high pressure part of condenser broken

hi while installing the new condenser, the mechanic broke the high pressure valve part of the condenser. the check engine light, awd light and vdc and slip lights came on. he erased the codes with the ob2, and thus the car revved to 5000 rpm on its own. is this normal? should i be worried? the other lights turned off but the vdc and slip lights are still on while i drove back home.

hopefully i will get a new high pressure part tomorrow. but he says its due to the ecu needing to be hooked up to the high pressure part? which caused the codes?
