If the Data List item Stop&Start Operating Permission (Power Management) is "NG" even after correcting a certain problem using the diagnostic troubleshooting procedures, the problem may be due to the battery charge amount being temporarily low or the battery may be deteriorated. However, there may be multiple overlapping conditions which are causing system operation to be prohibited, so make sure to always confirm all the diagnostic troubleshooting procedures.
Check whether the multi-information display displayed that the specified battery is not equipped.
The multi-information display is displayed when the voltage decreases below the minimum voltage necessary for starting the non-specified battery when stop and start control is operated.
