Hey guys,

I'm having problems with my 'check abs' light coming on at speeds above 90km/h which to me suggests a speed sensor issue. (Just a guess)
I've recently had a few components of the braking system replaced (rotors, pads, brake lines, master cylinder) by the mechanic (I supplied them) and his diagnosis at this stage is that I've supplied the wrong rotors...
I've also thoroughly cleaned all the sensors.
To my understanding part# RDA130S is correct for slotted rotors for an EB with ABS but again, I could be wrong.

Now he reckons he's hooked it up to a scan tool (quite doubtful) and no problems have come up but I found this tech document: documents.php?d=48 and was wondering if somebody could shed some light on how to go about this...

How do I go about connecting the pins?
And how do I know what codes its giving me?
Does the abs light flash or something?

Better yet, If its as simple as it seems and somebody would be willing to perform this for me I'd be happy to drive out to you and buy you a 6 pack for your troubles etccc :P

I just don't have the money to gamble on replacing the rotors and the light coming on each time I accelerate onto the free way is bugging me...
It might even just be something simple like a dodgy sensor :S

Best regards,
Luke

you can short out a couple pins in the OBD & it will flash the error codes.

Also remove each sensor & give it a good clean. sometimes metallic material builds up on it & it causes the sensor not to function properly. (This has happened to me).

Worst case scenario you made need to replace a sensor or two. Not really bad scenario but it might mean a trip to the wreckers.

Ah okay so I presume you just run a piece of wire from one port to the other? (This is all new to me haha)

I've cleaned the sensors (they didn't seem to be too bad)

And yep, that's why I want to do a diagnostic test to determine whether it's a dodgey sensor or I've fitted the wrong rotors...

Cheers,
Luke

mate the rotors should have ABS sensors in the inside of them (when looking at them from inside up & outside down).

If there's no ABS Sensor then you need to change your Rotors LOL.

See the pic. If there's no ring with gaps then you dont have an ABS type rotor.

From memory my EF OBD had to have pins 6 & 7 shorted (I used a paper clip & unwound it)
