Posted by Peter Mashiter on July 29, 2017, 8:41 am

Year of Manufacture *: 1993

ABS fault light on (No symptoms)

Early round 9 pin diagnostic connector under bonnet!

Question is..... is there a way to assess blink code through pin out on this beast?

There is no diagnostic function on this system.You need either the dedicated Bosch test rig or check the system manually from the ecu located behind the battery.First item I would check is the over voltage relay located behind battery.This has 1 or 2 fuses in the top.It is also very easy to check sensor resistance on these. 2 fronts and 1 in the rear axle.Are there any cold starting or running issues,as this relay also powers the KE jetronic system?

This animal does not have a over protection relay? Unless it's well hidden!
Only has 2 relays on the ABS pump body under the plastic cover!
As to where the ABS ECU is?

Remove the battery and the plastic water cover (if fitted).There should be a plastic support frame that holds the Bosch KE jetronic control unit .Release the metal clip and the Abs control module should be behind this.The overvoltage relay is usually bolted down on the aluminium frame to the side.The relay may have a black plastic sleeve over the top of it.

Hi

AD ABS book 1 covers this, looks from the info OMITEC did a dedicated system tester for this,(not a fault code reader !)

I have no experience of this system but have worked on others with no self diagnosis.

have sent you the WD via email if it helps
