MAINTENANCE
There are no user serviceable parts in Curtis 1212S controllers. No attempt
should be made to open, repair, or otherwise modify the controller.
Doing so may damage the controller and will void the warranty. However, it
is recommended that the controller’s fault history file be checked and cleared
periodically, as part of routine vehicle maintenance.
DIAGNOSTIC HISTORY
The handheld programmer can be used to access the controller’s fault his-
tory file. The programmer will read out all the faults that the controller has
experienced since the last time the history file was cleared. The faults may be
intermittent faults, faults caused by loose wires, or faults caused by operator
errors. Faults such as HPD or overtemperature may be caused by operator
habits or by overloading.
After a problem has been diagnosed and corrected, clearing the history
file is advisable. This allows the controller to accumulate a new file of faults. By
checking the new history file at a later date, you can readily determine whether
the problem was indeed completely fixed.
