STEERING COLUMN: POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM: B2611: Telescopic Position Sensor or Telescopic Motor Circuit Malfunction
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 amount that the steering column slides forward or backward and outputs a signal to the multiplex tilt and telescopic ECU based on that sliding amount.
HINT
The limit positions can be confirmed on the Data List screen of the Techstream.

INSPECTION PROCEDURE
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
PROCEDURE
1. PERFORM ACTIVE TEST USING TECHSTREAM (TELESCO OPERATION)
(a) Select the Active Test, use the Techstream to generate a control command, and then check that the steering column contracts and extends.
