(b) Turn ignition switch ON and push the TOYOTA hand-held
tester main switch ON.
(c) Select the ACTIVE TEST mode on the TOYOTA hand-
held tester.
CHECK:
Check that the steering wheel tilt up (down) and confirm that tilt
position value change when the ACTIVE TEST carried out.
OK:
Steering wheel must be moved upward (downward).
Tilt position value must be changed.
OK Proceed to next circuit inspection shown on the
problem symptoms table (See page DI-663).
NG
2 Check tilt motor.

Tilt and Telescopic Manual Switch Circuit
CIRCUIT DESCRIPTION
The different voltage signals which are occurred by operating the manual switch are sent to the tilt and tele-
scopic ECU.

PRE-CHECK
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.
Terminal No.ConnectionVoltage or ResistanceCondition
7Bus + LinePulse generationDuring transmission
4Chassis Grounde Body Ground 1 W or lessAlways
5Signal Grounde Body Ground 1 W or lessAlways
16Battery Positivee Body Ground 9 - 14 VAlways
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.

2. DIAGNOSIS INSPECTION
(a) Check the DTC.
(1) Prepare the TOYOTA hand-held tester.
(2) Connect the TOYOTA hand-held tester to DLC3 at
the lower of the instrument panel.
(3) Turn the ignition switch ON and turn the TOYOTA
hand-held tester switch ON.
(4) Use the TOYOTA hand-held tester to check the
DTCs and freeze frame data, note or print them
(See the Operator's Manual for operating instruc-
tions.).
(5) See page DI-660 to confirm the details of the DTC.
(b) Clear the DTC.
The following actions will erase the DTC and freeze frame
data.
When using the TOYOTA hand-held tester:
Operating the TOYOTA hand-held tester to erase
the DTCs (See the Operator's Manual for operating
instructions.).
When not using the TOYOTA hand-held tester:
Disconnecting the battery terminals.
