    Constant check light with bridged service connector

    All,

    trying to turn off my check light (or at least find out what's wrong with it) and i get no blinks/flashes when the service port is connected

    i know i have bridged it successfully as i can turn it on and off and i get a change in engine tone (due to the ignition timing going from static/mapped) just no flashes

    i've removed the 7.5A fuse as per the reset procedure, still nothing!

    any ideas? i searched on here and a few threads popped up but none of them had resolutions

    Thanks!

    Funny you say that. Replaced my dash bulbs with leds. After a few weeks check light came on but car ran perfectly. Got sick of the red glow and replaced with normal bulb. Problem solved... Wait a minute. Might have the same issue with me exhaust temp one now.....

    Mine was the same. Had the capacitors replaced on the ecu and I'm now getting a code for the first time when I bridge the service port. I also checked and cleaned any grounds I came across too.

    I didn't do the soldering myself as it looked a bit precise for my unskilled hand. I took it to a local computer repair shop, in fact the bloke in the shop told me it what a pain double sided soldering was..

    I do have some info though. There are 6 caps on the board that are the usual culprets. The shop replace mine with the following:

    1 x 35v220uf
    2 x 10v470uf
    2 x 35v33uf
    1 x 35v47uf
