Reading DTCs

Read Diagnostic Trouble Codes with a single method call.

from pyudskit import UDS

uds = UDS()
result = uds.read_dtcs(0x08)
print(result["uds_bytes"])  # 19 02 08

If your ECU returns DTCs, you can decode each one:

print(uds.explain_dtc("P0301"))

Session requirements

Some ECUs require an extended session to read DTCs. Use uds.switch_session("extended") if needed.
