2011 Silverado 1500 transponder bypass

0 votes
I am having trouble getting the TB-GM2 programmed that was included in the THAR-GM2 harness.  I've followed the instructions numerous times but the bypass witll not program.  The only part of the step that I'm having inssues with is the 5 seconds for remote start.   I have to hit the start button on the Compustar remote just before cutting the ignition off to get it under 5 seconds.  I notice that under the connection diagram 6 the it doesn't show the TB-GM2 wired to the EVO-ALL.  Can this be done without using the TB-GM2?

 

Thanks

Mike

Hi Mike,

The TB GM2 is optional. You can still use the EVO ALL as a bypass if you do connection 6. Connection 6b is for the TB. If you use the vehicle on a regular basis then the TB is not necessary, its only installed on vehicles that are not used on a regular basis to prevent a power drain on the vehicle. If you pass the 5 seconds allowed then for sure it won't program. Some remote starters will take more than 5 seconds to power ignition, then you have to time it so you activate the remote starter just a little ahead.
