DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE

id041500870300

Warning

•  If the initialization of the sensors for DSC-related parts is not completed, the DSC will not operate normally which could lead to an unexpected accident. Therefore, if the DSC HU/CM or SAS control module is replaced and removed/installed, always perform the initialization of the sensors for DSC-related parts so that the DSC will operate normally.

When using M-MDS

Note

•  Perform initialization on the sensors shown in the following table according to the part to be replaced and removed/installed.

Replacement and removed/installed part	Initialization items
	Brake fluid pressure sensor	Lateral acceleration speed sensor	Yaw rate sensor	Longitudinal acceleration speed sensor
DSC HU/CM	Implement	Implement	Implement	Implement
SAS control module	−	Implement	Implement	Implement

1.  Inspect the wheel alignment, tire pressure. (See FRONT WHEEL ALIGNMENT.) (See REAR WHEEL ALIGNMENT.) (See WHEEL AND TIRE SPECIFICATION.)

•  If there is any malfunction, adjust the applicable part.

2.  Park the vehicle on level ground.

3.  Connect the M-MDS to the DLC-2.

4.  After vehicle identification is completed, select the following from the M-MDS initial screen.

1.  Chassis

2.  ABS/DSC

3.  Sensor initialization

5.  Then, select the following from the screen menu.

•  Brake fluid pressure sensor

•  Lateral acceleration speed sensor

•  Yaw rate sensor

•  Longitudinal acceleration speed sensor

6.  Perform the servicing following the instructions on the screen.

7.  Drive the vehicle.

8.  Drive the vehicle for 5 min or more and verify that there is no malfunction in the DSC system.

When not using M-MDS

Note

•  Depending on the nature of the work performed prior to implementing the initialization, a warning light may be illuminated.

1.  Inspect the wheel alignment, tire pressure. (See FRONT WHEEL ALIGNMENT.) (See REAR WHEEL ALIGNMENT.) (See WHEEL AND TIRE SPECIFICATION.)

•  If there is any malfunction, adjust the applicable part.

2.  Park the vehicle on level ground.

3.  Switch the ignition ON (engine off) and wait for 30 s or more.

4.  With your left foot depressing the brake pedal, perform the following procedure within 30 s.

(1)  Operate the electric parking brake. (Brake system warning light turns on)

(2)  Depress the accelerator pedal fully 2 times.

(3)  Release the electric parking brake. (Brake system warning light turns off)

(4)  Perform the same procedure one more time.

5.  Release your foot from the brake pedal.

Note

•  Depending on the nature of the work performed prior to implementing the initialization, a warning light may be illuminated.

6.  After 2 s, verify that the following warning lights/indicator lights turn off after approx. 3 s.

•  Brake system warning light

•  ABS warning light

•  TCS/DSC indicator light

•  TCS OFF indicator light (Without Off-Road Traction Assist)

•  Off-Road Traction Assist indicator light (With Off-Road Traction Assist)

―  If each warning light/indicator light does not turn on/off, switch the ignition off and repeat the procedure from the beginning.

7.  Switch the ignition off.

8.  Drive the vehicle.

9.  Drive the vehicle for 5 min or more and verify that there is no malfunction in the DSC system.
