CONSULT Function

INFOID:0000000007564581

APPLICATION ITEM

CONSULT performs the following functions.

CAUSE OF WARNING LAMP ILLUMINATION

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 displayed 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 number
is displayed. Air bag diagnosis sensor unit has individual ECU discriminated number (identifica-
tion number) or part number based on model and equipment.

Self Diagnostic Result

• Self-diagnosis result is displayed.

Refer to

SRC-19, "DTC Index"

.

• “No DTC” is displayed when repair is completed by part replacement or other operations.
• “SELF-DIAG RESULT [PAST]” is displayed until “Erase” is performed.

CAUTION:

When “No DTC” is displayed after repair, always perform “Erase”. If this is not done, SRS
air bag warning lamp remains blinking when user mode is resumed.

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.

Display content

Actions by worker

IGN VOLT COND

The ignition voltage recognized by air bag system (air bag
control unit) is displayed or a message stating that condi-
tion is out of detection 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.

LOW 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.)
