336
LIFT DOWN VALVE - OPEN
CIRCUIT
The power module did not detect cur-
rent flow to the lift down solenoid during
normal operation. (J2-16 NDV)
• Check for continuity through this circuit. The lift down solenoid
resistance should measure about 20 Ohms. The lift down sole-
noid is powered (PWM) by ground board, and its ground is to
ground board.
• Inspect the wiring for physical damage.
• Replace ground board.
• HEALTH (Status LED) - ON
337
STEER LEFT VALVE - SHORT
TO BATTERY
Voltage from an external source was
detected on the Steer Left Solenoid (J2-
9 NLV).
• Check for continuity through this circuit. Steer left solenoid resis-
tance should measure about 30 Ohms. The steer left solenoid is
powered with 24V from ground board J2-1, and its ground is to
ground board J2-9.
• Inspect the wiring for physical damage.
• Replace ground board.
• HEALTH (Status LED) - ON
338
STEER LEFT VALVE - OPEN
CIRCUIT
Current flow to the Steer Left Solenoid
was not detected (J2-9 NLV).
• Check for continuity through this circuit. Steer left solenoid resis-
tance should measure about 30 Ohms. The steer left solenoid is
powered with 24V from ground board, and its ground is to ground
board.
• Inspect the wiring for physical damage.
• Replace ground board.
• HEALTH (Status LED) - ON
339
STEER RIGHT VALVE -
SHORT TO BATTERY
Voltage from an external source was
detected on the Steer Left Solenoid (J2-
18 NRV).
• Check for continuity through this circuit. Steer right solenoid
resistance should measure about 30 Ohms. The steer right sole-
noid is powered with 24V from ground board J2-1, and its ground
is to ground board J2-18.
• Inspect the wiring for physical damage.
• Replace ground board.
• HEALTH (Status LED) - ON
3310
STEER RIGHT VALVE - OPEN
CIRCUIT
Current flow to the Steer Right Solenoid
was not detected (J2-18 NRV).
• Check for continuity through this circuit. Steer right solenoid
resistance should measure about 30 Ohms. The steer right sole-
noid is powered with 24V from ground board, and its ground is to
ground board.
• Inspect the wiring for physical damage.
• Replace ground board.
• HEALTH (Status LED) - ON
3312
LEFT BRAKE - SHORT TO
BATTERY
Voltage from an external source was
detected on the Left Brake Solenoid (J1-
34 NLB).
• Check for continuity through this circuit. The left brake is powered
with 24V from ground board J1-29, and its ground is to ground
board J1-34. Brake solenoid resistance should measure about 20
Ohms.
• Inspect the wiring for physical damage.
• Replace ground board.
3313
RIGHT BRAKE SHORT TO
BATTERY
Voltage from an external source was
detected on the Right Brake Solenoid
(J1-33 NRB).
• Check for continuity through this circuit. Brake solenoid resis-
tance should measure about 20 Ohms. The right brake is powered
with 24V from ground board J1-30, and its ground is to ground
board J1-33.
• Inspect the wiring for physical damage.
• Replace ground board.
