B2610 Tilt operation stops within the operation range while operating.
Diagnostic trouble codes
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 (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 intelligent tester.
| DTC No. |

WIRING DIAGRAM
INSPECTION PROCEDURE
| 1. PERFORM ACTIVE TEST BY INTELLIGENT TESTER |
Connect the intelligent tester to the DLC3.
Turn the ignition switch to the ON position and turn the intelligent tester on.
Select "Tilt & Telescopic".
Touch the "Active Test" button.
Select "Tilt Operation", and perform the test using the intelligent tester.
Check that the steering wheel tilts up (down) when the Active Test is carried out.
- OK:
- Steering wheel tilts up (down).

| 2. CHECK HARNESS AND CONNECTOR (BETWEEN TILT & TELESCOPIC ECU AND TILT MOTOR) |
Disconnect the T4 connector from the multiplex tilt & telescopic ECU.
Disconnect the T5 connector from the tilt motor.
Measure the resistance according to the value(s) in the table below.
- Resistance:
Tester connection
(Terminal No.)
Condition
Specified value
TIM+ (T4-10) - TIM+ (T5-1)
Always
Below 1 Ω
TIM- (T4-1) - TIM- (T5-2)
Always
Below 1 Ω
TIM+ (T4-10) - Body ground
Always
10 kΩ or higher
TIM- (T4-1) - Body ground
Always
10 kΩ or higher
|
|
||||
| OK | |
|
| 3. INSPECT TILT MOTOR |
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 tilts up.
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 tilts down.

| 4. CHECK HARNESS AND CONNECTOR (BETWEEN TILT & TELESCOPIC ECU AND TILT POSITION SENSOR) |
Disconnect the T4 connector from the multiplex tilt & telescopic ECU.
Disconnect the T5 connector from the tilt motor.
Measure the resistance according to the value(s) in the table below.
- Resistance:
Tester connection
(Terminal No.)
Condition
Specified value
VCI (T4-6) - VCI (T5-4)
Always
Below 1 Ω
TIS (T4-7) - TIS (T5-5)
Always
Below 1 Ω
E1 (T4-17) - E1 (T5-6)
Always
Below 1 Ω
VCI (T4-6) - Body ground
Always
10 kΩ or higher
TIS (T4-7) - Body ground
Always
10 kΩ or higher
E1 (T4-17) - Body ground
Always
10 kΩ or higher
|

| OK | |
|
| 5. CHECK HARNESS AND CONNECTOR (BETWEEN TILT & TELESCOPIC ECU AND BODY GROUND) |
Measure the resistance according to the value(s) in the table below.
- Resistance:
Tester connection
(Terminal No.)
Condition
Specified value
GND (T4-11) - Body ground
Always
Below 1 Ω
|
|
||||
| OK | |
|
| 6. INSPECT MULTIPLEX TILT & TELESCOPIC ECU (VCI, TIS TERMINAL VOLTAGE) |
Reconnect the T4 connector to the multiplex tilt & telescopic ECU.
Measure the voltage according to the value(s) in the table below.
- Voltage:
Tester connection
(Terminal No.)
Condition
Specified value
VCI (T5-4) - E1 (T5-6)
Ignition switch on
8 to 16 V
TIS (T5-5) - E1 (T5-6)
Ignition switch on
8 to 16 V
|
|
||||
| OK | |
|
| 7. INSPECT TILT POSITION SENSOR |
Reconnect the T5 connector to the tilt motor.
Measure the voltage according to the value(s) in the table below.
- Voltage:
Tester connection
(Terminal No.)
Condition
Specified value
TIS (T4-7) - E1 (T4-17)
Steering tilts up or tilts down
8 to 16 V (Pulse HI)
