10 NO CONSOLE DISPLAY
If the console is not showing any lights, such as warning lights, backlighting, etc. it is most likely
missing power. Start with the following:
Ensure that no lights, warning
lights, or backlighting is visible.
Check wiring harness
and central unit.
Check if power is being supplied by the
central unit. Measure on the green connector
(Pin 1 is +Ub 12V and Pin 2 is GND).
Check fuses in console: one (F6) is located on
the connection board (mounted to the inside of
the housing) which protects the override key
switch function and the bar-gragh. The main fuse
(F1) is locate on the console processor board.
Check for power on connector
X6 of the connection board. (Pin
1 is +Ub 12V and Pin 2 is GND).
Is power
being
supplied?
?
Follow power from this connector to the console computer
board, connector X1. (Pin 1 is +Ub 12V and Pin 2 is GND).
Connecting
cable is
loose or
defective.
If voltage is present on all
pins and connector are in
place, but you still do not get
any console lighting.
Ensure TxD LED is on (located in center of
the computer board and is normally blinking
when the console is communicating).
Check fuse F1 again. Make sure all connectors
are correctly in place.
