Hi Scott,


What is the 12 digit service number written on the back of the INT-SL+?

There is a specific firmware for these units that have trouble programming in GM.

At the moment you have firmware 3.01 in that unit.

Firmware 3.06 has the correction for GM that have trouble programming.
what is the easiest and quickest way to update the module?

If you dont own a flash-link updater, you will need to contact the people you bought the int-sl from.

Ask them to flash the GM only specific firmware.

It's firmware 0.53, released on 2010-12-28
