... Any error in these codes indicates an error in the digital circuitry of the chip. Additionally, this diagnosis mode also resets the fuse-check latch. However, a remaining error conditiotion in the fuses will immediately reestablish this latch, so that the output is set to FFFFH. Data Book KP100 2003-05 ...
