ASD 3S162 Sensor test groups on 820-3476 retina board,
On older versions of ASD, it would tell you which sensor failed. TS0P, VP0R, IC0R, etc. It allowed for streamlined identifying and troubleshooting of the problem. On the 820-3476 logic board for the late 2013 A1502 13.3" Retina, you get "test group 5 failed" or "test group 7 failed." I have no idea what test group 5 or 7 can correlate to, or mean. The schematic gives the same useful interpretation of sensors that older schematics did, but the Apple Service Diagnostic which used to tell one which sensor has failed has become completely useless. Holding down "D" and running that diagnostic is even worse, it tells me to go to an Apple Authorized Service Provider. I feel like this is a spiteful troll on Apple's part; god knows THEY won't have a clue which sensor has failed or how to fix it.... Before I go reading pulses to the SMC on every SMBUS line and recording & comparing to an identical board to find the out of spec sensor... help?
