Kia Sportage: Seat Belt Buckle Switch (BS) | Passive Occupant Detection System (PODS)

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / Restraint / SRSCM / Seat Belt Buckle Switch (BS) | Passive Occupant Detection System (PODS)

Description and Operation

 Description

The SRSCM shall monitor the status of the driver and front passenger seat belt buckle. The SRSCM provides one pin each for the driver and front passenger seat belt buckle status input. The seat belt buckle circuit operates from internal boost voltage supplied by the SRSCM, and uses chassis ground for the signal return. The buckle status shall modify the SRSCM deployment. If the buckle status is unbuckled, the corresponding pretensioner will not be deactivated.

Tightening Torque: 39.2 ~ 53.9 N.m (4.0 ~ 5.5 kgf.m, 28.9 ~ 39.8 lb-ft)

4. Install the front seat assembly. (Refer to the Body group-Front seat)

5. Reconnect the battery negative cable.

6. After installing the seat belt buckle switch, confirm proper system operation:

  1. Тurn the ignition switch ON: the SRS indicator should be turned on for about six seconds and then go off.

Passive Occupant Detection System (PODS)

Description and Operation

 Description

The system is intended to classify the occupancy status of the front passenger seat in a motor vehicle based upon the measured force on the bottom seat cushion.

The system also communicates to the SRSCM whether to allow or inhibit the deployment of the passenger air bags and/or pretensioner based upon this status.

The System also measured dynamic responses of the occupant. This information is used to identify when a child seat is cinched down tightly with the seat belt, and to also determine if the seat is unoccupied.

However, the dynamic measurements are not intended, nor capable of monitoring the seating position of the occupant, nor can they determine the proximity of the occupant to the inflator modules.

The system should not be confused with an occupant position recognition system, or any other occupant proximity sensor.

The Passive Occupant Detection System (PODS) utilizes bladder placed between the passenger seat cushion and suspension to measure the occupant's loading force on the passenger seat. The sensor mat is connected to smart digital pressure sensor which is mounted under the seat pan. The quantitative force determined by the system is compared to a given threshold for determination of passenger airbag suppression.

Repair procedures

Removal

1. Disconnect the battery negative cable, and wait for at least three minutes before beginning work.

2. Remove the front passenger seat assembly. (Refer to the Body group - Seat)

3. Remove the seat cushion as an assembly. (Refer to the Body group - Seat)

Installation

1. Install the PODS equipped seat cushion assembly.

(Refer to the Body group - Seat)

2. Install the front passenger seat assembly.

(Refer to the Body group - seat)

3. Reconnect the battery negative cable.

4. After installing the PODS, confirm proper system operation:

  1. Тurn the ignition switch ON: the SRS indicator should be turned on for about six seconds and then go off.

    Telltale lamp will nun on for 4 seconds and be turned off for 3 seconds. After the 7 seconds, it shall remain off if the PODS does not require suppression and the passenger airbag is enabled.

NOTE

Be sure to perform PODS reset with scan tool after replacing PODS equipped seat cushion.

 PODS Re-zero procedure

You should perform PODS Re-zero procedure after service or replacement about all part of the passenger seat.

1. Ignition "OFF", connect GDS.

2. Ignition "ON" & Engine "OFF", select Airbag system and "PODS Reset" mode.

3. The GDS will show the two PODS RESET function steps.

3. The GDS will show the two PODS RESET function steps.

  1. Erase PODS diagnostic codes.
  2. PODS initialization.

CAUTION

CAUTION

This step must be done PODS re-zero, when the front passenger seat is empty.

4. Press the OK button to erase the PODS related diagnostic codes.

5. Press OK button to initialize the PODS.

5. Press OK button to initialize the PODS.
