check for error codes the ABS module... i suspect the front right wheel sensor might out of whack - did you drive in puddles of water? or hit a curb or something?

the speed data is not plausible and the ABS might be setting the codes...

not to say that the mechanic is wrong, but a sensor might an easier solution...

connect INPA and read ALL error codes, as when you read them in conjunction with each other, you might be able to determine the real reason for the errors...
