1. CHECK DLC3
The terminal arrangement of the DLC3 complies with SAE J1962 and meets 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.
HINT: DTC B1795 is output if the occupant classification ECU receives the ignition switch LOCK-ON-LOCK signal 50 times in a row when a malfunction occurs in the power circuit for the occupant classification system.
