PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Description
ECM controls the function of immobiliser on this vehicle.
Data of the immobiliser or DTC can be read form DLC3 of
the vehicle. When a trouble occurs in immobiliser, MIL
does not light ON but DTC inspection is performed.
Therefore when there seems to be a trouble with immobi-
liser, use TOYOTA hand±held tester or SST to check and
troubleshoot it.
(b) DLC3 INSPECTION
The vehicle's ECM uses ISO 9141±2 for communication.
The terminal arrangement of DLC3 complies with
SAEJ1962 and matches the ISO 9141±2 format.

HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of OBD ll scan tool or TOY-
OTA hand±held tester to DLC3, turned the ignition switch ON
and operated the scan tool, there is a problem on the vehicle
side or tool side.
(1) If communication is normal when the tool is con-
nected to another vehicle, inspect DLC3 on the orig-
inal vehicle.
(2) If communication is still impossible when the tool is
connected to another vehicle, the problem is prob-
ably in the tool itself, so consult the Service Depart-
ment listed in the tool's instruction manual.

2. INSPECT DIAGNOSIS
(a) Check the DTC (Using TOYOTA hand±held tester)
(1) Prepare the OBD ll scan tool (complying with SAEJ
1978) or TOYOTA hand±held tester.
(2) Connect the OBD ll scan tool or TOYOTA hand±
held tester to DLC3 under the instrument panel low-
er pad.
(3) Turn the ignition switch ON and turn the OBD ll scan
tool or TOYOTA hand±held tester switch ON.
(4) Use the OBD ll scan tool or TOYOTA hand±held
tester to check the DTCs and freeze frame data;
note them down. (For operating instructions, see
the OBD ll scan tool's instruction book.)
(5) See page DI±924 to confirm the details of the DTCs.
(b) Check the DTC (Using diagnosis check wire)
(1) Turn ignition switch ON.
(2) Using SST, connect between terminals 8 (TE1) and
3 (E1) of DLC1.
SST 09843±18040
(3) Read the diagnostic trouble code from malfunction
indicator lamp.
HINT:

If a diagnostic trouble code is not output, check the Tc ter-
minal circuit .

ECM controls the immobiliser function on this vehicle,
DTC is out put with DTC of engine.
As an example, the blinking patterns for codes; normal, 12 and
99 are as shown in the illustration.

INSPECTION
1. INSPECT EGR SYSTEM (See page DI±358)
2. INSPECT EGR VALVE POSITION SENSOR
(a) Inspect the resistance of the EGR valve position sensor.
(1) Disconnect the EGR valve position sensor connec-
tor.
(2) Using an ohmmeter, measure the resistance be-
tween the terminals VC and E2.
Resistance: 1.5 ± 4.3 kW
If the resistance is not as specified, replace the EGR valve posi-
tion sensor.
(3) Reconnect the EGR valve position sensor connec-
tor.
(b) Inspect the power output voltage of the EGR valve posi-
tion sensor.
(1) Disconnect the vacuum hose from the EGR valve.
(2) Turn the ignition switch ON.
(3) Connect a voltmeter to terminals VC and E2 of the
ECM, and measure the power source voltage.
Voltage: 4.5 ± 5.5 V

HINT:
This check is used only to determine whether or not the idle CO/
HC complies with regulations.
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All accessories switched OFF
(e) All vacuum lines properly connected
HINT:
All vacuum hoses for EGR system, etc. should be properly con-
nected.

HINT:
When performing the 2 mode (2,500 rpm and idle) test, follow
the measurement order prescribed by the applicable local regu-
lations.
