3.11

DESCRIPTION AND OPERATION

ed03297

Battery voltage is constantly monitored by the BCM and

1

speedometer. Any voltage readings outside of normal para-

meters set a DTC.

DTC B2271

3

The BCM monitors [259] terminal 1 for battery power.

DTC B2271 is displayed when battery voltage is less than 9.0V.

DTC B2272

The BCM monitors [259] terminal 1 and the speedometer

monitors terminal 5 for battery power.

•

DTC B2272 (BCM) is displayed when battery voltage is

greater than 16.1V for longer than 5 seconds.

•

DTC B2272 (Speedometer) is displayed when battery

Diagnostic Tips

High voltage DTC may set when the vehicle is placed on an

unapproved constant current battery charger, on fast charge,

for a long period of time.
