Use this to update firmware for Victron products that are updateable via a VE.Can. I know for a fact that the MQB UDS requests don't work with the PQ35 platform as I have plugged my device into a VW Scirocco and it failed to return any positive UDS responses.įor the Teensy 4 I used the TI sn65hvd230 CAN transceiver on CAN1 (pins 22 and 23). VE.Bus Quick Configure (v9010154) - For installations up to 3 Multis. I must note, on the PQ25 you most probably have a Bosch MED ECU and it's not as fast as the MQBs Continental Simos, so request poll speed might have to be lower in your case. It allows you to quickly find out trouble causes of electronically.
I then log each frame (request/response) and value. memoscan u281 code scanner is a device for reading and erasing trouble code in vehicles.
I use a simple sketch on the Teensy that print's every CAN frame it see's (from either end: car or VCDS) onto the Arduino serial monitor. When you know fault code and its description. Y splitter that connects to both devices to the cars OBD port With Car Scanner ELM OBD2, checking fault codes is just one of the MANY things you can do. Teensy 3.2 + TI sn65hvd230 CAN transceiver placed in an OBD2 connectorģ. HEX V2 used with VCDS to send requests and see realtime dataĢ.
As Tony mentioned, UDS is not easy to understand and it's not documented anywhere but it's got more enhanced data than standard OBD2 PIDs - that's why can sniffing individual PID's is the best option IMO to find what you are looking for over UDS.ġ.
