(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

DTC B2610 Tilt Position Sensor or Tilt Motor Circuit
Malfunction
CIRCUIT DESCRIPTION
Tilt motor is operated by the power voltage supplied from tilt and
telescopic ECU and makes the steering column tilt upward and
downward. Tilt position sensor (Hole IC) in the tilt motor detects
the tilt of the steering column and outputs the signal to the CPU
in response to that tilt.
HINT:
Limit positions can be confirmed on the screen of the TOYOTA
hand-held tester.
DTC No.DTC Detecting ConditionTrouble Area

DTC B2611 Telescopic Position Sensor or Telescopic
Motor Circuit Malfunction
CIRCUIT DESCRIPTION
Telescopic motor is operated by the power voltage supplied
from tilt and telescopic ECU and makes the steering column
slide forward and rearward. Telescopic position sensor (Hole
IC) in the telescopic motor detects the sliding position of the for-
ward and rearward direction of the steering column and outputs
the signal to the CPU in response to that sliding amount.
HINT:
Limit positions can be confirmed on the screen of the TOYOTA
hand-held tester.

The indicator output the condition of the alarm control and the
intrusion sensor control as shown below.
ConditionIndicator light
Disarmed stateOFF
Arming preparationON
Armed state
(Entry delay time)OFF
(ON)
Alarm soundingON
HINT:
Even in disarmed state, the indicator light flashes. (Due to the
signal output from immobiliser system). The indicator always
flashes by receiving the signal from the immobiliser system at
any time in the arming condition.
Flashing frequency:
0.2 seconds (ON)
1.8 seconds (OFF)
Response:
The hazard lights flash under the following conditions.
(1) When the system is set.
When arming preparation is set from disarmed state
using the wireless door lock, the hazard lights flash
once.
(2) When the system is released.
When disarmed state is set from either arming prep-
aration, armed state or alarm sounding using the
wireless door lock, the hazard lights flash twice.
5. SWITCH TO ACTIVE MODE
In each passive mode, when ºdisarmed state of active mode "
arming preparation switch conditionº is met, the active mode
switch to each condition. In this case, active mode continues till
disarmed state.
