id0102f3156200

DTC P0562:00

Battery voltage low input

DETECTION CONDITION
•  The PCM monitors the battery voltage. If the battery voltage is less than 8 V, the PCM determines that there is a malfunction in the battery and the battery signal system.
Diagnostic support note
•  The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle.
•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Poor battery positive terminal
•  Generator connector or terminal malfunction
•  Drive belt misadjustment
•  Battery malfunction
•  Generator malfunction
•  Short to ground in wiring harness between generator terminal D and PCM terminal 1BD
•  Short to ground in wiring harness between generator terminal P and PCM terminal 1BK
•  PCM connector or terminal malfunction
•  Open circuit in wiring harness between generator terminal D and PCM terminal 1BD
•  Open circuit in wiring harness between generator terminal P and PCM terminal 1BK
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
