The DF002-0110 fault code is a diagnostic trouble code (DTC) commonly found in vehicles from manufacturers like Renault, Peugeot, and Citroën. It typically indicates a problem with the transmission pressure regulation or a related issue in the Transmission Control Module (TCM), often tied to the CAN bus network. This guide explores the symptoms, causes, and solutions for transmission issues, highlighting the effectiveness of OBD2 scanners like the iCarsoft CR MAX and CR Eagle for diagnosis.
1. What Does DF002-0110 Code Mean?
The DF002-0110 code generally points to a fault in the transmission hydraulic system or a control module failure within the TCM. It suggests an issue with pressure regulation or communication errors over the CAN bus network, which can disrupt gear shifting and vehicle performance.
2. Symptoms of DF002-0110 Code
- Check Engine Light or Transmission Warning Light illuminated
- Erratic or delayed gear shifts
- Transmission slipping or hesitation
- Vehicle stuck in limp mode
- Unusual noises from the transmission
3. Common Causes
- Malfunctioning Transmission Control Module (TCM)
- Faulty pressure solenoid or hydraulic system
- Damaged wiring or connectors in the CAN bus network
- Low or contaminated transmission fluid
- Software issues leading to control module failure
