PICO CAN TEST BOX
The CAN Test Box is a diagnostic tool which connects to a vehicle᾿s OBDII connector and lets you easily diagnose electrical faults.
The CAN Test Box instantly checks power and ground circuits to identify communication link protocols.
Connect an oscilloscope for signal capture and collection of signal waveform data
How it works
The CAN Test Box uses numbered backlit LEDs which illuminate when signal data is present on the corresponding pin of the DLC. Pulsing LEDs indicate signals being pulled high/low.
The CAN Test Box gives you easy access to the 16 pins of the diagnostic connector that is fitted to all modern
vehicles. Depending on the configuration of the vehicle,this may allow you to check power, ground and CAN
Bus signal quality. With the test leads supplied you can connect your PicoScope automotive scope, or any other suitable scope, to the CAN Test Box to monitorany signals present, such as the CAN High and Low signals.

The LEDs indicate the following signals:
The CAN Test Box includes a 2.5 metre (8.2 feet) cable so that you can work in a convenient location away from the diagnostic connector, and an additional pass-through connector so that you can hook up your scan tool at the same time as your scope. The box is powered by the diagnostic connector, so no batteries or mains adaptor are needed.
The LEDs indicate the following signals:
- LED 1/9 - 485A/485B (Manufacturer’s proprietary information)
- LED 2/10 - Bus+ Line J1850/Bus- Line J1850
- LED 3/8/12/13 - future upgrade
- LED 4 - Chassis GND (GROUND)
- LED 5 - Signal GND (SIGNAL)
- LED 6/14 - CAN High of SAE J2284/CAN Low of SAE J2284
- LED 7/15 K Line of ISO9141-2 and keyword 2000485A/L Line of ISO9141-2 and keyword 2000
- LED 11 - Clock
- LED 16 Batt+ (Voltage supply)
