Description:

This error code, XSC 523218.04, indicates that the supply voltage (BAT) at pin J2M4 has dropped below 9 volts. This low voltage condition can affect the control software’s ability to function properly.

Reaction:

When this fault occurs, the control software will exhibit limited or no functionality, impacting the overall operation of the vehicle’s electronic systems.

Recommendations:

Inspect Battery and Connections:

• Check the vehicle’s battery for proper charge and condition.
• Ensure all battery connections are clean, secure, and free from corrosion.

Monitor Voltage Levels:

• Use diagnostic tools to monitor the voltage levels at pin J2M4 in real-time.
• Identify and correct any deviations from the normal operating range.

Check Wiring and Connectors:

• Inspect the wiring and connectors associated with pin J2M4 for any signs of damage, corrosion, or loose connections.
• Ensure all connections are secure and properly terminated.

Test Charging System:

• Verify that the vehicle’s charging system is functioning correctly and providing adequate voltage to the battery.

Consult Technical Support:

• If the issue persists, contact John Deere technical support for further diagnostics and solutions.
• Provide detailed logs of voltage readings and any steps already taken to address the fault.

Note:

Maintaining proper battery voltage is crucial for the reliable operation of the control software and overall vehicle systems. Regular inspections and maintenance of the battery and electrical system can help prevent such faults.
