Another ABS/TCS code puzzle...

[Martyn27_uk]

I'm writing this over munch and in haste, if it's not clear let me know what you need to know!



For quite a while now the ABS has kicked in at slow traffic stops. ( 1993 manual 5sp unmodified ).

Thinking it might be a wheel sensor I pulled ( or tried to pull ) the self-diagnosis codes this morning.

I know the TCS and ALB share the same wheel sensors

I’ve got the relevant manual page in front of me ( 19-31 ) but can’t make sense of what I see.

Can anyone interpret this?


NORMAL SEQUENCE ( diagnostic plug not bridged )

Ignition switch on, engine off

OIL BATTERY ALB TCS all on constantly ( SRS Airbag light glows briefly, then switches off )

Ignition switch on, engine starts and during normal driving

All tell tale lights off



DIAGNOSTIC SEQUENCE ( with the bright blue connector bridged )

Ignition switch on, engine off

OIL CEL BATTERY on constantly ( SRS Airbag light glows briefly, then switches off )

TCS flashes once – as the doors are locked by my car’s security system - then remains on constantly

ABS light off

Ignition switch on, engine starts

CEL light remains on, all others, including the TCS light, go off.

ok, so it's an echo.....

ABS section, go to page 19-44, (page 44 on the pdf file) this gives the ABS flashing lamp code meanings!

TCS section starts page 19-82, (page 82 on the PDF) explains the TCS flashes!

what do you mean ABS kicked in? the pump, or the lamp???

the pump automatically recharges the system when it detects a drop in pressure in the abs reservior.....

& that's where I'm looking :-0

My guess is, as the ABS light isn't displaying as I drive then no fault code is being sent to the system, so there are no fault codes for me to download!

There IS a fault though! I wonder if it's possible that the wheel IS actually locking up at very low speed ( but surely I'd notice! )
