CAUTION:
• Never use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-
vice Manual. SRS wiring harnesses can be identifi ed by yellow and/or orange harnesses or harness
connectors.
• Never repair, splice or modify the SRS wiring harn ess. If the harness is damaged, replace it with a
new one.
• Keep ground portion clean.
DIAGNOSIS FUNCTION
• The SRS self-diagnostic results can be read with air bag warning lamp and/or CONSULT.
• The user mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the air bag warning lamp.
• The diagnosis mode allows the technician to locate and inspect the malfunctioning part.
• The mode applications for the air bag warning lamp and CONSULT are as per the following items.

ON-BOARD DIAGNOSIS
There are two self diagnosis functions with air bag warning lamp per the following items.
•USER MODE
• DIAGNOSIS MODE
METHOD OF STARTING
• Diagnosis mode changes from user mode to diagnosis mode when changing operation is performed.
• In user mode, when SRS air bag warning lamp is not turning ON, changing to diagnosis mode by ignition
switch operation is not possible.
• In diagnosis mode, when repair is complete and system is normal, the mode changes to user mode when
ignition switch is turned from OFF to ON.
Procedure to Change Diagnosis Mode
1. Turn ignition switch from OFF to ON.
2. SRS air bag lamp turns ON for 7 seconds and turns OFF, then turn ignition switch OFF within 2 seconds after the lamp turns OFF.
NOTE:
When in Diagnosis Mode, the air bag warning lamp may illuminate for more than 7 seconds after the igni-
tion switch is turned ON. If this is the case, the i gnition switch must still be cycled OFF after 7 seconds.
3. After turning ignition switch OFF, wait for 3 seconds or more.
4. Repeat operation 1 to 3 for 2 times so that operation 1 to 3 is repeated for 3 times in total.
5. Turn ignition switch from OFF to ON. Diagnosis mode changes.
USER MODE
In USER MODE, air bag warning lamp on combination meter turns ON when a malfunction is detected and
warns the customer (driver).
How to Read Air Bag Warning Lamp
1. Turn the ignition switch from OFF to ON, and check that the air bag warning lamp turns ON.
2. Compare the air bag warning lamp operation pattern with the examples.

Trouble Diagnosis with CONSULT
INFOID:0000000012430606
1. Connect CONSULT.
2. DTC is displayed on SELF-DIAG RESULTS.
NOTE:
If a malfunction is not detected on “SELF-DIAG RESULTS [CURRENT]”, but a malfunction is detected during
SRS Operation Check, the following cases may exist:
• “SELF-DIAG [PAST]” memory might not be erased. Refer to SRC-14, "
On Board Diagnosis Function".
• SRS system malfunctions intermittently. Refer to SRC-41, "
InspectionProcedure".
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 [CURRE NT]”, repair of SRS is completed. Go to step
4.
If any DTCs are detected on “SELF-DIAG RESULT S [CURRENT]”, the malfunction has not been repaired
completely or another malfunction is being detected. Perform SRS Operation Check again. Refer to SRC-
14, "On Board Diagnosis Function".
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 sh ow the previous system malfunction even if the
malfunction has been repaired completely.
5. Check that no malfunction is det ected in “SELF-DIAG [PAST]”.
6. Exit Diagnosis Mode and disconnect the CONSULT.
7. Perform SRS Operation Check. Refer to SRC-14, "
On Board Diagnosis Function".
SRS HISTORY CHECK
1. Check repair history of the SRS. If no repairs have been made, perform SRC-14, "On Board Diagnosis
Function". If repairs have been made, GO TO step 2.
2. Erase ”SELF-DIAG [PAST]” after repair. Refer to SRC-14, "
On Board Diagnosis Function".
CONSULT Function (AIR BAG)INFOID:0000000012430607
CONSULT can display each diagnostic item using the diagnostic test modes shown following.
Diagnostic Test ModeDiagnostic 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.

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.

2. All codes are proceded by a seven second "holding" flash.
3. Identify how many primary flashes are display ed as well as the length of each primary flash.
4. Refer to the tables and examples below to determine which SRS subsystem the code belongs to.
5. Count the short secondary flashes that follow the primary flashes.
6. Match the correct flashing pattern to the malfunctioning component and perform the Diagnosis Procedure.
