EWS3.3 wire testing.
Grab your voltmeter and check each EWS wire. Is fuse 11 okay? Check for voltage drop across it. It's where my X5 is having amp draws of 500 mA! Yet, the module tests okay and responds to scanning. Two items may have faults: starter or transmission shift inputs. Knowing when it should and shouldn't have power is great information.
