Together
New Seminar
Reveals Solutions
to Top Service
Concerns
What can cause an air conditioning
compressor to suffer an early death,
one of the most common service
concerns for service centers? An
­insufficient oil charge? Moisture in the
system? Contaminated refrigerant oil?
Wrong oil type? All of the above?
The compressor is the heart of the
A/C system, pumping refrigerant and
refrigerant oil through the system. A
low oil level or the wrong oil type or viscosity will accelerate compressor wear.
Moisture can lead to internal c­ orrosion.
Contaminated refrigerant oil can clog
the orifices, screens and control valves
and deteriorate the rubber hoses. So
the answer is all of the above. But the
answer also is system flushing, which
will remove the old oil and most contaminants from the A/C system and
components, and checking the appropriate Service Information to determine
the correct amount and type of oil
before installing a new compressor.
The new ACDelco seminar,
Today’s Top Service Concerns
(S-DS11-17.01SEM), covers some of
the top service concerns affecting
many aftermarket shops, such as A/C
compressor service. The seminar offers
technical solutions as well as tips to
ensure a proper repair.
Information presented in the seminar
reviews the service issue, some of the
typical causes, and how to properly
address the concern. Case studies provide a descriptive investigation of each
issue along with the details needed to
determine the fundamental reasons for
a cause and correction.
Here’s a quick look at a few of the
topics covered in the three-hour seminar.
Power Steering
Power steering system failure may be
caused by improper pulley removal and
installation, re-using old O-rings, improper fluids, and other factors. The seminar
presents detailed information on power
steering fluid and flushing procedures.

New Seminar Reveals Solutions
Batteries
A drained battery that is capable of
holding a charge may be caused by a
parasitic drain. A parasitic draw test,
along with a circuit/system test, is
­covered in the seminar.
Brakes
The keys to a successful brake
s­ ervice involve making the right call on
rotor refinishing, cleaning all components and proper assembly. Burnishing
the brake pads and rotors should be
performed whenever the brake rotors
have been refinished or replaced, or the
brake pads have been replaced.
Rotating Electrical
Causes of charging or starting system
failure can include high resistance in the
battery cables or an oil leak that enters
an electric motor. Before replacing
components, replace damaged cables
or terminals and repair any oil leaks. In
addition, tips on starter motor installation, drive belt diagnosis, and automatic
tensioner ­diagnosis are covered.
Water Pumps
Water pumps may fail due to contamination and corrosion. Failure to flush
the cooling system and replace the
coolant can lead to repeat failure. When
­installing a new water pump, clean all
sealing surfaces, do not strike the water
pump shaft (this will cause damage to
the new water pump), and turn the hub
by hand to check for rotation.
Oil Filters
If the oil regulating valve and the
bypass valve on the engine become
“sticky” from dirt and contaminants,
too much pressure may enter into the
filter and cause the element to collapse
or bulge out. If a damaged filter element is discovered, perform a complete
inspection of the filter bypass valve and
the pressure regulator valve.
Suspension
Installing air shocks/struts requires
cycling the shock/strut to spread lubricant inside the diaphragm to avoid binding. Inflate the air diaphragm through
the air fitting until the shock/strut fully
extends. Leave the shock/strut fully
extended to make it easier to install.
Fuel Pumps
A poor connection between the body
harness electrical connector and the fuel
pump can result in drivability c­ oncerns.
Installation of the fuel pump connector
is quick and easy with the proper tools.
Check each splice for electrical continuity using a digital ohmmeter — a reading
very close to zero ohms indicates the
crimps are good.
New CONNECTION
The full CONNECTION site also can
be accessed from the menu, providing
users with complete access to all of the
functionality and features of the parts
­ordering tool.
The mobile site is available on
­ ultiple handheld devices, making
m
it possible for technicians to order
parts without leaving the service bay.
Information entered on the mobile site
also is available on the user’s desktop computer. To get started, log in
at www.acdelcoconnect.com on your
mobile device.

