# Service bulletin SB\_747

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

IMMI, the creator and supplier for Rolltek and other Supplemental Restraint System \(SRS\) products, is implementing design changes due to obsolescence of select parts. Most recently, the AB8 Front Impact Protection \(FIP\) sensors are no longer available and cannot be ordered. If you believe there is an issue with the AB8 FIP sensor, please contact customer service for technical support. We now require all active and inactive diagnostic codes be included when starting a Technical Incident for an SRS issue. Having the codes at the start of the incident ticket process will provide efficient troubleshooting and increase the accuracy of the suggested corrective actions.
