Supplemental Inflatable Restraint System Ford Crown Victoria II

DESCRIPTION & OPERATION

The Supplemental Restraint System (SRS), also known as air bag system, is designed to provide increased accident protection for driver and passenger by deploying air bags in a front-end or side (lateral) collision. The air bags, stored in center of steering wheel, in instrument panel above glove box and instrument panel above glove box and in driver"s and passenger"s front seat back, deploy in about 40 milliseconds after crash sensors close. Air bag system is designed to be used with 3-point seat belts.

During a front-end collision, the air bag Restraints Control Module (RCM), using input from front impact crash sensor, discriminates between an event that warrants air bag and seat belt pretensioner deployment and an event that does not. Using inputs from passenger seat occupant classification sensor, if equipped, driver seat track position sensor and seat belt switches in conjunction with front impact crash sensor inputs, RCM determines which air bags to deploy and at what deployment rate. In a crash of sufficient force, the RCM signals the air bag modules and seat belt pretensioners to simultaneously deploy.

During a side or lateral collision, the RCM, using inputs from right and/or left side crash sensor, discriminates between an event that warrants air bag deployment and an event that does not. In a collision of sufficient force, the RCM signals the right and/or left seat air bag module(s) to deploy.

Air bag system includes the following components: Restraints Control Module (RCM) or also known as air bag monitor, safing sensor (located inside the RCM), back-up power supply (also located inside the RCM), dual-stage driver-side air bag module, dual-stage passenger-side air bag module, driver and passenger seat belt pretensioners and seat belt switches, driver seat track position sensor, passenger seat occupant classification sensor, if equipped, right- and left-side air bag modules and crash sensors, if equipped, AIR BAG warning light, front crash sensor, ignitor assemblies (located in air bag modules), clockspring and associated wiring harnesses.

SYSTEM OPERATION CHECK

1. When checking air bag system operation (also known as prove out system), and upon completion of each diagnostic test, check for faults in air bag system. To check system, turn ignition switch to RUN position. If AIR BAG warning light illuminates for 6 seconds and then goes out, air bag system is functioning properly and no faults exist.
2. If a fault is detected in air bag system during initial system check, AIR BAG warning light will flash a code sequence, indicating a fault in system. Count number of flashes after fault code has cycled twice. Number of flashes represents a code number used to diagnose air bag system. See «DIAGNOSTICS»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__diagnostics) . If AIR BAG warning light either fails to light or stays on continuously, go to «DIAGNOSTIC SYMPTOMS»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) table.
3. If a system fault exists and AIR BAG warning light fails to light, an audible tone will be heard, indicating AIR BAG warning light is out and service is required.

AIR BAG SAFETY PRECAUTIONS

Observed these precautions when servicing the air bag system

1. Disable air bag system before servicing any air bag system, steering column or instrument panel components. Failure to do so may result in accidental air bag deployment and personal injury. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__disabling-activating-air-bag-system) .
2. Wait one minute after disabling air bag system before working on vehicle. Back-up power supply holds a deployment charge for about one minute after battery is disconnected. Servicing air bag system before one minute may cause accidental air bag deployment and possible personal injury.
3. Because driver-side and passenger-side front air bags each have 2 deployment stages, it is possible that one stage has deployed, but not the other. If a front air bag module has deployed, in is mandatory that the module be remotely deployed prior to disposal. See «DISPOSAL PROCEDURES»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__disposal-procedures) .
4. Because of critical system operating requirements, DO NOT dissemble or attempt to repair crash sensors, clockspring, restraints control module, seat belt pretensioner or air bag modules. Repairs are made by replacement only.
5. Always wear safety glasses whenever servicing an air bag equipped vehicle or handling an air bag.
6. When carrying a live air bag module, ensure air bag module and trim cover are pointed away from your body. This minimizes chance of injury in event of an accidental deployment.
7. When placing a live air bag module on a bench or other surface, always face air bag module and trim cover facing up and away from surface. This will reduce motion of module if it is accidentally deployed.
8. After deployment, air bag surface may contain deposits of sodium hydroxide, which may irritate skin. Sodium hydroxide is a product of gas generant combustion. Always wear gloves and safety glasses when handling a deployed air bag. Wash your hands using mild soap and water. Follow correct disposal procedures. See «DISPOSAL PROCEDURES»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__disposal-procedures) .
9. If scrapping a vehicle with an undeployed air bag module, air bag must be deployed. See «DISPOSAL PROCEDURES»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__disposal-procedures) .
10. If a part is replaced and NEW part does not correct condition, reinstall original part and perform diagnostic procedure again.
11. Never probe connectors on air bag module. Doing so may cause air bag deployment and/or personal injury.
12. Instruction to disconnect always refers to connector. DO NOT remove component from vehicle if instructed to disconnect.
13. After any servicing, ensure AIR BAG warning light does not indicate any fault codes. See «SYSTEM OPERATION CHECK»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__system-operation-check) .
14. Replace air bag module if trim cover (deployment door) is marred or damaged. DO NOT repaint trim cover. Paint may degrade cover material. Replace air bag module as necessary. See «SCRAPPED VEHICLE»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__scrapped-vehicle-seats-installed) under DISPOSAL PROCEDURES.
15. If vehicle is involved in collision in which center tunnel area is damaged, inspect RCM mounting bracket for deformation. If damaged, RCM must be replaced whether or not air bags have deployed. Additionally, ensure RCM mounting area is restored to its original condition.

