ABS fault codes

Can the ABS codes be read on my Vectra 1996 1.8 16V car.

My diagnostic connector is a 16 pin one under the handbrake

I have seen the topbuzz website and seen the bit about using a paperclip in
the diagnostic connector for the engine, tried it and that works for the
engine ECU.

Is there another 10 pin connector somewhere under the bonnet for the ABS ECU
or do I need to seek the dealer network. I have the ABS light lit on the
dash (and the airbag warning light) and slowly working through the faults
on the vehicle.

If anyone can assist with either of these or even suggest why the passenger
side doors do not unlock with the central locking any help is appreciated.

As a last note I have seen several versions of diagnostic reader on ebay.
Has anyone tried these and can say that they work with the 1996 Vectra.
From reading other posts I get the impression these are only for 2000 year
vehicles or later.

yes.

but not often necessary, what's the symptoms?

actuator bolt(s) sticking or broken wire to that side.

if you can get at it , give it a gooddose of WD40.
you might be able to get a better shot down the window rubber/felt seal.

I would question this practice. In my experience the oil can have the effect
of making the rubber seals that the windows run in swell slightly, making
them slower to operate (when electric). Others may disagree, but thats my
ha'porth.

(a differant one)

 

well it would h ave to be done with the window up anyway so hopefully the
glass/rubber won't get coated.
if he is cute, a steel ruler can be nicely used to hold the rubber back to
get a shot at the solonoid
the other trick is to pull the button off and go down that hole

There are no symtoms to speak of just a permenant light on the dash.

I will try to leave the battery off for a while to clear codes if this
works.

New car to me from an auction so working my way through the systems.

Thanks

if there is no fault, then it should auto reset in a couple of days.

a basic test - can you skid any wheels on hard braking in straight line?

if it's no then ABS is OK,

if you can skid a wheel then there is a fault.

there is one type of ABS unit vauxhall fitted inthat period which was a
complete cow!

have a look at a sintra group they all got it and many were replaced.

I found a 10 pin connector on a short length of cable under the ABS pump
block under the bonnet. Is is a black connector with a cap. It also has a
green gator, could this be the abs diagnostic connector?

I tried the end two pins with a clip to no avail, getting no flashing abs
light on the dash with ignition on.

The plug you have found is for the cruise control motor. Your car hasn't got
cruise so plug is spare.

 

Is there another 10 pin connector somewhere under the bonnet for the ABS
ECU

Main code reader plug but depending upon model the abs codes can't be 'paper
clipped'.

ABS often pump, relay or any of the detectors (or even wheel size
mis-matched). Also, may be obvious but check you have brake lights working.

SRS (airbag) light with stop on (SRS now ineffective) until reset (pig) with
diagnostics. Might reset and not return or may have a permanent fault.

Door lock solenoid/motor or micro switches in the effected doors (or wiring
plug!)

I hat cars!! I am going to see the not so friendly Vauxhall garage soon to
get a security card for the car. Then I will be asking the service section
to get a megamos fob programmed. I will ask what extra they charge to read
the fault codes.

I have been serching the web and a recently acquired set of TIS CD's.

Just found an article on the TIS that mentions the new design of Diagnosis
lead used in Omega B and saying how these will be introduced on to all
models.

It lists the 16 pin diagnostic connector.

Pins 1 and 2 unoccupied

Pin 3 Diagnostic lead for automatic transmission, central door locking
system and electrically adjustable sliding roof.

Pins 4 and 5 Ter.31 Gnd

Pin 6 Blink code, for Motronic, DDE 2.1 and Simtec 56.1

Pin 7 Diagnostic lead for electric seat/mirror adjustment with memory.
Motronic, DDE 2.1 Simtec

Pin 8 Diagnostic lead for electronic cruisecontrol, TID/MID and AWTS with
integrated electr. immobiliser

Pins 9, 10, 11. Unoccupied

Pin 12 Diagnostic lead control unit for airbag and ABS

Pin 13, 14, 15. Unoccupied

Pin 16 Ter. 30 +12 Volt.

An article on the web says the protocol is KW2000. but have been unable to
find this spec yet. Is it a I^2C bus? Can someone point me to any
information. It may now be well above my head but I still have application
books for the 8051 series controllers and books that contain several
communication routines.

Thanks Mel40, me thinks, time I went to garage.

The break lights work, new tyres all round. I have not tried the skid test
yet.

Discovered that Kw2000 is also ISO 14230. Way too complicated for me, scrap
that idea.
