2. INSPECT OCCUPANT CLASSIFICATION ECU (VEHICLE INVOLVED IN COLLISION)
a. Perform a diagnostic system check
b. Even if the airbag was not deployed, check if there is any damage to the occupant classification ECU. If there are any defects as mentioned
below, replace the occupant classification ECU with a new one:
-
Cracks, dents or chips on the case.
-
Cracks or other damage to the connector.
CAUTION: Be sure to follow the correct removal and installation procedures.
Function of Passenger Airbag ON/OFF Indicator
FUNCTION OF PASSENGER AIRBAG ON/OFF INDICATOR
a. Initial check
1. Turn the ignition switch to the ON position.
2. The passenger airbag ON/OFF indicator ("ON" and "OFF") comes on for approximately 4 seconds, then goes off for approximately 2 seconds
.
3. Approximately 6 seconds after the ignition switch is turned to the ON position, the passenger airbag ON/OFF indicator will be ON/ OFF
depending on the conditions listed.
HINT:
-
The passenger airbag ON/OFF indicator is based on the timing chart in order to check the indicator light circuit.
-
When the occupant classification system has trouble, both the SRS warning light and the passenger airbag ON/OFF indicator ("OFF")
come on. In this case, check the DTCs in the "AIRBAG SYSTEM" first.
Symptom Simulation
SYMPTOM SIMULATION
HINT: The most difficult case in troubleshooting is when no symptoms occur. In such cases, a thorough customer problem analysis must be carried out.
Then the same or similar conditions and environment in which the problem occurred in the customer's vehicle should be simulated. No matter how
experienced or skilled a technician may be, if he proceeds to troubleshoot without confirming the problem symptoms, he will likely overlook something
important and make a wrong guess at some points in the repair operation. This leads to a standstill in troubleshooting.
