Kia Sedona (2008 year). Instruction — part 54

INSPECTION PROCEDURE

1. PREPARATION

Refer to PREPARATION OF INSPECTION.

2. CHECK FIS CIRCUIT

1. Measure resistance between the terminal 1 of FIS harness connector and the terminal A 23 (21) of

SRSCM harness connector.

2. Measure resistance between the terminal 2 of FIS harness connector and the terminal A 22 (20) of

SRSCM harness connector.

Specification (resistance): below 1 ohms

Fig. 15: Checking FIS Circuit

3. Is the measured resistance within specification?

YES



Check Front Impact Sensor.

NO



Repair or replace the wiring harness between the FIS and the SRSCM.

3. CHECK FRONT IMPACT SENSOR

1. Replace the front impact sensor (FIS) with a new one.



Refer to FRONT IMPACT SENSOR (FIS) .

2. Install the DAB module and connect the DAB connector.

3. Connect the connectors of the PAB, SAB, CAB, BPT, FIS and SIS.

4. Connect the SRSCM connector.

5. Connect the battery negative cable to the battery.

6. Connect a Hi-Scan (Pro) to the data link connector.

7. Turn the ignition switch to ON and check the vehicle again.

Does Hi-Scan (Pro) indicate any DTC related to FIS?

YES



Go to next step.

NO



Replace the Front Impact Sensor (FIS).

4. CLEAR THE DTC AND CHECK THE VEHICLE AGAIN

DTC B1346 (1ST STAGE) DRIVER AIRBAG RESISTANCE TOO HIGH; DTC B1347 (1ST STAGE)
DRIVER AIRBAG RESISTANCE TOO LOW

DTC DESCRIPTION

The Driver Airbag circuit consists of the SRSCM, Clockspring and the Driver Airbag (DAB) which has two
squib circuits. The SRSCM sets above DTC (s) if it detects that the resistance of DAB squib is too high or low.
