Description:

This diagnostic trouble code indicates that the ECU detected low resistance in the engine starter motor solenoid lockout relay driver circuit. Low resistance in this circuit typically suggests a short to ground, 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 Short Circuits: Inspect the circuit for any points where wires may be touching ground, causing a short circuit. Repair or insulate 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.
