I was sitting at idle in my driveway trying to troubleshoot an A/C problem and I got the HDC fault system unavailable error (no other messages on the cluster).
I believe the ABS light also came on.
Battery is BRAND new. Literally just put in an interstate AGM 3 days ago (battery date 5/20).
Brake light switch is also brand new. installed a new one last week.
I got the following 2 codes using my GAP tool:
C1A77-16 (0B) Valve relay supply circuit - general electrical failure - circuit voltage below threshold
C1A86-04 (0B) Commutation valve 1 - general failure information - system internal failure
I could not clear either one of these codes with the tool.
Anyone know what these codes point to?
Any way this battery could be defective from the factory?
Didn't see anything like this when I did a search but if anyone has any links to past posts please let me know.
Thanks!
