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 makes the steering column tilt up and down. The tilt position sensor (Hall IC) in the tilt motor detects the tilt angle of the steering column and outputs a signal to the multiplex tilt and telescopic ECU based on that angle.

A01NF8BE05

Tech Tips

Limit positions can be confirmed on the intelligent tester.

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

  • Harness or connector

  • Tilt position sensor or tilt motor

  • Multiplex tilt and telescopic ECU
