Description:

This diagnostic trouble code (DTC) alerts to a condition where the supply voltage for the RTC (Real-Time Clock) falls below 9 volts. Low voltage can compromise the RTC’s ability to keep accurate time, which is critical for event logging and system synchronization. The likely causes include a depleted battery, insufficient charging, or high resistance in the electrical circuitry.

Reaction:

The system may issue warnings or reduce functionality to conserve power and protect the RTC from further voltage drops.

Recommendations:

• Check and Replace Battery If Necessary: Ensure the battery is capable of holding a charge and replace if it is found to be deficient.
• Inspect the Charging System: Confirm the charging system is functioning correctly to provide a steady and adequate power supply.
• Review and Repair Electrical Connections: Investigate for loose or corroded connections that could impede proper voltage delivery and rectify any found issues.

Note:

Regular maintenance of the electrical system, including the charging system and battery, is crucial for preventing low voltage conditions and ensuring the functionality of critical components like the RTC.
