B2610

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 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.





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

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (TILT UP/DOWN)





(a) Select the Active Test, use the Techstream to generate a control command, and then check that the tilt up/down.

Tilt & Telescopic:





OK:

Steering wheel tilts up (down).

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

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

(a) Disconnect the L34 connector from the multiplex tilt and telescopic ECU.

(b) Disconnect the L26 connector from the tilt motor.

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

Standard 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 1 (TIM+) and the negative (-) battery terminal to terminal 2 (TIM-) of the tilt motor connector. Then confirm that the steering wheel tilts up.

OK:

The steering wheel tilts up.

(b) Connect the negative (-) battery terminal to terminal 1 (TIM+) and the positive (+) battery terminal to terminal 2 (TIM-) of the tilt motor connector. Then confirm that the steering wheel tilts down.

OK:

The steering wheel tilts down.

NG -- REPLACE STEERING COLUMN ASSEMBLY (TILT STEERING GEAR ASSEMBLY WITH MOTOR) Removal

OK -- REPLACE MULTIPLEX TILT AND TELESCOPIC ECU Removal

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

(a) Disconnect the L34 connector from the multiplex tilt and telescopic ECU.

(b) Disconnect the L26 connector from the tilt motor.

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

Standard resistance:





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

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

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





Standard resistance:





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

6. CHECK MULTIPLEX TILT AND TELESCOPIC ECU (VCI, TIS TERMINAL VOLTAGE)

(a) Reconnect the L34 connector to the multiplex tilt and telescopic ECU.





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

Standard voltage:





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

7. CHECK TILT POSITION SENSOR

(a) Reconnect the L26 connector to the tilt motor.





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

Standard voltage:





NG -- REPLACE STEERING COLUMN ASSEMBLY (TILT STEERING GEAR ASSEMBLY WITH MOTOR) Removal

OK -- REPLACE MULTIPLEX TILT AND TELESCOPIC ECU Removal
