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.
FRONTAL COLLISION DETECTION[B1209] Driver and front passenger air bag modules are deployed. Refer to
SRS-48, "
For Frontal Colli-
sion".
SIDE COLLISION DETECTION
[B1210] Side or curtain air bag modules are deployed.
Refer to SRS-50, "
For Side and Roll-
over Collision".
