New Holland 19092 – New Holland Dosing Control Unit Dcu: High Supply Voltage for Dosing Module

The system has detected a high supply voltage for the dosing module. This condition may affect the operation of the dosing valve or pump motor. The voltage is above the lower limit specified for the system.

1. 1

   Supply voltage to the dosing module

2. 2

   Dosing valve or pump motor circuit

3. 3

   VDD11/VDD25 voltage monitoring circuit

1. 1

   Verify the supply voltage to the dosing module using a multimeter.

   Measure the voltage at the connection point of the dosing module to ensure it is within the acceptable range.

2. 2

   Inspect the wiring and connections to the dosing valve or pump motor.

   Check for any signs of damage, corrosion, or loose connections that could cause voltage irregularities.

3. 3

   Check the VDD11/VDD25 voltage monitoring circuit.

   Ensure that the circuit responsible for monitoring the voltage is functioning correctly and not providing false readings.
