REMOVAL

CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during spiral cable sub-assembly removal/installation are shown below.

Necessary Procedures After Parts Removed/Installed/Replaced (for HV Model)

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Disconnect cable from negative auxiliary battery terminal	Perform steering sensor zero point calibration	Lane Control System
Disconnect cable from negative auxiliary battery terminal	Perform steering sensor zero point calibration	Pre-collision System

Necessary Procedures After Parts Removed/Installed/Replaced (for Gasoline Model)

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed
*1: for Hatchback
Disconnect cable from negative auxiliary battery terminal	Perform steering sensor zero point calibration	Lane Control System
		Pre-collision System
		Lighting System (w/ AFS)(EXT)
	Initialize back door lock*1	Power Door Lock Control System

NOTICE:

for HV Model:

After the power switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal. (for Audio and Visual System (for HV Model))

for Gasoline Model:

After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System (for Gasoline Model))
After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System)

5. REMOVE SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

NOTICE:

Do not remove/install the spiral cable with sensor sub-assembly with the auxiliary battery connected and the ignition switch (for Gasoline Model) or power switch (for HV Model) on (IG).
Do not rotate the spiral cable with sensor sub-assembly without the steering wheel assembly installed, with the auxiliary battery connected and the ignition switch (for Gasoline Model) or power switch (for HV Model) on (IG).
Ensure that the steering wheel assembly is installed and aligned straight when inspecting the steering sensor.

(a) Check that the ignition switch (for Gasoline Model) or power switch (for HV Model) is off.

(b) Check that the cable is disconnected from the negative (-) auxiliary battery terminal.

CAUTION:

Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

(d) Slide the slider to release the lock, and then disconnect the yellow airbag connector from the spiral cable with sensor sub-assembly.

*a	Slider
	Release in this Direction

NOTICE:

When disconnecting any airbag connector, take care not to damage the airbag wire harness.

(e) Disconnect the other connectors from the spiral cable with sensor sub-assembly.

(f) Separate the wire harness from the spiral cable with sensor sub-assembly as shown in the illustration.

Separate in this Direction

(g) Disengage the claw and 2 clips to remove the spiral cable with sensor sub-assembly.

6. REMOVE SPIRAL CABLE SUB-ASSEMBLY

NOTICE:

Remove the steering sensor from the spiral cable sub-assembly only when replacing the spiral cable sub-assembly or the steering sensor.
Removing the steering sensor from the spiral cable sub-assembly without using a lock pin may result in the center position of the steering sensor becoming misaligned. Therefore, make sure to use the lock pin provided with a new spiral cable sub-assembly when removing the steering sensor from the spiral cable sub-assembly.
When replacing the steering sensor:

(a) Install the lock pin to the steering sensor.

NOTICE:

Use the lock pin provided with a new spiral cable sub-assembly.
Do not remove the lock pin before installing the steering sensor to the spiral cable sub-assembly.

(b) Disengage the 6 claws and 2 pins to remove the spiral cable sub-assembly from the steering sensor.

NOTICE:

Do not damage the pins of the spiral cable sub-assembly or guides of the steering sensor.
