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".

2. Touch “TROUBLE DIAG RECORD”. NOTE:
With “TROUBLE DIAG RECORD”, di agnosis results previously erased by a reset operation can be
displayed.
3. Diagnostic code is displayed on “TROUBLE DIAG RECORD”.
4. Touch “PRINT”.
5. Compare diagnostic codes to "CONSULT-III Diagnos tic Code Chart ("SELF-DIAG [PAST]" or "TROUBLE
DIAG RECORD")".
6. Touch “BACK” key of CONSULT- III until “SELECT SYSTEM” appears.
7. Turn ignition switch OFF, then turn off and disconnect CONSULT-III, and both battery cables.
8. Repair the system as outlined by the “Repair orde r” in “Intermittent Malfunction Diagnostic Code Chart”,
that corresponds to the self-diagnostic result. For r eplacement procedure of component parts, refer to the
Removal and Installation procedure for the appropriate component.
9. Go to "DIAGNOSTIC PROCEDURE 3", for final checking.

WARNING:
• When servicing the SRS, do not work from directly in front of air bag module.
• Always place air bag module with pad side facing upward.
CAUTION:
• Before servicing the SRS, turn ignition switch OFF, discon-
nect both battery terminals, then wait at least three minutes.
• Do not attempt to repair or replace damaged direct-connect
SRS component connectors. If a driver air bag direct-connect
harness connector is damaged, the spiral cable must be
replaced.
• Do not insert any foreign object s (screwdriver, etc.) into air
bag module or harness connectors.
• Do not disassemble air bag module.
• Do not expose the air bag module to temperatures exceeding
90° C (194° F).
• Replace the air bag module if it has been dropped or sus-
tained an impact.
• Do not allow oil, grease or water to come in contact with the
air bag module.
1. Place the steering wheel in the straight ahead position.
2. Disconnect the negative and positive battery termi nals, then wait at least three minutes.
