also i believe my CMU is going thru the checks but i here a repetitively ticking sound from the fuse box in the engine bay. the sounds resembles the hands of a grandfather clock if i had to describe it
Cadillac Mechanic: David Craig, Auto Mechanic replied 4 months ago

ok, that why the lights are blinking.. disconnect the battery. both terminals. short them together for 30 seconds, then let them hang loose for 15 minutes. reconnect. see if that resets everything
