031 OPEN CIRCUIT
JIB DOWN
The Lower Control has detected an open circuit on the Jib
Down solenoid output when it was energized during
startup self diagnostics.
NOTE: A load of less than 70mA will be detected as an
open circuit. The typical load is approximately 800mA.
Possible causes include:
1. Faulty Jib Down solenoid wiring
2. Faulty Jib Down solenoid
3. Fault Lower Control
1. Repair or replace Jib Down solenoid wiring
2. Replace Jib Down solenoid
3. Replace Lower Control
032 SHORTED CIRCUIT
