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.

4 (Chassis ground) ± Body groundAlwaysBelow 1
5 (Signal ground) ± Body groundAlwaysBelow 1
16 (B+) ± Body groundAlways10 to 14 V
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.

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.

(c) Check if the hold±in coil has an open circuit.
(1) Using an ohmmeter, check that there is continuity
between terminal 50 and the switch body.
If there is no continuity, replace the repair service kit.
8. INSPECT STARTER ARMATURE ASSY
(a) Check the commutator for open circuit.
(1) Using an ohmmeter, check that there is continuity
between the segments of the commutator.
If there is no continuity between any segments, replace the ar-
mature.
(b) Check the commutator for ground.
(1) Using an ohmmeter, check that there is no continu-
ity between the commutator and the armature coil
core.
If there is continuity, replace the armature.
(c) Check the commutator for dirty or burned surface.
If the surface is dirty or burnt, smooth the surface with 400±grit
sandpaper.
(d) Check for the commutator circuit runout.
(1) Place the commutator on V±blocks.
(2) Using a dial indicator, measure the circle runout.
Standard runout: 0.02 mm (0.0008 in.)
Maximum runout: 0.05 mm (0.0020 in.)
If the runout is greater than maximum, replace the armature.
(e) Using vernier calipers, measure the commutator diame-
ter.
Standard length: 29 mm (1.142 in.)
Minimum length: 28 mm (1.102 in.)
If the diameter is less than minimum, replace the armature.

1. DIAGNOSIS SYSTEM
(a) Description
The ECM stores trouble codes when trouble occurs on
the vehicle.
The diagnosis system allows for reading of the trouble
codes from the DLC3. If the CRUISE main indicator light
does not come on after DTC check, it means a malfunc-
tion has occurred in the cruise control system.
Use the intelligent tester II to check and solve the prob-
lem.
(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 the DLC3 complies with ISO 15031–3
and matches the ISO 9141–2/ISO 14230 format.

HINT:
If the display shows ”UNABLE TO CONNECT TO VEHICLE” af-
ter connecting the intelligent tester II to the DLC3 and turning
the ignition to the ON position, there is a problem with either the
vehicle or the tool. (Intelligent tester ll only)
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, it suggests the problem is the
tool’s own. In this case, consult Service Department listed
in the tool’s instruction manual.
