AIR BAG CONTROL UNIT(AC4) Removal & Installation Procedure AC4 is installed on the center portion of the front floor tunnel.
Built-in accelerometer sensor detects collision and determines action or non-action and ignition time. Notice
Do not disassemble the AC4 to repair. If defective, replace it. AC4 should not be shocked or vibrated by dropping on the ground or bumping. Replace the AC4 with new after air bag inflation.
1. Disconnect the negative battery cable and wait for 30seconds before starting service. Notice Though battery cable is disconnected, air bag control unit will maintain backup power for 150ms and air bag can beinflated, so wait for min.30 seconds.
2. Remove the console box and center fascia panel assembly.
3. Remove the heater control switch and audio assembly.
4. Remove the lower side panel of the driver ’ s portion and glove box.
5. Remove the lower main panel.
6. Release the lock lever of the AC4 connector and disconnect the connector.
7. Unscrew 3 nuts and remove the AC4.
NoticeFor installation, horizontal position should be secured for the better changes of collision pulse between the vehiclebody and air bag control unit.
8. Installation should follow the removal procedure in the reverse order.
Inspection Procedure
1. Check AC4 case and welt bolts for crack or deformation.
2. Check connector, lock lever and terminal for deformation. NoticeReplace the AC4 with new if dust, deformation or corrosion found.
