I let a friend borrow my FSM or I would just look it up. Got a service ABS light today. Which pins do I jump and what buttons do I press to get the brake codes? It's a 92.

Jump pins A & G, A is on the bottom row, far left, G is on the top row far right.

The "Fuel reset" bottons run the modules up & down

"Gauges and Trip Odo" moves thru the module to view codes

"Fuel info" & "Eng Met" moves thru those codes.

9.1 is the ABS

Andy, seems that the "Tech Library" has disappeared.

EBCS Error Codes - Module 9.1

yea, it had a major bug... I need to resurrect it in some form or another.

I never really liked how it worked. Perhaps time to do something better.

Looks like error 25, well H25 since the car wasn't running. I just replaced that whole bearing hub less than 6 months ago. Maybe it's just a fluke. I'll have to keep an eye on it when I drive it home tonight and see if it comes back.

Remind me again what module 4 is? I got an H22 and H72 out of it as well.

Module 1- CCM
4- ECM
9- EBCM

25 is Intake Air Temp High
72 is Gear Selector Switch Error

I'd clear them and not worry about em.

Yeah those codes could have been there for years. They certainly weren't current. I don't think the ABS code is anything more than a fluke either. Just kinda made me wonder since I had just replaced the calipers and flushed the whole system. Kinda a "you gotta be kidding" moment.

Module 4 is the ECM...

the ABS is hard to predict. Reset it, test it again. it could be a bad sensor. Is H25 a front or rear issue? The sensor is in the front, on the upright in the rear.

Left front wheel speed sensor problem is what it supposedly means. As you said the sensor is in the bearing / hub assembly. I had replaced that about 6 months or so ago and the new part is a Timken so I would hope it's not bad. I cleared the code and drove it home with no problems and the code did not come back. I feel like it was just one of those occasional little flukes that are bound to happen on a 20 year old car.

Thanks all for the information. It would figure that my FSM sits on the shelf gathering dust for probably 6 years and the one time I need it I've loaned it out to a friend.
