If here, “CIRCUIT FAULT” message is associated with
a pressure transducer (upper LCD screen display).
Power off HDC system.
Tag the W2 or W3 cable assembly electrical lead to the
hydraulic pressure transducer identified in the
“CIRCUIT FAULT” message and switch electrical leads
with another (or spare) hydraulic pressure transducer.
If a spare of another pressure transducer is not nearby,
temporarily exchange the identified pressure transducer
with another pressure transducer from elsewhere in the
vehicle.
Power up HDC system again.
Does upper LCD screen display the same “CIRCUIT
FAULT” message (identifying the same hydraulic
pressure transducer as the previous “CIRCUIT FAULT”
message)?
75
Power off HDC system.
Replace the applicable HDC system pressure
transducer identified in the first “CIRCUIT
FAULT” message (WP 0031 00, WP 0032 00,
WP 0035 00, WP 0037 00).
If a “good” pressure transducer was switched
with another pressure transducer to check out
the first transducer, make sure the good
transducer is returned to the original location.
Reconnect proper electrical leads and ensure all
W2 or W3 electrical leads are mated with the
proper pressure transducer.
Continue performing HDC system functional
check--out.

Power off HDC system.
If a “good” pressure transducer was switched
with another pressure transducer to check out
the first transducer, make sure the good
transducer is returned to the original location.
Reconnect proper electrical leads and ensure all
W2 or W3 electrical leads are mated with the
proper pressure transducer.
