Cadillac Repair: 1996 Cadillac Deville Northstar, inflatable module, cadillac deville

Question
My dad's ac compressor says off. What does he need to do to turn it on? Here are the following codes that appears: PC 0153 current, No 1 PC Code, AC 1312 History, AC 1313 history, AC 1314 current  AC 1348 History, no sdm, no TCS, RS 0038 current, pz 1558 history, pz 2088 current  

Answer
PC 0153 current = Left O2 sensor slow response.
No 1 PC Code =  System OK.
AC 1312 History = A/C high side temp sensor open problem
AC 1313 history = A/C high side temp sensor short problem
AC 1314 current = Evaporator inlet temp sensor open problm
AC 1348 History = very low AC freon pressure condition
no sdm = System OK
no TCS = System OK
RS 0038 current = ELC exhaust valve short to ground/open
pz 1558 history = PZM EEPROM Checksum error.
pz 2088 current = loss of SDM serial  communication



ELC = Electronic leveling controller
PZM EEPROM = Computer Prom
SDM = Supplemental inflatable Module      


You need to put an expensive high dollar scanner on the vehicle to properly diagnose these faults.
