I wrote this a few years back when I repaired my ABS PUMP.
Hi,
I am new to this forum but not new to the Jazz as I have owned it for 14 years.
I have just repaired a faulty abs pump. Before you spend out any money you can try this, turn the ignition on but don’t start the car. Place a long screw driver on the pump to hear if it’s working, if not disconnect the battery negative lead. Mark the pumps top edge so you put it back the correct way.There are 2 4mm Allen bolts hholding the pump on, the bottom one you cannot see and is a bit fiddly to access. Pull the motor straight out be gentle do not twist the housing left to right as you may damage the two pins that power the motor, keep the gasket as it needs to go back on when reinstalling. I used a multi meter( I am an electrician) connect to both pins and set the mult meter to the ohms scale if the reading is about 0.7 ohms the windings are still good and the motor may just be stuck. Tap the base of the housing a few times to see if you can release it, spray with silicon spray or actf50, just not wd40. I Applied applied 12vots to the pumps pins and it worked fine. On reinstallation my sure you the mark that you made is on the top. The pins look the same but it will only go back the correct way. Be gentle pushing the pump motor in as it’s a bit of a faff to locate those pins correctly. Replace the Allen bolts, reconnect the battery. Start car and hopefully your abs light goes off.
