The lamp shall turn on for 6 seconds during the initialization phase and be turned off afterward.
To alert the driver, the warning lamp shall turn on for 6 seconds and off for one second then on continuously after the operating voltage is applied if any active fault exists.
1.
Active faults exist.
2.
No active faults or crash records exists.
