Description:

This diagnostic trouble code, JDL 000964.13, is triggered when the control unit does not recognize a valid date or time. This fault indicates issues with the timekeeping function of the control unit or its synchronization with external time sources.

Reaction:

When this error code is triggered, the equipment may experience issues with functions that depend on accurate time and date information, such as logging, scheduling, and GPS synchronization.

Recommendations:

Check Time and Date Settings:

• Verify that the time and date settings on the control unit are correct. Manually adjust them if necessary.

Inspect RTC (Real-Time Clock) Battery:

• Check the RTC battery (if present) in the control unit. Replace it if it is depleted, as it is responsible for maintaining the time and date when the unit is powered off.

Update Control Unit Software:

• Ensure that the control unit software is up-to-date. Install any available updates to improve timekeeping accuracy and system stability.

Synchronize with External Time Source:

• Configure the control unit to synchronize with an external time source, such as an NTP (Network Time Protocol) server, if supported.

Consult Technical Support:

• If the issue persists after performing the above steps, consult the manufacturer’s technical support for further assistance.
• Provide the diagnostic trouble code and any relevant information gathered during the inspection.

Note:

Invalid time and date issues can affect various functions of the equipment. Regular checks and maintenance of the timekeeping system can help ensure accurate operation.
