Cadillac Jim Posted May 10, 2014 Report Share Posted May 10, 2014 B0429 Temperature Control #3 Rear Circuit Range/PerformanceB1004 Keep Alive Memory (KAM)P0410 Secondary Air Injection (AIR) SystemP0463 Fuel Level Sensor Circuit High VoltageB1327 Vehicle system voltage below 9.0 volts The check engine light is probably because of the P0410. But the B1327 means that the battery is being pulled down below 9 Volts when you start the car, which can throw all kinds of bogus codes. You need to get your battery fully charged and clear the codes. If any come back, then you know that the problem is real. Note that Goran W picked up that your battery was down. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
