Air Brake Charging System Troubleshooting
1.0  Oil Test Card 
Results
Not a valid test.
Discontinue using this test.
Do not use this card test to diagnose compressor 
"oil passing" issues. They are subjective 
and error prone. Use only the Bendix Air 
System Inspection Cup (BASIC) test and the 
methods described in this guide for advanced 
troubleshooting.
The Bendix
®
 BASIC test should be the 
de
fi nitive method for judging excessive 
oil fouling/oil passing. 
 (See Appendix A, 
on page 27 for a flowchart and expanded 
explanation of the checklist used when 
conducting the BASIC test.)

How to use this guide:
Find the 
symptom(s)
 that you see, then move to the right 
to
fi
 nd the possible causes (“

”) and 
remedies (“
What you should do
”).
Review the warranty policy before performing any intrusive 
compressor maintenance.  Unloader or cylinder head gasket 
replacement and resealing of the bottom cover plate are 
usually permitted under warranty.  Follow all standard safety 
procedures when performing any maintenance.
Look for:
Normal - Charging system is working within 
normal range.
Check - Charging system needs further 
investigation.

WARNING! 
Please READ and follow these instructions to 
avoid personal injury or death:
When working on or around a vehicle, the following general 
precautions should be observed at all times.
1.  Park the vehicle on a level surface, apply the parking 
brakes, and always block the wheels.  Always wear safety 
glasses.
2.  Stop the engine and remove ignition key when working 
under or around the vehicle.  When working in the engine 
compartment, the engine should be shut off and the ignition 
key should be removed. Where circumstances require that 
the engine be in operation, EXTREME CAUTION should be 
used to prevent personal injury resulting from contact with 
moving, rotating, leaking, heated or electrically charged 
components.
3.  Do not attempt to install, remove, disassemble or 
assemble a component until you have read and thoroughly 
understand the recommended procedures.  Use only the 
proper tools and observe all precautions pertaining to use 
of those tools.
4.  If the work is being performed on the vehicle’s air brake 
system, or any auxiliary pressurized air systems, make 
certain to drain the air pressure from all reservoirs before 
beginning ANY work on the vehicle.  If the vehicle is 
equipped with a Bendix
®
 AD-IS
®
 air dryer system or a dryer 
reservoir module, be sure to drain the purge reservoir.
5.  Following the vehicle manufacturer’s recommended 
procedures, deactivate the electrical system in a manner 
that safely removes all electrical power from the vehicle.
6.  Never exceed manufacturer’s recommended pressures.  
7.  Never connect or disconnect a hose or line containing 
pressure; it may whip. Never remove a component or 
plug unless you are certain all system pressure has been 
depleted.
8.  Use only genuine Bendix
®
 brand replacement parts, 
components and kits. Replacement hardware, tubing, 
hose,
fi
 ttings, etc. must be of equivalent size, type and 
strength as original equipment and be designed speci
fi
 cally 
for such applications and systems.
9.  Components with stripped threads or damaged parts 
should be replaced rather than repaired.  Do not attempt 
repairs requiring machining or welding unless speci
fi
 cally 
stated and approved by the vehicle and component 
manufacturer.
10. Prior to returning the vehicle to service, make certain all 
components and systems are restored to their proper 
operating condition.
11. For vehicles with Automatic Traction Control (ATC), the ATC 
function must be disabled (ATC indicator lamp should be 
ON) prior to performing any vehicle maintenance where 
one or more wheels on a drive axle are lifted off the ground 
and moving.
