5 SUPPLEMENTL RESTRINT SYSTEM IRBG SYSTEM 5 SYSTEM DESCRIPTION 1. DESCRIPTION OF SUPPLEMENTL RESTRINT SYSTEM (S) General description (1) In this system, the center airbag sensor installed on the floor under the /C unit determines whether or not to activate the S airbags and seat belt pretensioners by receiving the collision signal from the airbag sensors (excluding the center airbag sensor). When there is trouble in the system, the center airbag sensor turns on the S warning light on the combination meter to inform the driver. Description of the dual stage control (1) The center airbag sensor controls the dual stage deployment of the driver airbag in the horn button and the passenger airbag on the instrument panel. The center airbag sensor controls the dual stage deployment of the driver airbag according to the collision impact, seat position and seat belt ON/OFF state. It also controls the dual stage deployment of the passenger airbag according to the collision impact. Description of check mode (signal check) (1) This center airbag sensor can be operated using the check mode of the intelligent tester function. Check mode can detect and output DTC by using the intelligent tester to switch the center airbag sensor to the check mode. simulation method should be used if the malfunction cannot be reproduced during troubleshooting (the malfunction is temporarily solved, etc.). In this case, joggling each connector, or driving on a city or rough road with the center airbag sensor in check mode makes it possible to obtain a more accurate malfunction condition. 2. IGNITION JUDGMENT ND CONDITIONS Operation in case of front collision (1) When the vehicle collides in the hatched area (Fig. 1) and shock is larger than a predetermined level, the airbags (driver and front passenger) are activated automatically. The deceleration sensor of the center airbag sensor determines the need for ignition in response to collisions within the hatched area based on the signal from the deceleration sensor of the front airbag sensor.

13 SUPPLEMENTL RESTRINT SYSTEM IRBG SYSTEM 13 DIGNOSIS SYSTEM CG SG SIL 1. CHECK DLC3 The ECU uses ISO for communication. The terminal arrangement of the DLC3 complies with SE J1962 and matches the ISO format. BT H100769E98 Symbols (Terminal No.) Terminal Description Condition Specified Condition SIL (7) - SG (5) During transmission During Transmission Pulse generation CG (4) - Body ground Chassis ground lways Below 1 Ω SG (5) - Body ground Signal ground lways Below 1 Ω BT (16) - Body ground Battery positive lways lways 10 to 14 V If the display shows UNBLE TO CONNECT TO VEHICLE when you connect the cable of the intelligent tester to the DLC3, turn the ignition switch to the ON position and operate the intelligent tester, there is a problem on the vehicle side or tester side. If communication is normal when the tester is connected to another vehicle, inspect the DLC3 on the original vehicle. If communication is still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself. Consult the Service Department listed in the tester's instruction manual. 2. SYMPTOM SIMULTION The most difficult case in troubleshooting is when no symptoms occur. In such cases, a thorough customer problem analysis must be carried out. Then the same or similar conditions and environment in which the problem occurred in the customer's vehicle should be simulated. No matter how experienced or skilled a technician may be, if he proceeds to troubleshooting without confirming the problem symptoms, he will likely overlook something important and make a wrong guess at some points in the repair operation. This leads to a standstill in troubleshooting.

14 14 SUPPLEMENTL RESTRINT SYSTEM IRBG SYSTEM Shake Slightly Vibrate Slightly Vibrate Slightly D100465E01 Vibration method: When vibration seems to be the major cause. Perform the simulation method only during the primary check period (for approximately 6 seconds after the ignition switch is turned to the ON position). (1) Slightly vibrate the part of the sensor considered to be the problem cause with your fingers and check whether the malfunction occurs. Shaking the relays too strongly may result in open relays. (2) Slightly shake the connector vertically and horizontally. (3) Slightly shake the wire harness vertically and horizontally. The connector joint and fulcrum of the vibration are the major areas to be checked thoroughly. 3. FUNCTION OF S WRNI LIGHT Primary check (1) Wait for at least 2 seconds, and then turn the ignition switch to the ON position. The S warning light comes on for approximately 6 seconds and the S airbag system diagnosis (including the seat belt pretensioner and occupant classification system) is performed. If trouble is detected during the primary check, the S warning light remains on even after the primary check period (for approximately 6 seconds) has elapsed. Constant check (1) fter the primary check, the center airbag sensor constantly monitors the S airbag system for trouble. If trouble is detected during the constant check, the center airbag sensor functions as follows: The S warning light comes on. The S warning light go off, and then comes on. This blinking pattern indicates the source voltage drop. The S warning light goes off 10 seconds after the source voltage returns to normal. Review (1) When the airbag system is normal: The S warning light comes on only during the primary check period (for approximately 6 seconds after the ignition switch is turned to the ON position). (2) When the airbag system has trouble: The S warning light remains on even after the primary check period has elapsed.

