Description:

This error code, EPC 001079.02, is generated when the control unit detects several incorrect output signals from the 5-volt components (clutch pedal potentiometer B65, accelerator pedal potentiometer B79, hand throttle potentiometer B96, and enable pressure sensor B105). This indicates a problem with the 5-volt power supply.

Reaction:

When this error is detected, the affected components may not function correctly, leading to potential issues with the clutch, accelerator, hand throttle, and pressure sensor operations. The diagnostic trouble code triggers the alarm level “Information”.

Recommendations:

Inspect 5-volt Power Supply:

• Check the 5-volt power supply circuit for any signs of faults or irregularities. Ensure that the power supply is stable and within the specified range.

Verify Wiring and Connections:

• Inspect the wiring and connections to the 5-volt components (B65, B79, B96, B105) for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.

Test Affected Components:

• Use diagnostic tools to test the clutch pedal potentiometer, accelerator pedal potentiometer, hand throttle potentiometer, and enable pressure sensor for proper functionality.

Check for Short Circuits:

• Look for any short circuits in the wiring that could be causing incorrect output signals. Repair any detected faults.

Reset and Test System:

• After addressing the issues, reset the system and monitor the output signals from the 5-volt components to ensure they are within the normal operating range.

Note:

Maintaining a stable and reliable 5-volt power supply is crucial for the proper functioning of various components. Regular inspection and maintenance of the power supply circuit can help prevent such issues.
