Problems with gsx

[2gSpyder4g64]

Hey guys i just bought a 97 gsx, it has almost no rust and it was already taken care off : ).

its my first 4g63

Also English is not my first language so im sorry if my problem is not clear ;(

It has the CE , SRS , ABS lights on : (

It was automatic and then it was swaped to manual (i think he used a 96 tranny )
it was converted to fwd when it was auto (some guy told him to do that so he could do burnouts ) , so he didnt bother getting the manual transfer case and t he rear dif for manual trans.

I think the ABS light is on becuase he didnt get the abs front cv axles.
How can i check wich ones i have?

I already bought a 96 transfer case a rear dif with lsd, and the rear axles ( for lsd with abs), what else do i need to make the awd work?

The srs light i think its on becuase the previous owner changed the steering wheel for a new one and he didnt bother conecting the air bag again , but could it be the srs ecu that is damaged?


And the CEL the guy told me its one since he replaced the stock exhaust , but i when i looked under the car it looked liek the original ( at leats the diameter) line it only has a test pipe and a ricer can atached to the end haha, you guys think its posible that the CEL could be some emission stuff?

I agree with all three of your theories. The ABS light is on because one of more speed-senors are not sending a signal. The SRS light is on because the steering wheel doesn't have an airbag. The CEL is on because you don't have a cat.

You can try to get the right axles and see if the ABS will come back or you can delete the ABS and pull the bulb. You can get an OE steering wheel or pull that bulb, too. You can get a cat, a defouler, or something like ECMLink to disable the CEL. Others might have other suggestions. First, you have to decide if you want the ABS back and/or want the airbag back.

 

[2gSpyder4g64]

thanks jtm : ) i want to keep atleast the airbags i dont really care about abs haha.

I have an oe stering wheel and a talon airbag lying arround what would be the safest way to test , i heard i need to disconect the battery and wait atleast 20-30
mins , or should i leave that to an expert i dont want to loose all my teeth conecting an airbag.

Also i want to make it awd again this is what i got with the car.

im not sure if its a manual transfer or auto , so i bought a new one and the axle?
( i think thats how its called) its from when it was auto im not sure if i can use that one or a need a new one that came from a manual car.

Other thing that worries me is that it has a MBC but it doesnt has a boost gauge.
should i delete it or leave it as it is?

 

[jtmcinder]

Yes, you do want to wait after disconnecting the battery before plugging in an airbag. Having one go off in your face can ruin your day.

As to the MBC, I would hook a line directly from the turbo outlet (or intake) to the wastegate until you have a boost-gauge.

Can't help on the transfer case; not my specialty. But one warning: there's a good chance that putting ABS axles in will not bring back the ABS. These cars are known for breaking speed-sensors and/or the wires in the speed-sensor cables, which are a total pain to track down and fix. This is another reason why a lot of people just yank the ABS pump and swap in a non-ABS prop-valve.

 

[2gSpyder4g64]

ohh well i guess i can live with out abs ( all my past cars didnt had abs :O )

also scabed the car to see why the CEL was on and it marks error P1750 wich is the tranny solenoid i guess its because it used to be auto , do i need to replace the ecu or is there anny other way to get rid of that code?

 

[2gSpyder4g64]

Hey sorry to bump this , but i coundt find annything about the p1750 cel code on a manual trans, you guys think swaping the ecu will get rid of that code? also how do i check if i have an auto or manual ecu?

Thanks!

 

[95eclipseguy]

swapping the ecu will not get rid of the cel. I'm sorry my memory is bad, but if it was an auto and now a manual, just unplug the TCU and clear the cel. Also, if your returning to awd, you will need the drivers side driveshaft and intermediate shaft which bolts to your engine block just below the a/c unit. Unless of course the original one is still there.

 

[miguelmcv]

You will need both Front Axles (AWD) including the intermediate shaft.
To check your Transfer Case, check how many splines are, (22 splines Manual), (23 splines Auto).
To remove the code, Just disconnect the battery for a couple of minutes and the cel will clear, Disconnect the TCU, so it doesn't send the code again, reconnect the Battery, and you are all set.
Hope this helps.

