Description:

This error code indicates that the unswitched supply voltage for Selective Control Valve I (SV I) and Selective Control Valve II (SV II) is above 18.0 V. High voltage can cause damage to the valves and other components.

Reaction:

When this code is detected, the SCC will disable its functions, turning them off to prevent potential damage.

Recommendations:

Inspect Voltage Regulator:

• Check the voltage regulator supplying power to SV I and SV II. Replace if it is malfunctioning and allowing the voltage to rise above safe levels.

Check Power Supply:

• Ensure the power supply providing voltage to SV I and SV II is within the specified range. If not, investigate and correct the source of the high voltage.

Inspect Wiring and Connectors:

• Check all wiring and connectors for SV I and SV II for signs of damage, poor connections, or corrosion. Repair or replace as necessary.

Monitor Voltage:

• Use a multimeter to continuously monitor the voltage supplied to SV I and SV II, ensuring it remains within the acceptable range.

Consult Technical Support:

• If the issue persists, contact technical support for further diagnostics and assistance.

Note:

High voltage can severely damage electronic components. Addressing this issue promptly is crucial.
