I'm working on the HVAC system and the computer is reading B1676 battery voltage out of range along with ground circuit shorts connecting to the a/c system. All the actuators and everything else is working fine but now its reading this code. So I was wondering if we needed to change the battery or is there a ground that may need checking that would be causing this code to show up. The a/c system is working other than the cold air isn't getting colder, it stays cool. So after diagnosing it again these codes are showing up B1676,B1253,B1261,B1967,B2429,B1264,B1265. I have worked on it several times and after clearing the issues up it comes back reading this and not blowing cold.
B1676 Battery voltage out of range
B1253 In vehicle temperature sensor short circuit to ground
B1261 A/C solar radiation sensor circuit short to ground
B1967 Driver heater core discharge temperature sensor short circuit
B2429 Passenger heater core discharge temperature sensor short circuit to ground
B1264 Floor door actuator circuit failure
B1265 Cold airbypass door actuator circuit failure
This is all memory codes, you have a shorted out climate control module the reason for battery voltage out of range is due to a shorte circuit system