 

[2gSpyder4g64]

ok thanks guys i think i have an auto tcase i counted 23 splines, i already ordered a new one

as for the tcu where i find it? sorry if its a dumb question i've never had an auto before :/

 

[Rsawd95dsm]

If your profile is correct... I didnt think you could make a 420a an AWD? some one chime in if im wrong and point me in a direction so i can read about it the punch myself for not knowing

 

[2gSpyder4g64]

well it says i have a N/T spyder wich is 4g64, also i just got a 97 gsx converted to fwd for some odd reason ? haha

 

[Rsawd95dsm]

O gotcha sorry about that then Just re read the whole entire post again and relized my mind must have forgot what i read the first time GL with it all

The TCU is located one side of your pedal (accel), If you remove the driver side panel of the middle cluster, you will see both ECU, the Engine ECU will be the very first one, right behind the radio,,,,,, if you go all the way down, you will see the TCU covered with a metal panel, Just unplug it and you are it.

I couldn't find a nice pic, but this is the area where the TCU is mounted (RED LITTLE CIRCLE).

Why in the world would someone go through the trouble of converting AWD to FWD usually it's the other way around.

Yes, It is, But some times finding an AWD Tranny is almost impossible, so the best thing to do beside spending a fortune, is a FWD Swap.

When I did my AWD Swap, I fixed the Donor Car and converted to FWD, I still have both cars, and I haven't get any kind of problems with my FWD (Swap car), My AWD (Swap car) gets more problematic then the FWD (Swap car).

Depending on what your future plans are for the car, i would get a flashable ecu(98-99). As for the airbag I've never disconnected the battery(ignition stays off) and so far I've never had one go off in my face.

 

[Doubleot]

The location of the TCU is correct, Sounds like you have your work cut out for you but I hope you follow threw and make this car back into it's former glory. Good luck and I can appreciate the dedication.

Thats what i wanted a 98-99 ecu, as for the plans with the car its going to be one of my "DD" because here you cant use cars with 8+ years 2 days a week, and im using it to go to my college clases haha so nothing crazy for now

Thats whay i hope too and thanks that means alot to me.

 

[miguelmcv]

Hey, I can see the TCU label on there (picturr you posted) .
You can't see it because is covered with that metal box, remove the metal box and you will see the TCU in there, you will see the TCU in there, if you see closelly in the pic, there is a lable on the side( that's the TCU).

It's right there sir, That is the tcu.

 

[2gSpyder4g64]

ohh really? haha i tought that was the ecu

i just unplug it?

ok so i unpluged it disconected the batery , waqited , and reconected and the cel was gone for 5 mins the nit came back :/

 

[miguelmcv]

Do not connected back, The TCU is for the Automatic Transmission, Because you have no Automatic Transmission, then the TCU is not needed, Just unplug the TCU and leave it like that.

 

[2gSpyder4g64]

no i mean i reconected the batery i left the tcu unpluged

 

[miguelmcv]

If your CEL came back, then it might be because you have no Catalytic Converter, You might had 2 codes, Transmission Code, and Cat,, You have to check the code again and see what code is it.
I am sure you will not get the Transmission Code any more.
Check the code and report back with results so we can guide you.

Some news a friend borred me his boost gauge and it looks fine i think

The vacum was at 10-11, and the boost arround 9psi (sounds good since i dont want to put much stress on the engine yet )

as for the CEL i got code P1600 now :/ wich is something related with the TCU :/

ok i'm sorry to bump this but i think i found how to solve the code p1600

I found this

http://www.dsmtuners.com/forums/newbie-forum/266018-ce-code-p1600.html

The manual ECU is supposed to have a harness that grounds ECU pin 91. The auto ECU's harness connects pin 91 to the starter relay power. Not sure if this is your problem but it may be. Let us know what you find.

that makes sense the pin 91 is "Park/Neutral position switch ", and i think i still have the automatic harness.
How do i ground it? ( i have no experience with this kind of things)

any thoughts on this? :/
