IBIT (INITIATE BIT) MENU
The DOT supports a built-in-Test (BIT) component, INITIATE BIT. This process detects and
isolates faults to help the user identify the operational readiness, or where necessary, identify
degraded or failed system conditions. Results of BIT failures are stored in memory.
INITIATE IBIT (L1). Running the INITIATE BIT (IBIT) allows the user to confirm all
systems are functioning. Results are shown as counts per category in the test log box in the
center of the display screen. Select INITIATE IBIT to start the process (Figure 10).
