DIAGNOSTICS AND TROUBLESHOOTING
The 1243
GEN
2 controller provides diagnostics information to assist technicians
in troubleshooting drive system problems. The diagnostics information can be
obtained by observing the appropriate display on the handheld programmer, the
fault message displayed on the Spyglass gauge, the fault codes issued by the
Status LED, or the fault display driven by the controller’s fault outputs (Fault 1
and Fault 2). Refer to the troubleshooting chart (Table 7) for suggestions
covering a wide range of possible faults.
PROGRAMMER DIAGNOSTICS
The handheld programmer presents complete diagnostic information in plain
language. Faults are displayed in the System Faults Menu, and the status of the
controller inputs/outputs is displayed in the Monitor Menu.
Accessing the programmer’s Fault History Menu provides a list of the
faults that have occurred since the fault history file was last cleared. Checking
(and clearing) the fault history file is recommended each time the vehicle is
brought in for maintenance.
For information on 1311 programmer operation, see Appendix B. If you
are using the older 1307 programmer, refer to existing documentation.
SPYGLASS DIAGNOSTICS
The eight-character LCD on the Spyglass displays a continuous sequence of
hourmeter, battery state-of-charge, and fault messages.
Fault messages are displayed using the same codes that are flashed by the
LED (see Table 8). For example, the LED flashes 3,2 for a welded main
contactor:
¤¤¤ ¤¤ ¤¤¤ ¤¤ ¤¤¤ ¤¤
( 3 , 2 ) ( 3 , 2 ) ( 3 , 2 )
and the corresponding Spyglass message is:
CODE 32
When a fault message is being displayed, the red Fault LED (labeled with
a wrench symbol) flashes to catch the operator’s attention.
The LCD also displays a warning when either service timer expires. The
service warning is not considered a fault and the red Fault LED does not flash.
The word
SERVICE
is displayed for about 20 seconds on each key-on, after the
hourmeter is displayed.
The Spyglass is available in 3-LED and 6-LED models; see Figure 21.
