Re: ABS/ESP MODULATOR PUMP

Yes. I can just ever so slightly tap that unit and the light will stay off for a while. Does anyone know what kind of codes that unit sends if it is bad?

Re: ABS/ESP MODULATOR PUMP

I scanned my G and the abs light was related to that gyroscope under the center console. I will start digging in there soon.

I think that is the Yaw sensor for ESP/ABS systems etc. Thanks for your help.
