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
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
000 00
(3,2)
(3,2)
(3,2)
The codes are listed in
indicate an illuminated LED. For suggestions
about possible causes of the various faults, refer to
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
for suggestions covering a
wide range of possible faults.
