(7) Select the component (Label) and press ENTER.
The accuracy test value appears when the monitor
result is either PASS or FAIL.
VAL The test value
LMT: The test limit
TLT: The test limit type. Either 0 or 1 is displayed.
(8) If TLT is 0, the component is malfunctioning when
the test value is higher than the test limit. If TLT is
1, the component is malfunctioning when the test
value is lower than the test limit.
(9) Compare the test value with the test limit. The test
value is usually significantly higher or lower than the
test limit. If the test value is on the borderline of the
test limit, there is a potential malfunction in the com-
ponent.
HINT:
The monitor result might on rare occasions be PASS even if the
MIL is illuminated. This indicates the system malfunctioned on
a previous driving cycle. This might be caused by an intermit-
tent problem.

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 from DLC3 of
the vehicle. When a trouble occurs on immobiliser, MIL
does not light up but DTC inspection is performed.
Therefore when there seems to be a trouble on immobilis-
er, use hand-held tester or SST to check and trouble-
shoot it.
(b) Inspect the DLC3.
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.

4 (Chassis Ground) - BodyAlways1 W or less
5 (Signal Ground) - BodyAlways1 W or less
16 (B+) - BodyAlways9 - 14 V
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of hand-held tester to
DLC3, turned the ignition switch ON and operated the hand-
held tester, there is a problem on the vehicle side or tool side.

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

If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.

(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

1. DESCRIPTION
(a) DIAGNOSIS SYSTEM
When troubleshooting Multiplex OBD (M-OBD) vehicles,
the only difference from the usual troubleshooting proce-
dure is that you connect the TOYOTA hand-held tester
to vehicle, and read off various data output from the ve-
hicle's Power Tilt and Telescopic Steering ECU.
The Power Tilt and Telescopic Steering ECU records the
applicable DTCs when the computer detects a malfunc-
tion in the computer itself or its circuit.
To check the DTCs, connect a TOYOTA hand-held tester
to DLC3 on the vehicle. The TOYOTA hand-held tester
enables you to erase the DTCs and activate the several
actuators and check freeze frame data and various forms
on steering data.
(b) DATA LINK CONNECTOR 3 (DLC3)
The Power Tilt and Telescopic Steering ECU uses ISO
14230 for communication. The terminal arrangement of
DLC3 complies with SAE J1962 and matches the ISO
14230 format.

HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of TOYOTA hand-held
tester to DLC3, turned the ignition switch ON and operated the
TOYOTA 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 DLC3 on the original vehicle.

If communication is still not possible 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 Operator's Manual.
