FRONT CORNER (LEFT OR RIGHT) RAISES IN SPRUNG, BUT NOT UNSPRUNG MODE - Continued
STEP
12.
Perform No. 1 actuator pressure test (port 3) using HDC.
a.
Stop engine; relieve hydraulic pressure.
b.
Reset all HDC solenoid valves by selecting RESET VALVES button (Figure 9, Item 2) on HDC control
box.
NOTE
This test is performed at No. 1 actuator of front corner which will not raise.
c.
Start engine. Place SPRUNG/UNSPRUNG lever in SPRUNG. Move (right or left, as applicable)
SUSPENSION CONTROL lever to RAISE.
d.
Read transducer T-5 (front right actuator) or T-6 (front left actuator) hydraulic pressure on HDC display
(Figure 9, Item 1).
e.
Stop engine; relieve hydraulic pressure.
CONDITION/INDICATION
Is transducer T-5 (front right actuator) and T-6 (front left actuator) hydraulic pressure greater than 3,000 psi
(20,685 kPa)?
DECISION
YES - Go to Step (15).
NO - Go to Step (13).
STEP
13.
Perform solenoid valve V15/V16 test.
a.
Reset all HDC solenoid valves by selecting RESET VALVES button (Figure 9, Item 2) on HDC control
box.
b.
Start engine.
c.
Wait until transducer T-1 hydraulic pressure on HDC display (Figure 9, Item 1) is less than 500 psi
(3,447.379 kPa).
d.
Move SUSPENSION CONTROL lever (left-hand or right-hand lever, as applicable) to RAISE.
e.
Read transducer T-1 hydraulic pressure on HDC display (Figure 9, Item 1).
