• Inspect the air suspension system wiring harness for any signs of damage, such as fraying or corrosion.
• Check the left rear air spring shock solenoid for proper operation and ensure it is not stuck open or closed.
• Test the voltage at the solenoid connector to confirm there is no short circuit to battery voltage.
• Examine all related fuses and relays in the air suspension system for continuity and proper function.
• Use a scan tool to clear the code and perform a road test to see if it returns, indicating an intermittent issue.
• If necessary, replace any damaged components or repair faulty wiring connections found during inspection.
