Help with vr ss - getting abs codes

[djses9]

have had a problem getting any codes for abs system in my vr ss.
I have tried shorting the 5th and 12th pins on the diagnostic connector but get nothing. http://forums.justcommodores.com.au/images/smilies/hmmm.gif Engine codes work fine (5th & 6th pins) does anyone know why???http://forums.justcommodores.com.au/images/smilies/bomb.gif
I need these codes as my ABS off light is on and hydraulic brakes not the greatest.

any slither of help very much appreciated!
cheers.

have you replaced your diff lately???
when i replaced mine i didnt notice at the time but the new diff didn't have the little goldish coloured cog bits for a abs sensor thingy so thats why my abs light is on

no mate - my diff has the cogs + sensors but just cant get any error codes. like usually i notice the fan turns on while getting engine codes. for the abs codes nothing happens -- just like turning the key on!! :hmmm:

I thought the VR used an earlier version of the Bosch ABS which did not give fault codes but I could be wrong. However, one thing I know can fail is the large connector to the ABS unit which can corrode where the terminals are especially if the car is degreased and water gets in the connection.

If you don't get any fault codes, your ABS itself module may be the problem.

I think that there was a change made with VR II, when data became available out of the ALDL connector (for xcop, that's the socket under the steering column you've been using so far).
