Description:

This diagnostic trouble code, PTQ 522847.06, indicates that the circuit current for the proportional solenoid valve for transmission enable is too high, suggesting a short to ground. This error is detected within 200 msec in normal operating mode and 400 msec in come-home mode.

Reaction:

When this error is detected, the control software shifts the transmission to neutral to prevent potential damage.

Recommendations:

Inspect Electrical Connections:

• Check the wiring and connectors associated with the proportional solenoid valve for transmission enable.
• Ensure all connections are secure and free of shorts or damage.

Test Solenoid Valve:

• Use a multimeter to measure the current at the solenoid valve signal input.
• Replace the solenoid valve if it is found to be defective.

Verify Circuit Integrity:

• Inspect the circuit for any signs of shorted connections or damaged wires.
• Repair or replace any identified issues to ensure proper current flow.

Update Software:

• Verify that the control software is up-to-date with the latest version.
• Update the software if there are any available updates to improve system accuracy and error handling.

Monitor System Performance:

• After addressing the above steps, test the proportional solenoid valve to ensure proper functionality.
• Confirm that the current at the signal input is within the specified range during operation.

Note:

• Regular inspection and maintenance of the solenoid valve’s electrical components can prevent high current issues.
• If the issue persists despite taking the above measures, consult technical support or the manufacturer for further assistance.
