Title: ABS codes (with Alex's tricom lead) ?
Post by Tekno on Jan 20^th, 2010, 5:46pm

Hello

My problem is abs fault bulb coming when I drive over 12mph

Can anyone tell step by step how to read abs codes?

I just get PWM Server no response -error

This is what I've managed so far:

Tick the Ford option diagnostic mode - towards the bottom right of the box in your screen grab.

You may need to click request a few times before it works.

Should the car be driven first so abs/tcs -lights illuminate?

Ask Tompion how to resolder the motor plug wires in the ABS module ;)

Quite likely as Gozz says but first check fuses 46 & 47 (It’s only one of them but I can’t remember which fuse is for the pump) & that power is getting to the ABS module plug – the 2 pairs of heavy gauge wires. If you unplug the pump & connect it to those wires in the multiplug you’ll test the pump & the feed at the same time (they are permanently live so take care not to short them).

If the pump & power are OK then it’s quite likely the module needs repairing:

The link is for the later type of ABS but the same repair can be done on the earlier type.

ABS and TCS works as long as i dont exceed ~12mph. Also if I floor it from stationary, TCS works as long as tires keep spinning. Then when I stop accelerating more, abs and traction control bulbs appear and also abs and traction control is gone until I restart car.

I assume from that you have the earlier type of ABS (module mounted under the valve block) as with the later type the light would normally stay on.

It's passing the static test but failing the rolling test.

Here are a couple of links with tests for the pins depending on the type of controller not that it's very conclusive as it doesn’t test both pins and they often test OK when not under load.
