Here’s a step-by-step guide to troubleshooting and resolving this issue

 Check the Information Screen:

1. Navigate to the information screen on your controller by scrolling with the arrow button locate the screen labeled FUSE, DRIVE, MOTOR screen.
2. Verify that the MOTOR, FUSE, and DRIVE cells are all ticked.
   

• If you see an ‘x’, question mark, or any symbol other than a tick, it indicates a fault.

 Confirm Proper Gate Engagement

1. If all cells are ticked but the error persists, check if the gate is properly engaged.
2. Disengage the gate and manually push it open and closed to ensure smooth operation.
   
   • If there is any obstruction, resolve it before proceeding.

MOTOR Cross Troubleshooting:

• Check that the motor terminals are securely connected to the controller.
• Inspect the green motor connection block for damage or melting. Replace it if necessary.
• Test the motor:
  
  1. Disconnect the motor terminals from the controller.
  2. Connect the motor terminals directly to a battery to test functionality.
  3. If the motor does not run, the commutator might be faulty. Take the motor to your nearest Centurion branch for testing and possible repairs.

A cross under the DRIVE section  (e.g., Q1, Q2, Q3, Q4):

• This indicates damage to the H-bridge on the controller.
• The display will specify the affected part (e.g., Q1Q3, Q2Q4).
• Take the controller board to your nearest Centurion branch for testing and possible repairs.

A cross under the FUSE Section :

• Inspect the green ATO 30A fuse with a continuity tester.
• Ensure it is making good contact in the fuse holder.
• If the fuse is blown, replace it to resolve the issue.

 Consider Additional Causes

If all cells are ticked, and the gate operates smoothly, but the error persists, consider these additional factors:

1. Battery Check:

   • Test the battery under load to ensure it provides the correct voltage.
   • In rare cases, a low battery can cause motor faults. Replace the battery if necessary.

2. Oil in the DOSS Chamber of D5 EVO or DOSS fault: 

   • Oil leakage in the DOSS chamber can trigger this issue.
   • Refer to the DOSS Chamber Oil Check article for detailed steps on how to inspect and resolve this.
