After Servicing Full Car: Should the Spanner Sign Come Back On?

After servicing your car, the last thing you want to see is the dreaded spanner light illuminating your dashboard. It can be confusing and concerning, raising questions about the effectiveness of the service you just paid for. This article addresses the common query “after servicing full car should spanner sign come back on?” and explores various reasons why this might happen, along with helpful troubleshooting tips.

Understanding the Spanner Light

The spanner light, sometimes referred to as the wrench light, is a general service reminder. Unlike the check engine light, which indicates a potential problem with the engine’s emissions system, the spanner light is tied to your car’s service schedule. It’s designed to remind you when routine maintenance, like an oil change or filter replacement, is due.

Why Does the Spanner Light Come On After Service?

If the spanner light reappears after a full service, it could be due to a few reasons:

• Service Reminder Reset: The most common reason is that the mechanic simply forgot to reset the service reminder. This is a simple procedure, often involving a specific sequence of button presses or using a diagnostic tool.

• Incorrect Reset Procedure: Even if the mechanic attempted to reset the reminder, they might have used the wrong procedure. Different makes and models have unique reset methods, and using an incorrect one can be ineffective.

• Underlying Issue: In some cases, the spanner light might reappear due to a genuine problem. This is less likely immediately after a full service but possible if an existing issue wasn’t addressed or a new problem has developed.

• Sensor Malfunction: A faulty sensor could trigger the spanner light even if everything is functioning correctly. This requires further diagnosis to identify the specific sensor causing the issue.

Troubleshooting the Spanner Light

If the spanner light comes on after a service, here’s what you can do:

1. Check Your Owner’s Manual: Your manual will detail the specific procedure for resetting the service reminder for your car model. Attempt this reset yourself before contacting the mechanic.

2. Contact the Service Center: If the manual reset doesn’t work, contact the service center that performed the maintenance. They should be able to reset the light correctly or diagnose any underlying problems.

3. Use an OBD-II Scanner: An OBD-II scanner can read diagnostic trouble codes (DTCs) stored in your car’s computer. This can help pinpoint the cause of the spanner light if it’s related to a sensor malfunction or other issue.

Preventing Future Spanner Light Issues

To avoid future issues with the spanner light:

• Ensure Proper Service: Choose a reputable service center that specializes in your car make and model. This ensures they’re familiar with the correct service procedures and reset methods.

• Maintain Service Records: Keep detailed records of all maintenance performed on your vehicle, including the date, type of service, and mileage. This can help diagnose future problems and ensure the service reminder is reset correctly.

• Regular Inspections: Perform regular checks of your car’s fluids, tire pressure, and lights. This can help identify potential problems early on and prevent more serious issues.