DIAGNOSTICS

Note. Unless otherwise specified, New Generation STAR (NGS) tester (418-F052), Worldwide Diagnostic System (WDS) tester (418- F224), or equivalent tester will be referred to as scan tool.

SELF-DIAGNOSTICS

During vehicle operation, the Restraints Control Module (RCM) detects and stores both intermittent and hard failure codes in non-volatile memory. The RCM will also display a 2-digit Light Flash Code (LFC) on the AIR BAG warning light. For example, a fault Code 32 will be displayed in following manner: Flash-flash-flash, one-second pause, flash-flash, 3-second pause. Cycle will repeat.

Diagnostic Trouble Codes (DTCs) can be retrieved with the New Generation Star (NGS) tester, Worldwide Diagnostic System (WDS) tester or equivalent scan tool, using the retrieve/clear continuous codes option. If no DTCs are present, scan tool tester will display SYSTEM PASSED message. Once a fault code is logged in RCM memory, it will stay in memory until 254 ignition cycles have been recorded or until scan tool is used to erase the DTCs.

The on-demand self-test can be used to verify there are no electrical faults within air bag system. During this test RCM will check each electrical component in system. If fault is detected, DTC is displayed on scan tool with brief description of fault. Faults detected during self-test are not stored in memory, unless same fault was detected during normal vehicle operation. Self-test should be run after service to verify operation.

Coded fault feature is prioritized so that if 2 or more different faults occur at same time, highest priority fault indication will be shown until corrected using appropriate diagnostic test procedure.

If a system fault exists and AIR BAG warning light is malfunctioning, a series of 5 sets of 5 beeps will sound, indicating service is needed. Number of beeps does not indicate a fault code.

DIAGNOSTIC PROCEDURE

1. Retrieve all DTCs stored in RCM memory by executing RETRIEVE/CLEAR CONTINUOUS DTCs. See «RETRIEVING FAULT CODES»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__retrieving-fault-codes) .
2. Run on-demand self-test to determine what DTCs are currently being sensed by RCM. See «ON-DEMAND SELF-TEST»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__on-demand-self-test) .
3. If stored DTCs are different than current DTCs, always repair current DTCs first.
4. If different continuous DTCs are displayed from memory than on-demand self-test, repair on-demand self-test codes first then repair continuous codes.
5. If no DTCs are retrieved and symptoms are observed, refer to diagnostic symptoms table. See «DIAGNOSTIC SYMPTOMS»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) table.

INSPECTION & VERIFICATION

1. If AIR BAG warning light is ON, visually inspect for obvious mechanical and electrical damage of following components prior to performing diagnostic tests: Damaged bracket on restraints control module or front crash sensor. Blown fuse(s). Damaged wiring harness. Loose or corroded connectors. Damaged shorting bars. Open or short circuits or loosely mounted sensors. If damage is not visually evident, use scan tool to retrieve Diagnostic Trouble Codes (DTCs) and perform on-demand self-test. See «USING SCAN TOOL»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__using-scan-tool) .

USING SCAN TOOL

1. Connect scan tool to Data Link Connector (DLC), located under instrument panel, to retrieve continuous diagnostic trouble codes (DTCs) and run self-test diagnostics.
2. If self-test is passed and no DTCs are retrieved, go to diagnostic symptoms table. See «DIAGNOSTIC SYMPTOMS»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) table.
3. If DTCs are retrieved, go to diagnostic trouble code identification table to continue diagnostics. See «DIAGNOSTIC TROUBLE CODE IDENTIFICATION»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) table.
4. If RCM cannot be accessed by scan tool, go to «TEST Y: NO COMMUNICATION WITH RCM»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__test-y-no-communication-with-rcm) under «DIAGNOSTIC TESTS»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) to continue diagnostics.

