FOB Unlock Event:

A FOB (Key Fob) is used to unlock the H/L (Handle Lock).

The system records which specific FOB performed the unlocking operation.

Battery Voltage Check:

After the FOB unlocks the H/L, the system checks the battery voltage level of that specific FOB.

MAIN SW ON Detected:

Once the user turns the MAIN SWITCH ON, this condition becomes relevant.

This ensures the vehicle is about to be used, so the system alerts the user early.

Low Battery Detection Logic:

If the system detects that the FOB used to unlock the H/L has low battery, then a warning is triggered.

System Indication:

The SMART IND (Indicator) will blink exactly 5 times.

This serves as a visual warning to the user about the FOB’s low battery status.

No Other FOBs Considered:

The warning is only shown if the FOB that actually unlocked the H/L has a low battery.

If another FOB (not used to unlock H/L) has low battery, no indication is given.

Purpose:

This early warning helps users replace the FOB battery before it fully drains and causes communication failure.
