Trouble Diagnosis without CONSULT

INFOID:0000000009269125

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-20, "Flash Code Index"

.

SRS History Check

INFOID:0000000009269126

SRS HISTORY CHECK

1. Check repair history of the SRS. If no repairs have been made perform

SRC-13, "SRS Operation Check"

.

If repairs have been made GO TO step 2.

2. Erase "SELF-DIAG [PAST]" after repair. Refer to

SRC-15, "SRS Final Check"

.

SRS Final Check

INFOID:0000000009269127

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 “SELF-DIAG RESULTS [CURRENT]”, the malfunction has not been repaired

completely or another malfunction is being detected. Perform SRS Operation Check again. Refer to

SRC-

13, "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 show 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-13, "SRS Operation Check"

.
