DIAGNOSTICS AND TROUBLESHOOTING

The 1228 controller provides diagnostics information to assist technicians in
troubleshooting drive system problems. The diagnostics information can be
obtained in two ways: reading the appropriate display on the programming
device or observing the fault codes issued by the status LED.

PROGRAMMER DIAGNOSTICS

The programmer presents complete diagnostic information in plain language.
Faults are displayed in the Faults/Diagnostics Menu, and the status of the
controller inputs/outputs is displayed in the Monitor Menu.
Additionally, the Fault History file provides a list of the faults that have
occurred since the history file was last cleared. Checking (and clearing) the history
file is recommended each time the vehicle is brought in for maintenance.
Refer to the troubleshooting chart (Table 3) for suggestions about possible
causes of the various faults.
For information on the programmers, see Appendix C. If you are using
the older 1307 programmer, refer to existing documentation.

LED DIAGNOSTICS

During normal operation, with no faults present, the status LED is steadily on.
If the controller detects a fault, the status LED provides two types of informa-
tion. First, it displays a slow flash (2 Hz) or a fast flash (4 Hz) to indicate the
severity of the fault. Slow-flash faults are self-clearing; as soon as the fault is
corrected, the vehicle will operate normally. Fast-flash faults ("
are considered to be more serious in nature and require that the keyswitch be
cycled to resume operation after the fault is corrected.
After the severity indication has been active for 10 seconds, the status
LED flashes a 2-digit fault identification code continuously until the fault is
corrected. For example, code "1,4"—low battery voltage—appears as:

The codes are listed in Table 2. Refer to the troubleshooting chart (Table 3)
