4-2.7. Diagnostics and Troubleshooting.

The motor controller provides diagnostics information
to assist in troubleshooting drive system problems.
The diagnostics information can be obtained in two
ways:
• Reading the appropriate display on the programmer
• Observing the fault codes issued by the Status LED.
The Status LED is located on the side of the control-
ler. See Figure 4-1 for location of the LED on the
controller.
4-2.7.1. LED Diagnostics
During normal operation with no faults present, the
Status LED flashes a single flash at approximately 1
flash/second. If the controller detects a fault, a 2-digit
fault identification code is flashed continuously until
the fault is corrected. For example, three flashes fol-
lowed by two flashes is code "3,2" appears in the LED
code table as:
000 00 000 00
(3,2)

3.0, 3.0,

000 00
(3,2) (3,2)
The codes are listed in
4-3 indicate an illuminated LED. For suggestions
about possible causes of the various faults, refer to
Table 4-4 Troubleshooting Chart.
Operational faults, such as an over-temperature situa-
tion, are cleared as soon as the operation is brought
within range. Non-operational faults, such as a throttle
fault, usually requires the brake or key switch to be
cycled after the problem is remedied.

4-2.8. Programmer Diagnostics

With a programmer, diagnostics and troubleshooting is
more direct than with the LED alone. The programmer
presents complete diagnostic information in plain lan-
guage - no code to decipher. Faults are displayed in
the Diagnostic Menu, and the status of the controller
inputs/outputs is displayed in the Test Menu.
The following 4-step process is generally used for
diagnosing and troubleshooting an inoperative vehicle
using the programmer:
1. Visually inspect the vehicle for obvious problems:
2. Diagnose the problem:
3. Test the circuitry with the programmer:
4. Correct the problem.
Repeat the last three steps as necessary until the
vehicle is operational.
Refer to the Table 4-4
