The "Canfinder" is probably one of the most valuable testing tools in your towbar technicians workshop! The Canfinder is a useful gadget giving you an electrical and electronics testing tool all in one!


Finds pulsed live feeds without breaking the wire insulation:-

  • Pulsed feeds
  • CANbus signals both CAN high and CAN low

With the visual LED or sounder readout on the CANfinder, the CANbus network can be easily identified. A sounder indicates that there is some data activity on the bus and with some practice you can hear if the data-flow sounds healthy. The red or green LED light identifies if the wire is CAN-Hi or CAN-Lo.

CANfinder Towbar Technicains Testing Tool


One of the most useful benefits of the CANfinder is that you can see that the data-flow stops when the vehicle is turned off and goes into shut down mode. This confirms that you know the vehicle battery wont discharge after the towbar installation.

Modern vehicles are packed with a multitude of digital electronics. Use the CANfinder to locate and track these signals. If you have to work under the dashboard or in places with poor lighting there is an integral light mounted on the front of the CANfinder to help you identify the cables.

CANfinder can also be used to test pulses on different types of lights. You can use it to identify 'Pulse Width Modulation' lights which have double function such as the brake light& tail light.

Additional Uses

Additional uses include, for example, finding problems of interference from a windscreen wiper motor or a bad Xenon lamp. It is also possible to test the ignition. The Lambda Sensor can be checked to see if gives a regulation signal or not.
