Turn ignition switch ON. Check the blinking pattern of air bag warning lamp.
There are 2 blinking patterns for the air bag warning lamp as per the following items.
• Front air bag system: 3 second blink followed by a 0.5 second blink repeated.
• Side air bag system: Two 1.5 second blinks followed by a 0.5 second blink repeated.

Side air bag system
How to Erase Self-diagnostic Result
After a malfunction is repaired, turn the ignition switch OFF for one second or more, then turn ignition switch
ON. The diagnosis mode returns to the user mode. At that time the self-diagnostic result is cleared.

CONSULT Function
INFOID:0000000009649846
APPLICATION ITEM
CONSULT performs the following functions.
CAUSE OF WARNING LAMP
The SRS air bag warning lamp blinks when the ignition voltage is a voltage value (9V or less, or 16 V or more)
at which the SRS air bag cannot operate normally. After blinking, if the ignition voltage returns to normal, SRS
air bag warning lamp turns OFF.DTC memory is not performed while the abnormal ignition voltage is detected.
The mode cannot be switched to trouble diagnosis mode when the ignition switch is operated.“No DTC” is dis-
played when checking “Self-diagnosis result” using CONSULT.
NOTE:
• SRS air bag warning may blink when the condition is out of detection area* of the satellite sensor in door.
The system is normal if SRS air bag warning lamp turns OFF after the condition returns within detection area
of the satellite sensor in door.
• SRS air bag warning lamp blinks when the zero point reset is incomplete after replacing the occupant detec-
tion system control unit. (SRS air bag warning lamp turns OFF after the zero point reset is complete.)
• *: Pressure inside of door is excessively low and air bag system cannot be operated normally (example: alti-
tude is approximately 4,000 m or more).

Diagnosis mode
Description
Ecu Identification
Air bag diagnosis sensor unit ECU discriminated number (identification number) or part num-
ber is displayed. Air bag diagnosis sensor unit has individual ECU discriminated number
(identification number) or part number based on model and equipment.
Self Diagnostic Result
The current self diagnosis results (also indicated with the number of air bag warning lamp
blinks in the diagnosis mode) are displayed on CONSULT screen in real time. This refers to
a malfunctioning part requiring repairs.
Refer to
TROUBLE DIAG RECORD
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation
can be displayed on CONSULT screen.
SELF-DIAG RESULT [CAN]
This item is displayed, but cannot be supported.
Cause of Warning Lamp
It displays the cause of warning lamp illumination that is not recorded in memory.

Actions by worker
IGN VOLT COND
The ignition voltage recognized by air bag system (air bag
control unit and occupant detection system control unit) is
displayed or a message stating that condition is out of de-
tection range of satellite sensor in door is displayed.
• OK: Normal
• LOW: The ignition voltage is low, high, or out of detec-
tion range of satellite sensor in door
Perform the check at an altitude of 4,000 m or
less.
• Check battery voltage if the ignition voltage
status is displayed as “LOW”.
• Check battery voltage if the ignition voltage
status is“OK” and the number of times detect-
ed is 1 or more. This is because an ignition
voltage error may be detected in the past.
NOTE:
If battery voltage is normal, the cause may be
that out of detection range of satellite sensor
in door is detected.
IGN VOLT TIME
Total number of times is displayed, summing up the num-
ber of times ignition voltage error is detected and the num-
ber of times that out of detection range of satellite sensor
in door is detected.
(Detection record is erased and counter returns to “0” by
“ERASE MEMORY” in “Self-diagnosis results” using CON-
SULT.)
LOW V RECORED
Number of times ignition switch ON is displayed after igni-
tion voltage error or out of detection range of satellite sen-
sor in door is detected.
(Detection record is erased and counter returns to “0” by
“ERASE MEMORY” in “Self-diagnosis results” using CON-
SULT.)
