Battery-protection cut-out on Whynter FM/BCD models with the Secop electronic unit. Identical chart to Norcold DCX, Dometic CRX, Vitrifrigo. Almost always supply-side wiring on a Whynter portable (cigarette-socket contact resistance is the #1 cause).
What to check, and in what order, is in the app. The flow Secop BD Compressor Fault — Universal 5-Code Chart (Dometic CRX / Vitrifrigo / Whynter) walks this code step by step with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
