computer issue
2000 C5 65k. Experiencing alternating display "security" "service vehicle soon" about every 10 minutes while driving. Had 1 no start. Disconnected battery waited 20 minutes started but same displays. How can I find they cause of the "service vehicle soon" display?
Thank you

No difference. Codes: SDM: U1000, U1064, 60IPC: U1160, U1176, HVAC: U1064, U1160, LDCM: U1064, A6SCM: U1255,U1064,
A1RDCM: U1064. All are "H". Was not able to clear as DTC will not go into scan. Disconnected bat. overnight, after reconect approx. 1 minute underhood light and security light on after opening drivers door. still no start. Liights went off. No power to courtesy lights, and under hood. All other manual operated switches work ok. No column lock or unlock. Battery is 1 yr. old OE Delco fully charged, cables excellent. Appreciate very much your help.
