Scheme 8

1. Pull the lock lever up in the direction of the arrow.
2. Pull the connector toward the vehicle rear and remove it.

Scheme 9

1. Place an alignment mark on the brake pipes and DSC HU/CM.
2. Apply protective tape to the connector to prevent brake fluid from entering.
3. Remove the brake pipes.

Brake Pipe (DSC HU/CM-brake pipe joint) Installation Note

1. Align with the mark made before removing the brake pipes and temporarily install the brake pipes to the DSC HU/CM. CAUTION: If the brake pipes is tightened to the specified torque, it may be difficult to install it to the vehicle. Therefore, only temporarily tighten the brake pipes so that it can still be moved.

Scheme 10

1. Align the marks made before removal and install the brake pipes to the DSC HU/CM and brake pipe joint referring to the illustration.
2. Tighten the brake pipes to the specified torque.

Scheme 11

1. After connecting the connector, verify that the lock lever is completely pushed in.

FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION

1. Remove or install the front ABS wheel-speed sensor in the same order of vehicles with ABS. (See «FRONT ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION»(ref-430295-S11526097812011101700000) )

REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION

1. Remove or install the rear ABS wheel-speed sensor in the same order of vehicles with ABS. (See «REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION»(ref-430295-S06469838272011101700000) )

COMBINED SENSOR REMOVAL/INSTALLATION

Scheme 12

1. Remove the console. (See «CONSOLE REMOVAL/INSTALLATION»(ref-430296-S42659527912011101700000) )
2. Remove in the order indicated in the illustration.
3. Install in the reverse order of removal.
4. After installation, perform the combined sensor initialization procedure. (See «STEERING ANGLE SENSOR INITIALIZATION PROCEDURE»(ref-430291-S11560876092011101700000) )

Combined Sensor Connector Installation Note

1. Connect the combined sensor connector to the combined sensor until a click is heard.

Scheme 13

1. Turn the ignition switch to the LOCK position.
2. Connect the M-MDS to the DLC-2.
3. Select the following PIDs, then inspect the lateral acceleration speed and the yaw rate. LAT_ACCL: (lateral acceleration speed) YAW_RATE: (yaw rate) Lateral acceleration speed inspection Verify the LAT_ACCL change when the combined sensor is tilted to the left and right. If there is any malfunction, replace the combined sensor. Standard When the sensor is tilted to the right (A): LAT_ACCL changes negatively. When the sensor is tilted to the left (B): LAT_ACCL changes positively. Yaw rate inspection Verify the YAW_RATE change when the combined sensor is rotated to the left and right. If there is any malfunction, replace the combined sensor. Standard When the sensor is rotated to the right (A): YAW_RATE changes negatively. When the sensor is rotated to the left (B): YAW_RATE changes positively.

STEERING ANGLE SENSOR REMOVAL/INSTALLATION

Note. The steering angle sensor is integrated into the combination switch to ensure sensor performance. Replace the steering angle sensor and combination switch as a single unit. (See COMBINATION SWITCH REMOVAL/INSTALLATION )

Scheme 14

1. Remove the column cover. (See «COLUMN COVER REMOVAL/INSTALLATION»(ref-430296-S08540555702011101700000) )
2. Measure the voltage between steering angle sensor terminal B and ground. If there is any malfunction, inspect the wiring harness between steering angle sensor terminal B and battery, then repair or replace if necessary. Standard voltage B+
3. Turn the ignition switch to the ON position, then measure the voltage between steering angle sensor terminal A and ground. If there is any malfunction, inspect the wiring harness between steering angle sensor terminal A and ignition switch, then repair or replace if necessary. Standard voltage B+
4. Measure the voltage between steering angle sensor terminal H and the ground. If there is any malfunction, inspect the wiring harness between steering angle sensor terminal H and ground point, then repair or replace if necessary. Standard voltage 0V
5. Turn the ignition switch to the LOCK position.
6. Connect the M-MDS to the DLC-2.
7. Select the "SWA_POS" PID.
8. Verify the SWA_POS changes when the steering wheel is turned to the left and right. If there is any malfunction, replace the steering angle sensor. Standard When the steering wheel is turned to the right: SWA_POS changes positively. When the steering wheel is turned to the left: SWA_POS changes negatively.

DSC OFF Switch Connector Removal Note

1. Access the DSC OFF switch connector from behind of the dashboard, and squeeze the tabs of the switch connector.
2. Disconnect the DSC OFF switch connector from the DSC OFF switch.

DSC OFF Switch Removal Note

1. Access the DSC OFF switch from behind of the dashboard, and squeeze the tabs of the switch.
2. Pull the DSC OFF switch towards the driver's side to remove it.

Scheme 15

Scheme 16

1. Remove the DSC OFF switch. (See «DSC OFF SWITCH REMOVAL/INSTALLATION»(ref-430291-S23244253032011101700000) .
2. Verify that the continuity is as indicated in the chart in illustration. If not as indicated in the chart, replace the DSC OFF switch. (See «DSC OFF SWITCH REMOVAL/INSTALLATION»(ref-430291-S23244253032011101700000) )
