Caterpillar Hour Meter

[dashdoctor]

Hi all
Does anybody know how to reset this clock to zero? Its from a Cat mini digger 2008 302.5 model.
There is a way to program this from the manual / datasheet but it does not work.

Any help would be great

Thanks in advance

Read micro-controller MC68C908 and post the dump.
