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.

(4) When DTC º99º is output, there is a trouble with
immobiliser. Start troubleshooting referring to
PROBLEM SYMPTOM TABLE.
(5) After completing the check, disconnect terminals 13
(TC) and 4 (CG) 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 procedures will erase the DTCs and freeze frame
data.
(1) Operating the OBD ll scam tool (complying with
SAEJ1978) or TOYOTA hand±held tester to erase
the codes. (See the OBD ll scan tool's instruction
book for operating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.

CIRCUIT INSPECTION
DTC B2795/99 Unmatched Key Code
This DTC is output when an unregistered key is inserted. When this DTC is output, delete DTC and insert
the key that a customer keeps to check that B2795 is output.
When a key that outputs B2795 is found, register this key. When B2795 is not output, there is a possibility
that the unregistered key has been inserted before. (ECM is normal.)
Inquire of a customer about the condition of using the system to find the cause of the trouble.
(Example: Another key has been inserted, etc.)
