: Illumination of the "Airbag," "Service," or "ABS/ESP" lights on the instrument cluster. Instrument Messages
The "New" used Ni-Zn because it offered energy density (55 Wh/kg) that was double the lead-acid batteries of the era. In theory, the DF104 New could travel on a single charge—a figure that would remain competitive until the GM EV1 in 1996.
A major cause identified in recent diagnostic forums is water leaking into the passenger compartment, often near the passenger-side airbag module area or behind the dashboard. This water intrusion corrodes the connectors and damages the electronic modules controlling the cabin fans. 2. CAN Bus Communication Failure
The power module that regulates fan speed can fail, providing incorrect resistance or sending no voltage to the fan, triggering a "mismatch" or "communication" fault. Troubleshooting and Repairing the DF104 Fault
Given the lack of a verifiable subject, I cannot produce a factual essay on a non-existent engine.
Dirt or debris on the wheel ring can sometimes trigger related codes. Inspecting the wiring:
The directive was simple: Create a practical urban electric vehicle using French technology—specifically, the advanced nickel-zinc (Ni-Zn) batteries being developed by the aerospace firm .
To clear a new DF104 code permanently without blindly swapping expensive modules, follow this logical diagnostic process:
CAN Line Communication Failure (No communication with specific safety nodes) Airbag warning light permanently lit. 🔍 Root Causes of a New DF104 Fault
Confirm the steering wheel angle sensor sits flush against the steering column control module. Note: Ensure it is not accidentally plugged into an inert headlight switch support channel next to the sensor cluster. 3. Clearing Memory and Software Re-initialization
