97 jeep grand cherokee abs issue
my jeep has a code 30 on the abs (pump motor circuit bad). we have done
diagnostics on the system and have come to the conclusion that the CAB is the
problem. (hotwired the pump and there's nothing wrong with it and traced and
tested all wires - again, nothing wrong). would there be anything else that
could be the cause of the problem that we may have missed or should i get the
CAB remanned and see what happens?
thanks

Before you go fixing bits...
If your ABS computer is up by the front like mine
http://revbeergoggles.com/Fixes/computer-abs.jpg
Then the connector is probably full of dirt and road salt/debris.
This will cause all sorts of problems. Including a code 30 among others.
Best to do this with the battery disconnected, but I've done my simply
by pulling the ABS fuses and relay.
Take the connector off.
Take the air filter cover off and the filter out.
(your going to use this as a sink)
Put a plastic bag in the "sink" and some news paper.
Take the ziptie off and open the shell. Knock out all the
crud that is in there.
Then with some contact cleaner, (wear gloves it's bad
on the skin and even worse on the paint) spray the
connector clean. Toothpick, cotton swaps, toothbrush.
Then take a small emory file to the contacts on the computer.
clean also with solvent, toothpicks, swabs, etc and let dry.
Apply a liberal amount of dilectric grease to the connector
(back and front, it keeps the moisture out) then reassemble
the whole thing.
I put a plastic shield over my abs computer to keep future
debris from getting in there. Seems where Jeep put the
thing is also where the hood drains and where road junk
comes in past the air box intake.

Re: 97 jeep grand cherokee abs issue
thanks...but mine is a 97 and the CAB actually screws to the bottom of the
pump/motor and isn't mounted on the fender.

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
