Transmitter Approach Detected - Driver Side	00 - None 01 - Key Fob 1 02 - Key Fob 2 03 - Multiple Key Fobs	Identification of Key Fob/ Transmitter as the customer gets near the left side of the vehicle that enables the vehicle lights to turn on. The vehicle will open without any button presses
Transmitter Approach Detected - Driver Side	00 - None 01 - Key Fob 1 02 - Key Fob 2 03 - Multiple Key Fobs	Identification of Key Fob/ Transmitter as the customer gets near the left side of the vehicle that enables the vehicle lights to turn on. The vehicle will open without any button presses
Transmitter Approach Detected - Rear	00 - None 01 - Key Fob 1 02 - Key Fob 2 03 - Multiple Key Fobs	Identification of Key Fob/ Transmitter as the customer gets near the tailgate of the vehicle that enables the vehicle lights to turn on. The vehicle will open without any button presses.
Driver Door Ajar Switch	Active/Inactive	This parameter indicates that the driver door is ajar; it is open, but the safety latch is engaged.
Driver Door Open Switch	Active/Inactive	This parameter indicates that the driver door is more than just ajar, it is open.
Driver Door Unlock Switch	Active/Inactive	This parameter indicates if the driver door is locked or unlocked.
Exterior Driver Door Handle Switch	Active/Inactive	This switch begins the challenge and response to determine if the door should be unlocked. If the vehicle responds correctly to the challenge, the door will be unlocked or unlatched.
Exterior Driver Door Handle Proximity Sensor	Active, Inactive, Fault	This is a capacitive proximity sensor on the exterior of the driver door handle. It allows the user to lock the door by pressing a small rectangle on the outside of the door handle if a key is detected leaving the vehicle.
Passenger Door Open Switch	Active/Inactive	This parameter indicates that the passenger door is more than just ajar, it is open.
Passenger Door Ajar Switch	Active/Inactive	This parameter indicates that the passenger door is ajar; it is open, but the safety latch is engaged.
Exterior Passenger Door Handle Switch	Active/Inactive	This switch begins the challenge and response to determine if the door should be unlocked. If the vehicle responds correctly to the challenge, the door will be unlocked or unlatched.
Exterior Passenger Door Handle Proximity Sensor	Active, Inactive, Fault	This is a capacitive proximity sensor on the exterior of the driver door handle. It allows the user to lock the door by pressing a small rectangle on the outside of the door handle if a key is detected leaving the vehicle.
Left Rear Door Ajar Switch	Active/Inactive	This parameter indicates that the driver's side rear door is ajar; it is open, yet the safety latch is engaged.
Exterior Left Rear Door Handle Switch	Active/Inactive	This switch begins the challenge and response to determine if the door should be unlocked. If the vehicle responds correctly to the challenge, the door will be unlocked or unlatched.
Right Rear Door Ajar Switch	Active/Inactive	This parameter indicates that the passenger's side rear door is ajar; it is open, yet the safety latch is engaged.
