Codes For The Active Lsd Computer

[guru_ray]

Hi all,

I have looked far and wide but i still can't find what I am looking for.

Does anyone have a list of the codes that the control module for the A-LSD flashes out when an error is detected?.

On the underside of the module in the boot is a light that flashes codes in the same way that the ECU does.

Edit 'my car is a 1993 r33 GTS-T manuel.

Thanks

Ray.

True shit ay ill have to have a look at that, never knew that ECU had a flashing LED on it.

OK,

This seems to be a hard question.

If someone out there wants to do me a favour?

Moanie suggested in one of her posts she knew what one of the the codes was on her A-lsd module.

If somebody wants to send a PM to Moanie ask if she can post the codes here, if she has them.

Moanie if you don't have codes for the A-Lsd module where did 'read' the TPS error?

I cannot send personal messages until i have made 10 posts.

I don't see the point in spamming threads just so I can send a message.

If the answer is out there lets get it up here!

ps. if you send a message to Moanie post you have done so, so she don't get a mailbox full of spam.

I don't know if you have seen This but it has links to other topics on the SAU forums that have lot of info on the Active LSD option in R33 skylines. Maybe try checking it out first. It may clear your error for you but doing some simple bleeding.

Dead link for me?.

I have studied all the links in the sticky at the top of this section of the forums if that was what you were referring to.

I am trying to read the codes so I can get this thing working properly, I am single spinning at the moment.

And have two codes one is TPS the other I don't know.

Thanks all help appreciated.

Ray.

[PM-R33]

You using a stock ECU or aftermarket?

[guru_ray]

Stock ECU is in the car now.

Codes I have are 75 which i believe to TPS

And 62 which if the same as the Attessa codes would be front and rear right G sensor???? I don't think the GTS-T has G sensors???

Will be going with apexi powerfc later and splicing the wires for the TPS, If I get the A-LSD working that is.

Sorry try this link

The other link didn't post properly

What error codes are you getting?

[guru_ray]

Thanks I have read every thing there all the links.

Codes are 75 and 62.

Cheers

The G-sensors it is referring to is the wheel speed sensors. This is what your ABS uses also, hence if you have an ABS fault, your A-LSD goes to shit. This becomes a problem when doing stand still burnouts and locking up the front wheels. The ABS sometimes gets a fault since the front wheels aren't spinning but the rears are and then the diff goes into single spinner mode. Hence not the best diff if you like doing stand stills.

And another piece to the puzzle fits in,

Always wondered why the car defaulted to single pegger when I did a brake lock burnout. Thanks mate.

I could be going down the wrong path but these are the codes for the Attesa ETS ECU in the R33 GTR.

The diff is the same one as the V-Spec, so I would assume that it would use the same/similar computer to control the diff & ABS.

Going off these codes 75 is the Throttle Position sensor. This normally looks for 0.5v fully closed. You can check this with a multimeter and move the sensor until it has that reading.

PM-R33 looks like he has covered the error 62

By the time we die of old age we should have this thing pegged.

[PM-R33]

Haha yeah, it is the most over complicated diff in history. I think one day im just gonna get rid of it and put a 1.5 way into it, it's such an annoying diff. Great when it works normally, but a pain in the ass when it decides not to work.

Ok wheel speed sensors, where the hell are they?.

I would have thought that they would be on the hubs, with a magnetic reader and a magnet spinning with the hub?

No wiring going to the hubs at all.

There are two sensors of some sort on the back of the diff itself ether side with two wires each. I followed these wires and they go to the Hicas Module.

Stupid diff.

On a side note I have a hicas lock bar. The wiring for the hicas does no need to plugged in to make this diff work does it?

Well done chief, that are they!

Any ideas on how test these for correct operation, is there a resistance test?.

[PM-R33]

Nope HICAS does not effect the operation at all. Honestly i have never looked for the wheel speed sensors so am not sure.

They are definitely the sensors but I do not know where they go, can let you know tomorrow. But I suspect it may be of no use to you as I have a GTR.
