The Autel TCP subscription is a paid service that provides access to online programming and other advanced diagnostic features for Autel diagnostic tools.
Error 11003 code specifically signals that the TCP subscription on the device has expired or is invalid.
This is a DoIP model. That is a DOIP platform. Diagnostics over internet protocol. Volvo and Jaguar and RangeRover are all using it now. It has a secure gateway.
You have to have an active TCP subscription to diagnose Volvo DoIP models.
Autel needs both internet connection and valid subscription to work with SPA/CMA and later Volvos.
Generic obd2 on the scanner would have read it or keep your subscription up. That’s not Autel’s fault. It’s not up to Autel, Autel just follow regulations, DOIP protocol, just buy license and work.
