5.3.6 PEPS Wake-up Functionality
The PEPS wake-up functionality can be tested using the CARS PC application running on the host PC as follows:
1. If not done already, follow the procedure detailed in 4. CARS Kit PC Evaluation Utility.
2. If not done already, follow the calibration procedure detailed in 5.3.5 Fob Calibration Process .
3. Select the desired LF antenna channel to send the LF message, as shown in the following figure.
Note:  When Antenna Channel 1 is used, ensure that the J1 jumper on the LF antenna module is set to the
inductor only (
) position. When Antenna Channels 2 through 6 are used, ensure the J1 jumper on the
LF antenna module is set to the LCR option. Note that the Ant connector number on the ATA5291 XPRO
board starts at Ant0 while the antenna channel displayed on the CARS PC application starts with Antenna
Channel 1. As a result, Antenna Channel 1 on the PC application corresponds with Ant0 on the board. This
offset count continues for all six antenna channels.
