ABS Light on

[Willys]

I have a 97 850 non turbo. The ABS light is on all the time. We had
the brakes replaced and all the sensors within specs. Any Ideas?

Also, I can not find a data loger that will work on the 97. Any
Ideas?

known fault with teh ECU's

You can repair them yourself if you can solder or they are fixable by
people on ebay for ~£90 ( UK pounds)

let me know if you want a link to teh picture that shows which joints to
resolder.

In case other members has the same problem under here is illustrations on
how to fix. It is in Norwegan but
illustrations should speak for themselves. It worked for me and took
approx.2 hours to uninstall, open the box
and find and fix the broken solder and then re-install the box again.

It is important to use a torx E5 to unscrew the box.

For datalogning you can use a windows computer together with VOL-FCR
software and the appropriate interface cable.
