If you receive customer reports in the above model vehicles with the SRS warning lamp illuminated and any of the above DTCs stored, please make
note of the fault tracing information shown. To properly diagnose this issue, please follow the SRS fault tree in Star Diagnosis (SDS). This fault tree
can be found in a quick test by selecting the stored DTC. If no faults are found, the cause could be a memory card with a transponder chip has been
placed on the passenger seat. Company ID cards, notebook computers, PDAs, and other electronic equipment may contain such memory cards that
cause interference with the Baby Smart(TM) transponder. This interference can be interpreted as a fault by the SRS control unit. This condition may
be difficult to duplicate in the workshop. Please alert the customer not to place items containing memory cards on the passenger seat. Replacement of
components will not remedy the situation.
Note:
The interference from electronic components is an outside influence and not a manufacturing defect and therefore cannot be claimed under
warranty.
