That’s a common issue when the module is failing. Sometimes it makes the ABS pump run continually and can burn it up.

Should probably get that rebuilt sooner than later then!

I'm probably just going to get that rebuilt and replace the 2 front speed sensors that are throwing codes at the same time
You can also pull the ABS fuse in the meantime so the pump can’t run.

Are there any common grounds for the EBCM, and the 2 front wheel speed sensors? I cleaned up the EBCM ground on the frame underneath the drivers door, but wondering if theres any others?
I’m not sure about the grounds, you should be able to find a diagram. Anybody?
I don't see anything specific on the ground diagram except for the ABS pump ground that is one of the two on the body mount below the driver's door hinge. Hopefully both of those grounds were cleaned. I suspect the wheel speed sensors go through the BCM or the engine computer; not sure about which one.

Intermittent battery drain - '06
Found my battery dead down to 4v after parking for a few days. I don't drive the truck a lot so it sits for a week or more a lot, but hasn't been an issue until recently. First thing I did was change the battery. Now working with a fresh battery it happened again. I'm getting 1.1v current...

Question for here real quick. What's the best method for stopping fluid flow from the master cylinder when removing the abs pump? My EBCM screws are totally rounded. If I empty the system will I need to bench bleed the master cylinder even if I don't press the brake pedal with it empty at all? Is there anyway around having to bench bleed when emptying the system in general? Not sure if a gravity bleed would take air out of the master.
I already expect to have to use a scan tool to bleed the ABS pump after.
