UI_a045_ECallSystemCheckFailed
Emergency call is not operational
What does the UI_a045_ECallSystemCheckFailed alert mean?
The cellular modem detects the emergency call (eCall) self-test did not pass. During vehicle start-up and when the drive rail is turned ON, the emergency call (eCall) system will attempt 1 self-test with 3 retries. If the 3 retries are unsuccessful, the alert will set. Since the eCall self-tests are run on each ignition, the alert may appear and disappear depending on the result of the latest self tests.
