Suspension Control ( Automatic - Electronic ): Service and Repair

SUSPENSION FLUID (KDSS)
BLEEDING

NOTICE:
^ Ensure that the reservoir tank of the SST is sufficiently filled with suspension fluid. Keep the suspension fluid at a reasonable level to prevent air from entering the SST hose.
^ Do not reuse suspension fluid. Use only specified fluid: Suspension fluid AHC.
^ Do not push the pin on the oil nozzle valve sub-assy in with a tool.

1. REMOVE RADIATOR SUPPORT SEAL UPPER
2. REMOVE BATTERY
3. REMOVE STEP SUB-ASSY LH
4. REMOVE ENGINE UNDER COVER SUB-ASSY NO.1

5. SEPARATE STABILIZER BAR FRONT
a. Using a socket hexagon wrench (10 mm), remove the 4 bolts and 2 front stabilizer lower brackets and separate the stabilizer bar front.

HINT: Separate the stabilizer bar front so that the air in the front stabilizer w/ tube cylinder assy can be bled out easily when bleeding the hydraulic circuits.

6. REMOVE SPARE DISC WHEEL

7. SEPARATE STABILIZER BAR REAR
a. Using a socket hexagon wrench (8 mm), remove the 4 bolts and 2 rear stabilizer brackets lower and separate the stabilizer bar rear.

HINT: Separate the stabilizer bar rear so that the air in the rear stabilizer control cylinder can be bled out easily when bleeding the hydraulic circuits.

8. BLEED SUSPENSION FLUID
a. Fill the reservoir tank of the SST with suspension fluid. Fluid: Suspension fluid AHC
SST 09760-60010

b. Connect the SST joints to the oil nozzle valves.

HINT: The SST joints can be connected to either of the oil nozzle valves.

c. Loosen the 2 stabilizer control adapter shutter valves.
Distance between A and B: 15 to 16.5 mm (0.60 to 0.65 inch) or less

NOTICE:
^ Do not excessively loosen the valves.
^ Ensure that all the bleeder plugs are tightened.

d. Set a wrench, vinyl tube and reservoir tank to the bleeder plug.

HINT: Perform the following refill and air bleeding procedures in the same way for each bleeder plug.

e. Bleed any air out of the suspension fluid between the SST and stabilizer control w/ bracket valve assy.
1. Boost the fluid pressure to 5 MPa, loosen the bleeder plug, bleed air and tighten the plug.
Torque: 9.5 Nm (97 kgf-cm, 84 inch lbs.)
2. Perform the procedure for A shown in the illustration first, then for B.
f. Add suspension fluid to each unit.
1. Loosen the bleeder plug, add suspension fluid until air stops coming out and tighten the bleeder plug.
Torque: 9.5 Nm (97 kgf-cm, 84 inch lbs.)

NOTICE: Perform the operations in the following order: A, B, C, D, E and F.

HINT:
^ Ensure that only 1 bleeder plug is loose when adding suspension fluid.

^ Perform the procedures with the front and rear cylinders fully stretched downward.
Length of cylinder:
A: 411.5 to 417.5 mm (16.20 to 16.44 inch)
B: 436.5 to 442.5 mm (17.19 to 17.42 inch)
g. Bleed any air out of the suspension fluid in each unit.
1. Boost the fluid pressure to 7 MPa, loosen the bleeder plug, bleed air and tighten the plug. Repeat the procedure until air stops coming out.
Torque: 9.5 Nm (97 kgf-cm, 84 inch lbs.)

NOTICE:
^ Do not boost the fluid pressure to 8 MPa or more.
^ Perform the operations in the following order: A, B, C, D, E and F.

HINT:
^ The procedure is complete when air does not come out twice in succession.

a. Support the stabilizer bar front with a jack. Place a wood en block between the jack and the stabilizer bar front to prevent damage.

HINT: Place the jack under the left side of the vehicle.

b. Using a socket hexagon wrench (10 mm), connect the stabilizer bar front with the 4 bolts and 2 front stabilizer lower brackets.
Torque: 59 Nm (602 kgf-cm, 44 ft. lbs.)
10. CONNECT STABILIZER BAR REAR

a. Support the stabilizer bar rear with a jack. Place a wooden block between the jack and the stabilizer bar rear to prevent damage.

HINT: Place the jack under the left side of the vehicle.

b. Using a socket hexagon wrench (8 mm), connect the stabilizer bar rear with the 4 bolts and 2 rear stabilizer brackets lower.
Torque: 50 Nm (510 kgf-cm, 37 ft. lbs.)
11. STABILIZE SUSPENSION
a. Lower the vehicle.
1. Place the 4 wheels on the ground with the SST connected.

NOTICE:
^ Pay attention to the SST while lowering the vehicle.
^ Ensure that the jack and lift are completely separated from the vehicle.

b. Set charging pressure to within the specified range.
1. Charge suspension fluid with the SST
Specified charging pressure:
2.60 to 3.00 MPa at 20°C (68°F) (Fluid temperature)
2.90 to 3.40 MPa at 35°C (95°F) (Fluid temperature)
c. Stabilize the vehicle.
1. Do not perform any operations on the vehicle for 30 seconds or more after charging suspension fluid. The vehicle will stabilize during this time.

12. CHECK SUSPENSION FLUID PRESSURE
a. Check the suspension fluid pressure.
13. MEASURE VEHICLE HEIGHT
a. Measure the difference in vehicle height between the left and right sides.
1. For measurement procedures, refer to Suspension Control ( Automatic - Electronic Level ); Testing and Inspection.

b. Tighten the stabilizer control adapter shutter valves.
Torque: 14 Nm (140 kgf-cm, 10 ft. lbs.)
c. Disconnect the SST joints.

NOTICE:
^ Ensure that the stabilizer control adapter shutter valves are completely closed before disconnecting the SST joints.
^ Ensure that no pressure is applied to the SST hoses before disconnecting the SST joints.
