LIN NODE BENCH OBSERVATION RECORD
Purpose: map a documented node and compare expected versus observed states in a controlled
fixture.
Hardware/schematic, controller, transceiver/SBC, firmware and exact manuals:
Frame schedule, identifier, publisher, length, checksum and signal units:
Supply/ground/probe arrangement approved for the bench:
State | rail/reset/enable expectations | measured current | bus/application behavior:
Startup:
Normal:
Standby/sleep:
Valid wake and recovery:
Missing-frame timeout:
Illustrative whole-node budget: (20 mA x 0.1 s + 0.03 mA x 9.9 s)/10 s = 0.2297 mA, about
5.51 mAh/day. If idle current is 1 mA, average is 1.19 mA and daily charge 28.56 mAh.
Fictional values; include actual transients and all loads.
Observed fault, one change, repeated result and saved trace:
Remaining limits; vehicle integration requires its own qualified process:
