Suspension Control System (w/ Air Suspension)

SUSPENSION CONTROL: SUSPENSION CONTROL SYSTEM (w/ Air Suspension): ON-VEHICLE INSPECTION

1. INSPECT TIRES Component Tests and General Diagnostics

2. ADJUST STANDARD VEHICLE HEIGHT

(a) Release the parking brake and stabilize the suspension by bouncing the corners of the vehicle.

(b) With the shift lever in N, settle the tires by moving the vehicle back and forth.

(c) Start the engine.

(d) Operate the height control switch to raise and then lower the vehicle height. Perform this operation twice.

NOTICE:
Be sure to release the parking brake and move the shift lever to N.

3. INSPECT VEHICLE HEIGHT Front Wheel Alignment

4. INSPECT VEHICLE HEIGHT SELECTION Air Suspension System

5. ADJUST VEHICLE HEIGHT

NOTICE:
While adjusting vehicle height, do not put anyone or anything on or in the vehicle because doing so will affect vehicle height.

(a) Suspend vehicle height control by pressing the height control switch.

(b) Put the vehicle on a level surface.

(c) Measure the vehicle height (C - D measurement) on the right side and left side.





Standard vehicle height:

Front Wheel Alignment

Difference between right and left side:

10 mm (0.394 in.) or less

(d) If the actual vehicle height differs from the vehicle height (C - D measurement), adjust it by jacking up the frame, etc. (Procedure "A").

(e) If the procedure "A" differs from the vehicle height (C - D measurement), adjust it by following the procedures below.





(1) Loosen the nut.

(2) Move the height control sensor link up and down along the slotted hole of the bracket.

(3) Adjust the vehicle height to the vehicle height (C - D measurement) while checking the value on the Techstream or voltmeter.

(4) Tighten the nut.

Torque : 5.4 Nm (55 kgf-cm, 48 in-lbf)

(f) If the vehicle height cannot be adjusted by performing procedure "A", adjust it again by following the procedures below.

(1) Loosen the 2 lock nuts of the height control sensor link.

(2) Adjust the vehicle height to the vehicle height (C - D measurement) by turning the link while checking the value on the Techstream or the voltmeter.

HINT
The vehicle height will be changed by approximately 3.0 mm (0.118 in.) when changing the link by approximately 2 mm (0.0787 in.).

(3) Tighten the 2 lock nuts.

Torque : 5.4 Nm (55 kgf-cm, 48 in-lbf)

(g) Check that the lengths of the screw parts, labeled "A" in the illustration, are within the standard values.

Standard Length:





(h) Change the vehicle height (from the normal position to the high position, and from the high position to the normal position).

(i) Measure the vehicle height (C - D measurement) on the right and left side (Procedure "D").

(j) Check if the vehicle height (C - D measurement) is within the specified range.

HINT
If the values are outside the standard range, perform the procedures from procedure "A" to procedure "D" again.
