4-001 trouble code, how to diagnose this code
1 comments:
Mr. Anderson
May 14, 2025
To diagnose the 4-001 trouble code on the Crescent CS7010:
- Code 4-001 indicates a Drive Controller Timeout. - This is a critical fault meaning the main controller is not receiving heartbeat messages from the drive controller. - Check the communication wiring and connectors between the main controller and the drive controller. - Inspect for loose or damaged cables. - If wiring is intact, the drive controller or main controller may be faulty.

Solution System Chapter Functional Description Overview The CS7010 is an electrically driven system, but with various prime-power configurations. All configurations utilize a 36-volt battery system, but the hybrid models incorporate engine-alternator power generation to constantly charge the batteries. When the engine is running the alternator provides the electrical power to operate the machine electrical loads as well as recharge the battery pack.
Service Manual – CS7010™ 24 - Electrical System Circuit Protection There are several layers of circuit protection. The top level protection is the 400-amp fuse from the main battery pack. The second level protection is the circuit breakers in the operator’s platform. This includes the 5-amp circuit breaker to the main controller, the 25-amp breaker to loads on the main controller, and a 25- amp breaker to the steering system.
Service Manual – CS7010™ 24 - Electrical System Component Locations Battery Interlock or Interlock Jumper Battery powered machines have an interlock switch (proximity sensor), to detect if the battery retaining bar is not lowered into position. If the sensor is open, machine function is disabled to prevent the batteries from shifting in the machine during travel.
