The CAN Test Box (CTB) is a diagnostic device that connects to the OBDII connector of the car or truck, allowing you to quickly and easily detect electrical faults. With the Breakout Box, direct control of the ground and power supply in the OBDII connector is possible. In addition, the device identifies the communication protocol and allows you to measure data signals using a scope. DiagnosES from Winsum is happy to inform you about the operation of this device.

- Pin 2 – J1850 Bus+
- Pin 4 – Chassis Ground
- Pin 5 – Signal Ground
- Pin 6 – CAN High (J-2284)
- Pin 7 – ISO 9141-2 K Line
- Pin 10 – J1850 Bus
- Pin 14 – CAN LOW (J-2284)
- Pin 15 – ISO 9141-2 L Line
- Pin 16 – Battery voltage
The applications of the CAN Test Box
