i bought a use one and it still do the same thing. is it anything i need to check?.
Typically, it's the accumulator that goes bad on these units. It's entirely possible that you had a bad accumulator, and that you bought a used unit that also has a bad accumulator.Does the ABS light illuminate on your dash at any time?
yes, and when the botten (2) electrical plug is hooked up one of them is running my battery down
Does the pump run at all times or what's going on there? What color are the wires at those plugs?
i just went out and checked the bottom plug is white cover with red @black wires ,the one just above it is red,brown and purple. no the pump is not running now so i left it hooked up to see if it will run the battery down .the anti-lite is going off and on again
Let's see about getting the ABS codes. Here is how to do that:
Red/blk is the pump motor connector, as far as I can tell. Schematics from those days are a little tough to read, but my guess is that you're disconnecting the pump motor and the pressure switch connectors.Without a pump motor, you won't have any assist, so it's important to find out why it's staying on. By far, the most common culprit there is the pump relay. The main and pump relay are the same part number, I would replace them both, as they are high failure rate parts.
