rent feedbacks are out of range at Startup or when
in standby Power cycle
99 245 REAR LEFT MODULE - INTERNAL ERROR Applicable Power Module determines at Startup
that there is a problem with overvoltage/under-
voltage detection Power cycle
99 246 REAR LEFT MODULE - CAPACITOR BANK FAULT The power capacitor bank of the Power Module is
not charging properly (increasing voltage) at
Startup Power cycle
99 247 REAR LEFT MODULE - A/D FAILURE Applicable Power Module determines that an
internal Analog Input error exists Power cycle
99 248 REAR RIGHT MODULE - EEPROM FAILURE Applicable Power Module determines at Startup
that an internal EEPROM error exists or UGM fails to
successfully verify or write to/read back Indirect
