Description:

This diagnostic trouble code is triggered when an internal fault occurs in the UIM control unit. This indicates that the control unit has detected an internal error that affects its normal operation.

Reaction:

When this code is detected, the control unit may not function correctly, leading to erratic behavior or complete failure of certain systems. The equipment may enter a limp mode or protective state to prevent further damage.

Recommendations:

Reset Control Unit:

• Attempt to reset the control unit by disconnecting the power source for a few minutes and then reconnecting it. This can sometimes clear temporary faults.

Inspect Control Unit Connections:

• Check all connections to the control unit for signs of damage, corrosion, or looseness. Ensure that all connections are secure and in good condition.

Reprogram or Replace Control Unit:

• If resetting and inspecting connections do not resolve the issue, consider reprogramming the control unit if possible. If the control unit is damaged, replacement may be necessary.

Consult Technical Support:

• Due to the complexity of internal control unit faults, consult technical support or the manufacturer for detailed diagnostic procedures and potential replacement of the control unit.

Note:

Internal control unit faults can lead to significant disruptions in equipment operation. It is crucial to address these issues promptly to restore normal functionality. Regular updates and maintenance of the control unit firmware and software can help prevent such faults.
