Description:

This code is logged when an actuator signal exceeds the maximum expected value, likely due to a short to 12 volts. This issue may pertain to any actuator within the system, such as those controlling emissions, throttle, or fluid levels, potentially causing erratic or unintended actuator behavior.

Reaction:

The control software may deactivate the affected actuator or adjust its operation to prevent damage or unsafe conditions.

Recommendations:

• Identify Affected Actuator: Determine which actuator is reporting high signal values using diagnostic tools.
• Inspect Electrical Circuit: Look for damaged wires or connections that could cause a voltage short.
• Repair Electrical Short: Fix any identified shorts and ensure all connections are secure.
• Reset ECU and Conduct Tests: After addressing the fault, reset the ECU and perform a comprehensive test to ensure all actuators operate within their designated signal ranges.

Note:

Maintaining proper signal integrity for all actuators is essential for vehicle safety and operational efficiency. Regular electrical system checks can prevent signal faults and preserve system functionality.
