Default help understanding "C"and"H" codes

from what i understand when reading codes from the dic,the codes with an "H" behind it stands for"history",and "C" stands for"current".
my question is do i need to worry about the "history" codes,are just the
"current" codes here are the ones that i pulled up(p060H,C),(p1652H,C),(c1226H),(38-rtd no comm),(c2110H,C)i know what the codes stand for,i need suggestions or solutions on how to repair the problems,please comment on these

the C codes are more important to pay attention to, as they are still happening. an H code indicates something which happened but is not happening anymore. they can still be very helpful in diagnosing a problem however.

there are some codes which are automatically H and never get a C. I know some of the power seat related codes do this.

The first code you posted is missing a digit, they should all have 4 number in them.

P1652 Powetrain Induced Chassis Pitch Output Circuit
C1226 RF Excessive Wheel Speed Variation
C2110 Right Rear TPM Sensor Malfunction
rtd no comm - the real time damping module is not communicating with the system, this is not necessarily a bad thing, your car might not have rtd installed.
