1. DESCRIPTION
The clearance warning ECU records DTCs when the computer detects a malfunction in the computer itself or in its circuits.
To check the DTCs, connect the intelligent tester to the DLC3 on the vehicle. The intelligent tester enables you to erase the DTCs, activate the various actuators, and check the freeze frame data and Data List.
2. CHECK DLC3
The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format.
If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness or connector.
Standard
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.
HINT: Connect the cable of the intelligent tester to the DLC3, turn the power switch ON (IG) and attempt to use the tester. If the display indicates that a communication error has occurred, there is a problem either with the vehicle or with the tester.
