POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM, Diagnostic DTC:B2611

DTC Code DTC Name
B2611 Telescopic Position Sensor or Telescopic Motor Circuit Malfunction

DESCRIPTION

The telescopic motor is operated by voltage supplied from the multiplex tilt and telescopic ECU and slides the steering column forward and backward. The telescopic position sensor (Hall IC) in the telescopic motor detects the sliding position of the steering column in the forward and backward directions and sends a signal to the multiplex tilt and telescopic ECU based on that sliding amount.

A01EWENE02

Tech Tips

Limit positions can be confirmed on the intelligent tester.

DTC No. Detection Item Trouble Area
B2611 Telescopic operation stops within the operation range while operating.

  • Telescopic position sensor or telescopic motor

  • Harness or connector

  • Multiplex tilt and telescopic ECU

INSPECTION PROCEDURE

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 telescopic motor is provided with the electric power steering column sub-assembly.
