FCC 000168.18 – Instrument Unit, Supply Voltage (BAT) Too Low
FCC 000168.18 (FCC 168.18)
Code: 000168.18
Shortcode: 168.18
Description:
This error code indicates that the supply voltage to the Instrument Unit (BAT) has fallen below 9 volts. This condition often points to a deeply discharged battery, a faulty alternator, or poor electrical connections.
Reaction:
The control software will have limited or no functionality due to the undervoltage condition, significantly affecting the instrument unit’s performance and reliability.
Recommendations:
- Inspect Battery Condition: Check if the battery is deeply discharged or defective and replace it if necessary.
- Examine Alternator and Charging System: Ensure the alternator is charging the battery properly and the charging system is working correctly.
- Check Electrical Connections: Look for loose, corroded, or damaged connections that could cause a voltage drop.
- Perform Load Testing: Conduct load tests to verify the battery and charging system’s performance under operational conditions.
Note:
Consistently low voltage can damage the Instrument Unit and other electrical components. Prompt attention and resolution of this issue are crucial to maintaining system integrity.
