I work in the auto parts business and this code indicates that something is wrong with your anti lock brake system....a professional mechanic would be able to tell you exactly what it is. It could be a sensor.
Rear wheel yes, four wheel was an option.
Got a '98 Durango and the mechanic said it kicked out a error code of 63. It's related to the ABS system, but I'm still looking as to exactly what.
Change the abs motor.
Anti-lock Braking System
The speedometer signal comes from the ABS sensor on top of the rear axle. The trans also has speed sensors on it for trans shifting.
A bad abs relay would cause this.
yes
Yes it could.
Change the sensor located on rear-end housing
The "main relay" is inside the abs computer. If you have the Main Relay code, the abs computer has failed.
There are 2 speed sensors, check the one on the rear differential also.
It is on because the abs computer has detected a malfunction and set a code.
