components with the help of technician input. Please note that the Installation Test is intended as a tool
to assist the quality control process at the vehicle manufacturer. However, this test must not be
relied on as the sole validation check of proper brake system installation. The vehicle manufacturer
must ensure appropriate process controls are in place in the manufacturing process to completely
validate the vehicle brake system prior to vehicle shipment.
Figure 26
22 Customize The Customize screen allows the technician to customize some of the features in the installation test.
Warning: The tests conducted must match the features of the vehicle being tested. With each
vehicle, it is important to confirm that the correct sets of features are being verified. Typically the
Bendix® ACom® Diagnostics software will save the features used on the previous test, so if the
software was used on a vehicle with different features during its last use, the customized features
must be re-assessed and changed to match the new vehicle.
To complete any necessary changes, simply click in the box next to a desired test name — a check mark
will appear — to request that the test be performed. Similarly, you may uncheck boxes to skip those tests.
Mandatory tests are displayed on the screen in gray, optional tests appear in black.
You may use the screen to:
• Re-arrange the order of the tests
• Save a report in TXT or HTML format
• Save a report using the VIN as the filename
• Create a folder in which to save the report (the program will prompt to ask for a folder and file name)
• Select to show wheel speeds in either MPH or RPM

If there are any active Diagnostic Trouble Codes (DTCs) on the Electronic Control Unit (ECU), the
installation will not run, and the technician will be notified by a message. Active DTCs must be corrected
and cleared before the Installation Test can be performed. 23 Installation Test requirements The chart below indicates which tests are available for an Electronic Control Unit (ECU). If there is a YES
next to the test name, that specific test is required in order to complete the Installation Test. If there is a
“NO” shown for a test, that test is not required in order to complete the Installation Test. If there is an “N/A”
shown for a test, this indicates that the ECU does not support that specific test. As a result, the test will not
appear in the Installation Test list. For the wheel speed sensors, at least one of the two sensor tests is
required – indicated by the word “ONE” in the chart. Bendix recommends that the full sensor test be run,
although the simple sensor test is an acceptable option.
All the tests in the table below refer to Bendix® EC-60™ Controllers.
24 ECU Information The ECU Information Test is a mandatory test. It must always be run. The test provides the technician with
information about how the ECU is configured.
Figure 28 25 Installation Configuration The Installation Configuration field displays a graphic – and specifics – about the expected configuration.

within ±5 degrees of vertical.
NOTE: The installation angle test will only be available if the ECU supports Bendix® Trailer Roll Stability
Program (TRSP).
Figure 33 30 Sensor Tests The Wheel Speed Sensor output is tested using the screen shown below.
Figure 34 31 Pressure Sensor Test The Pressure Sensor Test reads the pressures applied to the Electronic Control Unit (ECU) through the
brake system. The potential number of pressure sensors supported is dependent upon the ECU.
Figure 35 32 P21 / P22 Delivery Test The P21/P22 Delivery Test will check that the module is correctly plumbed to the brake chambers and test
the brake delivery air pressure. Park the vehicle on level ground and chock the wheels. During this test, the
delivery pressure should match the control pressure. After applying the brakes, the technician must verify
that the delivery and control pressures are the same. Bendix® ACom® Diagnostics system will then release
the brakes and the technician must verify that the brakes have released. The final step is for the Bendix
ACom Diagnostics software to re-apply the brakes.

36 Configuration Window – ACB The Configuration Window is used to display ACB sensor configuration information including the mounting
offset, stationary object warning, alignment value and following distance setting configuration number.
ACB Sensor Configuration Mounting Offset The ACB Sensor mounting offset provides the horizontal offset relative to the vehicle’s longitudinal axis. A
positive value indicates an offset to the left of the vehicle’s longitudinal axis (driver’s side) and a negative
value indicates an offset to the right of the vehicle’s longitudinal axis (passenger side). The offset range is
± 500 mm (19.69 inches). The physical mounting location of the sensor cannot exceed ± 500 mm. Changes
to the sensor location from the OEM-installed position requires Bendix Engineering approval.
Stationary Object Warning The Stationary Object Warning field provides the technician with an audible alert for stationary objects
within the vehicle path. Stationary object warnings will be enabled (ON) or disabled (OFF).
Alignment Value The ACB sensor alignment value provides the angle calculated by the system that the sensor is found to be
pointed (laterally) away from the vehicle’s longitudinal axis.
The smaller the alignment angle, the better forward vehicle tracking performance. A positive value indicates
that the sensor is currently aimed to the right side of the vehicle’s longitudinal axis (passenger side). A
negative value indicates the sensor is currently aimed to the left side of the vehicle’s longitudinal axis
(driver’s side). The acceptable alignment range is ± 1.4 degrees, but if the alignment value is greater than
±0.8 degrees, it is recommended to adjust the sensors aim. See the ACB Service Data Sheet for full details
of the sensor adjustment procedures.
