What does it mean?
U2195 is a Network (CAN bus, module communications) fault code. It indicates: Data Circuit Message .
Symptoms
- Steering wheel controls, indicators, wipers or cruise switches stop working
- Steering column lock will not release or will not engage on equipped vehicles
- No-start condition on vehicles with an electric column lock
- Warning lamps and messages on the instrument cluster
- Horn or steering wheel buttons work only intermittently
- Scan tool cannot reach the column module
Likely causes
- Loose or corroded connector at the steering column module
- Wiring damaged in the column area or in the clock spring circuit after steering wheel or airbag work
- Column module without proper power feed or ground
- Break in the bus wiring between the column module and the receiving module
- Column module replaced without being configured to the vehicle
- Water running down the column from a windscreen or bulkhead leak
- Internal failure of the steering column module
How to fix it
- Read all modules and check whether the column module answers
- Watch the live data from the column switches while operating each one in turn
- Remove the lower column shroud and inspect the connectors and the clock spring wiring
- Measure supply voltage and ground at the column module
- Test bus continuity between the column module and the gateway or body module
- Check for water tracking down the column and fix the leak first
- Configure the module after replacement; replace only once wiring and supply are proven good
