For Mitsubishi 3000GT owners, understanding your car’s complex systems can feel like deciphering a secret code. These vehicles, especially the first generation models, are equipped with numerous onboard computers that manage everything from the engine to the suspension. Communicating with these systems for diagnostics used to require expensive dealer tools or complex analog methods. Fortunately, tools like the Black Stealth computer scanner emerged to bridge this gap, offering a more accessible way to understand your 3000GT’s health.
This review delves into the experience of using a 3000gt Scan Tool, specifically the Black Stealth scanner, on a ’92 Stealth TT. This tool is designed to interface with the OBD1 port of first-generation 3000GTs and similar models, drawing power from the cigarette lighter socket. Its key strength lies in its ability to communicate with a wide array of your car’s computers, including:
- ECU (Engine Control Unit): The brain of your engine, managing performance and emissions.
- ABS (Anti-lock Braking System): Ensuring safe and controlled braking.
- SRS (Supplemental Restraint System): Managing your airbag system for safety.
- ETACS (Electronic Time and Alarm Control System): Controlling convenience features like lights and alarms.
- ECS (Electronically Controlled Suspension): Adjusting suspension stiffness for optimal ride and handling.
- Transmission (Automatic Transmissions): Monitoring and controlling automatic gearbox functions.
The brilliance of a dedicated 3000GT scan tool like the Black Stealth is its ability to read error codes and monitor sensor data across these diverse systems. Beyond just reading codes, these tools can often perform tests on various components controlled by these computers, offering a deeper level of diagnostic capability.
In a practical scenario, using the Black Stealth scan tool to diagnose ABS and SRS light issues revealed valuable insights. To initiate communication, the ignition key needs to be in the ACC or Run position to activate the car’s systems. Navigating the tool’s interface requires a bit of familiarization. Specifically, after selecting a system like the engine ECU, it’s necessary to use the up or down buttons to access the menu options, including the crucial “scan system for errors” function.
Initial attempts might yield a flurry of error codes, some of which could be historical. Persistence and careful menu navigation, possibly with guidance, are key to accurate diagnosis. In this case, the scan tool pinpointed:
-
ABS – Bad Motor Relay: Located within the front wheel splash guard, this relay is a prime suspect for ABS issues. Replacement is a logical next step to further isolate potential problems.
-
SRS – G Sensor TRBL2 (Code 12): Indicating an open circuit in a front SRS sensor. While some SRS errors can be reset, this code suggests a more persistent issue requiring further investigation and potential sensor replacement.
While previous ECU and ECS errors had been resolved separately, the 3000GT scan tool proved its value in diagnosing and clarifying the ABS and SRS issues. For 3000GT owners tackling electrical or system-related problems, investing in a compatible scan tool is a significant step towards effective troubleshooting and repair.
Note: The Black Stealth scan tool discussed in the original article has been discontinued. However, a replacement product is available for 3000GT owners seeking similar diagnostic capabilities. You can find more information on the updated version here: Stand-Alone Scan Tool for 3000GT.
