Selecting The System

Following the display of trouble codes, the first available system will be displayed (i.e. PCM?). While selecting a system to test, any of the following actions may be taken to control the display:

1. Depressing the "OFF" button the ECC panel will stop the system selection process and return the display to the beginning of the trouble code sequence.
2. Depressing the "LO" button on the ECC panel will display the next available system selection. This allows the display to be stepped through all system choices. This list of systems can be repeated following the end of the system list.
3. Depressing the "HI" button on the ECC panel will select the displayed system for testing.
