Fault 11, EEPROM Corrupt. The O2 CELL
LED flashes four times, pauses for three seconds,
and repeats (Figure 5-11).
1. This alarm can occur if the EEPROM is
changed for a later version. At power up,
the EEPROM is not updated.
2. To correct this problem, power down and
then restore power. The alarm should clear.
3. If the alarm occurs while the unit is running,
there is a hardware problem on the micro-
processor board.
4. If cycling the power does not clear the
alarm, see paragraph 6-5b, Electronic As-
sembly Replacement.
