HOW TO CHANGE BETWEEN SELF-DIAGNOSIS MODE AND USER MODE WITH CONSULT-III
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, Diagnosis mode automatically changes to User mode.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
NOTE:
If the memory in “SELF-DIAG [PAST]” is not erased, User mode will continue to show the system mal-
function by the operation of th e warning lamp even if the malfun ction is repaired completely.
• “SELF-DIAG [CURRENT]” A current self-diagnosis result is displayed on the CO NSULT-III screen in real time. After the malfunction is
repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.
• “SELF-DIAG [PAST]” Return to the “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
• “TROUBLE DIAG RECORD”
The memory of “TROUBLE DI AG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-III)INFOID:0000000005396908
The reading of these results is accomplished using one of two modes —“User mode” and “Diagnosis mode”.
HOW TO CHANGE BETWEEN USER MODE AND SELF-DIAGNOSIS MODE WITHOUT CONSULT-
AIR BAG diagnostic mode Description
SELF-DIAG [CURRENT] A current Self-diagnosis result is displayed on the CO
NSULT-III screen in real time. This refers to a mal-
functioning part requiring replacement.
SELF-DIAG [PAST] Diagnosis results previously stored in the memory are displayed on the CONSULT-III screen. The
stored results will remain until the memory is erased.
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
SRS-6, "
Occupant Classification System (OCS)" for more in-
formation.

TROUBLE DIAGNOSIS
NOTE:
Follow the procedures in numerical order when performing repairs. Confirm whether the repair has been suc-
cessful using air bag warning lamp or CONSULT-III after each repair. If malfunction is still observed, proceed
to the next step. When malfunction has been elimi nated, further repair work is not required.
DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-III—Diagnosis Mode
1. If no DTC is detected on “SELF-DIAG [CURRENT]”, repair of SRS is completed. Go to step 2.
If any DTC is detected on “SELF-DIAG [CURRENT]” , the malfunctioning part has not been repaired com-
pletely or another malfunctioning part is being detected. Go to "DIAGNOSTIC PROCEDURE 2".
2. Touch “ERASE”. NOTE:
Touch “ERASE” to clear the memory of the malfunction (“SELF-DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [P AST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
3. Touch “BACK” key of CONSULT-III to “SELECT DIAG MODE” screen. Touch “SELF-DIAG [PAST]”.
4. Check that no malfunction is detected on “SELF-DIAG [PAST]”.
5. Touch “BACK” key of CONSULT-III until “SELECT SY STEM” appears in order to return to User mode from
Diagnosis mode.
6. Turn ignition switch OFF then turn off and disconnect CONSULT-III.
7. Go to SRS-19, "
SRS Operation Check".
DIAGNOSTIC PROCEDURE 4
Check SRS Repair History
1.CONSIDER POSSIBILITY THAT SELF-DIAGNOSTIC RESULT WAS NOT ERASED AFTER REPAIR
Check repair history of the SRS.
Have any previous repairs been made to the SRS?
Yes >> Self-diagnostic result “SELF-DIAG [PAST]” (pre viously stored in the memory) might not be erased
after repair. Go to "DIAGNOSTIC PROCEDURE 3".
No >> Go to "DIAGNOSTIC PROCEDURE 2".
DIAGNOSTIC PROCEDURE 5
Check SRS Intermittent Malfuncti on Using CONSULT-III—Diagnosis Mode
1. If diagnostic codes are displayed on “SELF-DIAG [PAST]”, go to step 4.
If no malfunction is detected on “SELF-DIAG [PAS T]”, touch “BACK” and go back to “SELECT DIAG
MODE”.
BELT TENSION SENS
[UNIT FAIL]
[B1019] Belt tension sensor is malfunctioning.
1. Visually check the wiring harness
connection.
2. Replace the harness if it has visi- ble damage.
3. Replace the RH front seat belt as- sembly.
4. Replace the RH front seat cush-
ion assembly. Do not disassem-
ble the seat cushion assembly.
5. Replace the related harness.
