id0902g8440500

Note
•  For the DTC inspection, there is a method using the M-MDS and one that does not use it (on-board diagnostic test mode).
•  Because the DTCs differ if using or not using the M-MDS, perform the DTC inspection using the M-MDS method and the method not using it.
•  The DTCs are cleared if the ignition is switched off or the battery cable is disconnected.
•  When performing the DTC inspection, input all of the displayed DTCs in the Audio Repair Order Form.
•  If the malfunction persists even if the engine is switched off or the battery cable is disconnected, the DTCs are displayed again.
