The 1100X/F-GM interface module is used when installing remote start products in GM vehicles equipped with a factory immobilizer. The 1100X/ F-GM allows for easy interfacing between the remote start and the factory immobilizer, while maintaining the integrity of the OEM system. The factory transponder-based anti-theft system uses a small electronic chip hidden in the key to send a code to the vehicle’s transceiver when the ignition is energized. The key must be placed in the ignition and turned to the RUN position. This energizes a coil surrounding the key, which in turn energizes the chip, which sends a code to the vehicle. If the vehicle does not detect the code being sent, the vehicle will start and then immediately shut off or will just crank, and the anti-theft light will flash. The 1100X/F-GM provides a valid code to the vehicle whenever it is remote started, but does not affect the immobilizer system during normal vehicle operation; the immobilizer system remains fully functional.

STEP 1: SELECT INSTALLATION MODE
Complete the wire connections to the vehicle and to the remote starter/alarm system. Connect all harnesses including the 4-pin power harness. The module LED will now flash green intermittently. (Note: if this condition is not present, your module may need to be reset to the factory default).
1. Press and release the programming switch to select installation mode.
Press the switch to alternate between the two modes (only standard mode should be used).
1 flash, pause, I flash, pause = (This mode is not used) flashes, pause, flashes, pause = Standard installation mode.
- When installation mode is selected, press and hold the programming button until the LED displays a solid green light for two seconds. Your installation mode is now programmed. Please proceed to step .
STEP 2: PROGRAMMING PROCEDURE
1. Insert the key into vehicle ignition.
- Start the vehicle and wait for the module LED to illuminate green for seconds. (Note : If module LED remains illuminated red after 10 seconds elapsed time, turn the key to “OFF” and repeat programming procedure)
- Programming has been completed.
LED DIAGNOSTICS
1. When the remote starter is engaged, the LED will flash green to indicate the module has been correctly programmed. If the LED remains illuminated red, the device is incorrectly programmed.
FACTORY RESET
1. Unplug all connectors from the module.
- Press and hold the programming button while inserting the
4-PIN standard connector.
- The LED will begin to flash red. Immediately release the programming button. The LED will turn on solid for seconds to confirm module reset
