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.
