Understanding your car’s health has never been easier thanks to OBD-II technology. For car enthusiasts and everyday drivers alike, the ability to diagnose issues quickly and efficiently is invaluable. Enter the Autotap Obd2 Streamer, a powerful tool designed to bring professional-level diagnostics to your fingertips. This guide will walk you through setting up and using the AutoTap OBD2 Streamer, highlighting its user-friendly approach and practical application in real-world scenarios.
Connecting your AutoTap OBD2 Streamer is a straightforward process. The hardware itself is clearly labeled, distinguishing the “Vehicle” end from the “Computer” connection. Start by attaching the OBD II cable to the “Vehicle” port on the AutoTap scanner and the serial cable to the “Computer” port. Next, connect the other end of the serial cable to the DB9 serial port on your laptop.

It’s worth noting that modern laptops may not always feature a DB9 serial port. Recognizing this, AutoTap offers USB adapters to ensure compatibility, and serial extension cables are also available for added flexibility. You can find these and other accessories on the AutoTap accessory products page.
The final hardware connection involves plugging the OBD II cable into your vehicle’s DLC (Diagnostic Link Connector). This connector is typically located under the dashboard on the driver’s side. Once connected, a red LED indicator on the AutoTap OBD2 hardware should illuminate, confirming that it’s receiving power from the vehicle.

To illustrate the practical benefits of the AutoTap OBD2 Streamer, let’s consider a common scenario: the dreaded “Service Engine Soon” light. Imagine this happening to your vehicle – suddenly, warning lights appear, leaving you wondering about the cause and potential severity. Without a diagnostic tool, you’re often left guessing or relying solely on a mechanic’s diagnosis.
However, with the AutoTap OBD2 Streamer, you can quickly investigate the issue yourself. Let’s take a look at a real-life example involving a 2001 Oldsmobile Alero. The owner experienced a “Service Engine Soon” light and a “Trac Off” light illuminating after a battery replacement at a dealership. While professional scan tools are available, older vehicle updates can sometimes lag, rendering them less effective on certain models. In this case, the AutoTap system proved to be current and readily identified the problem.

Connecting the AutoTap OBD2 Streamer to the Alero’s DLC connector was the first step. With the hardware connected, launching the AutoTap software on the laptop is just a few clicks away.

After clicking the AutoTap icon and then the “Connect to a Vehicle” button within the software, the system initializes communication. During this process, a potential conflict was identified: the laptop also used a Palm handheld device that utilized the same serial port for “HotSync”. The Palm HotSync manager, running in the background, was preventing the AutoTap system from accessing the necessary port.

The solution was simple: exiting the Palm HotSync manager freed up the serial port for the AutoTap OBD2 Streamer. This highlights an important point – ensure that the communication port required by AutoTap is available and not being used by other applications.
Once the port conflict was resolved, the AutoTap system quickly established a connection with the vehicle. Navigating to the DTC (Diagnostic Trouble Code) section of the software revealed the stored codes responsible for the “Service Engine Soon” light.

The diagnostic result was a DTC indicating an issue with the Intake Air Temperature (IAT) sensor circuit – specifically, a “IAT circuit high” code, suggesting an open circuit. A quick visual inspection under the hood confirmed the problem: the IAT sensor was unplugged.

Reconnecting the sensor harness resolved the issue, demonstrating the AutoTap OBD2 Streamer’s ability to pinpoint problems quickly and accurately. Beyond basic DTC reading, the AutoTap software offers advanced features. Within the DTC window, an “Advanced” function button provides access to customizable settings. Users can enable or disable DTC checking and MIL (Malfunction Indicator Lamp) status updates, and even set the interval for automatic checks. These options allow for a tailored diagnostic experience, providing real-time monitoring and customizable reporting.
