HELP: central lock non-function and ABS on

[nsbone_1988_520i]

may be we can help. Not working is quite vague. You have 5 to 6 ways to operate the central locking, front doors knobs (and indoor handles), front doors keyholes, trunk lid keyhole, and keyless. Not all work the same way, knowing behavior for every operating alternative will help diagnose the fault.

Hi Javier,

THe car doesn't have keyless. Otherwise all other ways don't work. (front doors knobs (and indoor handles), front doors keyholes, trunk lid keyhole). Checked all fuses are fine and replaced anyway some of suspect ones. worst case it could be the central locking module under rear seat???

I am attempting to take out the microswithc which might be stucked at dealock or lock position...

Roof? Interior lights?

Not working means nothing at all to me, Am I right?

Guess though that you can lock/unlock mechanically each door/trunk by key or manually. What about the gas filling port door? Any other issues?

Do you, at least, hear clicking relays at Relay Module, under the rear seat, besides General Module.

Hi Javier,
Thanks for responding.

Not working means= no response/clicking relays if i turn my keylock using key either locking or unlocking or doublelocking. i had forced gas filling door open using screw driver and taken out the rubber latch.

I can lock from the driver side, but i can't unlock using the "battery-flat" method (something is really wrong).

I hope u get what i mean???

thanks again..

Interior lights? I just can not found reasons for that general failure in the central locking having no issues at all in other GM related functions.

In this sentence, do you mean manually?

I can lock from the driver side,

Manual lock from driver side is possible. But my manual unlock is not working. It is working on my other car. Central light is working...

i have to get to the microswitch, but it's very difficult (although Johan/Sean's Page make it seems so easy). I wont' give up though...

BTW interior lights is also working...

is e32 central lock module under the rear seat the same as e34? can i interchange to see if that's the problem?
