7 — DIAGNOSTICS & TROUBLESHOOTING
LED Fault Categories
In the “fault category” format, the LED indicates one of three categories. Be-
cause the category does not provide diagnostic information, you will need to
use the programmer to find out what the problem is.
Table 4 STATUS LED FAULT CATEGORIES
CATEGORY INDICATION
No faults present Status LED shows heartbeat.
Warning Status LED is flashing at 2 Hz rate.
Fault Status LED is continuously on.
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. For example, the LED flashes 3,2 (
¤¤¤ ¤¤
) for a main contactor fault,
and the corresponding Spyglass display is
CODE 32
.
PROGRAMMER DIAGNOSTICS
The 13XX programmer presents diagnostic information in plain language. All
currently set faults are displayed in the Diagnostics Menu (see second column
in the troubleshooting chart), and the status of the controller inputs/outputs
is displayed in the Monitor Menu.
TROUBLESHOOTING CHART
The troubleshooting chart, Table 5, provides suggestions covering a wide range
of possible faults.
Whenever a controller fault is encountered and no wiring or vehicle fault
can be found, shut off KSI and turn it back on to see if the fault clears. If not,
shut off KSI and remove the J1 and J2 connectors. Check the connectors for
corrosion or damage, clean them if necessary, and re-insert them.
