5.2 Connecting the GT105 ECU AD Break Out Box
The GT105 can be used for various purposes, including OBD2 short-circuiting, ECU diagnosis, and providing external power. It connects to the vehicle's OBD2 port or directly to the ECU via its breakout cables.
- For OBD2 short-circuiting or diagnosis, connect the GT105 to the vehicle's OBD2 port.
- For direct ECU connection, use the provided breakout cables to connect to the ECU's pins, ensuring correct pin assignments for power, ground, and communication lines.
- The GT105 can draw power from the vehicle's battery for outdoor maintenance by connecting the appropriate power cables.
6. Operating Instructions
6.1 Using the GODIAG GT107 Gear-Box Data Adapter
The GT107 features an analog ignition switch with two modes:
- Auto Mode: The switch is not pressed.
- Manual Mode: The switch is pressed down.
Important: When performing data reading or writing operations, ensure you select the corresponding mode (Auto or Manual) within your diagnostic or programming software (e.g., PCMFlash, PCMTuner, Kessv2) to match the GT107's switch setting. Mismatched modes can lead to communication errors or failed operations.
6.2 Interpreting GT105 Communication Indicators
The GT105 is equipped with LED indicators for various communication protocols. These indicators help in verifying communication status:
- PWM+ (PIN2): Indicates Pulse Width Modulation communication activity.
- CANH (PIN6): Indicates CAN High communication activity.
- CANL (PIN14): Indicates CAN Low communication activity.
- K-line (PIN7): Indicates K-line communication activity.
When data communication occurs on a specific protocol, the corresponding indicator LED will flash. This allows you to quickly determine if the diagnostic or programming device is successfully communicating with the ECU.
