You can try jumping the low pressure switch to get it to cycle.

Do you have a vacuum pump to evacuate the system?
Need to do this before you charge.

I generally agree with this and would if it is a C60 (manual system).
But the FSM (at least my 92) states:
"The C68 system may disengage the the compressor and set a 09 code (low Freon) fault code during the recharging procedure if the low pressure cycling switch is not bypassed."
