Diagnosis System
MULTIPLEX COMMUNICATION SYSTEM: DIAGNOSIS SYSTEM
DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) The main body ECU controls the functions of the multiplex communication system on the vehicle. Data of the multiplex communication
system and the Diagnostic Trouble Codes (DTC) can be read through the Data Link Connector 3 (DLC3) of the vehicle.
2. CHECK DLC3
(a) The ECU uses ISO 15765-4 for communication. The terminal arrangement of the DLC3 complies with ISO 15031-3 and matches the ISO
15765-4 format.
CAUTION: *: 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.
(b) Techstream
HINT: Connect the cable of the Techstream to the CAN VIM, connect the CAN VIM to the DLC3, turn the ignition switch ON 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.
