| DETECTION CONDITION |
- The PCM monitors the voltage of back-up battery positive terminal. If the PCM detects battery positive terminal voltage below 6 V for 5 s
when the battery voltage is more than 8 V
, the PCM determines that the backup voltage circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot is available.
