Is your vehicle an OBD2 fit

The THINKCAR 641 is a wireless scanner for 1996 and newer OBD2 vehicles, covering 118 or more brands. It supports many 12V models, from compact cars to light-duty trucks, so we recommend checking your exact year and model against the coverage list before you buy.

It also supports CAN FD and FCA AutoAuth, though AutoAuth applies only to Renault, Nissan and Chrysler vehicles and requires a separate account. If you drive one of those, you will need to set that up before you can rely on AutoAuth features.

What it will not do

This scanner reads and clears codes from engine, transmission, ABS and SRS systems, but it is not a repair tool. It does not fix the underlying fault, and a discount on the scanner does not make a vehicle safe to drive or diagnose a problem on its own.

The 10 reset functions cover common service tasks such as ABS bleeding and oil service reset, along with others like battery matching and DPF regeneration. Those functions are supported, but they do not replace proper service procedures or mechanical work.

What it will not do

We'd skip it if you need a tool that performs repairs or guarantees a repair outcome.

Difference
$63.63 (32 percent)

At $134.98, the THINKCAR 641 is $63.63 below its typical price over the last 90 days of $198.61. That 32 percent difference applies to the current offer.

This is also the all-time low price for the scanner. Our advice is to consider it at this price if the features match your needs, since it rarely drops below this point.

Power and connection checks before you buy

The scanner uses a Bluetooth 5.0 VCI dongle that plugs into your vehicle's OBD2 port and pairs with the handheld unit wirelessly, so you will need a working OBD2 port within reach. No Wi-Fi is required during diagnosis, and the core scans run independently without a phone.

Updates come through Wi-Fi, so you will need a Wi-Fi connection at some point to keep vehicle coverage current. The dongle draws power from the OBD2 port, but you should confirm that your vehicle provides power to that port when the ignition is on.

Since the scanner works on 12V systems, check that your vehicle is a 12V OBD2 model before ordering. For any specific vehicle, confirm compatibility through the brand's coverage list or customer support.

Who should choose this scanner

This scanner suits weekend DIYers, used-car buyers and budget-conscious owners who want to read engine, transmission, ABS and airbag codes and handle common reset tasks without a shop visit. It is also a good fit if you maintain several vehicles and need a wireless tool that works without a phone.

If you only need engine codes or your vehicle falls outside the supported 1996 and newer OBD2 range, a simpler code reader may be enough. For those who need the four-system coverage and the ten resets, this is a solid pick at this price.

Before you buy, confirm your vehicle's compatibility and that your OBD2 port supplies power. That final check makes sure the scanner connects and runs the way you expect.
