Description:

This diagnostic trouble code indicates that the ECU detected high resistance in the engine starter motor solenoid lockout relay driver circuit. High resistance in this circuit typically suggests an open circuit or poor connection, which can prevent the starter solenoid from functioning correctly.

Reaction:

The engine may experience starting issues or fail to start due to the inability of the starter solenoid to engage properly.

Recommendations:

• Inspect Wiring and Connections: Check for damaged, frayed, or loose wiring and connectors associated with the engine starter motor solenoid lockout relay driver circuit. Repair or replace as necessary.
• Test Solenoid Relay Circuit: Use diagnostic tools to test the resistance and continuity of the starter solenoid relay driver circuit. Ensure the resistance is within specifications.
• Check for Open Circuits: Inspect the circuit for any breaks or discontinuities that could cause high resistance. Repair or replace as needed.
• Verify Electrical Supply: Ensure that the electrical supply to the starter solenoid relay is stable and within specifications.
• Reset ECU and Monitor System: After resolving the issue, reset the ECU to clear the fault code and monitor the system to ensure normal operation.

Note:

Maintaining proper electrical connections and resistance in the starter solenoid relay driver circuit is crucial for reliable engine starting. Regular inspections and timely maintenance can help prevent resistance-related issues.
