SYMPTOM
P0562-BATTERY VOLTAGE LOW

WHEN MONITORED
Engine Running. RPM greater than 1152.

SET CONDITION
The battery sensed voltage is 1 volt below the charging goal for 13.47 seconds. The PCM senses the battery voltage turns off the field driver and senses the battery voltage again. If the voltages are the same, the code is set. One trip Fault.

POSSIBLE CAUSES
- Good trip equal to zero
- B+ circuit high resistance
- Generator ground high resistance
- Generator operation
- (Z1) generator field ground circuit open
- (K20) GEN field control circuit shorted to ground
- (K20) GEN field control circuit open
- PCM
