SIDE - SECOND ROW SEATING Chrysler Town & Country V рестайлинг

SIDE - SECOND ROW SEATING

The acceleration-type second row seating side impact sensors are electronic accelerometers that sense the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. Each sensor also contains an electronic communication chip that allows the unit to communicate the sensor status as well as sensor fault information to the microcontroller within the Occupant Restraint Controller (ORC).

The ORC microcontroller continuously monitors all of the side passive restraint system electrical circuits to determine the system readiness. If the ORC detects a monitored system fault, it sets a Diagnostic Trouble Code (DTC) and controls the airbag indicator operation accordingly. The impact sensors each receive battery current and ground through the dedicated left and right sensor plus and minus circuits from the ORC. The impact sensors and the ORC communicate by modulating the voltage in the sensor plus circuit.

The hard wired circuits between the acceleration-type second row seating side impact sensors and the ORC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the impact sensors or the electronic controls and communication between other modules and devices that provide features of the Supplemental Restraint System (SRS). The most reliable, efficient and accurate means to diagnose the impact sensors or the electronic controls and communication related to acceleration-type second row seating side impact sensor operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

The acceleration-type third row seating side impact sensors are electronic accelerometers that sense the rate of vehicle deceleration, which provides verification of the direction and severity of an impact.

Scheme 101

An Occupant Detection Sensor (ODS) is located below the passenger side front seat cushion trim cover. This sensor provides information to the Occupant Restraint Controller (ORC) used for control of the passenger belt alert feature.

The ODS consists of a flexible clear plastic mat (1) containing several resistive membrane, force sensing resistor cells. In vehicles with a molded in place seat trim cover, the sensor is actually enclosed within a heat staked film envelope or pocket that is then molded into the seat cushion foam. In vehicles with a cut and sewn seat trim cover, the sensor is secured by two adhesive patches (2) to the seat cushion foam. In cut and sewn seats with an optional seat heater, the heater mat is secured with adhesive over the top of the seat cushion foam with the sensor sandwiched between the heater mat and the cushion foam.

A short, two-conductor pigtail wire and connector (4) connect the sensor to the vehicle electrical system through a dedicated take out and connector of the seat wire harness. A hot melt adhesive block (3) encapsulates and protects the connections between the electrical conductors in the tail of the sensor mat and the pigtail wires as well as a diagnostic resistor.

The ODS cannot be adjusted or repaired, and must be replaced if damaged or ineffective. In seats with a molded in place trim cover, the ODS can only be serviced by replacing the entire seat cushion foam and trim assembly. In seats with a cut and sewn trim cover and a heater mat, the ODS can only be serviced by replacing the entire seat cushion foam, ODS and heater mat unit. In seats with a cut and sewn trim cover and no heater mat, the ODS is available for individual service replacement.

The Occupant Detection Sensor (ODS) acts as a simple switch to detect loads placed upon the passenger side front seat cushion. The sensor circuits are connected to and monitored by the Occupant Restraint Controller (ORC) whenever the ignition switch is in the ON position. The ORC uses an algorithm logic in monitoring the changing states of the sensor input to determine whether the seat cushion load is static or dynamic.

The ORC microcontroller continuously monitors all of the Supplemental Restraint System (SRS) electrical circuits to determine the system status and readiness. If the ORC detects a monitored system fault, it sets a Diagnostic Trouble Code (DTC). However, because the ODS input is only used for control of the passenger belt alert feature, which has no effect on SRS component features or functions, the airbag indicator is NOT illuminated in response to a detected ODS circuit fault.

The ODS receives source current and a clean ground through dedicated sensor plus and minus circuits from the ORC. The ORC then sends the appropriate sensor status information to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), which uses this information as an additional logic input for control of the seat belt indicator and the passenger belt alert feature.

The hard wired circuits between the ODS and the ORC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the ODS or the electronic controls and communication between other modules and devices that provide some features of the passenger belt alert feature. The most reliable, efficient and accurate means to diagnose the ODS or the electronic controls and communication related to the passenger belt alert feature operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

In seats with a molded in place trim cover, the ODS can only be serviced by replacing the entire seat cushion foam and trim assembly. In seats with a cut and sewn trim cover and a heater mat, the ODS can only be serviced by replacing the entire seat cushion foam, ODS and heater mat unit.

1. Mark the Center Line (CL) of the seat cushion on the top of the seat cushion foam.
2. Measure and mark a transverse line (Distance A) on the top of the seat cushion foam 119 millimeters (4.68 inches) rearward from the back edge of the front crimp channel in the seat cushion foam (4). CAUTION: The adhesive used to secure the ODS to the seat is heat activated and requires that both the adhesive and the material it is applied to be ideally between 21° and 38° C (between 70° and 100° F). Application of the ODS to surfaces below 10° C (50° F) is not recommended as the adhesive becomes too firm to readily adhere. Do not touch or allow the adhesive patches to contact any foreign materials with the release paper removed. Do not attempt to add adhesive materials to the ODS.
3. Peel the release paper off of the front adhesive patch (2) on the underside of the Occupant Detection Sensor mat (1).

The Seat Track Position Sensor (STPS) (2) is a Hall Effect-type sensor used on some vehicles. This sensor consists of a Hall Effect Integrated Circuit (IC) chip encased in potting material within a cavity of the molded plastic sensor housing.

The STPS housing has a mounting slot containing an integral latch feature (1) and slides and latches onto a stamped metal blade-type bracket located on the inboard side of the upper inboard seat adjuster track near the rear of both the passenger and driver front seats. A molded connector receptacle (3) integral to the STPS housing is connected to the vehicle electrical system through a connector and take out of the seat wire harness beneath the front seat cushion frame.

The STPS cannot be adjusted or repaired and, if ineffective or damaged, the entire STPS unit must be replaced.

The Seat Track Position Sensor (STPS) is designed to provide a seat position data input to the Occupant Restraint Controller (ORC) indicating whether the driver or passenger front seat is in a full forward or a not full forward position. The ORC uses this data as an additional logic input for use in determining the appropriate deployment force to be used when deploying the multistage Driver AirBag (DAB) or Passenger AirBag (PAB).

The STPS receives a nominal five volt supply from the ORC. The STPS communicates the seat position by modulating the voltage returned to the ORC on a sensor data circuit. The ORC also monitors the condition of the STPS circuits and will store a Diagnostic Trouble Code (DTC) for any fault that is detected. The ORC sends messages over the CAN data bus to control the illumination of the airbag indicator in the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN).

The hard wired circuits between the STPS and the ORC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the STPS or the electronic controls and communication between other modules and devices that provide features of the Supplemental Restraint System (SRS). The most reliable, efficient and accurate means to diagnose the STPS or the electronic controls and communication related to STPS operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
