GENERAL INFORMATION
CUSTOMER CAUTIONS
1. Be sure to proceed with airbag related service only after approx. 30 seconds or longer from the time
the ignition switch is turned to the LOCK position, key is removed from the vehicle and the negative (-)
battery cable is disconnected from the battery. The airbag system is equipped with a back-up power
source to assure the deployment of airbags when the battery cable is disconneted during an accident.
The back-up power is available for approx. 150ms.
2. When the negative (-) battery cable is disconnected from the battery, the clock and audio system's
memory will be wiped out. So before starting work, make a record of the contents of the audio system's
memory. When the work is finished, reset the audio system and adjust the clock.
3. Symptoms of malfunction of the airbag system are difficult to detect, so the diagnostic codes become
the most important source of information when troubleshooting.
4. When troubleshooting the airbag system, always inspect the diagnostic codes before disconnecting the
battery.
5. Never use airbag parts from another vehicle. When replacing parts, replace them with new parts.
6. Never attempt to disassemble and repair the airbag modules (DAB, PAB, CAB, PT), clock spring and
wiring in order to reuse them.
7. If any component of the SRS has been dropped, or if there are cracks, dents or other defects in the
case, bracket or connector, replace them with new ones.
8. After work on the airbag system is completed, perform an SRS SRI check. The airbag indicator lamp
can be triggered by faults in other circuit in some cases. Therefore if the airbag indicator lamp goes on,
be sure to erase the DTC codes using the Hi-Scan Pro just after repairing or replacing the troubled
parts, including the fuse.
9. Especially when carring out body welding, never fail to disconnect the battery's negative (-) terminal.
The side airbag of SORENTO has curtain-shape when deployed.
