Self-Diagnosis FunctionINFOID:0000000001328794
The followings are diagnosis functions performed by TEL adapter unit.
 Performs the unit self −diagnosis and antenna diagnosis, and informs results with the indicator and voice
guidance.
 Informs vehicle speed pulse count from the time of key switch ON with voice guidance, and enables to check
vehicle speed signal.
 Outputs voice giving to microphone with speaker, and enables to check microphone function.
OPERATION PROCEDURE
1. Start the engine.
2. Press and hold switch for 5 seconds or more.
 This allows the indicator to blink concurrently with voice guidance outputs, and determines if there is any
current error in the state of blinking.
