Hello, my name is Mark and I will try help you with this.
The ABS system has a self test function. If the light is on then there is still a fault in the system. If the light stays on then you will need a scan tool to read the fault and then carry out the required repair.
hi i have a scan tool and it keeps saying system function test activated /static no define. the car has done 165 miles the abs unit has been changed
What kind of scan tool do you have?
pro scan v400
Does it give you any codes?
system function test/static no define
Looks like your scan tool is not compatible with the vehicle systems.
