There is an inhibit monitor the dealer can see with the scan tool. I didn't think any of the inhibits would let it run for a minute. They usually give one honk of the horn and no crank, or they start and shut down within about 5 seconds.
REMOTE START SYSTEM
Before attempting to diagnose a problem with the remote starting system, first be sure the starter motor and starter solenoid are working properly. The starter should operate with the use of the standard ignition key in the ignition switch. Any starter or solenoid problems must be repaired first.
Also be sure the engine will easily start and run with the use of the standard ignition key in the ignition switch. Any engine running, idling or driveability problems must be repaired first.
Also note that the remote start system will automatically be cancelled if any of the following occur:
• IF THE ENGINE STALLS OR RPM EXCEEDS 2500
• NORMAL TIME OUT RUN MODE (15 MINUTES)
• CUSTOMER MOVES IGNITION INTO RUN/START
• ANY VEHICLE DOOR AJAR
• TRUNK/LIFTGATE AJAR
• HOOD AJAR
• START COUNTER REACHED
• LOW RPM SHUTDOWN
• KEY IN IGNITION
• BRAKE APPLIED. IF THE VEHICLE IS REMOTE STARTED AND THE CUSTOMER THEN UNLOCKS AND ENTERS THE VEHICLE, THE BRAKE APPLICATION WILL NOT STALL THE VEHICLE. IF THE VEHICLE IS REMOTE STARTED AND NO ENTRY IS DETECTED, BRAKE APPLICATION WILL SHUT DOWN THE ENGINE.
• LOW FUEL LEVELS. FUEL INDICATOR ACTIVE.
• THE HAZARD SWITCH IS PRESSED
• NOT IN PARK OR NEUTRAL
• VEHICLE SPEED HIGH
• VTA ALARM TRIGGERED
• PANIC MODE ACTIVATED
• BATTERY VOLTAGE HIGH
