ABS light on

[mecevans]

my abs sensor has been on ever since the GE-auto to GE-manual swap. i never wired in the neutral switch, it just started with no issues and without the clutch needing to be depressed. it turns on after 15 feet of driving and never turns off. under hard braking the driver side front tire locks up first.

 

[mecevans]

anyone got an idea whats wrong?

 

[jetjock]

About what, the cluster speed sensor? Do you have an engine code for it? Have you check it using the cruise control diags?

 

[mecevans]

yes my abs light is on. TSRM says to check the speed sensor in the gauge cluster.

 

[jetjock]

20 questions eh? Ok, I'll take the same two as before...

 

[mecevans]

no engine codes at all. just and ABS light. what diagrams??????? im going off the troubleshooting chart. tsrm say to check the speed sensor due to code 4 and 5 and NO B codes.

TSRM


"inspection of speed sensor
check that there is continuity between A and B four times per each revolution of the shaft. if continuity is not as specified, replace the sensor"

So you checked the ABS system for codes?

[mecevans]

yes i checked for ABS CODES. i get ABS CODES...TYPE A 4 & 5, TYPE B no codes.

tsrm

" if there is no indication code for type B perform diagnosis and inspection (see page BE-55)"

did anyone READ MY POST?

Appears he didn't

I'm trying to help you but I don't have much time. I'm not supposed to be here and come midnight I go back to being a pumpkin. If the cluster sensor wasn't working you'd get an engine code so it appears yours is OK. And when I said "diags" I meant the cruise control diagnostics. They provide a quick way of testing the cluster sensor...

 

[mecevans]

yes i did perform the diagnostics i gave you the diagnostic codes that im getting. im really confused now. if my cluster sensor is working and i get these codes what should i be doing?
what do i check next?

 

[mecevans]

fuck im stupid. i got the ABS with cruise control mixed up. no more late night posting for me!

 

[jetjock]

Page BE 55 involves the power seat. BR 53 involves the ABS and your codes don't jive with that. One of us is confused...

edit: Lucky I took a lot of time to check or you'd have looked dumb

 

[mecevans]

ok heres my question....... if the w58 is from a non abs car and i put it in an abs car theres nothing i can do to fix it correct? i would need an ABS w58 and motor harness?

 

[Poodles]

IF the sensor rotor is in the tranny, you could just pop the freeze plug off that blocks the location of the rear speed sensor.

Gotten conflicting info on if they put the rotor in all the trannies or not...

 

[jetjock]

I'd imagine you'd need the rear speed sensor but until you come up with some valid codes I can't tell.

edit: beat by the dog...

 

[mecevans]

my new motor and transmission are non-ABS though, so even if i get the sensor i have to change out the damn harness cause there is not abs plugs on it.

damn

 

[Poodles]

Plug should be on the harness still...

 

[mecevans]

Plug should be on the harness still...

thanks for the help and sorry for the confusion.


so i need to go to a yard and find a sup with ABS and get the sensor off the trans? install it in mine then there should be a plug and ill be golden?

 

[Poodles]

IF the sensor rotor is in the trans, if not you either need to add it to yours (open it up, dunno how difficult) or replace the tranny.
