POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM, Diagnostic DTC:B2610

DTC Code DTC Name
B2610 Tilt Position Sensor or Tilt Motor Circuit Malfunction

DESCRIPTION

The tilt motor is operated by the power source voltage supplied from the multiplex tilt and telescopic ECU and tilts the steering column up and down. The tilt position sensor (Hall IC) in the tilt motor detects the tilt angle of the steering column and sends a signal to the multiplex tilt and telescopic ECU based on that angle.

A0004FNE17

Tech Tips

Limit positions can be confirmed on the GTS.

DTC No. Detection Condition Trouble Area
B2610 Tilt operation stops within the operation range while operating.

  • Tilt position sensor or tilt motor

  • Harness or connector

  • Multiplex tilt and telescopic ECU

CAUTION / NOTICE / HINT

Note

If the electric power steering column sub-assembly has been replaced with a new one, perform torque sensor zero point calibration after performing the initialization of the torque sensor zero point value Click here.

Tech Tips


  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

  • The wire harness between the multiplex tilt and telescopic ECU and tilt motor is provided with the electric power steering column sub-assembly.
