PROPEL CIRCUIT BOARD TROUBLESHOOTING

Curtis 1228 LED DIAGNOSTICS- Basic and Cylindrical
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 information.
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 ("." in Table 2) are
considered to be more serious in nature and require that the key switch 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: one LED flash, followed by a pause,
then 4 LED flashes, and then repeats.
