What Is a Car Code Reader?

Car code readers ⁠— most commonly known as OBD2 or OBDII scanners ⁠— are unique tools that help drivers diagnose their car issues. Once your scan tool is attached to your vehicle’s OBD (on-board diagnostics) port, it can pull a five-character trouble code that can be translated into where the vehicle issue is located, whether it’s a manufacturer-specific or universal issue, and more. Take these common trouble codes, for example:

  • Codes B1555 to B1558 indicate issues with the ignition start circuit
  • Codes P0300 to P0312 indicate engine misfires caused by multiple cylinders or a specific cylinder
  • Codes U1098 and U1099 indicate invalid or missing data for your vehicle speed control

OBD2 scanners cannot tell you exactly how to fix your vehicle, but by providing trouble codes, they help you narrow in on a single corrupted area, allowing you to save time and money by fixing it yourself or diagnosing your issue ahead of your trip to the mechanic.

As we’ve noted in a previous article, only vehicle models manufactured in 1996 or later have OBDII ports that can connect to OBD2 scanners. For older vehicle models, you’ll likely have to shop for an OBD-I scanner, which are not universal to all car makes.

Why Do I Need a Car Code Reader?

When driving for a rideshare app is one of your primary sources of income, you’ll be putting plenty of miles on your car. The more you use your vehicle, the faster the wear can affect your engine and other parts of your vehicle. Having your OBDII car code reader in hand keeps you prepared for the inevitable check engine light, even if it turns on while you’re on the road.

In addition, OBD2 scanners can save you a significant amount of money. By helping you diagnose the issue, you can take a trip to your local auto shop and repair it yourself. This will save you a costly trip to the mechanic, which is especially helpful if a foreign object lodged in the trouble area is the only issue. If you’re not as adept at vehicle maintenance, knowing your fault code will at least prevent your mechanic from charging you for unnecessary repairs in other parts of your car.

This makes it incredibly easy for you to avoid a trip to the mechanic.

One of our favorite features of this car code reader is the availability of battery health and voltage testing, straight from the comfort of your vehicle.

Frequently Asked Questions

When you’re working as an independent contractor — as all Uber and Lyft drivers do — taking time off work can decrease your weekly earnings without compensation. An OBD2 scanner is the perfect tool to help you fix your vehicle in a pinch. Here are a few frequently asked questions to help you decide which one to buy:

1. Are OBD2 scanners required by any rideshare company?

No, rideshare drivers are not required to have OBD2 scanners and are not reimbursed for their scan tool purchases. The scanner is more of a proactive purchase to help you maintain your vehicle.

2. Can I deduct my OBD2 scan tool purchase from my taxes?

When tax season comes around, make sure you have your OBD2 scanner purchase logged in your list of tax deductible receipts. This tool is considered a deductible business expense for the vast majority rideshare drivers. We recommend consulting your accountant when you file your taxes to ensure your purchase qualifies.

3. I can’t afford a scan tool right now. What can I do when my check engine light comes on?

While we highly recommend rideshare drivers have scan tools for emergencies, we do understand a tight budget. When your check engine light turns on, you can head to one of your local auto parts store and borrow a car code reader there. National stores like O’Reilly Auto Parts and NAPA Auto Parts typically have at least one on hand, although it wouldn’t hurt to call ahead to ensure that you’re not wasting time driving around town without earning a buck.
