11. Press the "DISP TEXT" switch again to display the "iPodS" (iPod® software version). "FFFFFF" is displayed when communication signals between the audio unit and iPod adapter include a malfunction.
12. Press the "DISP TEXT" switch again to display the "iPodH" (iPod® hardware version). "FFFFFF" is displayed when communication signals between the audio unit and iPod adapter include a malfunction.

Finishing Self-diagnosis Mode

Self-diagnosis Mode is canceled when turning ignition switch OFF.

The on board diagnosis has 3 modes: the self-diagnosis mode that performs the trouble diagnosis, the speaker adaptation data deleting mode and the hands free phone system initialization mode.

SELF-DIAGNOSIS RESULTS

Self-diagnosis mode reads out the self-diagnosis results and indicates DTC on the audio screen.

Note. Error count is read out simultaneously when reading out the DTC name. The errors are read out continuously when some errors occur at the same time. The DTC displays are combined and displayed. For example, DTC 01100 is displayed when DTC 01000 and DTC 00100 are indicated at the same time.

SELF-DIAGNOSIS RESULTS

The Details of Error Count

The error count guides "0" when the error occurs. The next time it counts up "1" if it is normal with the ignition switch ON. It continues the count up unless the initialization of hands free phone system is performed.
