Symptom: The factory alarm is being triggered when the vehicle is being remote started.

Cause: On some remote-starters the parklight output is sent before the (-) disarm, or the (-) while running. On some newer GM vehicles the OEM alarm will trigger if the parklights are activated through data.

Solution: If the OEM alarms is being triggered (while armed) during remote-start, the parklight wire from the remote-starter should be hooked up to the vehicle directly, instead of using the GM SL to activate the parklights through data.
