OPERATION CHECK
PRECAUTION FOR OPERATION CHECK
CAUTION:
Use the correct procedure to replace the airbag parts.
CHECK SRS WARNING LIGHT
(a) Primary check
(1) Turn the ignition switch to ON and check that the SRS warning light turns on.
(2) Turn the ignition switch off. Wait for at least 2 seconds, and then turn the ignition switch to ON. The SRS warning light comes on for approximately 6 seconds and diagnosis of the airbag system (including the seat belt pretensioners) is performed.
NOTICE:
Turn the ignition switch off when the auxiliary battery is connected.
HINT:
- If the warning light remains on for approximately 6 seconds or more after the ignition switch has been turned to ON, there may be a malfunction with the SRS airbag system.
- If the warning light occasionally turns on approximately 6 seconds or more after the ignition switch has been turned to ON, there may be a short to +B, short to ground or an open in the SRS warning light circuit.
- If the warning light illuminates after turning the ignition switch off or ACC, there may be a malfunction in the power source circuit or combination meter assembly.
- The SRS warning light turns off, and then turns on. This blinking pattern indicates a source voltage drop. The SRS warning light turns off 10 seconds after the source voltage returns to normal.
FUNCTION OF PASSENGER AIRBAG ON/OFF INDICATOR
(a) Initial check
(1) Turn the ignition switch to ON.
(2) The passenger airbag ON/OFF indicator comes on for approximately 4 seconds, and then goes off for approximately 2 seconds.
(3) Approximately 6 seconds after the ignition switch is turned to ON, the passenger airbag ON/OFF indicator will indicate ON/OFF depending on the following conditions.

- *1: The system judges a person of average adult weight or more as an adult. If a smaller adult sits in the front passenger seat, the system may not recognize them as an adult depending on their physique and posture.
- *2: The system may not recognize a child or a child in a child restraint system as a child depending on factors such as the positioning of the child restraint system or the child's physique or posture.
HINT:
- The timing chart below shows the operation of the passenger airbag ON/OFF indicator. Use the chart to check the indicator light circuit.
- When the occupant classification system has trouble, both the SRS warning light and passenger airbag ON/OFF indicator ("OFF") come on. In this case, check for DTCs for "Airbag System" first. Then troubleshoot the occupant classification system if DTC B1650 is output, and troubleshoot the passenger airbag ON/OFF indicator if DTC B1660 is output.
CHECK PASSENGER AIRBAG ON/OFF INDICATOR
(a) Turn the ignition switch to ON.
(b) Check that the passenger airbag ON/OFF indicator ("ON" and "OFF") comes on for approximately 4 seconds, and then goes off for approximately 2 seconds.
HINT:
In order to check the operation of the passenger airbag ON/OFF indicator when approximately 6 seconds have elapsed after turning the ignition switch to ON, refer to the table in the previous step.
