< SYSTEM DESCRIPTION >

DIAGNOSIS SYSTEM (AIR BAG)

The memory of “TROUBLE DIAG RECORD” cannot be erased.

• “SELF-DIAG RESULT [CAN]”

Self-diagnosis result other than “SELF-DIAG RESULT [CAN]” is erased when touching “Erase”.

SPECIAL FUNCTION

CAUSE OF WARNING (AIR BAG)

This item indicates IGN low or high voltage condition.
The air bag warning lamp blink in user mode when the battery voltage is lowered to the voltage value (less
than 9 V or highroad to the voltage value (more than 16V) at which the SRS cannot be operated normally. The
air bag warning lamp turns OFF after the battery voltage returns to normal status after blinking. 
In such a case, the DTC memory is not performed and changing to the self-diagnostic mode by IGN operation
cannot be performed while the air bag warning lamp illuminates. “NO DTC” is displayed even if the malfunc-
tioning parts are checked by CONSULT-III.
This function records the following items.

CAUSE OF WARNING (OCCUPANT DETSCTION SYSTEM)

Detection status and detection record is displayed when air bag warning lamp blinks due to occupant detec-
tion function stop. Change to trouble diagnosis mode by ignition switch is not possible while warning lamp is
blinking due to occupant detection function stop. “NO DTC” is displayed even if the malfunctioning parts are
checked by CONSULT-III.

FUNCTION STATUS

• “ON” or “STOP” is displayed according to occupant detection status that 

is recognized by occupant detection system control unit.

• “STOP” is displayed when occupant detection function is stopped, if not, 

“ON” is displayed.

STOP DETECTION

Displays number of times occupant detection function stop which is detect-
ed by occupant detection system control unit is displayed.

DETECTION RECORD

Displays number of times of IGN ON since first detection of occupant detec-
tion function stop is displayed.
