Connection guidance

Connection for diagnostic work will vary dependent on the application.

Please select guidance for your specific application from the navigation menu.

Circuit testing

Technicians should wherever possible gain access to the test circuit without damage to seals and insulation. If this is not possible then make sure appropriate repairs are completed.

General connection advice

PicoScope offers a range of options within the test kits.

Dependent on difficulty of access, choose from:

  1. Breakout leads.
  2. Back-pinning probes.

Testing sensors and actuators (to include relevant circuit/connectors):

  • When testing a sensor, it is desirable to gain access at the control module.
  • When testing an actuator, it is desirable to gain access at the actuator.

There are so many questions from Pico users, pico should make a video of every test of every sensor.  Better yet make a complete simulator that faults can be created .  For instance a simulation of a vehicle with every possible sensor where faults can be triggered and wave forms viewed.Or a link to every sensor on the market with their values. Or a cloud where everyone can upload their videos, or links to there video with a very good search engine.
