1999 ABS module
Anyone know how to repair it or know where my friend can find a replacement; the JL9 ABS module that goes in a 1999 is no longer made. It also runs the traction control and ride control.
If anyone is parting out a wrecked 1999 corvette, please indicate if the JL9 part is available for sale and how many miles are on it. Thanks!

RPO code for Active Handling is not JL9. It is JL4.
Unless the cause of your problems is bad grounds (common C5 electrical problem cause), blown fuse or bad power wire to the EBCM, there are no repairs that can be made to the 97 - 2000 EBCM. If you find a used module, make certain it is the correct V code module if the car has active handling. There are 2 different EBCM's for the 98 1/2 - 2000 cars. One that is for RPO JL4 and a different one for NON JL4 cars. They are not interchangeable.
The EBCM controls anti lock brakes, Traction Control and Active handling. It does NOT have anything to do with ride control.

I see.
Then why do the following references for 99 C5's state the following:
JL4 = Control, Active Brake
JL9 = Brake system, Power, Front & Rear Disc, Anti-lock, 4 Wheel

??????
Perhaps the car does NOT have Active handling since it was an RPO.
Good luck with your search..

My only point in responding to your post is that if you are going to seek used parts for the 99 that you get the CORRECT part for the car. From mid year 1998 (beginning Dec. 15 1997) through 2000 there were 2 different EBCM's for the C5. One is for those cars that have the Active Handling RPO (Has a large V on a sticker on the body of the EBCM) and a different one for those cars that do NOT have the Active Handling RPO.
If it were me and I was seeking a used replacement I would get the GM PN off the one installed and be certain that what is purchased has a matching PN.
