DTC B2610 Tilt Position Sensor or Tilt Motor Circuit Malfunction
DESCRIPTION
The tilt motor is operated by the power source voltage supplied from the multiplex tilt and telescopic ECU and tilts the steering column up and down. The tilt position sensor (Hall IC) in the tilt motor detects the tilt angle of the steering column and outputs a signal to the CPU based on that tilt.
- Limit positions can be confirmed on the screen of the intelligent tester.
| DTC Code | Detection Condition | Trouble Area |
| B2610 | The tilt operation stops within the operation range while operating. | Harness or connector
Tilt position sensor or tilt motor
Multiplex tilt and telescopic ECU

WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (TILT UP/DOWN) |
Select the Active Test, use the intelligent tester to generate a control command, and then check that the steering wheel tilts up and down.
Tilt & Telescopic| Tester Display | Test Part | Control Range | Diagnostic Note |
| Tilt Operation | Tilt operation | Up/Down | - |
Result| Result | Proceed to |
| Steering wheel does not tilt up/down. | A |
| Steering wheel tilts up/down. | B |
| 2.CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - TILT MOTOR) |
Disconnect the E27 multiplex tilt and telescopic ECU connector.
Disconnect the E17 tilt motor connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| E27-10 (TIM+) - E17-1 (TIM+) | Always | Below 1 Ω |
| E27-1 (TIM-) - E17-2 (TIM-) |
| E27-10 (TIM+) - Body ground | Always | 10 kΩ or higher |
| E27-1 (TIM-) - Body ground |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
Apply 12 V battery voltage to the tilt motor connector. Then check the steering wheel tilt operation.
- OK:
| Measurement Condition | Specified Condition |
12 V battery positive (+) lead → Terminal E17-1 (TIM+)
12 V battery negative (-) lead → Terminal E17-2 (TIM-) |
The steering wheel tilts up. |
12 V battery positive (+) lead → Terminal E17-2 (TIM-)
12 V battery negative (-) lead → Terminal E17-1 (TIM+) |
The steering wheel tilts down. |

| 4.CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - TILT POSITION SENSOR) |
Disconnect the E27 multiplex tilt and telescopic ECU connector.
Disconnect the E17 tilt motor connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| E27-6 (VCI) - E17-4 (VCI) | Always | Below 1 Ω |
| E27-7 (TIS) - E17-5 (TIS) |
| E27-17 (E1) - E17-6 (E1) |
| E27-6 (VCI) - Body ground | Always | 10 kΩ or higher |
| E27-7 (TIS) - Body ground |
| E27-17 (E1) - Body ground |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 5.CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT AND TELESCOPIC ECU - BODY GROUND) |
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 |
|
|
| 6.CHECK MULTIPLEX TILT AND TELESCOPIC ECU (VCI, TIS TERMINAL VOLTAGE) |
Reconnect the E27 multiplex tilt and telescopic ECU connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| E17-4 (VCI) - E17-6 (E1) | Engine switch on (IG) | 8 to 16 V |
| E17-5 (TIS) - E17-6 (E1) |
| | REPLACE MULTIPLEX TILT AND TELESCOPIC ECU ()
|
|
|
| 7.CHECK TILT POSITION SENSOR |
Reconnect the E17 tilt motor connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Condition | Specified Condition |
| E27-7 (TIS) - E27-17 (E1) | Steering tilting up or tilting down | Pulse generation
High: 8 to 16 V
Low: Below 1 V |
