Passive Occupant Detection System
- Follow all safety precautions when working on pyrotechnic components. Refer to RESTRAINT SYSTEM COMPONENTS, SAFETY PRECAUTIONS AND TESTING PROCEDURES .
The passenger occupant detection system service kit is precalibrated and must not be disconnected. The service kit consists of:
- Seat Occupied Recognition Control Module -J706-
- Seat Occupied Recognition Pressure Sensor -G452-
- Passive Occupant Detection System Mat
- Seat cushion
- Wiring harness between the seat occupied recognition control module -J706- and the seat occupied recognition pressure sensor -G452-.
The passive occupant detection system is only installed on the front passenger seat.
Removing
-- Disconnect battery ground cable. Refer to [For transmission(s) 02E] [For engine(s) CBRA, BPY, CETA, CCTA, CEPB, CDMA] Removal and Installation .
-- Remove passenger seat:
- Manually Adjustable Front Seat, Removing and Installing, refer to FRONT SEAT
- Power Front Seat, Removing and Installing, refer to FRONT SEAT
-- Attach the front seat to the fixture for seat repair VAS 6136. Refer to INSTALLING FRONT SEAT ON VAS 6136 .
-- Remove backrest:
- Manually Adjustable Front Backrest, Removing and Installing, refer to FRONT BACKREST
- Power Front Backrest, Removing and Installing, refer to FRONT BACKREST
Service Kit, Removing
-- Disconnect the connector -6-.
-- Remove bolts -2- (quantity: 2)
-- Remove cover with upholstery from seat pan. Refer to SEAT PAN COVER AND UPHOLSTERY .
-- Open the guide clip -8-.
Connectors -3- and -7- must not be separated.
-- Slide Seat Occupied Recognition Pressure Sensor -G452- -4- sideways from clip -9-.
-- Fold the cushion -5- upward.
The cushion is included as part of the service kit.
Clip -4- must not be separated.
The hard foam insert in the crease is not included in the service kit.
-- Remove clips -2- and -3- (quantity: 2).
-- Carefully pull seat occupied recognition mat -1- with upholstery -5- upward while guiding Seat Occupied Recognition Pressure Sensor -G452- and Seat Occupied Recognition Control Module -J706- through seat pan without disconnecting connectors.
The pressure hose and the Seat Occupied Recognition Mat -1- must not be kinked under any circumstances during repairs.
-- Remove the complete service kit.
Installation
- Follow all safety precautions when working on pyrotechnic components. Refer to RESTRAINT SYSTEM COMPONENTS, SAFETY PRECAUTIONS AND TESTING PROCEDURES .
- Before handling pyrotechnical components (for example, connecting electrical connector), the person handling them must "discharge static electricity". For example, by briefly touching the door striker pin.
Service kit, installing
The hard foam insert in the cover is not part of the service kit. Reuse the insert that is already in the seat cover.
-- Guide Seat Occupied Recognition Pressure Sensor -G452- and Seat Occupied Recognition Control Module -J706- from above through seat pan without disconnecting connectors.
The pressure hose and the Seat Occupied Recognition Mat -1- must not be kinked under any circumstances during repairs.
-- Pull the cover between the seat pan and passenger occupant detection system mat -1- so that it is smooth and free of creases.
-- Secure the Seat Occupied Recognition Mat -1- with the clips -2- and -3- (quantity: 2).
-- Secure Seat Occupied Recognition Pressure Sensor -G452- -4-.
-- Tighten Seat Occupied Recognition Control Module -J706- with bolts -2- (quantity: 2).
-- Connect connector -6-.
-- Install cover with upholstery on seat pan. Refer to SEAT PAN COVER AND UPHOLSTERY .
Further installation is performed in the reverse order of removal.
Make sure the connectors are installed all the way in and are secure.
-- Switch on ignition.
Connect the battery with the ignition switched on. Pyrotechnic components could deploy after connecting the battery if they were not repaired correctly. Individuals must not be inside the vehicle when connecting the battery.
-- Connect battery ground cable with ignition switched on. Refer to [For transmission(s) 02E] [For engine(s) CBRA, BPY, CETA, CCTA, CEPB, CDMA] Removal and Installation .
-- If Airbag Malfunction Indicator Lamp (MIL) -K75- indicates a fault after installation, DTC memory must be checked, deleted and checked again => .
-- When installing a new service kit, the following program should be run under "Airbag" in guided fault finding after installing the passenger's seat:
- Seat Occupied Recognition Control Module -J706- basic setting
