CAN Test Box

can test box

 

Continuing with our mission to make vehicle diagnostics easier and faster…the new 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 lab scope to the CAN Test Box to monitor signals such as the CAN High and Low. More.....

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 monitor any signals present, such as the CAN High and Low signals.

The CAN Test Box connects to a vehicle᾿s OBDII / EOBD connector and lets you easily diagnose electrical faults.

Instantly check power and ground circuits
Identify communication link protocols
Connect an oscilloscope for signal capture and collection of signal waveform data
Compatible with both 12V and 24V vehicles

How does it work?


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 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)


The CAN Test Box allows you to connect your PicoScope oscilloscope or any other compatible scope, enabling you to monitor any signals present such as the CAN High and Low signals. The CAN Test Box terminal pin ports are compatible with standard 4 mm jacks.

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.

Typical Uses


The connection of the Can Test Box to the 16 pin vehicle diagnostic connector provides a non-intrusive test point for all associated circuits, whilst LED’s will illuminate to indicate the status of the 16 pins. The 4mm banana sockets enable simple connection of PicoScope for circuit analysis, “jumper wires” for flash code interrogation, and on board “memory save” devices (During battery disconnection) With the pass-through connector and 2.5 meter cable, the Can Test Box can be used in series with your scan tool and remote from the 16 pin connector allowing for simultaneous scan tool and scope tests. (See below)
 

  • Power and ground test for communication errors
  • CAN HI CAN LOW activity (depending on manufacturer)
  • Convenient “jumper wire” access point for flash code access or initialisation procedures
  • Convenient point for “memory save” device connection
  • Remote access to concealed 16 pin connectors via 2.5 meter cable
  • Pass-through feature does not restrict scan tool access when connected
