What is CID 24:
CID 24 refers to an issue with the vehicle's battery system. The ECM detects a voltage problem, such as undercharging or overcharging, which can lead to poor engine performance or potential failure to start.
Why This Happens:
- Faulty battery or alternator.
- Damaged or shorted wiring in the charging system.
- Loose or corroded connectors.
- Voltage regulator failure.
- ECM failure to process charging system data.
How to Fix It:
- Inspect the battery and alternator for proper function.
- Test the charging system voltage output to ensure proper charging.
- Check wiring and connectors for visible damage or corrosion.
- Replace the faulty battery or alternator if necessary.
- Ensure ECM is receiving the correct charging data.
How to Avoid It Before It Happens:
- Regularly test the battery and alternator for proper voltage output.
- Inspect charging system wiring for wear and damage.
- Keep connectors clean and secure.
- Clue’s asset tracking services monitor battery and charging systems to prevent failures before they affect engine operation.
