DIAGNOSIS SYSTEM
1. DESCRIPTION
Power door lock control system data can be read in the
Data Link Connector 3 (DLC3) of the vehicle. When the
system seems to be malfunctioning, use the intelligent
tester to check for malfunctions and perform repairs.
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.
NOTICE:
*: Before measuring the resistance, leave the
vehicle for at least 1 minute and do not operate
the ignition switch, any switches or 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 intelligent tester 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.
• If communication is normal when the tester is
connected to another vehicle, inspect the DLC3
of the original vehicle.
• If communication is still not possible when the
tester is connected to another vehicle, the
problem may be in the tester itself. Consult the
Service Department listed in the tester's
instruction manual.

DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST on the tester's screen.
