PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Inspect the DLC3.
HINT:
The vehicle's ECM uses the ISO 14230 (M±OBD) communica-
tion protocol. The terminal arrangement of DLC3 complies with
ISO 15031±03 and matches the ISO 14230 format.

4 (Chassis ground) ± Body groundConstantBelow 1

5 (Signal ground) ± Body groundConstantBelow 1

16 (B+) ± Body groundConstant9 to 14 V
HINT:
If the display shows UNABLE TO CONNECT TO VEHICLE when you have connected the cable of the hand±
held tester to the DLC3, turned the ignition switch ON and used the hand±held tester, there is a problem on
the vehicle side or tester side.

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, so consult the Service Department listed in the tester's manual.
(b) Check the battery voltage.
Battery voltage: 11 to 14 V
If voltage is below 11V, recharge the battery before proceeding.
2. USING HAND±HELD TESTER
(a) Connect the hand±held tester to the DLC3.
(b) Monitor the ECU data by following the prompts on the tes-
ter screen.
HINT:
The hand±held tester has a ºSnapshotº function which records
the monitored data.
Refer to the hand±held tester operator's manual for further de-
tails.

± DIAGNOSTICSENGINE IMMOBILISER SYSTEM
AVENSIS REPAIR MANUAL (RM1018E)
PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Description
(1) The ECM controls the function of the immobiliser system on the vehicle.
Data of the immobiliser system and the Diagnostic Trouble Code (DTC) can be read in the Data
Link Connector 3 (DLC3) of the vehicle. When trouble occurs in the immobiliser system, even
though the security indicator lamp does not come on, DTCs can be checked.
Therefore, the immobiliser system seems to be malfunctioning, use the hand±held tester to
check for a malfunction and repair it.
(b) Inspect the DLC3.
The vehicle's ECM uses the ISO 9141±2 (Euro±
OBD)/ISO 14230 (M±OBD) communication protocol.
The terminal arrangement of the DLC3 complies with the
ISO 15031±3 and matches the ISO 9141±2/ISO 14230
format.

HINT:
If the screen displays UNABLE TO CONNECT TO VEHICLE after you have connected the cable of the
hand±held tester to the DLC3, turned the ignition switch ON and used the hand±held tester, the problem
may be on the vehicle side or the tester side.

If communication is normal when the tester is connected to other vehicle, inspect the DLC3 of the origi-
nal vehicle.

If communication is still impossible when the tester is connected to another vehicle, the problem may
be in the tester itself, so consult the Service Department listed in the tester's instruction manual.
2. Using hand±held tester:
CHECK DTC
(a) Checking DTCs.
(1) Connect the hand±held tester to DLC3.
(2) Turn the ignition switch ON.
(3) Read DTCs by following the prompts on the tester screen.
HINT:
Refer to the hand±held tester operator's manual for further details.
(b) Clear the DTCs from memory.
(1) Connect the hand±held tester to DLC3.
(2) Turn the ignition switch ON.
(3) Erase DTCs by following the prompts on the tester screen.
HINT:
Refer to the hand±held tester operator's manual for further details.

± DIAGNOSTICSCRUISE CONTROL SYSTEM
AVENSIS REPAIR MANUAL (RM1018E)
PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Description
ECM controls of the cruise control the function on a ve-
hicle.
Data stored in the cruise control memory and on the DTC
can be read from the DLC3 on the vehicle. If CRUISE
MAIN indicator light does not come on after the DTC
check, there is a malfunction of the cruise control.
Use the hand±held tester or SST to check and solve the
problem.
(b) Check the DLC3.
The vehicle's ECM uses ISO 9141±2(Euro±OBD)/ISO
14230 (M±OBD) for communication protocol. The termi-
nal arrangement of DLC3 complies with ISO 15031±3
and matches the ISO 9141±2 / ISO 14230 format.

HINT:
If the display shows ºUNABLE TO CONNECT TO VEHICLEº af-
ter connecting the hand±held tester to the DLC3 and turning the
ignition ON, there is a problem either with the vehicle or with the
tool.

If communication is normal when connecting the tool to
another vehicle, inspect the DLC3 on the original vehicle.

If communication is still not possible when connecting the
tool to another vehicle, the problem is probably in the tool
itself. Consult the Service Department listed in the tool's
instruction manual.

(a) Remove the 4 screws, and then remove the rear floor ser-vice hole cover.
(b) Disconnect the fuel pump connector.
4. DISCONNECT FUEL TANK RETURN TUBE (1AZ±FSE ENGINE TYPE)
(a) Remove the tube joint clip, and pull out the fuel return tube.
NOTICE:

Check if there is any dirt or mud around the connector
before this operation and remove the dirt as neces-
sary.

Be careful of mud because the fuel tube joint has an
O±ring which seals the pipe and connector that can
be contaminated.

Do not use any tool in this operation.

Do not bend or twist the nylon tube. Protect the con-
nector by covering it with a vinyl or plastic bag.

When the pipe and connector are stuck, push and pull
the connector to release and pull the connector out
carefully.
