Troubleshooting Instructions Part 2 (controller failure indication code):
CURTIS1268 controller There is two methods to make diagnosis: one is hand holder programmer,
have a troubleshooting the source of range through the indication code on controller; another is get the
troubleshooting information from the LED indicator on the controller.
Programmer diagnosis
The programmer express full of trouble shooting information with brief work, it was showed on the
manual, the input/output status was showed on the testing manual.
The history manual of diagnosis provides all the troubleshooting list after last clean of history
manual, we suggest you check and clean all troubleshooting history file when you do the maintenance
each time.
For example: if the car can not move forward, the way of repairing will be:

3. Choose testing manual, observe the input/output status for forward, if the "FORWARD
INPUT" is OFF on the testing manual, then there is some failure on the forward switch or the
switch cable connection.
4. Check or replace the cable of forward switch. Test it again, if the programmer displays the
forward switch is ON and the car is workable then it means the problem has been solved.
