MEMORY BACKUP BATTERY REPLACEMENT

The replaceable memory backup battery on the
17FB144 or 17FB147 card will require replacement if
voltage is low when performing "CPU Battery Checks"
test or if during truck operation an event code appears
on the DID display as follows:
17FB147: Event Number 095 (BBRAM Battery
Low)
17FB144: Event Number 633 (BBRAM Battery
Failure)

To replace the battery on either card:

card and locate the green plate with the battery,
near the card edge. (See Figure 3-3.)

installed within 5 minutes of removal of the old
battery.

the battery assembly (3) to the mounting bocks.

tioned for proper polarity. Reinstall screws.
