Why are your abs light and brake light on for a Jeep Grand Cherokee?

Answer 1

Go to a parts store that can check your computers codes, if it is on constantly it is a hard code and something that is actually wrong, not just a temporary problem. ABS would be a sensor or something for the ABS most likely.

If all of the lights are on constantly, and you have been very good with all your maintenance and repairs and have not been in any kind of accident or driving off road, I would suspect you have a major electric issue, such as the PCM or ECM or BCM. Not sure exactly what control modules the Dakota has. Also be aware, that in most cases, multiple types of scanners may be needed for checking multiple systems and is usually the case for ABS systems, so a standard code reader/scanner may not pinpoint your problem.

Answer 2

first things first check engine light is on for a reason, you need to find out why, now as for the abs light , this comes on when there is a problem with the abs sensor located at brake, this could be something as simple you just need your brakes replaced

Answer 3

Those lights are on because the computer has detected a fault and set a code. You will need to have the system checked with a scan tool.
