After trouble codes have been displayed, the service mode can be used to perform several tests on different systems one at a time. Upon completion of trouble code display, a specific system may be selected for testing. Following trouble code display, the first available system will be displayed (i.e. ECM). When selecting a test, there are 4 available actions to be taken:
- Pressing the OFF button will stop the system selection process and return the display to the beginning of the trouble code sequence.
- Pressing the LOW fan button will display the next available system selection. This allows all system selections to be displayed.
- Pressing the HIGH fan button will select the displayed system for testing.
- Pressing the BI-LEV button will exit diagnostics and return to normal IPC and ECC operation.
