Entering and Exiting Diagnostic Mode
Before entering diagnostic mode, verify that all fueling transactions are complete. You cannot
access this mode while a transaction is in progress.
1. Unlock and lower the rear door of the Series 1000.
2. As you look into the rear of the unit, the MPU PCB is mounted on the left side. The
diagnostic switch is in the center of the rear edge of the MPU PCB. Under normal use, it
should be in a down (off) position. Place the switch in an up (on) position. The LCD
displays: ENTER TEST 0-9. This indicates the system is ready to execute any of the tests.
3. To select a test, press the keypad number for the test and press ENTER. The number
appears on the LCD display as you type it. If you type an incorrect number, press CLEAR
and enter a different number.
NOTE: The following pages contain specific operating instructions for each test.
4. To exit diagnostic mode, return the diagnostic switch to the down (off) position. You can turn
off the diagnostic switch at any point, even during a test. When diagnostic mode is off, the
LCD display alternates between the idle message and ENTER CARD (card systems),
ENTER VEHICLE (cardless systems), or INSERT KEY (FleetKey systems).
5. Close and lock the rear door.
