B2611

STEERING COLUMN: POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM: B2611: Telescopic Position Sensor or Telescopic Motor Circuit Malfunction

DTC 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 makes the steering column slide 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 CPU based on that sliding amount.





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





WIRING DIAGRAM





INSPECTION PROCEDURE
HINT: The wire harness between the multiplex tilt and telescopic ECU and telescopic motor is provided with the steering column assembly.

PROCEDURE

1. PERFORM ACTIVE TEST USING INTELLIGENT TESTER





(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the intelligent tester on.
(c) Select "TILT & TELESCO".
(d) Select "TELESCO", and perform the test using the intelligent tester.
(e) Check that the steering column contracts (extends) when the Active Test is carried out.
OK:
Steering column contracts (extends).
OK -- INSPECT MULTIPLEX TILT & TELESCOPIC ECU (VCE TERMINAL VOLTAGE)
NG -- Continue to next step.
2. INSPECT TELESCOPIC MOTOR





(a) Disconnect connector A from the multiplex tilt and telescopic ECU.
(b) Connect the positive battery terminal to terminal TEM+ and the negative battery terminal to terminal TEM- of the telescopic motor connector. Then confirm that the steering column contracts.
OK:
Steering column contracts.
(c) Connect the negative battery terminal to terminal TEM+ and the positive battery terminal to terminal TEM- of the telescopic motor connector. Then confirm that the steering column extends.
OK:
Steering column extends.
NG -- REPLACE STEERING COLUMN ASSEMBLY
OK -- REPLACE MULTIPLEX TILT & TELESCOPIC ECU
3. INSPECT MULTIPLEX TILT & TELESCOPIC ECU (VCE TERMINAL VOLTAGE)





(a) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - TELESCOPIC POSITION SENSOR)
OK -- Continue to next step.
4. INSPECT TELESCOPIC POSITION SENSOR





(a) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- REPLACE STEERING COLUMN ASSEMBLY
OK -- REPLACE MULTIPLEX TILT & TELESCOPIC ECU
5. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - TELESCOPIC POSITION SENSOR)





(a) Disconnect connector A from the multiplex tilt and telescopic ECU.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPLACE STEERING COLUMN ASSEMBLY
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - BODY GROUND)





(a) Disconnect the T4 connector from the multiplex tilt and telescopic ECU.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE MULTIPLEX TILT & TELESCOPIC ECU
