THEORY OF OPERATION
For the engine to start, the Sentry Key Immobilizer (SKIM) feature of the Radio Frequency Hub (RF Hub) and the Powertrain Control Module (PCM) must successfully communicate data over the data bus. Once the RF Hub sends the message that a valid Fob-Integrated-Key (FOBIK) is being used, the PCM and RF Hub perform a "handshake" routine, encrypted with the VIN, to validate this information, and a match allows the engine to run when the ignition state transitions to Start or a remote start occurrence. The repair of this fault is determined by the ability of the RF Hub and PCM to complete a successful handshake routine over the bus.
The Passive Entry (PE) antenna units allow the transmitter within the Radio Frequency Hub (also known as the RF Hub) to communicate via Low Frequency (LF) radio transmission with a FOB with Integrated Key (FOBIK) that is located inside the vehicle or, at most, about 2 meters (6.5 feet) horizontally in all directions around the outside of the vehicle. The RF Hub uses communication through the antenna units to wake up and challenge a FOBIK that is within range in order to authenticate whether that FOBIK is valid (programmed) to the vehicle. The RF Hub communicates with the FOBIK using Frequency-Shift Keying (FSK) modulation.
Each antenna unit has two dedicated connections to the RF Hub. One connection is the LF antenna output circuit, while the other connection Is the LF antenna return circuit. These circuits to each antenna unit are a twisted pair to help reduce the potential for induced electrical interference. The RF Hub microcontroller monitors all of the antenna units and will store a Diagnostic Trouble Code (DTC) for any fault that it detects.
The hard wired inputs and outputs of the antenna units may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, the most reliable, efficient, and accurate means to diagnose the antenna units requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

When installing a new Radio Frequency Hub (RF-Hub) Module, the module is programed with universal IDs for the Tire Pressure Monitoring (TPM) Sensors. The RF-Hub Module must be programmed with the correct TPM Sensor IDs or drive the vehicle for a minimum of 20 minutes with vehicle speed greater than 32 km/h (20 mph).
The vehicle Tire Pressure Monitoring (TPM) Sensor locate process occurs after the vehicle is stationary for more than 20 min. The TPM system will determine the sensor positions while driving at speeds above 32 km/h (20 mph). This process can take up to 20 min to determine TPM Sensor positions.

The TPM Module must be programmed with the correct TPM Sensor IDs or drive the vehicle for a minimum of 20 minutes with vehicle speed greater than 32 km/h (20 mph).
Note. When this DTC is active the TPM Module will enter a deactivation mode (Winter Mode) and the TPM system becomes deactivated. If winter tires and wheel assemblies are installed no repair is required.
The Tire Pressure Monitor (TPM) Module determines the TPM Sensor positions by performing the vehicle Tire Pressure Monitoring (TPM) Sensor locate procedure. This procedure is run after the vehicle has been stationary for 20 minutes. After driving the vehicle at speeds greater than 32 km/h (20 mph) for a minimum of 10 minutes without the TPM Sensor installed, the TPM Module sends a bus message commanding the TPM telltale lamp to flash for 75 seconds. After the 75 seconds of flashing, the lamp will remain on solid and a chime will be heard. The message center will display SERVICE TPM SYSTEM for five seconds and shut off, all while the tire pressure values will be displayed as dashes. After the ignition has been cycled off and on the TPM telltail lamp will remain off, the message center will no longer display SERVICE TPM SYSTEM, and the tire pressures continue to be displayed as dashes.
The Brake Transmission Safety Interlock (BTSI) is a safety feature that prohibits movement of the shift lever out of park unless certain conditions are met. The Radio Frequency Hub (RF-Hub) controls the BTSI solenoid. The RF-Hub module will engage the BTSI solenoid when the shifter is in Park, the module detects the depression of the brake pedal and the ignition position is in Run or Start, thus allowing the transmission shift lever to move from the park position to any other position. A voltage on the control circuit, when it should be locked, can cause this DTC to set.
The Brake Transmission Safety Interlock (BTSI) is a safety feature that prohibits movement of the shift lever out of park unless certain conditions are met. The Radio Frequency Hub (RF-Hub) controls the BTSI solenoid. The RF-Hub module will engage the BTSI solenoid when the shifter is in Park, the module detects the depression of the brake pedal and the ignition position is in Run or Start, thus allowing the transmission shift lever to move from the park position to any other position.
Whenever the ignition is turned on or there is a remote start active, the RF Hub performs a self test and resynchronization routine. During the routine, the RF Hub interrogates the FOBIK for the secret key information and performs a CAN Bus message handshake with the Powertrain Control Module (PCM) to start the vehicle. The PCM must reply to the RF Hub that the secret key information matches to initiate the start sequence or this code will set.
