diagnostic codes.
The indicator lamps can be used to identify an active
code by flashing in a sequence that will identify the
active code. The active code that is flashed by the
indicator lamps is only the component identifier (CID).
The indicator lamps cannot identify the fault with the
component. The active code that is flashed by the
indicator lamps is not a Failure Mode Identifier (FMI).

When the Flash Code feature is activated the
indicator lamps will flash the codes of all active
codes. Activation of the indicator lamps is achieved
by cycling the keyswitch OFF and ON twice within
3 seconds.
There will be a delay of 2 seconds before the lamps
start to flash the identity of any active code.
An active CID with two digits will be flashed in
the following sequence. There will be a number of
flashes. The number of flashes will equal the first
digit. There will be a delay before a second number
of flashes. The second number of flashes will equal
the second digit. For example, a CID code of 41 will
be four flashes, a delay and the one flash. A three
digit CID code will have two delays between the
sequence of flashes. A four digit CID code will have
three delays between the sequence of flashes.
Each flash of the lamp will be 0.5 seconds long.
There will be a delay between each flash of 0.3
seconds.
