DTC B2603 Tilt and Telescopic Manual switch circuit
Malfunction
CIRCUIT DESCRIPTION
The different voltage value is input to tilt and telescopic ECU by operating the manual switch. Then tilt and
telescopic ECU judges which motor and which direction tilt motor or telescopic motor should be moved based
on the voltage value.
DTC No.DTC Detecting ConditionTrouble Area

The abnormal voltage value which is not within the specifi-
cation is input to tilt and telescopic ECU when being oper-
ated with the manual switch.Tilt and telescopic manual switch circuit

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.
