Question 1

What does Liebherr fault code 0x00B9 B05 mean?

Accepted Answer

0x00B9 B05 (Hydraulics / Crowd Winch): Crowd Winch Function Cut-out or Loss of Precision Control Fix: LOGIC: Crowd Winch High-Pressure Transducer (B05) Signal Voltage Too Low or Circuit Open.

ACTION: Locate sensor B05 on the crowd winch valve block or motor manifold. Test for the +4V reference power and ground at the harness plug. If power is good, check the signal return wire back to the controller. Replace the B05 transducer if the signal line reads dead 0V under key-on conditions.

Question 2

What does Liebherr fault code 0x00C2 mean?

Accepted Answer

0x00C2 (Hydraulics / Winch): Main Rotary (DKR) / Kelly Winch Stall Fix: LOGIC: Main Winch Proportional Pressure Solenoid Circuit Open.

ACTION: Measure solenoid coil resistance at the winch control block (X10 plug). Inspect harness flex points around the mast swivel joint for wire strain or insulation chafing.

Question 3

What does Liebherr fault code 0x00C4 mean?

Accepted Answer

0x00C4 (Hydraulics / Winch): Kelly Winch Inoperative / Lockout Active Fix: LOGIC: Main Winch Proportional Pilot Solenoid Current Below Normal (Open Circuit).

ACTION: Measure solenoid coil resistance at the main winch manifold block. Inspect harness flex points around the mast swivel joint for wire strain or broken pins.

Question 4

What does Liebherr fault code 0x0114 mean?

Accepted Answer

0x0114 (Hydraulics / Slew): Upper Carriage Slew Locked / Drift Alarm Fix: LOGIC: Slew Gearbox Hydraulic Holding Brake Solenoid Circuit Open.

ACTION: Disconnect multi-disc brake release solenoid on the swing drive reduction box. Measure coil resistance (spec: ~24Ω). Check 24V supply output from Litronic driver module +4A1-A1 pinout.

Question 5

What does Liebherr fault code 0x0141 mean?

Accepted Answer

0x0141 (Hydraulics / Rotary): Rotary Torque Drops / Slow Rotation Fix: LOGIC: Rotary Drive Displacement Control Solenoid Signal Out of Range.

ACTION: Measure proportional solenoid resistance on the BAT 300 rotary top-drive manifold. Inspect harness leads running up the mast cable track for pin strain.

Question 6

What does Liebherr fault code 0x015A mean?

Accepted Answer

0x015A (Hydraulics / Winch): Winch Down Speed Limited / Creep Fix: LOGIC: Dragline / Clamshell Winch Secondary Holding Brake Pressure Low.

ACTION: Measure pilot pressure at the mechanical brake release port with a 0–60 bar gauge. Inspect the proportional brake release solenoid valve on the winch base block for foreign contamination.

Question 7

What does Liebherr fault code 0x01D8 mean?

Accepted Answer

0x01D8 (Hydraulics / Main): Engine Severe Lugdown / Black Smoke Fix: LOGIC: Main Hydraulic Pump 1 Displacement Electronic Control Valve Stuck On.

ACTION: Inspect proportional pressure reducing valve (PPRV) spool on Rexroth A4VSO pump regulator for metal slivers or varnish. Measure solenoid driver current under neutral standby.

Question 8

What does Liebherr fault code 0x0205 mean?

Accepted Answer

0x0205 (Hydraulics / Track): Undercarriage Retract / Extend Dead Fix: LOGIC: Telescopic Undercarriage Lock Valve Solenoid Circuit Fault.

ACTION: Inspect undercarriage solenoid valve block mounted inside the lower chassis frame. Measure coil resistance and check for pinched wires near track slides.

Question 9

What does Liebherr fault code 0x021B mean?

Accepted Answer

0x021B (Hydraulics): Rotary Drive BAT 300 No High-Speed Fix: LOGIC: Rotary Drive Dual-Displacement Shift Solenoid Open Circuit.

ACTION: Measure displacement shift solenoid coil resistance on the top-drive hydraulic manifold (~24Ω). Inspect umbilical cable track running along the vertical leader mast for pulled pins.

Question 10

What does Liebherr fault code 0x028A mean?

Accepted Answer

0x028A (Hydraulics): Main Shovel Digging Force Weak Fix: LOGIC: Main Working Pump Swashplate Angle Feedback Deviation.

ACTION: Inspect dual rotary angle position transducers mounted on the main Rexroth A4VSO pump heads. Check 24V power supply and recalibrate swashplate zero/span via Litronic.
