2. INSPECT DIAGNOSIS
(a) Check the DTC (Using hand-held tester).
(1) Prepare hand-held tester.
(2) Connect hand-held tester to DLC3 under the instru-
ment panel lower pad.
(3) Turn the ignition switch ON and turn hand-held tes-
ter switch ON.
(4) Use hand- held tester to check the DTCs. and
ºSnap-shot functionº which records the monitor
data (For operating instructions, see the hand-held
tester instruction book.).
(5) See page DI-1007 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 11 (TC) and
3 (E1) of DLC1.
SST 09843-18020
(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 engine data.
As an example, the blinking patterns for codes; normal,
12 and 99 are shown in the charts.

(4) When DTC º99º is output, there is a trouble of
immobiliser. Start troubleshooting referring to
PROBLEM SYMPTOMS TABLE.
(5) After completing the check, disconnect terminals 11
(TC) and 3 (E1) and turn off the display.
HINT:
In the event of 2 or more malfunction codes, indication will begin
from the smaller numbered code and continue in order to the
larger.
(c) Clear the DTC.
The following operations will erase the DTCs and freeze
frame data.
(1) Operating the hand-held tester to erase the codes
(See the hand-held tester instruction book for oper-
ating instructions.).
(2) Disconnecting the battery terminals or EFI fuse.
3. CHECK HAND-HELD TESTER
(a) ECU DATA MONITOR
(1) Make a judgement of good or bad and find out a malfunctioning part by the data monitor.
