Re: 97 jeep grand cherokee abs issue
 

I am not sure why you are working on the ABS system, did it exhibit
some sort of problem?

All I can find on a Trouble Code 30 refers to an Oxygen Sensor
fault. Specifically in the Pre-Heat portion of the Oxygen Sensor.
If that is correct, you need to replace that Sensor.

Good Luck, Bruce

yes. the abs light is on and it is an abs code 30. unfortunately, no manual
that i have seen has the abs codes in it...we got this code from the
diagnostic computer when we plugged it into the obd port on the car.

thanks.