Emissions
When removing spark plugs from
aluminum heads, allow the engine to
cool. The heat of the engine in combination with a spark plug that is still hot
may cause the spark plug threads to
be damaged or strip the cylinder head
upon removal. An improperly torqued
spark plug can cause a compression
loss-misfire.
Body Electrical
Fretting corrosion is a buildup of
insulating, oxidized wear debris that
can form when there is a small motion
between electrical contacts. When diagnosing intermittent electrical c­ onditions,
check for poor connection/terminal
retention, micro motion, or a connector,
component or wiring harness that is
not properly secured, resulting in movement.

New Tool Helps Diagnose CAN Bus Faults
GM has released new diagnostic software to help technicians identify a starting point in diagnosing faults in a CAN
bus (GM also calls this a LAN) by looking at how connectors and wiring are
working or not working. With this information, diagnostic time can be reduced
for intermittent electrical conditions.
The new Data Bus Diagnostic Tool
is an application that uses existing
GM Multiple Diagnostic Interface
(MDI) or Bosch Mastertech Vehicle
Communication Interface (VCI) tool
functionality. You will use your MDI or
VCI tool, a computer with access to
the web-based Techline Information
System (TIS2Web), and an active
TIS license.
Determine Physical Layer Status
• Double opens
CAN buses have characteristic voltages under different fault conditions.
By monitoring bus voltage, it’s possible
to identify whether or not the bus is
physically OK. It’s also possible to identify the type of fault that’s present (CAN
LO/HI open, short, ground offsets, etc)
by monitoring bus voltage.
• Single wire shorts to power/ground
Three-In-One Application
• Power faults (open supply, blown
fuse, broken enable line, etc)
The Data Bus Diagnostic Tool is actually three sub-applications in one. Each
one has its own tab on the application's
graphic interface.
To download the software, click the
GDS 2 software application icon on
the TIS2Web home page. A prompt to
install the software will appear.
Aftermarket subscribers can access
GDS2 by logging in to TIS2Web at
www.acdelcotds.com.
Due to the increased functionality and
additional value of GDS2, there will be
a small price increase for future GDS2
subscriptions. The short-term software
fees will increase $2 in the US for the
3-day and monthly subscriptions, and
$25 for annual subscriptions.
Diagnostic Aids
If there's a high speed communication issue and 20 U codes set in every
module, those DTCs aren't very useful
in narrowing down the concern. The
new Data Bus Diagnostic Tool software
will show counts of each module and
how often it's NOT communicating.
This very quickly identifies the problem
module, and provides a quick point of
diagnosis for checking the connectors,
terminals and wiring for that module.
It's proven extremely useful in field
testing for these issues.
Localizing the Fault
The application actively queries all
possible diagnostic addresses to see
what modules are on the bus. Modules
that respond are on the ‘good’ part of
the bus. Modules that don’t respond
are on the ‘bad’ part of the bus.
The application doesn’t know what
modules a vehicle is equipped with,
so it can’t report which modules are
missing. Compare the list of modules
displayed in the application against that
vehicle’s schematics in the appropriate
GM Service Information.
A. Detected State
B. Measured Voltage
C. Message Monitor
Detected State – Identifies which
control modules are responding to
diagnostic requests, and identifies the
physical state of the vehicle bus being
diagnosed (open, short, ground offset,
etc)
In performing these functions, this
tab does three things:
• Single wire open/short (i.e., the
wire is broken and the far side is
shorted)
• CAN LO shorted to CAN HI
• Ground offsets (i.e., bad ECU
grounds)
Detected State identifies the physical
state of the selected bus.
Using the Detected State, if a bus
has a break point in communication,
some modules on the “good” side of
the faulted bus will respond very intermittently. When diagnosing intermittent
faults, pay attention to the ECU with
the longest response time and use the
electrical schematic to identify the modules that did not communicate during
the Detected State procedure.
1. It provides a diagnostic starting
point. All possible ECUs are sent
simultaneous requests at a rate of
250 ms. The application tracks and
displays the longest time it takes for
each ECU to respond to a diagnostic
request to help with intermittent
faults.
2. It tries to identify what's going on
with the wires that make up the
bus (OK, CAN LO/HI open, CAN LO/
HI shorted to ground, ground offsets, enable line open/blown fuse/
power faults, etc.).
3. It provides audible feedback. You
can set the application to beep
­continuously when a fault is
­detected or when the bus appears
electrically OK.
The states that can be detected
include:
•OK
• Single wire opens (CAN LO Open,
CAN HI Open)
4
Measured voltage on two pins of a CAN.
Measured Voltage – Provides a low
speed voltage trace of the selected
bus, CAN LO and CAN HI. Due to current MDI limitations, it refreshes at
about 1 ms, so it's not as fast as an
oscilloscope. It also won't let you see
the individual bits in a CAN frame (CAN
frames take about 0.25 ms to transmit).
It is, however, very visually obvious
when a fault is introduced or removed.
Message Monitor – Passively monitors bus activity to help diagnose battery drain problems. This tab works on
Single Wire CAN only.

