SUBJECT
Traction Control Warning Illuminated; Fault Code 5DF3 Stored
MODEL
Cooper with manual transmission (R55, R56)
Cooper S with manual transmission (R55, R56)
Cooper S JCW (R55, R56)
SITUATION
The customer may report that the traction control warning illuminated while driving. Depending on the vehicle's equipment level, fault code 5DF3 "Interface: DME/DDE signal fault" may be stored in either the Automatic Stability Control Module (ASC) or the Dynamic Stability Control Module (DSC).
INFORMATION
The fault code 5DF3 is set in the ASC/DSC module whenever an implausible signal is received from the Engine Control Module (DME). Therefore, it is important to check the DME fault memory when diagnosing the ASC/DSC fault code 5DF3. If the DME fault memory contains fault code 2FC1 "Clutch switch signal", then the clutch switch input to the DME should be checked. If the clutch switch is not functioning properly, continue diagnosing the clutch switch electrical circuit. If the clutch switch is operating properly, then the most likely cause of the fault is driver error. If the driver rests his or her foot on the clutch pedal while accelerating, the fault will be stored. If operator error is suspected, please inform the customer accordingly.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
