So other night i did few hard braking and abs light is now on and no abs. Wheels do lock up

 

i have link g4 on my 1998 r34 gtt which has usb interface but i think that only replaces the ecu as I still have consult port

 

what I am not sure is if consult os reading and accessing ecu through the old ecu

so i bought consult and tried both consultz and nissan data scan 1 and neighbours can access the ecu or any other ecu as hicas was also removed

 

so i googled ans jumped pin 4 and 8 and still no flashing on abs light indicating what the problem is

 

read the link ecu and had no error and it is locked by tuner so can't access it

 

what are my options here to read abs fault and fix it?

Mechanic will have same tools as me

No. Take it to a mechanic who has a PROPER scan tool. Made by Snap-On, or any of the other $10000+ workshop grade scan tools that will connect to and read from EVERY make and model (with the appropriate licenses, of course).

Consultz and Nissdatascan etc are NOT proper scan tools. They are a valiant effort by talented amateurs.

right but where is the joy of fixing it yourself?

Link ECU replaces the main ecu as it is plug in so my question was does consult port uses the standard ecu to connect to hicas and abs etc / in another word, were you able to only access them throuugh standard ecu even though they were different ecus?

 

has anyone read abs module codes on nissan skyline and if so what software and port have you used

The joy is in getting the problem identified, because you cannot do it yourself unless you have drug money.

All CUs are on the same Consult bus. Access to the others is not mediated by the ECU.

I already told you - there is nothing out there. You need a workshop grade scan tool. This is a large handheld device that comes in a blow-mould case with a bunch of different cables that allows you to hook it up to diag ports on Nissans, Hondas, Toyos, BMWs......get the theme here? Or, you need an actual Nissan Consult tool. Same thing, just limited to Nissan only and more guaranteed to have the correct protocols and lookups for every Nissan.

There is only one diag port on your car. The Consult port.

Took it to two nissan dealer and they won't touch it as it has link ecu

thinking independent garage but haven't found reputable one

 

you can buy consult on ebay for relatively cheap price, does anyone know if there is a consult bus such as can so all ecus can be reachable via a bus lane without going through main ecu?

Yes, that is the definition of Nissan Consult. All the CUs are on the bus.

Any Snap-On, or similar scan tol, as possessed by ANY decent mechanic these days, WILL read all the CUs. I worked out what was wrong with my HICAS using a workshop grade scan tool.....20 years ago.

so I mapped the pins as per this link and my maxicom does not support it 

https://www.autelstore.co.uk/wholesale/autel-maxicom-mk808-diagnostic-tool.html?gclid=Cj0KCQiAqo3-BRDoARIsAE5vnaKsLh-sn8cKvzkdH1CrqG3mb3u-DT01nvn1Y5rBSiwnTwzv8FPTw-MaAvC_EALw_wcB

 

it looks as I am out of any options, can't find any consult 1 or consult 2 reader. 

as i understand consult 3 or consult 3 plus won't support my car. about to pull my hair.

so here is my experience and update for people in similar situation 

 

https://www.autelstore.co.uk/wholesale/autel-maxicom-mk808-diagnostic-tool.html?gclid=Cj0KCQiAqo3-BRDoARIsAE5vnaKsLh-sn8cKvzkdH1CrqG3mb3u-DT01nvn1Y5rBSiwnTwzv8FPTw-MaAvC_EALw_wcB

can read skyline r34 however doesn't have consult port adaptor.

 

so also bought below and confirmed it can read abs. I used the adaptor from consult to OBD and confirmed the Autel can also read the abs module.

I will map the pins using my multi meter and post back for anyone in similar situation in the future.

I saw a code saying ABS motor off, so back to basics, fuse was gone. Ouch that hearts by missing the most simple thing and going to get ecu to read it

      Short shifter r34

      By PLYNX · Posted

      Don't do it if your gearbox box has already having syncro issues. The short hifter will put a greater load on them. If you must I remember Nismo did a shorter shifter, with the top part being physically shorter and the part that went into the gearbox was the same as stock. In saying that I've had a C's short shifter (I think) in mine for many years, which was given to me as the previous owner was not sympathetic to the gearbox. Thus forwarned I was careful and had to modify my normal changing style. You have to be super accurate with your clutch and shifts

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      Well, after a week of daily driving and having to crawl out between the wheel and the side intrusion bars. I got myself a quick release setup. I went with an NRG short hub and Quick Release with some cute heart cutouts on the pull tabs. Nice and matchy matchy with the rest of the interior accents I have going on.  The only downside is the total stack height even with the short adapter is longer than the old HKB boss kit. Luckily I had some adjustment left on the column so move the wheel away.

      stock shifter with new bushes, springs and cup will improve it. Gktech do all the bits. The opinion as the years have gone on is the redline is not great in old gearboxes.

      Hi all   what short shifter do you use on your skykine r34?   my synchronous does have a problem and i was getting huge delay and grinding sound between 2nd and 3rd, did put shockproof red heavy stuff and it is great now/ no issues   would in your view short shifter screw this up?   people seems to suggest/ use cube short shifter and there is standard and premium. Seen review of premium as much better and less play. Thoughts?

      R34 oil and timing belt change

      By GTSBoy · Posted

      Yeah, there's a bit of a density and friability difference between pebbles and any of those other things. Silicone will definitely float in oil and so will be mobile enough to move around. Although, again, if it is upstream of the filter it really shouldn't go any further. I would only ever worry about silicone when it is in places downstream of the filter. Upstream of the pickup is a whole 'nother matter. We've all seen what that does. I have seen the most abominable crap settled out in industrial gearboxes, trunnion lube systems and the like, without any sign that any of it has touched anything in the machine. Just chilling in the bottom, waiting for the inevitable operator error that causes the whole machine to need to be dismantled for repairs.
