After you have diagnosed and corrected the problem, you should clear the diagnostic history file. This allows 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.
This section shows you different modes you can use on the PMT to troubleshoot this lift truck.
Access 1. Turn the key switch OFF and disconnect the battery connector.
