Вот нарыл из сервис мануала, Jeep правда другой но алгоритм почти такойже.
When a valid key is received from the FOB, the security module sets the ignition position to START/CRANK
The Totally Integrated Power Module (TIPM) then turns the ignition status to START/CRANK.
If conditions are correct to start, the Powertrain Control Module (PCM) turns On the high side of the starter relay and turns the ANL_LFT signal (the crank hold signal) to True. If the TIPM is still in START/CRANK, and the ANL_LFT signal is True, then the TIPM turns On the low side of the relay and the engine will start cranking.
Once the engine is started, the PCM deactivates the double start over ride. The TIPM will then deactivate the starter either when the engine starts or the maximum time has been reach for the tip start (10 sec for gas and 25 sec for diesel).
The security module changes the ignition position to RUN if the start type is TIP start or the 2 second time expires or the PCM indicates the vehicle is not in park or neutral. The engine can be manually shut down by the driver with speeds over 5 MPH (8 KPH) in any gear.
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 PRESSED
• THE HAZARD SWITCH IS PRESSED
• NOT IN PARK OR NEUTRAL
• VEHICLE SPEED HIGH
• VTA ALARM TRIGGERED
• PANIC MODE ACTIVATED
• BATTERY VOLTAGE HIGH
• BATTERY VOLTAGE LOW
• LOSS OF BATTERY VOLTAGE
• MIL ON
• LOW OIL PRESSURE
• COOLANT TEMPERATURE HIGH
• CRANK NO START
• RKE OFF MESSAGE
• VEHICLE NOT CONFIGURED
• HOOD SWITCH NOT INSTALLED OR INOPERATIVE
• NO AUTOMATIC TRANSMISSION
• INVALID KEY
• IGNITION SNA
• IGNITION NOT IN LOCK
• VEHICLE IN SHIPPING MODE
• VEHICLE NOT PROGRAMMED
Since the horn sounds and the parking lights flash, this verifies the TIPM is receiving the CAN BUS message from the security module. It also verifies the RF signal for Remote Start from the FOBIK to the module is operating correctly.
1. Using the scan tool, check the Remote Start inhibits of the TIPM or any ACTIVE DTCs listed in all modules. The inhibits are listed above.
