What is CID 100:
CID 100 refers to an issue with the vehicle’s transmission system. Specifically, it indicates a malfunction with the transmission control module (TCM), which can lead to poor shifting, loss of acceleration, or failure to switch gears properly.
Why This Happens:
- Faulty transmission control module (TCM).
- Shorted or damaged wiring in the TCM circuit.
- Low transmission fluid levels.
- Loose or corroded connectors.
- ECM failure to properly interpret TCM data.
How to Fix It:
- Inspect the transmission control module (TCM) for damage or malfunction.
- Check wiring and connectors for visible damage or corrosion.
- Ensure proper transmission fluid levels and condition.
- Reprogram or replace the TCM if necessary.
- Perform a full system diagnostic check to ensure proper transmission function.
How to Avoid It Before It Happens:
- Perform regular transmission system checks.
- Inspect transmission fluid levels regularly.
- Keep connectors clean and secure.
- Perform routine diagnostics to monitor TCM health.
- Clue’s fleet management software helps monitor transmission systems and prevent shifting or performance issues.
