Clear

After you have diagnosed and corrected the problem, you should clear the diagnostic history file. This allo ws the traction power amplifier to accumulate a new file of faults. By checking the new history file at a later date, you can easily determine whether the problem was completely fixed.

1.Hold the more info key, and press the program key. Release both keys after you enter the Special Program mode.

2.Scroll through the mode using the scroll display keys until “CLEAR DIAG HIST” is the top line in the display.

3.Press the more info key again. The PMT prompts you to acknowledge or cancel.

4.Press the value up key to clear the diagnostic history. Press the value down key to cancel.
