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 CARS Kit PC Evaluation Utility.
2. If not done already, follow the calibration procedure detailed in Fob Calibration Process .
3. Select the desired LF antenna channel to send the LF message (see the following figure).
   Note:

   • When using the ATA5291-XPRO and antenna channel 1, ensure that the J1 jumper on the LF antenna module is set to the inductor () only position. When using channels 2 through 6, ensure the J1 jumper on the LF antenna module is set to the LCR option.
   • When using the ATA5293-XPRO and antenna channel 1, the X-10013-002 antenna is required. When using antenna channels 2 through 5, the X-10013-003 antenna is required; channel 6 is not used within the PC application.

   

4. Select the desired “LF Antenna Current” from the drop-down list.
5. Enter the polling interval value in milliseconds (for example, 1000, meaning the LF wake-up signal is transmitted every one second).
   Note: 500 ms is the minimum allowable interval.
6. Check the “Polling” check box to enable polling and ensure that the LEDs on the fob blink each time the new wake-up signal is received.
7. Type in a new Vehicle ID (for example, 887766), click on any other field within the window and ensure that the LEDs on the fob no longer blink. This demonstrates that the fob only wakes up for the vehicle it was paired to.
8. Type in the original Vehicle ID – 667788.
9. Uncheck the “Polling” check box to disable polling.
