Hi,
The abs system on my Multipla 1.9 JTD is coming prematurely, after a few miles the ABS light comes on and the brakes are okay. I have checked the two sensors at the front and they seem to be working fine but I cannot find the connectors for the rear sensors, any ideas.
Secondly I would like to know where the ECU plug is and if you can get a fault code reader for this MPV. Thanx.

How did you check the front sensors?

with a multimeter but the front N/S side sensor is brand new anyway and I have found the connectors for the rear sensors and used the multimeter in the same way I think I need a oscilloscope to check the actual Hall effect sensors though?

Dealer can do it instantly using examiner.....so easy & quick/accurate.

One thing is remove the abs module multiplug,seen this corroded/water ingress many times.

where is the abs module plug located?:idea:

On the abs module.

Took it to Fiat garage today put on diagnostic and double wammy, the front N/S sensor is not recording the correct number of teeth and either the same side or O/S front wheel bearing has gone.
Thought the diagnostic was cheap though and well worth £25 at Bostins @ Milford in Staffordshire, friendly bunch and efficient.
Taking the car back tomorrow get new bearing and maybe a phonic gear!
Remember BOSTINS OF MILFORD (STAFFS) are:worship:

£25 is cheap

I would still quickly check the connector though as this throws up o.c. errors.Behind battery is abs module,on left side of it is a long black connector.To disconnect pull the 'handle' towards you(will be tight) like your opening a drawer,refit in opposite way.

New bearing and no ABS brake problems this was well worth the money. Car is now cool in this heat!
