600SEL 1992

Well guys after scanning and resting all of the stored, I have these codes that continued to be stored after erased:

004 Air mass sensor with hot wire B2/4
010 Idle speed recognition EFP, TPM, LLR constantly to ground
006 Intank manif. assist..retr. head restraints vacuum too low

The last code (006) was in the PSE section. Additionally, I have:

LH2 System is not connected or open circuit in diagnostic cable
AB does not answer

I'm happy because the car back to live again but having a problem with understanding these codes, kindly can you tell me what shall I do? Again thank you
