CAN Bus Troubleshooting Training
You’re staring at a CAN network that won’t communicate. The machine is down, the customer is waiting, and you’re swapping ECUs hoping something works. Sound familiar?
This course replaces trial-and-error with a systematic diagnostic method. You’ll learn exactly where to probe, what to measure, and how to isolate faults — whether it’s a wiring issue, a bad node, or a protocol-level problem. No more guessing.
Stop guessing. Diagnose CAN faults in minutes, not hours.
After this course, you will:
- Isolate CAN faults to specific nodes or wiring segments
- Measure CAN_H, CAN_L, and differential voltages correctly
- Interpret system diagrams to trace signal paths
- Determine if a fault is wiring, termination, or ECU-related
The Course
Three modules. Theory, tools, then real-world application.
Module 1: CAN Fundamentals
- How CAN networks communicate
- Physical layer: CAN_H, CAN_L, differential signaling
- Topology, termination, and why it matters
Module 2: Diagnostic Tools & Techniques
- CAN wiring measurements with a DMM
- Reading system diagrams like a pro
- Electrical overview: what good vs. bad looks like
Module 3: Real-World Fault Isolation
- The fault isolation flowchart
- Wiring diagnostics: opens, shorts, and degraded connections
- Advanced: intermittent faults and multi-node failures
Results from real engineers
“I diagnosed an intermittent CAN fault in 20 minutes that had stumped our shop for two weeks. The systematic approach in Module 3 paid for the course ten times over.”Senior Field Engineer, Heavy Equipment Dealer
“Before this course I was swapping ECUs hoping to fix the problem. Now I know exactly where to measure and what the readings should be. Completely changed how I work.”Service Technician, Fleet Maintenance
“We enrolled our entire service team. Repair times on CAN-related issues dropped by about 40%. The ROI was immediate.”Service Manager, OEM Dealer Network
This course is for you if:
- Field technicians tired of swapping parts without understanding why
- Service engineers who want faster, more accurate diagnostics
- Fleet managers who need their team diagnosing consistently
- Anyone responsible for CAN-based equipment uptime

How long is the course?
About 8 hours of video instruction plus hands-on exercises. You have 1 year access — most technicians work through it over a few weeks, then revisit specific sections when they encounter those fault types in the field.
Will this work for my specific vehicle or equipment?
Yes. The diagnostic methodology applies to any CAN-based system: heavy equipment, trucks, passenger vehicles, marine, agricultural, or industrial machinery. The principles are universal.
Is this for beginners or experienced technicians?
Both. You need basic electrical knowledge (voltage, using a multimeter). Beginners get a systematic foundation; experienced techs fill gaps and learn faster methods they may have missed.
Can I try before I buy?
Yes. Get a free lesson here — see the teaching style and depth before you commit.
Do you offer team or fleet pricing?
Yes. Teams of 5+ get volume discounts, and we can provide completion tracking for managers. Contact us for team pricing.
Is the certificate recognized?
The Certificate of Completion is issued by CAN Bus Academy and can be added to your LinkedIn profile or HR records. It demonstrates competency in CAN bus diagnostics to employers and clients.
