Did you Google those codes?

Seems like the Cadillac Christmas tree is associated with some camshaft problem. Someone will soon chime in I'm sure.

Good Morning Vdub4,

I'm sorry to hear you're getting numerous error codes with your Escalade ESV. I can understand how concerning this might be. Were you planning to take it to a GM certified dealership for a diagnosis? If I can be of any assistance please let me know. Just send me a private message with your full contact information, VIN, mileage and the name of your preferred dealership. I hope to hear from you soon.

Katie O.
