Trouble Diagnosis without CONSULTINFOID:0000000009460726
DIAGNOSIS MODE
NOTE:
Diagnosis Mode can not be entered if a malfunction is not detected in User Mode.
1. Turn ignition switch ON.
2. After AIR BAG warning lamp lights for 7 seconds, turn ignition switch OFF within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two more times (3 times total).
5. Turn ignition switch ON.
SRS is now in Diagnosis Mode. Refer to SRC-23, "Flash Code Index"
.
SRS History CheckINFOID:0000000009460727
SRS HISTORY CHECK
1. Check repair history of the SRS. If no repairs have been made, perform SRC-15, "SRS Operation
Check". If repairs have been made, GO TO step 2.
2. Erase "SELF-DIAG [PAST]" after repair. Refer to SRC-17, "SRS Final Check"
.
SRS Final CheckINFOID:0000000009460728
DIAGNOSIS MODE
1. Connect CONSULT.
2. Confirm that zero point reset of OCS is complete.
3. If no DTCs are detected on “SELF- DIAG RESULTS [CURRENT]”, repair of SRS is completed. Go to step
4.
If any DTCs are detected on “SEL F-DIAG RESULTS [CURRENT]”, t he malfunction has not been repaired
completely or another malfunction is being detected. Perform SRS Operation Check again. Refer to
SRC-15, "SRS Operation Check"
.
4. Touch “ERASE”. NOTE:
Touching “ERASE” will clear the SRS memory of the malfunction (“SELF-DIAG [PAST]”). If “SELF-
DIAG [PAST]” is not erased, User Mode may s how the previous system malfunction even if the
malfunction has been repaired completely.
5. Check that no malfunction is detected in “SELF-DIAG [PAST]”.
6. Exit Diagnosis Mode and disconnect the CONSULT.
7. Perform SRS Operation Check. Refer to SRC-15, "SRS Operation Check"
.
CONSULT Function (AIR BAG)INFOID:0000000009460729
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
CONSULT can display each diagnostic item using the diagnostic test modes shown following.
Diagnostic Test Mode Diagnostic Item Description
Self Diagnostic Result SEL F-DIAG RESULT [CURRENT]A current Self-diagnosis result (also indicated by the number of
warning lamp flashes in the Diagnosis mode) is displayed on the
CONSULT screen in real time. This refers to a malfunctioning part
requiring repairs.
Data Monitor DATA MONITOR Displays air bag diagnosis sensor unit input/output data in real time.
Ecu Identification ECU DISCRIMINATED NO. Air bag diagnosis sensor unit ECU discriminated number (identifica-
tion number) or part number is displayed. Air bag diagnosis sensor
unit has individual ECU discriminated number (identification num-
ber) or part number based on model and equipment.
Trouble Diagnostic Record TROUBLE DIAG RECORD [PAST] With TROUBLE DIAG RECORD, diagnosis results previously
erased by a reset operation can be displayed on the CONSULT
screen.
