(a) Preconditions
The monitor will not run unless:
MIL is OFF
(b) Drive Pattern
(1) Connect the OBD II scan tool to the DLC3 to check monitor status and preconditions (refer to
step ºaº).
(2) Start the engine and allow it to idle for 500 seconds or more.
(3) Drive the vehicle at 25 mph (40 km/h) or more at least 2 minutes.
(4) Check the status of the readiness monitor on the scan tool display. If readiness status did not
switch to complete, ensure the preconditions are met, turn the ignition off and then repeat steps
(2) and (3).

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
B2610During tilt function operation, tilt operation stops within the
operation range.

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.
DTC No.DTC Detecting ConditionTrouble Area

stops within the operation range.
