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 makes the steering column tilt 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 angle.





HINT
Limit positions can be confirmed on the Techstream.

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM

(a) Turn the engine switch off.

(b) Connect the Techstream to the DLC3.





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

(d) Turn the Techstream on.

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

Tilt&Telescopic





OK:

The steering wheel tilts up and down.

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

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

(a) Disconnect the J28 connector from the multiplex tilt and telescopic ECU.

(b) Disconnect the J22 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. 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.

4. INSPECT MULTIPLEX TILT AND TELESCOPIC ECU (TIS TERMINAL VOLTAGE)

(a) Reconnect the J28 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.

5. INSPECT TILT POSITION SENSOR

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





Standard Voltage:

NG -- REPLACE STEERING COLUMN ASSEMBLY Removal

OK -- REPLACE MULTIPLEX TILT AND TELESCOPIC ECU Removal

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

(a) Disconnect the J28 connector from the multiplex tilt and telescopic ECU.

(b) Disconnect the J22 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.

7. INSPECT TILT MOTOR

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





OK:

The steering wheel tilts up.

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

OK:

The steering wheel tilts down.
