go through an cancel them all.
back to the first question but, are you sure you got 13 an not 14? cos you should have got 14 to start with... mayb a miscount?

also you will get 32 if you run the test without startin the car up.

Im not 100% sure on what i got, i couldnt really concentrate on the flashes properly that night lol, but i will probs have another go. coz of the error 23 he went and got a TPS lol but its all good.
