DTC P0562

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 the first drive cycle.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• Drive belt condition
• Generator malfunction
• Open circuit in wiring harness between generator terminal D and PCM terminal 9
• Open circuit in wiring harness between generator terminal P and PCM terminal 77
• Short to ground in wiring harness between generator terminal D and PCM terminal 9
• Short to ground in wiring harness between generator terminal P and PCM terminal 77
• Poor connection of connector at positive terminal
• Poor battery positive terminal
• Terminal malfunction
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
