DIAGNOSIS SYSTEM (AIRBAG)

From Diagnosis Mode to User Mode

To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, then diagnosis mode automatically changes to User mode.

SELF-DIAGNOSIS FUNCTION (Without CONSULT-III)

• The reading of these results is accomplished by “User mode” and “Diagnosis mode”.
• After a malfunction is repaired, turn ignition switch ON. Diagnosis mode returns to the user mode. At that

time, the self-diagnosis result is cleared.
