CONSULT-III Function (AIR BAG)INFOID:0000000003775187
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
Self-Diagnosis Function (Without CONSULT-III)INFOID:0000000003775188
• The reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis
mode”.
• After a malfunction is repaired, turn the ignition s witch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.
AIR BAG diagnostic mode Description
SELF-DIAG [CURRENT] A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-III screen in real
time. This refers to a malfunctioning part requir-
ing repairs.
SELF-DIAG [PAST] Diagnosis results previously stored in the memo
ry are displayed on the CONSULT-III screen. The
stored results will remain until memory erasing is executed.
TROUBLE DIAG RECORD With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-III screen.
ECU DISCRIMINATED NO. Air bag diagnosis sensor unit ECU discriminated number (identification number) is displayed. Air bag
diagnosis sensor unit has individual ECU discriminated number (identification number) based on model
and equipment.
PASSENGER AIR BAG The STATUS (readiness) of the front passenger air bag module is displayed. The STATUS displayed
(ON/OFF) depends on the signals supplied to the occupant classification system control module and
air bag diagnosis sensor unit. Refer to
SRC-10, "
