Experiencing car trouble and seeing those dreaded warning lights illuminate on your dashboard? A check engine light or ABS light can signal a range of issues, from minor to major. Quickly diagnosing the problem is crucial to prevent further damage and ensure your safety on the road. That’s where a reliable check engine and ABS scan tool comes in. This article discusses how diagnostic trouble codes (DTCs), specifically relating to the Anti-lock Braking System (ABS) and Powertrain Control Module (PCM), can help pinpoint the issue and guide you toward a solution. Finding a “Check Engine And Abs Scan Tool Near Me” is the first step in addressing these concerns.
Understanding Diagnostic Trouble Codes (DTCs)
Your car’s onboard computer system constantly monitors various components and sensors. When a problem is detected, it generates a specific DTC stored in the system’s memory. These codes, often starting with “U” for communication network issues, “P” for powertrain, “B” for body, and “C” for chassis, provide valuable clues about the nature of the malfunction.
For instance, the ABS module might generate DTCs like U0401:68 and U0415:00, while the PCM might generate P0300. These codes, referenced in the 2017 Ford Edge Workshop Manual, indicate communication errors or specific component failures.

Importance of Networked Communication
Modern vehicles rely on a complex network of interconnected modules that communicate with each other. The Instrument Panel Cluster (IPC) relies on these messages to display accurate information. When a message is missing, the IPC follows a predefined strategy:
- Short Interruption: If a message is missing for a short period (e.g., less than 5 seconds), the display remains in its last known state.
- Prolonged Interruption: If the message is missing for an extended period, the IPC sets a U-code DTC and defaults to a predefined action (e.g., turning a warning light on or off, setting a gauge to a rest position).
A common example is DTC U0121, which indicates lost communication with the ABS module. This code, triggered by missing data messages from the ABS module to the PCM, can point to issues within the communication network, the ABS module itself, the Body Control Module (BCM), or even the PCM.
Using a Check Engine and ABS Scan Tool
A check engine and ABS scan tool allows you to access and interpret these DTCs. By connecting the tool to your car’s OBD-II port, you can retrieve the stored codes and gain insights into the underlying problem. Many auto parts stores offer code reading services, but owning a scan tool empowers you to diagnose problems yourself.
When searching for a “check engine and ABS scan tool near me,” consider factors like functionality, compatibility with your vehicle’s make and model, ease of use, and price. Options range from basic code readers to advanced scan tools with live data streaming and bi-directional control capabilities.
Diagnosing and Resolving Issues
Once you have the DTCs, consult your vehicle’s repair manual or online resources for detailed troubleshooting procedures. The workshop manual often provides step-by-step instructions, known as Pinpoint Tests, to guide you through the diagnostic process.
Remember, diagnosing car problems requires a systematic approach. Start by verifying the customer concern, checking the communication network, performing self-tests on relevant modules, and reviewing DTCs from all modules.
Finding a “check engine and ABS scan tool near me” is the first step in getting to the root of your car troubles. Accurate diagnosis, guided by DTCs and a reliable scan tool, can save you time and money on repairs.
