Water Sensor
Water sensor is a thermistor that detects engine coolant temperature to operate the blower speed to LO when water temperature is less than 50.
1. Check that there are water sensor fault code (15,16) by
using self-diagnosis function.
3. Check that measured resistance value among water sensor terminals is as shown in the right side graph. Notice Measure resistance value by soaking the sensor in the ice water and check changes in resistance values after soaking
it in the very hot water.
4. If resistance value is out of specification, replace the water sensor.
5. Install the sensor and turn the ignition switch to ON position and check that voltage between No. 7a terminal of the water
sensor and body (-) is 5V.
6. Check current between the No. 7a and 7b connector terminals of the water sensor and the No. 3 and 5 connector terminals of the airconditioner control unit and repair the wire if defective.
2. Disconnect water sensor 2-pin connector that installed on
the heater unit of inner instrument panel and remove the
water sensor.

SUPPLEMENTAL RESTRAINT SYSTEM(SRS) 8B-21
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.
