Measurement and decision sequence

  1. Record whether the symptom occurs cold/hot, at start, idle, load, speed and road condition.
  2. Compare active/pending/history DTCs and freeze-frame timelines across all modules.
  3. Verify commanded-vs-actual deviation with raw sensor signal and a physical measurement.
  4. Evaluate 12 V/DC-DC, HV/48 V, cell deviation, isolation and thermal state on the same timeline.

Misdiagnosis traps

  • Treating the first visible DTC as the root cause.
  • Failing to reproduce the same operating condition after repair.
