APPARENT HYDRAULIC DIAGNOSTIC CENTER (HDC) SYSTEM PROBLEM - Continued
Check if check fails.
Power off HDC system.
Change out HDC system component that did not pass functional check-out with an identical, known good
spare, component (solenoid valve or pressure transducer, as applicable) or temporarily switch identical
type component from another nearby location in HDC system.
Repeat functional test of HDC system components th (WP 0025) .
Did functional check-out test fail again for same component designator as it did for original component in previous
YES - Go to Step (30).
NO - Replace HDC system component (the original solenoid valve or pressure transducer) that did not pass
functional test first time.
Check if CIRCUIT FAULT is a solenoid valve.
Is the CIRCUIT FAULT component that did not pass functional test a solenoid valve?
YES - Go to Step (33).
NO - Go to Step (38).
