What does this fault code mean?
The supplemental restraint system module (SRS) checks the internal parts of the occupant weight sensor (OWS). The code is stored when the internal parts stop working and the incorrect value has persisted for a while. The cause is either a damaged occupant weight sensor or a sensor that has not been calibrated.
Possible causes
- Damaged occupant weight sensor (OWS)
- Calibration not completed
What you can do
- 1Read the code, clear it, and see whether it returns
- 2If the code SRS-B00A054 is also stored, have that fault dealt with first; then clear the codes and check whether the occupant weight sensor codes return
- 3Have a workshop replace the occupant weight sensor if needed and calibrate it after replacement
- 4Do not work on the airbag system yourself; have a workshop check it
