Electronic traction control. Yours may have rear TC but it should not have four wheel TC. When the ECU detects a spinning wheel from ABS sensor signal. It applies the brake to that wheel to send drive to the wheel with grip. Four wheel TC came in from 1999.
Wammers, installed the plug, turned on the ignition and ran for about 45 seconds and shut off.

Don't know. I mentioned it because of the pedal going to the floor and apparently that was what happened. Only read about it though.

If you've tried 2 pumps already a replacement brake modulator seems the next obvious step. Pity you're not closer as I have one in my shed.
Grrrrrr, good morning! I'd like to purchase that modulator in your shed. I'll pay for shipping!
