Capable of connecting between the Diagnostic Link Connector and a scan tool, this CAN test box monitors OBDII data lines and protocol communication. It tracks system voltage through a digital display with integrated high and low alarms to identify faults in power and ground circuits. Flashing LEDs at the pin-out display signal detection and ECU activity while providing access points for multimeter or oscilloscope leads for detailed signal analysis.
