I have an 05 Trailblazer 4.2 I6. recently my antitheft has been locking me out inconsistently for always different amounts of time. i have read alot on passlock issues and followed a similar article in how to diagnose my passlock sensor. upon doing these tests though i recieved different results and am unsure as to what they may indicate. when i tested my Red/White to Orange/Black i got 13.3v at IGN0,IGN1,&CRANK. the Yellow to Orange/Black read 4.3V in all positions. this was while the vehicle was running. when it did the no start R/W to O/B read 12.1v in all positions, and Y to O/B read 4.2. from what i understand the yellow is supposed to dorp to an unknow value upon IGN1&CRANK. not sure what it indicates, any help would be great.
