Practical CAN Bus Diagnostics

Build Confidence in CAN Bus Diagnostics

CAN Bus faults can quickly become confusing. Network diagrams, resistance measurements, CAN High and CAN Low waveforms, multiple modules and communication faults can make it difficult to know where to test next.

Over four weeks, Darren will help you build a logical CAN Bus diagnostic process that you can take back and use in the workshop.

By the end of the Master Class, you'll have a better understanding of how CAN Bus works and a logical process for diagnosing network faults with confidence.

Understand how CAN networks operate

Carry out resistance and voltage tests

Set up an oscilloscope for CAN testing

Analyse CAN High and CAN Low waveforms

Diagnose communication faults logically

Your Training Roadmap

From CAN Bus Basics to Advanced Diagnostics

Four weeks of structured training designed to build your knowledge step by step and turn it into a practical diagnostic process.

WEEK01

CAN Bus Fundamentals

Understand how CAN Bus communication works, network structure, CAN High and CAN Low, termination and perform quick diagnostic test to confirm network operation.

WEEK02

Oscilloscope Diagnostics

Learn how to set up the oscilloscope for different fault scenarios, identify what good measurements should look like and how to recognise when something isn't right. Use Math Channels to get deeper insights on network health.

WEEK03

CAN Bus Fault Diagnosis

Work through CAN Bus faults and learn how to follow a logical diagnostic process instead of guessing or replacing parts unnecessarily. Analyse oscilloscope waveforms for various different fault types.

WEEK04

CAN Bus Analysis and Advanced Techniques

Use CAN Bus analysis and serial decoding to identify messages on the CAN bus network and use various software to help reverse engineer CAN messages for diagnostic scenarios.

Train Live With Darren

Learn directly with Darren over four weeks as he breaks CAN Bus diagnostics down into practical testing methods and a logical diagnostic process you can use in the workshop.

Real Workshop Experience. Practical Training.

Darren started as a BMW apprentice and spent 10 years on the workshop floor dealing with real diagnostic challenges. He later moved into technical training and led the Audi UK Master Technician programme, working with hundreds of experienced technicians, before joining JLR Train-the-Trainer team and leading the training development creation.

That combination of workshop and training experience shaped Darren's approach to teaching diagnostics: take complex subjects, make them easier to understand, and give technicians a logical process they can confidently apply to real faults.

Live Training

Being able to ask questions in real-time during the live sessions is invaluable. Darren doesn't just teach theory—he works through actual vehicle scenarios with us. The interactive format means I can apply what I learn directly to my workshop the next day.

Confidence Boost

Before Mechanic Mindset, I was outsourcing any electrical work I couldn't figure out. Now I tackle CAN Bus diagnostics with confidence. Darren has a gift for making complex topics accessible. My diagnostic accuracy has improved dramatically.

Frequently Asked Questions

Questions About the CAN Bus Master Class?

Who is the CAN Bus Master Class for?

The programme progresses from fundamentals through to advanced CAN Bus diagnostics and is designed for automotive technicians wanting to improve their CAN Bus knowledge and diagnostic process.

I'm relatively new to CAN Bus. Is this suitable for me?

The Master Class starts with the fundamentals before progressing into more advanced testing and diagnostics, making it accessible for those newer to CAN Bus technology.

Why is the Master Class limited to 300 participants?

This is intended to be interactive training with live Q&A, direct interaction with Darren and a private group, rather than a large one-way webinar. We have a global audience so the clinics will be delivered at different time to allow everyone to chance to join live.

What if I can't attend one of the live sessions?

Every session will be recorded and participants receive lifetime access to all recordings.

What equipment will I need?

Equipment is not mandatory to join, however the following tolls will enhance the learning experience:

- Multimeter

- Scan tool

- Oscilloscope

- Computer with Windows OS

What time are the live sessions?

Live Training will be delivered at weekends around 7pm UK time. We will then host additional 'CAN Bus Clinics' so you can join and ask questions, review activities or explore CAN bus case studies and testing techniques. We will record all sessions, and grant lifetime access to recordings.

How long is each session?

Training Sessions will last between 2-3 hours with time for Q&A.

CAN Bus Clinic will last from 1-2 hours depending on engagement.

Is the CAN Bus Diagnostics Book included?

Yes, the CAN Bus Diagnostic book is included with the Master Class and can be used to follow along with the training and complete activities.

Where do you ship the book?

We ship globally. Occasionally it's difficult to ship to remote locations, however we make best efforts to get the items to you.

When will I receive my book?

We will send you the instruction to order your and tool. Shipping can take between 1-2 weeks depending on your location and local customs process.

How do I access the private chat group?

We will have a private community for all Master Class attendees. You can access it from your online Mechanic Mindset account by signing in to mechanicmindset.com, or by downloading the Mechanic Mindset mobile app.

How long will I have access to the recordings?

We have offered lifetime access to the program after it ends. As long as Mechanic Mindset is operational, you will have access to the recordings via your Mechanic Mindset account. If anything should happen, we will make arrangements to ensure access is continued.

Is the Master Class included with Diagnostic Coach membership?

The Master Class is separate to the Diagnostic Coach program.
