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 the power source 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 in the forward and backward directions of the steering column and outputs a signal to the multiplex tilt and telescopic ECU based on that sliding amount.

A01GWS3E02

Tech Tips

Limit positions can be confirmed on the screen of the intelligent tester.

DTC Code Detection Item Trouble Area
B2611 Telescopic operation stops within the operation range while operating.

  • Harness or connector

  • Telescopic position sensor or telescopic motor

  • Multiplex tilt and telescopic ECU
