Description:

This error code, EPC 001079.04, is generated when the EPC measures less than 4.8 volts at the positive lead of the power supply to the 5-volt components (clutch pedal potentiometer B65, accelerator pedal potentiometer B79, hand throttle potentiometer B96, and enable pressure sensor B105). This indicates a short to ground in the circuit.

Reaction:

When this error is detected, the affected components may not receive sufficient voltage, leading to malfunction or reduced performance of the clutch, accelerator, hand throttle, and pressure sensor operations.

Recommendations:

Inspect for Short to Ground:

• Check the 5-volt power supply circuit for any signs of shorting to ground. Repair any detected faults.

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 Power Source:

• Ensure that the power source providing the 5-volt supply is stable and functioning correctly. Repair or replace the power source if necessary.

Reset and Test System:

• After addressing the issues, reset the system and monitor the voltage levels to ensure they remain within the normal operating range.

Note:

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