1. The procedure to input information is listed:
   1. The figure that is blinking on the character display (2) can be changed. In order to change the figure, you should depress the boom priority mode switch (23) or the swing priority mode switch (24).
      • The figure that is blinking increases (Boom priority mode switch (23) )
        
        
        
      • The figure that is blinking decreases (Swing priority mode switch (24) )
      The character position that is blinking can be shifted by depressing the fine control mode switch (25) or the user mode switch (26).
      
      • The character position that is blinking shifts to the right (Fine control mode switch (25) ).
        
        
        
      • The character position that is blinking shifts to the left (User mode switch (26) ).

1. After you enter the security code, the service mode is activated by depressing and holding the following switches for 2 seconds or greater: travel alarm cancel switch (22), fine control mode switch (25) and user mode switch (26). The service mode is automatically activated 10 seconds after the security code is entered.

1. Now, the "Service Mode" is activated and the character display (2) will display "10" on the left two character positions and "1" on the right character position.

Note: Refer to the chart of Service Codes for selecting the functions for the "Service Mode".

Mr. Hystat put this together a while back. It shows you how to get into the service mode in a B model excavator.

He also has one on the throttle control backup system.

Which engine speed sensor did you replace ? There is one in the flywheel that the hydraulic ecm uses. That one has to have clearance set.

The 345 was built as both B & C models John. C-model production appears to have ended somewhere around 2007-2008.

SIS also lists a 345D model but it appears to have been a Japan-only machine, which of course could always end up somewhere else in the world as a grey market import.

I have a 345DL, in the states.

RAJ 00252. I haven't looked to see where it was made.

Nige said:

It's strange, there is no information on the 345D in the resources I look at. The engine for RAJ00252 was built in Mossville so it stands to reason that the excavator would have come out of the Cat Aurora Plant.

I finally woke up and thought about how to check this and opened my serial number program which lists the point of origin for each serial number. 345D machines were made in Japan, Belgium and the United States. Prefixes for US made machines are EEH, MLK, and YEE. The only Belgium serial number shows as KFH. All the rest were made in Japan.

Look on the serial number tag on the RH base of the cab. It tells the country of manufacture.