15 SUPPLEMENTL RESTRINT SYSTEM IRBG SYSTEM 15 C093955E03 The S warning light goes off after the primary check, but comes on again during the constant check. The S warning light does not come on when turning the ignition switch from the LOCK to ON position. The center airbag sensor keeps the S warning light on if the airbag has been deployed. 4. S WRNI LIGHT CHECK Turn the ignition switch to the ON position, and check that the S warning light comes on for approximately 6 seconds (primary check). Check that the S warning light goes off approximately 6 seconds after the ignition switch is turned to the ON position (constant check). When any of the following symptoms occur, refer to "Problem Symptoms Table" (See page -9). The S warning light comes on occasionally after the primary check period has elapsed. The S warning light comes on, but DTC is not output. The ignition switch is turned from the LOCK to ON position, but the S warning light does not come on. 5. FUNCTION OF PSSEER IRBG ON/OFF INDICTOR Initial check (1) Turn the ignition switch to the ON position. (2) The passenger airbag ON/OFF indicator comes on for approximately 4 seconds, then goes off for approximately 2 seconds. (3) pproximately 6 seconds after the ignition switch is turned ON, the passenger airbag ON/ OFF indicator will be ON or OFF depending on the conditions listed below. Passenger airbag ON/ OFF indicator Condition "ON" indicator "OFF" indicator S warning light Vacant OFF OFF OFF dult is seated. ON OFF OFF Child is seated. OFF ON OFF Child restraint system is set. OFF ON OFF Front passenger occupant classification failure OFF ON ON The passenger airbag ON/OFF indicator is based on the timing chart below in order to check the indicator light circuit.

16 16 SUPPLEMENTL RESTRINT SYSTEM IRBG SYSTEM When the front passenger occupant classification system has trouble, both the S warning light and the passenger airbag ON/OFF indicator ("OFF") come on. In this case, check the DTCs in "IRBG SYSTEM" first. Then troubleshoot the occupant classification system if DTC B1650/32 is detected, and troubleshoot the passenger airbag ON/OFF indicator if DTC B1660/43 is detected. Ignition Switch ON OFF 4 sec. 2 sec. Passenger irbag ON/OFF Indicator ( ON ) ON OFF 4 sec. 2 sec. Passenger irbag ON/OFF Indicator ( OFF ) ON OFF ON/OFF condition depends on the front passenger detection results. C123768E01 C PSSEER IRBG ON/OFF INDICTOR CHECK Turn the ignition switch to the ON position. Check that the passenger airbag ON/OFF indicator ("ON" and "OFF") comes on for approximately 4 seconds, then goes off for approximately 2 seconds. Refer to the table in the previous step regarding the passenger airbag ON/OFF indicator when the ignition switch is turned to the ON position and approximately 6 seconds pass. 7. RELESE METHOD OF CTIVTION PREVENTION MECHNISM The activation prevention mechanism is built into the connector for the squib circuit of the S. s explained in the troubleshooting section, insert a piece of paper that is the same thickness as the male terminal between the terminal and the short spring to release it (Refer to the illustration below). CUTION: Never release the activation prevention mechanism on the squib connector even when inspection with the squib disconnected.

26 26 SUPPLEMENTL RESTRINT SYSTEM IRBG SYSTEM IRBG SYSTEM DIGNOSTIC TROUBLE CODE CHRT If a trouble code is displayed during the DTC check, check the circuit listed for the code in the table below (refer to the appropriate page). When the S warning light remains on and the DTC output is the normal system code, a voltage source drop is likely occurring. This malfunction is not stored in the memory by the center airbag sensor assembly. If the power source voltage returns to normal, the S warning light will automatically go off. When 2 or more codes are indicated, the code with the lower number appears first. If a code is not listed on the display chart, the center airbag sensor assembly may have failed. In the case of any malfunction concerning an open circuit, short to ground, short to B+, or squib malfunction, other trouble codes may not be detected. In this case, repair the malfunction currently indicated and then reinspect the system. Mark in the check mode column: *1: DTC is not corresponding to the check mode. *2: DTC is corresponding to the check mode. DTC which has the mark of the *3 is output only the equipped car of side and curtain shield airbag.

DESCRIPTION OF OCCUPNT CLSSIFICTION SYSTEM GENERL DESCRIPTION (1) In the occupant classification system, the occupant classification ECU calculates the weight of the occupant based on a signal from the occupant classification sensors. This system recognizes the occupant as a child if it detects a weight of less than 36 kg (79.37 lb), and disables the front passenger airbag and front passenger side - side airbag. (2) This system is mainly comprised of 4 occupant classification sensors that detect the load on the front passenger seat. The occupant classification ECU controls the system, and the passenger airbag ON/OFF indicator indicates the ON/OFF condition of the front passenger airbag and front passenger side - side airbag.

SYMPTOM SIMULTION The most difficult case in troubleshooting is when no symptoms occur. In such cases, a thorough customer problem analysis must be carried out. Then the same or similar conditions and environment in which the problem occurred in the customer's vehicle should be simulated. No matter how experienced or skilled a technician may be, if he proceeds to troubleshooting without confirming the problem symptoms, he will likely overlook something important and make a wrong guess at some points in the repair operation. This leads to a standstill in troubleshooting. Vibration method: When vibration seems to be the major cause. Perform the simulation method only during the primary check period (for approximately 6 seconds after the ignition switch is turned to the ON position. (1) Slightly vibrate the part of the sensor considered to be the problem cause with your fingers and check whether the malfunction occurs. Shaking the relays too strongly may result in open relays. (2) Slightly shake the connector vertically and horizontally. (3) Slightly shake the wire harness vertically and horizontally. The connector joint and fulcrum of the vibration are the major areas to be checked thoroughly. Simulation method for DTC B1794: Turn the ignition switch from the LOCK to the ON position, hold it for 10 seconds, and back to off again 50 times in a row. DTC B1794 is output if the occupant classification ECU receives the ignition switch LOCK-ON-LOCK signal 50 times in a row when a malfunction occurs in the power circuit for the occupant classification system. 3.
