PRECAUTION (BRAKES)A6E691001020201Wheels and Tires Removal/Installation
1. The removal and installation procedures for the wheels and tires are not mentioned in this section. When a
wheel is removed, tighten it to 88—118 N·m {9.0—12.0 kgf·m, 65.0—87.0 ft·lbf}.
Brake Lines Disconnection/Connection
Caution
•Brake fluid will damage painted surfaces. If brake fluid does get on a painted surface, wipe it off
immediately.
1. Tighten the brake pipe flare nut using the SST (49 0259 770B). Be sure to modify the brake pipe flare nut
tightening torque to allow for use of a torque wrench-SST combination.
•If any brake line has been disconnected anytime during the procedure, add brake fluid, bleed the brakes,
and inspect for leakage after the procedure has been completed.
Connectors Disconnection
1. Disconnect the negative battery cable before doing any work that requires handling of connectors. Reconnect
the negative battery cable only after the work is completed.
ABS, ABS/TCS, or DSC Components Operations
1. Make sure that there are no DTCs in the ABS, ABS/TCS, or DSC memory after working on ABS, ABS/TCS or
DSC components.
•If there are any DTCs in the memory, clear them.

PARKING BRAKE (LEVER TYPE) ADJUSTMENTA6E6914440002011. Start the engine and depress the brake pedal several times.
2. Stop the engine.
3. For the 2WD model, remove the rear ashtray case behind the center console
4. For the 4WD model, remove the 4 screws (back side) and pull up the rear of the center console, then remove
the rear ashtray case.
5. Turn the adjusting nut as shown in the figure.
6. After adjustment, inspect the following points:
(1) Turn the ignition switch to ON, pull the parking
brake lever one notch, and verify that the
parking brake warning light illuminates.
(2) Verify that the rear brakes do not drag.

DSC HU/CM INSPECTIONA6E6920676502041. Remove the battery and battery bracket.
2. Disconnect the DSC HU/CM connector.
3. Connect the SST (49 G066 004) to the DSC HU/CM connector and harness side connector.
4. Inspect voltage referring the table below.
