CONTROL AND SECURITY

UDS write, program, and actuation services are locked by default. RAW responses are available to verify the adapter's actual output.

The availability of each data point or function depends on the vehicle, ECU, protocol, and adapter used. The ELM325 is intended for J1708/J1587 and is not a replacement for a CAN adapter. Some ELM clones may offer partial compatibility.
