Showing 25 of 25 fault codes

Code	Description	Solution	Guide
01	Ground Controller MC2M Hardware Fault	Try to restart the power supply. Check the external wiring and power supply of the controller. Measure voltage between S1 and S21 pins (should be ~12V). Measure bus resistance between S23 and S25 pins (should be 60-120Ω). Replace ground controller if fault persists.	View Guide
02	Ground Controller MC2M Communication Error	Restart power supply. Check CAN bus wiring for damage or loose connections. Verify controller wiring harness. If fault persists after checking wiring, replace ground controller.	View Guide
03	Ground Controller MC2M System Error	Check controller harness connections. Verify 12V power supply to controller. Inspect CAN bus termination resistors. Replace ground controller if fault cannot be cleared.	View Guide
04	Ground Controller MC2M Internal Fault	Power cycle the machine. Check for water ingress in controller housing. Inspect all connector pins for corrosion. Replace controller if internal fault persists.	View Guide
05	Platform Controller MC2M Hardware Fault	Restart power supply. Check external wiring and power supply of platform controller. Measure voltage between S1 and S21 pins (should be ~12V). Check bus resistance between S23 and S25 pins (60-120Ω). Replace platform controller if needed.	View Guide
06	Platform Controller MC2M Communication Error	Check platform controller CAN bus wiring. Verify harness connections through boom and turret. Inspect slip ring connections for continuity. Replace platform controller if fault persists.	View Guide
17	Machine Mode Not Selected	Internal controller selection parameters are abnormal. Access controller settings to verify correct machine model is selected. Contact Dingli service for OEM password access.	View Guide
18	Chassis Tilt Alarm (Vehicle Tilted)	Warning that the vehicle is currently tilted beyond safe operating angle. Move machine to level ground. If on level ground, recalibrate chassis tilt sensor in diagnostic menu. Check tilt sensor wiring and mounting.	View Guide
21	Left Axle Lock Feedback Error (Power On)	Check wiring harness and connector of the left floating cylinder solenoid valve for damage. Inspect left oscillating axle lock valve block. Replace left floating valve block if faulty. Replace controller if valve tests normal.	View Guide
22	Right Axle Lock Feedback Error (Power On)	Check wiring harness and connector of the right floating cylinder solenoid valve for damage. Inspect right oscillating axle lock valve block. Replace right floating valve block if faulty. Replace controller if valve tests normal.	View Guide
23	Bypass Mode Active	Warning that bypass/override function is currently enabled. This allows operation despite certain safety restrictions. Verify bypass switch is in correct position. Use bypass only for recovery operations.	View Guide
24	Engine Hood Safety Switch Open	Engine compartment hood switch is activated. Normal operation limits engine start when hood is open. Running engine will immediately shut down. Close hood and verify switch operation.	View Guide
25	Transport Mode Active	Vehicle is in transport/loading mode. Certain functions like automatic platform leveling are disabled. Switch to operating mode for normal boom functions.	View Guide
26	Left Axle Lock Feedback Error (Power Off)	Check left floating cylinder solenoid valve wiring. Inspect valve block for stuck solenoid. Verify hydraulic supply to axle lock circuit. Replace left floating valve block or controller.	View Guide
27	Right Axle Lock Feedback Error (Power Off)	Check right floating cylinder solenoid valve wiring. Inspect valve block for stuck solenoid. Verify hydraulic supply to axle lock circuit. Replace right floating valve block or controller.	View Guide
28	Turret Proximity Switch Error	Logical conflict detected between turret proximity switches. Check the three proximity switches in the turntable via diagnostic interface. Verify switch power supply voltage. Inspect switch harness and connectors. Replace abnormal proximity switch.	View Guide
29	Bypass Input Detected	Bypass switch on ground or platform controller is activated. If switch is not operated, check for short circuit in bypass switch wiring. Replace ground or platform controller if switch circuit is faulty.	View Guide
30	Platform Overload Alarm	Platform weight exceeds rated load capacity. Remove excess weight from platform immediately. If alarm persists with empty platform, recalibrate load cells. Check for load cell damage or wiring issues.	View Guide
31	Engine Fault Detected	Engine requires service. Check specific engine fault code in the Engine Alarm menu of diagnostic interface. Refer to engine manufacturer fault code list. Common causes: oil pressure, coolant temp, emissions system.	View Guide
32	PVG Proportional Valve Block Fault	Restart power supply. Check PVG valve block harness and connectors. Verify valve block power supply is normal. Check all PVG solenoid valve LED indicators (should be green). Use 9mm wrench to manually cycle stuck valve spools. Replace PVG valve block if fault persists.	View Guide
36	Movement Joystick Initialization Fault	Joystick did not initialize properly after power-up. Ensure joystick is in neutral position during startup. Restart system with joystick centered. Check joystick wiring. Replace joystick if initialization consistently fails.	View Guide
37	Articulating Boom Extension Restricted	Articulating boom extend-out is restricted due to radius limit or sensor fault. Check articulating boom angle sensor. Verify platform position is within envelope. Recalibrate jib angle sensor if on level ground with stowed boom.	View Guide
46	Movement Joystick Fault	Movement joystick signal is invalid. Check joystick wiring harness for damage. Verify joystick connector pins. Test joystick signal in diagnostic menu. Replace joystick assembly if signal is erratic.	View Guide
51	Main Boom Extension Restricted	Main boom telescope extension is restricted. Machine has reached maximum horizontal outreach for current boom angle. Lower boom to increase allowable extension. Check boom length sensor calibration.	View Guide
66	Main Boom Position Limit Active	Main boom is restricted to operating range (-55° to 55°). This occurs when articulating sensor or angle redundancy fails. Check boom angle sensors. Verify sensor calibration values.	View Guide
