0 votes
2011 chevrolet equinox. Had to replace battery in vehicle after being dead for a few days. while trying to reprogram the unit (evo all) using i cant get the yellow lamp to flash. when i plug the 4 pin connector in it alternates between blue and red only. If i cycle the key a few times the yellow will light up so i know it is operational but wont light when 4 pin is connected. All worked well until battery died. Any ideas if the module needs replacing.

Must have a very old firmware in there. Lots of update were made in GM since the last few years. Maybe tech support guys can take a look at older guides for programming ?

What's the service number on the unit ?
