What does it mean?
B1417 is a Body (airbags, seat belts, body electronics) fault code. It indicates: SIS (Side Impact Sensor) Rear-Passenger Wrong ID .
Symptoms
- Airbag warning lamp illuminated, typically right after interior or accident repair work
- Rear right side and curtain protection disabled
- Code sets again as soon as it is cleared, always as current
- Fault first noticed after a salvage or non specified part was installed
- Vehicle otherwise behaves completely normally
Likely causes
- Sensor with the wrong part number fitted at the rear right location
- Rear left and rear right sensors installed in each other's positions during trim or seat work
- Used sensor from a different model, body style or equipment level
- Restraint control module replaced and never coded to this vehicle's sensor set
- Poor or corroded connection distorting the identification data exchange
- Sensor with internal damage reporting a corrupted identifier
How to fix it
- Disconnect the battery and observe the specified reserve discharge time before touching any restraint connector
- Read the part number on the installed sensor and compare it against the correct number for this vehicle and this exact position
- Confirm the rear left and rear right sensors have not been fitted the wrong way round
- Where the module has been replaced or reprogrammed, run the configuration routine so it expects the correct sensor set
- Inspect the connector under the sill or pillar trim for corrosion, water and unlatched locks that could corrupt the data
- Install a correctly specified new sensor and torque it to the body structure as required
- Clear the memory, run the system self test and verify the warning lamp goes out and stays out
