Started with bad #6 coil & wire, fixed that but still this.
Also I get EBCM no comm
Should that be right? I was messing around with tpms and wheel sensors and disconnect swps. All that is put back & sensors are installed and learned and seems ok.
Learning this tech2 so bear with.

Whenever u get the dreaded EBCM no COMM message it is usually a bad connection at the ECM or BCM side ,
pull the fender well inner liner and pull off the connectors off the ECM , clean them with Contact cleaner , dont use anythng else to clean as the solvents might leave a residue or react badly with the metal of the connector
test and see if you have communication, if so clear the codes and see if they come back ..
If u still have no comm hen pull off the BCM side next and do the same ..
these two connectors are usually the problem
as far as your codes , I think the only real one is the EVAP code but you wont know till you clear up the EBCM issues...
