STEERING COLUMN: POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM: B2610: Tilt Position Sensor or Tilt Motor Circuit Malfunction
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 & telescopic ECU and makes the steering column tilt up and down. The tilt position sensor (hole IC) in the tilt motor detects the tilt angle of the steering column and outputs a signal to the CPU based on that tilt.





HINT
Limit positions can be confirmed on the screen of the Techstream.

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST BY TECHSTREAM

(a) Connect the Techstream to the DLC3.





(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Check that the steering wheel tilts up (down). Enter the following menus: Chassis / Tilt&Telescopic / Active Test.

Tilt&Telescopic





OK:

Steering wheel moves up (down).

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

2. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - TILT MOTOR)

(a) Disconnect the K27 connector from the multiplex tilt & telescopic ECU.





(b) Disconnect the K18 connector from the tilt motor.

(c) Measure the resistance according to the value(s) in the table below.

Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. INSPECT TILT MOTOR

(a) Connect the positive battery terminal to terminal TIM+ and the negative battery terminal to terminal TIM- of the tilt motor connector. Then confirm that the steering wheel tilts up.





OK:

Steering wheel moves up.

(b) Connect the negative battery terminal to terminal TIM+ and the positive battery terminal to terminal TIM- of the tilt motor connector. Then confirm that the steering wheel tilts down.

OK:

Steering wheel moves down.

NOTICE:
If replacing the steering column assembly, perform VGRS actuator angle initialization and VGRS actuator angle neutral calibration after wheel alignment adjustment Initialization for INITIALIZATION, Calibration for CALIBRATION).

NG -- REPLACE STEERING COLUMN ASSEMBLY

OK -- REPLACE MULTIPLEX TILT & TELESCOPIC ECU

4. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - TILT POSITION SENSOR)

(a) Disconnect the K27 connector from the multiplex tilt & telescopic ECU.





(b) Disconnect the K18 connector from the tilt motor.

(c) Measure the resistance according to the value(s) in the table below.

Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (MULTIPLEX TILT & TELESCOPIC ECU - BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.





Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

6. INSPECT MULTIPLEX TILT & TELESCOPIC ECU (VCI, TIS TERMINAL VOLTAGE)

(a) Reconnect the K27 connector to the multiplex tilt & telescopic ECU.





(b) Measure the voltage according to the value(s) in the table below.

Voltage:





NG -- REPLACE MULTIPLEX TILT & TELESCOPIC ECU
OK -- Continue to next step.

7. INSPECT TILT POSITION SENSOR

(a) Reconnect the K18 connector to the tilt motor.





(b) Measure the voltage according to the value(s) in the table below.

Voltage:

If replacing the steering column assembly, perform VGRS actuator angle initialization and VGRS actuator angle neutral calibration after wheel alignment adjustment Initialization for INITIALIZATION, Calibration for CALIBRATION).

NG -- REPLACE STEERING COLUMN ASSEMBLY

OK -- REPLACE MULTIPLEX TILT & TELESCOPIC ECU
