Self-diagnostic Function

Malfunction detection function

•  The malfunction detection function detects malfunctions occurring in the Bluetooth system (hands-free telephone (HF/TEL) system).

Memory function

•  The memory function converts a malfunction detected by the malfunction detection function to a DTC and stores it. The error currently occurring is stored as a present malfunction. Up to three DTCs (with audio unit), or six (with car-navigation unit) can be stored as a present malfunction. The error that has previously occurred is stored as a past malfunction. (with car-navigation unit) The DTCs, together with the number of times the ignition switch has been turned off after the occurrence of an error (maximum of 255 times), are stored as a past malfunction. (with car-navigation unit)
