CONSULT-III FunctionINFOID:0000000006219954
APPLICATION ITEM
CONSULT-III performs the following functions.
HOW TO ERASE SELF DIAGNOSTIC RESULTS
“Self Diagnostic Result”
A current self-diagnostic result is displayed on CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “Self Diagnostic Result”.
“SELF-DIAG [PAST]” Return to “Self Diagnostic Result” CONSULT-III scr een by touching the “BACK” key of CONSULT-III and
select “Self Diagnostic Result” in SELECT DIAG MO DE. Touch “Erase” in “Self Diagnostic Result” mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [P AST]” is not erased, the user mode shows the system
malfunction by the illumination of the warning lamp even if the malfunction is repaired completely.
“TROUBLE DIAG RECORD”
JMHIA0949GB
JMHIA0950GB
Diagnosis mode Description
Ecu Identification Air bag diagnosis sensor unit ECU discriminated number (identification num-
ber) is displayed. Air bag diagnosis sensor unit has individual ECU discriminat-
ed number (identification 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-III
screen in real time. This refers to a malfunctioning part requiring repairs.
Refer to
SRC-22, "
DTCIndex".
Function Test CAR COMPUTER DIAG. Test result is indicated using “OK” or “NG” so that the customer recognizes eas-
ily.
Special function SELF-DIAG [PAST]
Diagnosis results previously stored in the memory are displayed on CONSULT-
III screen. The stored results are not erased until memory erasing is executed.
TROUBLE DIAG RECORD With TROUBLE DIAG RECORD, diagnosis results previously erased by a re-
set operation can be displayed on CONSULT-III screen.
SELF-DIAG RESULT [CAN] This item is displayed, but cannot be supported.

DIAGNOSIS SYSTEM (AIR BAG)
The memory of “TROUBLE DIAG RECORD” cannot be erased.
“SELF-DIAG RESULT [CAN]” Self-diagnosis result other than “SELF-DIAG R ESULT [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 illumi nates. “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 w hen 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 DT C” is displayed even if the malfunctioning parts are
checked by CONSULT-III.
Display contents of CONSULT-III Description
Air bag IGN VOLT COND
“LOW” is displayed when IGN low or high voltage is detected. If not, “OK” is
displayed.
IGN VOLT TIME Number of times of IGN low or high voltage is detected.
LOW V RECORED Number of times of IGN ON after IGN low or high voltage is detected at first.
Display contents of CONSULT-III Description
Occupant detection
system 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.
