Reset Indicator Lights Cost Estimate

What parts do I need to reset indicator lights and how much do those parts cost?

There are no parts involved in an indicator light reset. Your mechanic will utilize your vehicle's controls, an OBD-II scanner, and your owner's manual to perform the reset. Here's what's needed for the reset process:

1. Vehicle’s owner’s manual:Your mechanic will utilize the vehicle's onboard controls to navigate its computer system, which governs the indicator lights. The steps for accessing and resetting these lights are usually outlined in your vehicle's owner's manual, which is typically provided at no extra cost when you purchase the vehicle.
2. OBD-II scanner: An OBD-II scanner is a diagnostic tool capable of reading and clearing diagnostic trouble codes (DTCs), which trigger your indicator lights. Your mechanic will connect the OBD-II scanner to your vehicle’s OBD port and use it to clear any existing trouble codes, thereby resetting your indicator lights.
3. The battery:Resetting some indicator lights can be achieved by disconnecting your car’s battery for a few minutes. However, this method is usually avoided because it resets not only your indicator lights but also your car radio and other vehicle settings. Additionally, it may have an impact on certain parts of your car.

Resetting your indicator lights will clear the dashboard icons, but it won't fix the underlying issue that triggered the lights to come on initially. If the indicator light reappears after the reset, there's likely an ongoing problem that requires diagnosis and repair.

How will a mechanic reset my indicator lights?

Here are the different methods your mechanic might use to reset your indicator lights:

1. OBD-II scanner: The simplest method for resetting indicator lights involves using an OBD-II scanner, also referred to as an onboard diagnostic tool. Your mechanic will find the OBD-II port beneath the dashboard to access the car’s onboard computer, such as the engine control unit (ECU) or powertrain control module (PCM). Using the scan tool, they can identify the trouble codes linked to the indicator lights. After addressing the underlying issues and completing any required repairs, your mechanic will clear the trouble codes, effectively resetting and turning off the indicator lights.
2. Vehicle controls:Your mechanic can access the onboard computer through the infotainment system or instrument cluster, following the instructions outlined in your vehicle’s owner’s manual. Using the infotainment system or instrument cluster, they will navigate to the diagnostic information and perform the required steps to reset the relevant indicator lights.
3. Disconnect the battery: Depending on the vehicle and the type of indicator lights, your mechanic may disconnect the car battery for a few minutes to reset the indicator lights. This action can sometimes clear the ECU or PCM's memory, erasing trouble codes that trigger the indicator lights.
4. Suggestions from the vehicle owner’s manual:Some indicator lights can be turned off using specific procedures outlined in the vehicle's owner's manual. Your mechanic will follow the recommended steps provided in the manual to reset the lights.

What happens if I don’t reset indicator lights?

What are indicator lights?

Indicator lights, also referred to as dashboard warning lights, are small symbols that light up on a vehicle’s dashboard instrument cluster when there’s a problem with one or more vehicle components. These symbols inform the driver about issues or changes in the vehicle’s system, such as engine or emissions problems, low oil pressure, battery issues, or tire pressure concerns.

Here are some common indicator lights you may see on your instrument panel: /p>

• Check engine light
• Coolant temperature light
• Tire pressure monitoring system (TPMS) light
