There are two
CAN Bus training from
Veejer Enterprises, Inc.
Option 1 is reading a book
2 is "hands-on" training
Read about both options below.
1: A book, the title:
Things They Don't Tell You About
CAN Bus Troubleshooting"
A 49 page training program discusses
how the CAN Bus system operates and explains several ways to
test the live CAN Bus signal on the vehicle. We demonstrate three
ways to determine if CAN Bus data is flowing without using a
lab scope. We explain the unique and dedicated CAN Bus transceiver
circuit inside every control unit (Node) connected to the CAN
Bus network. We show you how to test the transceiver circuit in an on-board
control unit with common VOMs and DMMs to determine if it has
likely failed to help the technician decide a new control unit
is definitely needed. The training program concludes with a simple
step-by-step CAN Bus troubleshooting procedure.
This training program contains
20 diagrams of schematics and illustrated electrical test procedures
with 43 color photographs showing the step-by-step test procedures
and good readings obtained. Any tech can learn these simple electrical
test procedures to restore CAN Bus operation and repair common problems.
This is the first time some of this information has been made
available to service technicians.
You have two ways to purchase a copy of the CAN Bus book - either in PDF format or a printed book.

2: "Hands-On" Training
CAN Bus "Hands-On" Troubleshooting
Training Program, H-200
Technicians repairing CAN Bus
failures must have specific troubleshooting skills to repair
CAN Bus wiring network problems as well as troubleshoot the voltage
feeds (B+) and ground circuits (B-) to any Node. The CAN Bus Trainer
Board efficiently provides this electrical troubleshooting training.
The CAN Bus Trainer, H-PCB200, is shown below connected to the
Power Board from the Starter Kit, H-111A.
are two parts to the training program included in the H-200 CAN Bus
"Hands-On" Troubleshooting Training Program.

Power Board, H-PCB01 from the Starter Kit H-111A.
One covers network wiring problems and requires the stand alone CAN Bus Trainer H-PCB200)
If network resistance measured at the DLC Pins 6 and 14 is 60
ohms, or 120 ohms, what does that indicate? What else could be
wrong with CAN Bus network wiring when 60 ohms is measured at
the DLC? This is just one of the many topics covered. Sixty ohms does not always confirm a good CAN Bus network exists. The student workbook provides troubleshooting
steps and practice troubleshooting exercises
to find the problem with "hands-on" testing using an
There are 20 common CAN Bus failures
in the 60 ohm CAN Bus network with only 3 Nodes connected to the CAN Bus. The more Nodes there are the greater the chance of a wiring failure. Many network wiring failures occur
when the network measures 60 ohms at the DLC. At other times, a 60 ohm reading will hide a network failure that kills CAN Bus operation. Learn how to identify these problems and repair them.
in the Student Workbook explains and illustrates the troubleshooting
techniques needed to identify any network wiring failure. All
network wiring faults can be trouble shot without the need to
connect to the CAN Bus Trainer to the Power Board. All you need is a H-PCB200 trainer
board, a copy of the student workbook and a digital ohmmeter.
the CAN Bus Trainer be connected to the optional Power Board and Power Supply contained in H-111A Starter Kit which is purchased separately.

After CAN Bus network wiring is repaired or proven to be fully
functional, instruction is provided in the student workbook H-WB200 for
testing Node voltage and ground circuit problems with a voltmeter (DMM).
If a DTC (Diagnostic Trouble Code) indicates a problem with a
Node, what should be checked next to ensure the Node has what
it needs to function? The CAN Bus Trainer, H-PCB200, provides
hands-on troubleshooting training for these electrical issues.
There are 24 electrical problems
relating to voltage and ground circuit problems to Nodes. To
troubleshoot these voltage and ground side problems you must
have a Power Board from H-111A to complete the live circuit.
The "live" circuit simulates power and ground circuits
connecting to Nodes and the electrical problems that can occur
(OPENs, Voltage drops and shorts-to-ground and shorts-to-voltage).
There are 4 additional advanced troubleshooting problems that
will test your newly acquired CAN Bus troubleshooting skills.
That's a total of 28 practice voltage and ground problems to
Nodes in Part Two.
Please Note: The CAN Bus Trainer Board, H-PCB200,
does not provide an active CAN Bus signal on the network. To
do so would require extensive circuitry and very high cost that
would make this training program too expensive to produce or purchase.
Besides, a technician is not responsible to go into a Node (on-board
computer) to perform internal circuit board repair. The job of
the technician is to confirm the Node has an internal problem
and stop there. He determines the Node should be replaced and have
confidence the problem will be resolved.
All of these
CAN Bus failures would be practically impossible to duplicate
on an actual vehicle due to the time required inserting problems
and gaining access to a wide range of vehicle circuits. The H-200 CAN Bus Training
Program provides easy access to circuits to study each unique CAN Bus failure
and the corrective troubleshooting procedures through simulation
and extensive instruction with "hands-on" practice. This instruction is then followed by repetitious troubleshooting
exercises to develop confident CAN Bus troubleshooting skills.
The CAN Bus Trainer allows a
technician to experience a total of 48 CAN Bus problems in 8-10 hours of
training with hands-on practice troubleshooting to find the problem.
This training program is designed for home study or tech school curriculum.
This is the first time this type of CAN Bus troubleshooting
training and repair information is available to service technicians.

Even without the CAN Bus circuit board
H-PCB200, the technician/student workbook, H-WB200 is an excellent training aid to explain
how CAN Bus works, how CAN Bus circuits fail and the troubleshooting
techniques needed to identify and repair CAN Bus problems. There
are over 85 pages and over 40 illustrations and schematic diagrams.
The workbook is available by itself for
a Home-Study CAN Bus Workbook H-WB200, used in home-study and tech schools for advanced study in CAN Bus electrical
