(1) Connect the devices as shown in the system connection diagram (reference Section 3.1). (2) Before activating the power supply, check the switches on the Dengen Box: - B+, ACC SWs: OFF (levers must be down). - Ignition key SW: Set to Door OPEN or OFF. - Rev, ILL, PKB SWs: OFF (levers must be down). - TEST BITS SWs (B0/B1/B2): Either Eng. Eval mode (Down/Up/Up) or XTP mode (Up/Up/Down). - VEHICLE SPEED SW: Set to the stop status. (3) Supply 13.5 V DC from the power supply to the Dengen Box. (4) Turn the B+ switch on. This will supply the battery + power to each unit. (5) Turn the key switch clockwise to the ACC position. The splash screen (Ford logo) will soon appear in the display, and the system will begin to operate. The signal from the key switch is input to DCU, converted to an MS-CAN command, and input to each module, such as ACM: The power supplies of each module, including ACM, will then turn on or off.. 3.4.2 Power OFF procedure. vi. co. (1) Turn the ignition key SW counterclockwise to the Door OPEN position. The display screen will soon disappear, and the system will end operations. (2) Make sure that the ammeter of the power supply reads 10 mA or less before turning the B+ switch off. The current will not decrease immediately because the HDD is operating inside the ACM: Turning the B+ switch off without checking the reading on the ammeter could cause the HDD to crash..
