Kia Sedona (2008 year). Instruction — part 68

Fig. 66: Driver Airbag - Schematic Diagram

SPECIFICATION

DAB resistance: 1.6-4.7 ohms

TERMINAL & CONNECTOR INSPECTION

Refer to TERMINAL & CONNECTOR INSPECTION.

INSPECTION PROCEDURE

1. PREPARATION

Refer to PREPARATION OF INSPECTION.

2. CHECK DAB RESISTANCE

1. Connect the Dummy and the Dummy Adapter on DAB harness connector.

2. Measure resistance between the terminal 9 and 10 of SRSCM harness connector (A).

Specification (resistance): 1.6-4.7 ohms

CAUTION: Never attempt to measure the circuit resistance of the airbag module

(squib) even if you are using the specified tester.

3. Is the measured resistance within specification?

YES



Check open circuit.

NO



Replace the Driver Airbag (DAB) module.

3. CHECK OPEN CIRCUIT

1. Measure resistance between the terminal 2 of DAB harness connector and the terminal 9 of

SRSCM harness connector (A).

2. Measure resistance between the terminal 1 of DAB harness connector and the terminal 10 of

SRSCM harness connector (A).

Specification (resistance): below 1 ohms

YES



Check short circuit.

NO



Repair or replace the wiring harness between the DAB and the clockspring or between the
clockspring and the SRSCM.

4. CHECK SHORT CIRCUIT

1. Measure resistance between the terminal 1 and 2 of DAB harness connector.

Specification (resistance): ohms

2. Is the measured resistance within specification?

YES



Go to next step.

NO



Repair or replace the wiring harness between the DAB and the clockspring or between the
clockspring and the SRSCM.

5. CLEAR THE DTC AND CHECK THE VEHICLE AGAIN

Refer to CLEAR THE DTC AND CHECK THE VEHICLE AGAIN.

DTC B1485 (2ND STAGE) PASSENGER AIRBAG RESISTANCE TOO HIGH; DTC B1486 (2ND
STAGE) PASSENGER AIRBAG RESISTANCE TOO LOW

DTC DESCRIPTION

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