Hi All,

My 2004 Tundra double cab has a parasitic load that I traced to the ECU-B fuse which I believe protects these systems:

155091


I found a wiring diagram. It appears the ECU-B fuse runs to the ACC CUT RELAY and then to the Engine Control Module.

Pulling the ACC CUT RELAY did not resolve the parasitic load.

Any guidance is appreciated.

Video of load test with and without fuse (the measurement is milivolts, not watts or amps as I mistakenly state).

Thx
