# Peugeot 3008 II: investigating CAN control of the air-conditioning unit

> Peugeot 3008 II air conditioning unit investigates CAN control of the vehicle's climate module using brute-force frame-ID exploration. An STM32G431KB project drives the module's flaps and includes notes on its TJA1055 transceiver, sensors and actuators. The author reports testing a unit marked 9811039380.
