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 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.
- Limit positions can be confirmed on the screen of the intelligent tester.
| DTC Code | Detection Condition | Trouble Area |
| B2611 | The telescopic operation stops within the operation range while operating. | Harness or connector
Telescopic position sensor or telescopic motor
Multiplex tilt and telescopic ECU

WIRING DIAGRAM
INSPECTION PROCEDURE
- The wire harness between the multiplex tilt and telescopic ECU and telescopic motor is provided with the steering column assembly.
| 1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (TELESCOPIC SHORT/LONG) |
Select the Active Test, use the intelligent tester to generate a control command, and then check that the steering column contracts and extends.

| The steering column does not contract/extend. | A |
| The steering column contracts/extends. | B |
Disconnect connector A from the multiplex tilt and telescopic ECU.
Apply 12 V battery voltage to the multiplex tilt and telescopic ECU connector. Then check the steering wheel telescopic operation.
- OK:
| Measurement Condition | Specified Condition |
12 V battery positive (+) lead → Terminal A-2 (TEM+)
12 V battery negative (-) lead → Terminal A-6 (TEM-) |
The steering column contracts. |
12 V battery positive (+) lead → Terminal A-6 (TEM-)
12 V battery negative (-) lead → Terminal A-2 (TEM+) |
The steering column extends. |
| | REPLACE STEERING COLUMN ASSEMBLY (TILT STEERING GEAR ASSEMBLY WITH MOTOR) ()
|
|
|
| OK | |
| |
| REPLACE MULTIPLEX TILT AND TELESCOPIC ECU ()
|
|
| 3.CHECK MULTIPLEX TILT AND TELESCOPIC ECU (VCE TERMINAL VOLTAGE) |
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| A-3 (VCE) - A-5 (E2) | Engine switch on (IG) | 8 to 16 V |
| 4.CHECK TELESCOPIC POSITION SENSOR |
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Condition | Specified Condition |
| A-4 (TES) - A-5 (E2) | Telescopic steering contracting or extending | Pulse generation
High: 8 to 16 V
Low: Below 1 V |
| | REPLACE STEERING COLUMN ASSEMBLY (TILT STEERING GEAR ASSEMBLY WITH MOTOR) ()
|
|
|
| OK | |
| |
| REPLACE MULTIPLEX TILT AND TELESCOPIC ECU ()
|
|
| 5.CHECK HARNESS AND CONNECTOR (ECU - TELESCOPIC POSITION SENSOR) |
Disconnect connector A from the multiplex tilt and telescopic ECU.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| A-3 (VCE) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 6.CHECK HARNESS AND CONNECTOR (ECU - BODY GROUND) |
Disconnect the E27 multiplex tilt and telescopic ECU connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| E27-11 (GND) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
| |
| REPLACE MULTIPLEX TILT AND TELESCOPIC ECU ()
