Thanks Lee

 

The 1055 does not appear to be a valid code.
For the 1016 and 1064, my service manual shows the following:

DIC Onboard Diagnostics Show DTCs U1016, U1064 and U1096 in History #PI00043 - (Jun 19, 2002)
DIC Onboard Diagnostics Show DTCs U1016, U1064 and U1096 in History
.

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Condition/Concern:
DTCs U1016, U1064 and U1096 may be present when scrolling through the onboard diagnostics via the instrument cluster Driver Information Center (DIC).

Recommendation/Instructions:
This is a normal software function as long as the DTCs have a history status upon ignition cycling. No repair attempts should be made.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.

and:

The 1016 is a loss of communication with the PCM (see attached)
the 1064 is a loss of communication with the BCM (see attached)

I can not find anything in my service manual for 1088, 1176 or 1160
