⚠ The scanner allows to use any poll type! Know what you do!

The OBD2 PID scanner performs a series of OBD/UDS requests for a range of PIDs and displays the results. Only PIDs with positive results (responses) will be shown in the results.

Enter all values hexadecimal (case irrelevant). Default RXID is TXID+8, try RXID range 500-7FF if you don't know the responding ID. To send broadcast requests, set TXID to 7DF and RXID to 7E8-7EF. The PID range must match the poll type PID constraints (8/16 bit).

Scan results will be shown automatically when the scan has been completed. Scanning a large range of PIDs may take some time, to get intermediate results, click "Status". You can also start the scan, do something else and return to this page later.

Notes: to avoid clashing of scan polls with vehicle polls, use the scanner only with the vehicle module NONE. The CAN bus to use needs to have been started in active mode. The scanner does not send session or tester presence messages, if you need these, use the re obdii tester tool or the obdii canX request command.
