I have a 2000 buick lesabre with the power windows inop from left front switch/ mirrors inop / power door locks inop (from left front control) / power seat inop. (has memory seats)
I think I have everything needed to the ddm, and have power and ground to the door switch. I also have serial data on the data line at the ddm and power seat module as observed on the o scope. I have compared these signals to the data line at the dlc on the 4 trace they are identical. but I cannot get the modis to give me any module info from any module other than the ebcm /airbag/tpm/pcm.
my question is if the modis should be givening me info on the other modules, including the ddm. snap on web site says "body control coverage for 2000 gm"
their are no codes in any of the reporting modules. I am not familer with this system and dont like selling the wrong parts. can anyboy help ??????? please (3 days into this nightmare)
