DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) Engine immobiliser system data and Diagnostic
Trouble Codes (DTCs) can be read through the
vehicle's Data Link Connector 3 (DLC3). In some
cases, a malfunction may be occurring in the engine
immobiliser system even though the security
indicator light is not illuminated. When the system
seems to be malfunctioning, use the intelligent
tester to check for malfunctions and perform repairs.
2. CHECK DLC3
The vehicle's ECU uses the ISO 15765-4 communication
protocol. The terminal arrangement of the DLC3
complies with SAE J1962 and matches 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, other 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 (with CAN
VIM) to the DLC3, turn the ignition switch ON and
attempt to use the intelligent tester. If the screen displays
UNABLE TO CONNECT TO VEHICLE, a problem exists
in the vehicle side or the tester side.
If the communication is normal when the tester is
connected to another vehicle, inspect the DLC3 on the
original vehicle.
If the communication is still not possible 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.
DTC CHECK / CLEAR
1. CHECK DTC
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON and turn the intelligent
tester ON.
(c) Select the following menu items: DIAGNOSIS /
OBD/MOBD / IMMOBILISER / DTC INFO /
CURRENT CODES.
(d) Check DTCs and then write them down.
HINT:
Refer to the intelligent tester operator's manual for
further details.
(e) Confirm the details of the DTCs (see page EI-20).
2. CLEAR DTC
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON (do not start the engine)
and turn the intelligent tester ON.
(c) Select the following menu items: DIAGNOSIS /
OBD/MOBD / IMMOBILISER / DTC INFO / CLEAR
CODES.
HINT:
Refer to the intelligent tester operator's manual for
further details.
(d) Erase DTCs by pressing the YES button on the
tester.
