I tried searching but did not find any topics helping me with this issue.

'94 SSE Bonneville 136,000 miles

I'm not sure what it is called but it is located on drivers sided below air cleaner towards front of car. I see a hose going from brake resevoir on firewall to this module. On this module there are 4 pre-bent metal hoses coming out and a bunch of wires plugged in. I noticed a nice little pool of fluid underneath this module and it is all wet with brake fluid.

Can anyone tell me what this module is?
How to go about finding where the leak is located?
What are some common things that go wrong with this module?

Thanks for the help.

That is your EBTM or ABS unit.

That is the PMV assembly. Pressure Modulator Valve for ABS and Traction (if equipped). The pump is used (round part) for traction control, the black part has all the valving (gate valves) in it, and the reservior is for traction control.

Make sure the reservior isn't leaking at the hose connection.

Bottom line is that you'll need to find out exactly where the leak is coming from.

The EBCM or EBCTM module cannot leak. It'* computer with a large connector on the end.

Clean it up and nail down the exact location of the leak. We'll let you know what'* involved in fixing it.
