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.

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! :bunny:

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.

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?

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.

Thanks I have read every thing there all the links.

Codes are 75 and 62.

Cheers

Ray.

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

Error Codes:

1,5 Front right wheel sensor and circuit

2,6 Front left wheel sensor and circuit

3,7 Rear right wheel sensor and circuit

4,8 Rear left whel sensor and circuit

11,21 Front right inlet solenoid valve and circuit

12,22 Front left inlet solenoid valve and circuit

13,23 Rear inlet solenoid valve and circuit

15,25 Front right outlet solenoid valve and circuit

16,26 Front left outlet solenoid valve and circuit

17,27 Rear outlet solenoid valve and circuit

31,32,33 E-TS solenoid and circuit

34,35,36 E-TS fail safe solenoid and circuit

41,42 ABS actuator relay and circuit

43,44 ABS actuator motor , motor relay and circuit

45,46,77 ET-S/ABS control unit ground and circuit

47,48 E-TS/ABS control unit power supply and circuit

51,52 E-TS actuator motor and circuit

53,54 Pressure switch and circuit

55 Air bleed switch and circuit

56 E-TS oil level switch and circuit

61 FR and RR G sensor 1 and circuit

62 FR and RR G sensor 2 and circuit

63 FR and RR G sensor 1 or 2 and circuit

64 G sensor 1 power supply and circuit

65 G- sensor 2 power supply and circuit

66 Side G sensor and circuit

75 Throttle position sensor and circuit and sensor

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?

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

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.

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
