Actron CP9449 BrakeScan 2000 Mustang GT Bosch unit failure.
Read a lot before purchase - that is I verified my vehicle covered. Plugged in.
Can't connect. Per the Ford shop manual (found online!) testing with volt/ohm-meter all results point to ABS controller. Plugged the CP9449 into my other Ford (F150) - worked fine. Sent Bosch ABS off to 'cheap-abs' and unit repaired, returned in 4 days. Installed and tested car. ABS works, Traction Control works, CP9449 found the original code "abs unit failed" - erased code and "Passed!" Drove car on wet (aka slick) road and tested brakes and traction control. Function now normal.
So, if the CP9449 doesn't read - just maybe you have a vehicle not covered OR the abs module is DECEASED. A little study goes a long way.
Side note for other ABS repairmen (or women!) The Yahoos who assembled the input brake lines overtorqued the hold downs. The hold downs actually expanded where they seat against the flare of the brake lines. Getting out somewhat damaged the threads in the aluminum hydraulic block. But after grinding down the expanded part of the screw/nuts - managed to get re-assembled and no leaks. There were enough threads left to hold. The four output brake lines only needed a wrench to loosen and final tighten when re-assembled. Note: video available to get out the Bosch ABS if you don't want to undo the brake lines. I change fluid every two years anyway so removed the whole unit. The issue with the input lines was only hassle.
No issues with this unit for me! walker
