ECU codes - how do you pull them?

[Martiny]

Hi All

In my flabbergasting attempt to fix my secondary boost, I would like to check if there are any ecu codes stored.

Does anyone know, or have link to, the procedure to read the codes on a Jap 92 please?

Thanks!

Martin,

Do you know of anyone that has a spare ECU sitting around? maybe ask someone if you can borrow.

Around page F150 - you will find info. on the ECU.

On page F178 - you will find the Troubleshooting guide.


When I get a moment, I'll have a look through also to see what is there.

Yes, Glenn

Henning has an * bit one. I hope to go dwon there next week, and put that in my car.

Am also going to rig it non-sequential and see what that proves. At the moment I refuse to be beaten by this thing! But Rotechniks lurks in the background as my last resort.

Probably would have been cheaper to go there in the first place, but then, what would I have learnt in the meantime? Zilch!

Thanks, Glenn

Ive got all that in hard copy. But thats using the Mazda SST. I know theres a way of jumpering pins and usning an LED or the engine light (dont know if I have an engine light?)

they dont have an engine light until 98? in japan. they do have some kind of code reader thing that will plug into the diagnostic box, and give you the number
