Even if you don't repair your vehicle yourself, knowing the Diagnostic Trouble Code number before taking the vehicle in for repair is good knowledge to have. Once the vehicle is repaired, the Diagnostic Trouble Code(s) can be erased and the Check Engine light turned off using this scan tool.

In areas that require a smog test, an illuminated Check Engine light fails the emission test, even if the repaired vehicle might otherwise pass inspection. This OBDII Scan Tool turns off the Check Engine light.

Another highly useful application for the scan tool is purchasing used vehicles. Used vehicles can have all sorts of expensive mechanical or electrical problems. Since our scanner is a portable device, the buyer can connect the scan tool to the vehicle and in a few seconds determine if the vehicle has detected a problem. Remember, not all Diagnostic Trouble Codes illuminate the Check Engine light and a scan tool is the only way to obtain the information.

This reader supports all four OBDII protocols:

  • SAE J1850 PWM
  • SAE J1850 VPW
  • ISO 9141-2
  • ISO 14230 (KWP2000)
  • Attention! – If your vehicles is 2003 or newer, it may require a CAN compatible reader.


Controller Area Network (or CAN) is the newest automotive communication protocol. CAN Protocol is around 50 times the speed of the older protocols. CAN was used in some cars starting in 2003, and is said to be the only protocol that will be used after 2007.

Does My Car Have OBDII?

All cars and light trucks built and sold in the United States after January 1, 1996 were required to be OBDII equipped. In general, this means all 1996 model year cars and light trucks are compliant, even if built in late 1995.

Two factors will show if your vehicle is definitely OBDII equipped:

  1. There will be an OBDII connector located under or around the dashboard, and
  2. There will be a note on a sticker or nameplate under the hood: "OBDII compliant".

Where is the connector located? The connector must be located within three feet of the driver and must not require any tools to be revealed. Look under the dash and behind ashtrays.

The Three Flavors of OBDII

While the parameters, or readings, required by OBDII regulations are uniform, the auto manufacturers had some latitude in the communications protocol they used to transmit those readings to scanners. Naturally, each felt they had the one true way, so we have three different OBDII communications protocols in use.

What Communications Protocol does my vehicle use?

As a rule of thumb, GM cars and light trucks use SAE J1850 VPW (Variable Pulse Width Modulation). Chrysler products and all European and most Asian imports use ISO 9141 circuitry. Fords use SAE J1850 PWM (Pulse Width Modulation) communication patterns.
There are some variations among captive imports such as the Cadillac Catera, a German Opel derivative, which uses the European ISO 9141 protocol.

On 1996 and later vehicles, you can tell which protocol is used by examining the OBDII connector:
J1850 VPW — The connector should have metallic contacts in pins 2, 4, 5, and 16, but not 10.
ISO 9141–2 — The connector should have metallic contacts in pins 4, 5, 7, 15, and 16.
J1850 PWM — The connector should have metallic contacts in pins 2, 4, 5, 10, and 16.
