If the phone is paired with the Veepeak device but fails to complete connection and download data, the TSC is not communicating. The TSC will enter sleep mode after 2 hours at standstill and no longer communicate via the Bluetooth link. If the ECU is asleep, connect to an electric brake controller to trigger it to awake (status lamp on).
