Description:

This diagnostic trouble code is generated when the PTA control software detects that the voltage in the positive lead of the park lock solenoid valve 1 is above 12V, indicating a short to a supply lead.

Reaction:

Limited or no function of the park lock until the error is corrected, indicating a critical issue with the solenoid valve circuit.

Recommendations:

Inspect Solenoid Valve Circuit:

• Check the circuit for any short circuits to supply leads.
• Repair any identified issues in the circuit.

Test Solenoid Valve:

• Measure the voltage output to the solenoid valve using a multimeter.
• Replace the solenoid valve if it is producing abnormally high voltage readings.

Examine Wiring and Connectors:

• Inspect all wiring and connectors associated with the park lock solenoid valve for signs of damage or corrosion.
• Repair or replace any damaged components to ensure proper electrical connections.

Ensure Proper Grounding:

• Verify that the solenoid valve circuit is properly grounded.
• Correct any grounding issues that may be causing voltage irregularities.

Note:

High voltage readings from the park lock solenoid valve can lead to severe operational problems. Regular inspection and maintenance of the solenoid valve and its circuitry are essential to prevent these issues.
