How do you change the abs pump on a 2001 gmc jimmy
The ABS pump relay is intergrated into the EHCU (elecro-hydraulic control Unit) and it is not serviceable. If the ABS pump relay is defective, the entire control unit must be replaced.
Likely cause is an electrical problem in the EBCM. Unfortunately it is replaced w/ the abs pump as they are one unit. Very pricey!

It is not an easy job. Get amanual on your car from AUTOBOOKSONLINE.COM if you want to tackle it.
That would be best left to a repair shop. You will need a pressure bleeder.
You should go to a shop that has and ABS scanner to determine problem. May be wheel sensor or control module ...Alternatively, there may simply be air in the ABS module. If you've opened up the hydraulic lines (say, to replace a brake caliper), then the ABS module has to be purged, or the light stays on. Just open the purge port (not the bleeder valve) on the ABS unit and use the pressure side of a hand-operated vacuum pump (NOT shop air!!) to pressurize the purge port. DON'T use the vacuum side of the pump. Add brake fluid as needed during this process. Do NOT overpressurize. Just use the bleeder valve and hand pump to purge the ABS unit until no more bubbles come out of the bleeder, just brake fluid.
The ABS Sensor is located inside of the hub, which is replacable only by replacing the entire hub assembly as a unit.
You replace the brakes on an ABS S10 the same way you replace brakes on a non ABS S10.