New Glow Plug Bore Reamer Available
Glow plug installation may
become difficult if carbon builds
up in the bore, which can reduce
the size of the bore and potentially
damage the tip of a new glow
plug. To address this condition,
a new Glow Plug Bore Reamer
(EN-51249) was recently released.
It’s now available for 2001-2010
Chevrolet Kodiak; 2001-2009 GMC
TopKick; and 2001-2015 Chevrolet
Express, Chevrolet Silverado
2500/3500, GMC Savana, and
GMC Sierra 2500/3500 models
equipped with a 6.6L Duramax®
diesel engine (RPOs LB7, LLY,
LMM, LGH or LML).
When using the
tool, first apply a
light coat of wheel
bearing grease to
the inside of the
flutes. The grease
will retain the
removed carbon
and help keep any
debris from falling
into the engine.
Remove the reamer occasionally to
clean any carbon
from the flutes and
re-apply the grease.
Apply grease to
the inside of the
flutes to retain the
carbon.
The reamer is
the same height as
an installed glow
plug.
Glow Plug Bore Reamer
Carbon may build up around
(EN-51249)
the glow plug tip during normal
engine operation. When it’s time
to replace the glow plugs, this buildup can make it difficult to
correctly install a new glow plug and may result in damage to
the new plug.
With the reamer
in the glow plug
bore, turn it by
hand with a ratchet while applying slight pressure in the bore.
The reamer’s hex drive will be at the same height as the hex
drive of a fully installed glow plug when the bore is completely cleaned.
The Glow Plug Bore Reamer can be used to remove the
carbon. It is non-threaded so that it can work on multiple
model years.
To order the Glow Plug Bore Reamer, call
1-800-GM-TOOLS.

New Tool Helps Diagnose CAN Bus Faults –
continued from page 4
The biggest difference between Message Monitor and
Detected State is that it passively monitors the bus, while
Detected State actively queries the bus. Actively querying
ECUs will make some of them stay awake. Obviously, keeping ECUs awake would be a bad thing if you're trying to
diagnose a power
moding fault.
In the case of a vehicle with a continually faulted bus, you
might want to make the application beep when the detected
fault goes away.
This tab will tell
you which ECUs
have communicated in the past
1.5 seconds, how
long it's been
since ECU last
Message Monitor passively
monitors the bus.
communicated
(if more than
1.5 seconds have elapsed), and how many times the ECU
was the first ECU talking on the bus (the bus is considered
'asleep' after 30 seconds of idle time).
The application tracks the longest time it takes for each
control module to respond to a request. Control modules
which take longer to respond than their peers were/are likely
on the faulted side of the bus.
The application reacts to bus changes quickly (approximately 100 ms). Wiggle connectors and listen for a beep.
Tracking Intermittent Faults
If the application is started on a faulted bus and a module
responds midway through the test, it will appear with a
non-zero time value in this field.
This number will not reset unless the reset (eraser) button
is clicked or the bus being tested is changed.
More Information
Audible Feedback
The application can be configured in the Settings function to
beep when either a fault is detected or when the bus appears
electrically OK. Different beep strategies can be used in different scenarios.
In the case of a vehicle with a suspected intermittent bus
fault, you might want to make the application beep on faults
so that it will beep when the fault is detected.
