1. DIAGNOSIS SYSTEM
(a) Description
ECM controls the function of cruise control on this vehicle.
Data of the cruise control or DTC can be read from DLC3
of the vehicle. When a trouble occurs on cruise control,
Check CRUISE MAIN indicator does not light up but DTC
inspection is performed.
Therefore when there seems to be a trouble on cruise
control, use hand-held tester or SST to check and trou-
bleshoot it.
(b) Check the DLC3.
The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of DLC3 complies with SAE
J1962 and matches the ISO 9141-2 format.

13TC e Body Ground/9 - 14 VAlways
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the 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.

(b) Check the DLC3.
The vehicle's ECM uses the ISO 9141-2 for communica-
tion protocol. The terminal arrangement of the DLC3 com-
plies with SAE J1962 and matches the ISO 9141-2 for-
mat.

HINT:
Connect the cable of the hand-held tester to the DLC3, turn the
ignition switch ON and attempt to use the hand-held tester. If
the screen displays UNABLE TO CONNECT TO VEHICLE, a
problem exists in the vehicle side or the tester side.
If the communication is normal when the tool is connected
to another vehicle, inspect the DLC3 on the original ve-
hicle.
If the communication is still impossible when the tool is
connected to another vehicle, the problem is probably in
the tool itself, so consult the Service Department listed in
the tool's instruction manual.
(c) Inspect the battery voltage.
Battery Voltage: 11 to 14 V
If voltage is below 11 V, recharge the battery before proceeding.
(d) Check the MIL.
(1) The MIL comes on when the ignition switch is turned
ON and the engine is not running.
HINT:
If the MIL is not illuminated, troubleshoot the MIL circuit (See
page DI-355).
(2) When the engine is started, the MIL should not illu-
minate. If the lamp remains on, the diagnosis sys-
tem has detected a malfunction or abnormality in
the system.

Data of the immobiliser or DTC can be read from DLC3 of

Therefore when there seems to be a trouble on immobilis-
er, use hand-held tester or SST to check and trouble-
shoot it.

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.
