Looking for answers please: We replaced electronic brake control module (EBCM) on 2003 Cadillac Deville with brand new unit per Cadillac dealer service diagnosis, but after installation the Brake light, ABS light, and Traction-off light still remain on with service Power Steering light also now on. GM dealer checked calibration and confirmed it and reset lights. But all of them popped back on immediately on first start. They have no answers, does anyone else?

Then there diagnosis was wrong, take it to caddy dealer, GM dealer doesnt work on to many caddies. Even know caddy is GM, they just dont have the training for caddies

its probally the sterring wheel posision sensor thats bad

scan the codes and post them here for me to look at. Push off and warmer on the heater control panel, with the key in the on posision, it might be also off and down on the mode button. This will put it into diagnostics
