Troubleshooting and Testing
The log will display the stored and active faults. Active faults that occur after the screen is
displayed will not appear until a screen update is requested. After making the necessary
repairs, use the Clear DTCs button to clear the fault. Cycle the ignition and restart the program
to check for faults that are still active.
Use the Generate DTC Report button to generate a fault report (.txt file). The DTCs report can be saved on
the connected PC.
Most faults require an ignition cycle and/or test drive above 5 mph (8.05 kph) to verify the fault
resolution. Also check the ABS warning lamp to ensure the system functions correctly.
Counter Information: Displays the counter information such as pump motor hrs, ABS events, ESC events,
ATC events, etc.
Air Gap Size: Displays the wheel speed sensor air gap condition.
Components
Activate Valves:
Allows the valves to be selected and activated in a sequence typically used for bleeding
the brake system. The software will execute a process of opening and closing the selected valves for a set
time and the activation status will appear in the box below the valve selection box.
ESC: Displays ATC status, event counters, ESC measurement data, steering ratio data and ESC End of
Line (EOL) Calibration procedure.
Miscellaneous Components: Allows the ABS and ATC lamps to be toggled on and off. Also allows ABS
pump activation. All vehicles may not have an ATC lamp.
Enable ATC: Allows enabling of ATC.
Disable ATC: Allows disabling of ATC. The control status on the ATC Brake and ATC Engine fields on the
Main Screen will display “N/A” instead of “Off.”
EOL
Many of the features found in the EOL section of this menu must be used in conjunction with
the instructions listed in the Brake Bleed Procedures of this manual updated continuously.
Bleed Procedure: This screen allows functions such as pump flush and the ESC switching sequences for
the front and rear axles to be utilized.
System Checked Bit: This is a function that must be performed after flashing parameters into the unit’s
ECU. It performs a checksum to detect if there are any errors which may have been introduced while
flashing.
Parameters
Save Parameters to File:
Allows saving of most recent parameter settings to PC as a (.par) file.
Utility
Active Outputs:
This screen allows for the engineering testing of individual ABS valves (in and out), the
ABS and ATC lamps, the ABS pump and other individual components.
Reset ECU: Allows the resetting of the ECU clearing at installed software and parameters.
Engineering Data: This screen displays the status of the STC, DTC and EBD systems along with the
system type and master cylinder pressure.
