1. CHECK DLC3
The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format.
NOTICE: *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches, or the doors.
If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector.
HINT: If the display shows a communication error message when connecting the cable of the intelligent tester to the DLC3, turning the ignition switch to the ON position and operating the intelligent tester, there is a problem on the vehicle side or tool side.
2. 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.
HINT: Perform the simulation method only during the primary check period (for approximately 6 seconds after the ignition switch is turned to the ON position).
HINT: Shaking the relays too strongly may result in open relays.
The connector joint and fulcrum of the vibration are the major areas to be checked thoroughly.
3. FUNCTION OF SRS WARNING LIGHT
After 2 seconds or more, turn the ignition switch to the ON position. The SRS warning light comes on for approximately 6 seconds and the diagnosis of the SRS airbag system (including the seat belt pretensioner and front passenger occupant classification system) is performed.
HINT: If trouble is detected during the primary check, the SRS warning light remains on even after the primary check period (for approximately 6 seconds) has elapsed.
HINT: If trouble is detected during the constant check, the center airbag sensor assembly functions as follows:
HINT: The center airbag sensor assembly keeps the SRS warning light on if the airbag has been deployed.
4. SRS WARNING LIGHT CHECK
HINT: When any of the following symptoms occur, refer to the "Problem Symptoms Table" (3).
5. FUNCTION OF PASSENGER AIRBAG ON/OFF INDICATOR
HINT:
Then troubleshoot the Occupant Classification System if DTC B1150/23 is detected, and troubleshoot the passenger airbag ON/OFF indicator if DTC B1152/28 is detected.
6. PASSENGER AIRBAG ON/OFF INDICATOR CHECK
HINT: Refer to the table in the previous step regarding the passenger airbag ON/ OFF indicator when the ignition switch is turned to the ON position and approximately 6 seconds pass.
7. ACTIVATION PREVENTION MECHANISM
CAUTION: Never release the activation prevention mechanism on the squib connector even when inspecting with the squib disconnected.
