E-Pretensioner Unit
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
The E-pretensioner unit operates the motor-driving controls based on F-CAN data it receives from the ACC unit, VSA modulator-control unit, and the PCM. Also the E-pretensioner unit receives seat belt buckle switch signals from the SRS unit by an interactive communication function. The E-pretensioner unit has a self-diagnostic function, and if it detects a malfunction, it sends its information to the SRS unit. The SRS indicator is then turned on by the SRS unit.
