I guess I'd look at the ABS controller wiring ... under the hood driver's side on the ABS
pump/controller assembly. You should get a copy of the Bentley's or failing that a copy of at least a Chilton's for the wiring diagrams.
The dealer (or a well equiped independent) can test the ABS controller ... there is a procedure outlined in the Bentley's. Here's an excerpt from the procedure for the cluter illumination (sounds like your DTC to me)
J104 is the ABS controller
<begin clip>
If ABS warning light does not come on, check voltage of electrical system and test wiring from terminal 32 of ABS control module -J104- to instrument cluster for short circuit to Ground (GND).
- The ABS warning lamp does not switch off after 2 seconds. The red "brake system malfunction" symbol lights up after 2 seconds. Check wire from terminal 32 of ABS control module -J104- to instrument cluster for short circuit to B+ and open circuit.
- Are both the vehicle voltage and the wiring from terminal 32 of ABS control module -J104- to the instrument cluster OK? Malfunction in instrument cluster. <end clip>

Dealership
I just went to the dealership and told them my problem and they said the problem is the ABS Hydraulic unit and not the ABS ecu. They had one in stock and showed me the part and it was the hydraulic unit. I was hoping that fixing the ecu would solve the problem since taking out the ecu is easier than taking out the hydraulic unit and does not require bleeding the system.
