FM ADVANCED FIRMWARE
INSTALL TYPE 2:
The installation type 2 is a result of long term fi eld testing with logic analyzers and aftermarket products permanently installed in multiple vehicles. During
the researches, it’s been possible to identify strong bouncing frequencies received through the immobilizer antenna during remote start due to many different
types of products. The most common products to affect the immobilizer communication are; Blue Tooth devices, cellular hands free kits, cell phones, wireless
internet, Two way aftermarket alarm/starters (depending on RF timing), remaining key in the ignition barrel are all examples of interfering devices. Our
researches concluded that the PATS immobilizers systems using the D type connector were a lot more sensitive to external RF than any other PATS receivers.
For this reason, from now on, we recommend you to use the install type 2 on any vehicle equipped with the D type connector PATS immobilizer. Alto we list
only the D type vehicles for type 2, it is recommended to use the type 2 installation method for vehicles equipped with many RF devices or if the vehicle owner
intends to remote start the vehicle with a key remaining in the ignition barrel. (RF collisions may result into intermittent remote start failure since the module
protection will interrupt communications upon collision detection to avoid sending any corrupted informations to the vehicle)

INSTALL TYPE 3:
On only few vehicles the PATS immobilizer module is powered on constant 12 Volts instead of being powered on ignition. Since all the other vehicles PATS
systems are powered on ignition, the ignition signal is used to synchronize the immobilizer challenge/communication. On the PATS systems powered on 12
Volts, a learning error will occur due to the wrong communication timing. This will prevent the module from learning the vehicle and the module LED will start
blinking Red.
We recommend to correct the vehicle circuitry by changing the PATS power source to an Ignition power source instead of constant 12 Volts. A fuse should be
used as recommended in the install schematic.
The vehicle will properly start using a key or the remote starter once this modifi cation is performed to adapt to the normal PATS initialization timings.
The modifi cation have to be secured and left permanent in the vehicle.

ADVANCED DIAGNOSTIC
Did you know the Firmware is monitoring the entire module learning process and records everything in its EEPROM?
Exactly, as soon the module is connected to the vehicle it starts monitoring and recording all its I/O’s (same as an airplane black box). The information can be
extracted from the module and sent to your technical support team for advanced debugging at any required time.
The information recorded is:
• Install Type
• 1st key code
• 1st ignition cycle ON position timing
• 1st ignition cycle OFF position timing
• 2nd key code
• 2nd ignition ON position timing
• 2nd ignition OFF position timing
• Any immobilizer communication collision
• RS232 communications
• Vehicle unlocking its programming
• Module key code sent to vehicle and validated or rejected
• Spikes on the ignition wire
• Cloned keys detection
• Protected memory buffer for module key code recovery even after module is re-fl ashed and a factory reset is been performed.
• RX/TX inversion detection and protection
• Installation mode, fi rmware, hardware informations
• Advanced recording routine for emergency key code cracking
• Complete encryption recording and advanced anti-collision protection

THE ADVANTAGES:
The FM Firmware is the most advanced TI solution available yet. The module EEPROM protected area ensure you will never use more than one key memory
bank in the vehicle ECU. If it’s ever needed to reset and reprogram a module due to a system upgrade, the FM Firmware will give you the ability to proceed
without the need of two vehicle keys.
The
ADVANCED DIAGNOSTIC
feature is a real install asset as it permit any technical support staff to see exactly what happens in the vehicle. The information
retrieved is an undisputed time saver and the quickest solution fi nder available in the industry.
