Trailer Roll Stability System (TRSP) Sensors

NOTE: The TRSP sensors will only be available if the

ECU supports TRSP.

The TRSP sensors allow the technician to monitor the

lateral acceleration sensor, axle load and installation

angle data.

Figure 20

Control buttons for graph:

Start will start the data collection.

Stop will stop the data collection.

Rewind will rewind the data.

Forward will forward the data.

Plus the graph type can be bar graph, line graph which

is the default or 3D.

Control Buttons for TRSP Sensors

Open ﬁ le will open an existing TRSP ﬁ le.

Load ﬁ le will load an existing TRSP ﬁ le.

Help will open Help page.

Close will close TRSP window.

Sensor Calibration

The sensor calibration allows the lateral acceleration

sensor to be calibrated. The trailer needs to be on a

level surface for the calibration. Press “Start” to begin

the calibration process, use the “Yes, No or Cancel”

choices to answer any questions. ACom will recalibrate

the lateral acceleration sensor, clear any DTCs and

display the actual sensor value.

Figure 21

Control Buttons for Sensor Calibration:

Start - Starts calibration

Yes - Acknowledges that the technician is in agreement

with the question asked

No - Technician disagrees with the question asked

Cancel - Stops the calibration

Close - Closes the calibration window

Component Test Screen

The component test screen provides a mechanism to

allow the technician to test various components within

the system such as: wheel speed sensors, modulators,

pressure sensors and the lateral acceleration sensor.

Plus the component test will allow the technician to

perform some system tests such as battery voltage,

ABS indicator lamp, Aux I/O and axle load.

Note: Before performing the component test make

sure the vehicle is parked on a level and ﬂ at ground.

Figure 22

The component test screen supports various tests;

each tab will be populated with the tests which

are supported by the ECU. The tabs are Sensors,

Modulators, Pressures, TRSP system (if equipped)

and Miscellaneous. The technician needs to select the

appropriate tab for the component to test. Once the

tab is selected, on the left side of the screen a list of

available tests will be displayed, the technician needs

to select the test i.e. S-C sensor test. After the test

is selected on the right side of the screen will display

instructions for the technician on what needs to occur

before the test can run.

Sensors

This test will allow the technician to test the wheel

speed sensor output. The test will display the correct

number of sensors which the ECU is conﬁ gured for.

The technician will need to select which sensor to test,

then press Start/Next button to start the test and follow

the instructions. The program will ask the technician,

“Did the ECU respond correctly?” The technician

needs to acknowledge if the test was successful by

selecting the green check mark indicating “yes” or the

red circle with a line indicating “no.”
