DIAGNOSIS SYSTEM





1. CHECK DLC3
HINT: The vehicle uses the ISO 15765-4 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format.





NOTE: *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the power 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: Connect the cable of the Techstream to the DLC3, turn the power switch ON (IG) and attempt to use the Techstream. If the display informs that a communication error has occurred, there is a problem either with the vehicle or with the tester.
- If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle.
- If communication is still impossible when the tester is connected to another vehicle, the problem is probably in the tester itself. Consult the Service Department listed in the tester's instruction manual.

2. INSPECT BATTERY VOLTAGE
Standard:
11 to 14 V
If the voltage is below 11 V, replace the battery before proceeding.
