Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
It means there is something wrong, hopefully a wheel speed sensor or harness.
We need to get the car scanned for codes.
There will be one or more codes stored in the ABS module.
Can you get this done please?
A scan will cost about $50.
A wheel speed sensor is about $200 for rear, $600 front, fitted.
Have you had your car looked at?
I hope my advice has been of assistance to you.
