4. Transducer T7, T8, T9, T10, T11, T12, and T13 check:
a) Have the vehicle operator move the SPRUNG/UNSPRUNG lever to the UNSPRUNG position.
b) With the vehicle running, confirm that T7, T8, T9, T10, T11, T12, and T13 read greater than 2500 psig.
(This is the pressure provided by the compensating pump, and it indicates that transducers T7 through
T13 are working properly.)
5. Transducer T5 check:
a)
Push the RESET VALVES button on the control box, and verify all the valves are set to the power OFF
setting and are in the default position. Reference Table A--1.
b)
Verify that the SPRUNG/UNSPRUNG lever is in the UNSPRUNG position.
c)
Have the vehicle operator move the right SUSPENSION CONTROL lever to the RAISE position, and
hold it there until the vehicle reaches the maximum height.
d)
Verify that the pressure reading for T5 is at least 2,800 psig. (T5 is now reading the pressure setting of
the right suspension relief valve, and indicates that transducer T5 is working properly.)
e)
Have the vehicle operator release the right SUSPENSION CONTROL lever.
