Found out from my mechanic that my 02 Vert's ABS pump needs replacing and usually when the pumps go you have to also replace the module. New pump and module with labor will cost me almost 4,000. Can you and where can you get a refurbished pump. I found the module on ABSFIXER but can't seem to locate a pump.

 

Not a frequent failure, typically....it's just the ebcm that goes. Sometimes, just exercising the pump will do it. What codes did it throw, and what are the symptoms.

here's a simple fix you can try:for a " Service ABS/Service Traction Control" DTC code C1243-C or H

When the car is started the system turns the (BPMV) ABS pump on and off and if the voltage read out is not high enough, code C 1243 is set and you get the messages. If you do not have the interface connector for the EBCM, pull the module away from the pump section. I measured the resistance of the pump motor from pin number 8 ((from left to right) (it is the first pin on the right hand connector) to the frame ground and it was in spec according to the manual. When a pump is new or has been rebuilt it requires some break in period. If a pump has not been used for some time it will also draw more current due to sediment build up and not being exercised. With this in mind I pushed a wire into pin 8 and ran it over close to the positive post of the battery so I could exercise the pump manually. The pump came on the first time I touched the positive post but sounded sluggish. I exercised the pump about 6 more times for about 15 to 20 seconds at a time. I put the EBCM back on the pump section & cleared the codes. If you try this use a heavy gauge wire and be aware the wire may get warm as you touch the battery. The pumps on these ABS units are most likely not broken in since they hardly run during the life of the car.

The EBCM is on the left with the large wire harness coming into it and the sticker on top. The Brake Pressure Modulator Valve (BPMV) is on the right with the brake lines coming out.

 

Mechanic told me that they tried to start the pump manually and it would not start. Power is going to and from the pump.

 

Many have been down this road before, so nauturally, they will ask questions.....to try to keep you from getting stuck by a shop.

It really helps if you disclose everything up front.

 

Lucky, disclose what up front? I do not understand your message. I trust this mechanic and he tells me the pump is gone and usually when the pump goes you have to replace the module too simple.

 

So maybe from some of the post here that all I need to do is replace the module.

 

I found ABFIXER that will refurbish my module for 150.00 purchase a refurb one for 300.00 and from Corvette Specialties a used pump for 400.00.

 

Without the trouble codes, all we can do is speculate. What codes are you getting?

 

in case you don't have this guide, here's how:

with the key in the on position, but the engine not running
push and release the reset button until all messages cleared
next push and HOLD button #4
next push and release button #1 four times while holding button #4
When first engaged the on-board diagnostics go into an "automatic" mode which shows all parameters: PCM-TCS-RTD-BCM-IPC-radio-HVAC-LDCM-RDCM-SCM-RFA. If there are no problems, you will see "no more codes" on the ICP display. The computer will show two kinds of codes, "current" and "history," designated "C" or "H". A current code indicates a malfunction is present in the system whose module is displaying data. A history code indicates a past problem. When the screen displays "manual diagnostics," select the desired module by pressing the "options" button to go forward or the "trip" button to go back. Press "gages" to go forward or "fuel" to go back. To exit the diagnostic mode at any time, press "E/M "
THEN...let's see what codes you have relative to your problem...regardless, I suggest that:
before you replace that BPMV (abs pump module) I would have abs fixer repair your EBCM 1st...then, test the system, and if that solves your problem, you are money ahead...if not, THEN replace the BPMV..