RETRIEVING FAULT CODES

Connect scan tool to Data Link Connector (DLC), located under left-side of instrument panel. Turn ignition switch to RUN position. Follow manufacturer's instructions for scan tool being used. All continuous DTCs will be displayed on scan tool screen. Record DTCs displayed for reference. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION table. When DTCs are cleared, they cannot be retrieved.

CLEARING FAULT CODES

1. Connect scan tool to Data Link Connector (DLC), located under left-side of instrument panel. Turn ignition switch to RUN position. Follow manufacturer's instructions for scan tool being used.
2. The scan tool will retrieve DTCs again after clearing DTCs, and if any remain they will be displayed. Hard DTCs will be re-displayed after clearing DTCs since they cannot be cleared from RCM memory.

ON-DEMAND SELF-TEST

Connect scan tool to Data Link Connector (DLC), located under left-side of instrument panel. Turn ignition switch to RUN position. Follow manufacturer's instructions for scan tool being used. Restraints Control Module (RCM) will run on-demand self-test and display on-demand DTCs on tester screen.

BIT-MAPPED DIAGNOSTIC TROUBLE CODES

Many of the continuous on-demand Diagnostic Trouble Codes (DTCs) that can be present in Restraints Control Module (RCM) are bit-mapped DTCs that utilize Parameter Identifications (PIDs), also known as flagged faults. Bit-mapped DTCs are conceptually different from the previous style of DTCs.

Previously, DTCs identified a specific concern for a given component and pointed to a particular diagnostic path. In the diagnostic path, PIDs are sometimes used to determine the root cause. Bit-mapped DTCs DO NOT identify the specific concern. A bit-mapped DTC identifies the component(s) in which the concern exists. The next level (PIDs or flagged faults) identifies the specific concern.

A scan tool must be used to view PIDs (flagged faults) of a bit-mapped DTC. Once a scan tool has retrieved a bit-mapped DTC, the scan tool will provide the option to flag that DTC. When the option to flag the DTC is available, it must be carried out to identify the specific concern that is present. When the flag option has been carried out, the scan tool will then display the PIDs for that DTC, including the status or state that exists (on-demand DTC) or existed (continuous DTC).

To view and flag bit-mapped DTCs, follow the following steps

1. Connect scan tool to Data Link Connector (DLC), located under left-side of instrument panel.
2. Turn ignition switch to RUN position.
3. Follow manufacturer's instructions for the scan tool being used.
4. Perform on-demand self-test or retrieve continuous DTCs.
5. Select DTC and the FLAG option on scan tool. Scan tool will now display PIDs related to the DTC. Record all flagged faults.

PID/DATA MONITOR & RECORD

PID/Data Monitor and Record option allows technician to read the state of several Parameter IDs (PIDs) to aid in diagnosing the system. To retrieve PIDs, connect scan tool to Data Link Connector (DLC), located under instrument panel, and follow scan tool manufacturer"s instructions. PIDs are updated continuously on scan tool display.

Principles Of Operation

RCM must be programmed as part of the repair procedure. If this procedure is not followed, the RCM will not function correctly and may set a number of Diagnostic Trouble Codes (DTCs), including DTC B2477, which indicates that necessary data has not been programmed into the RCM.

Modules that need to be programmed should not be exchanged between vehicles. In most cases the parameter values or settings are unique to that vehicle, and if not set correctly, will cause concerns or faults.

If the RCM and Powertrain Control Module (PCM) do not contain the correct information, the scan tool will either request "As Built" data or display a list of items that will be required to manually configure. The scan tool will program the RCM based on the data that is entered.

It is not longer necessary to command the scan tool to gather module option content from the old module. The scan tool automatically obtains any available module option content from the old module during the vehicle identification routine that runs when the scan tool is initially connected to the vehicle. It is important that you connect the scan tool to the vehicle and obtain configuration data prior to removing module.

ZERO OCCUPANT CLASSIFICATION SENSOR (OCS)

Ensure front passenger seat is empty. Connect scan tool to Data Link Connector (DLC). See USING SCAN TOOL . Use scan tool to trigger active command and zero OCS. If scan tool is not available, zeroing will occur during normal driving conditions. Perform system operation check. See SYSTEM OPERATION CHECK .

Restraints Control Module (RCM) monitors seat track position switch circuits for faults. If RCM detects a short to battery, it will store Diagnostic Trouble Code (DTC) C1982 in memory and flash Code 49 on AIR BAG warning light.

A seat track position sensor short to battery circuit fault could be caused by damaged wiring, terminals or connectors or a faulty RCM.

1. Check for hard or intermittent DTC Turn ignition switch to OFF position. Connect scan tool to Data Link Connector (DLC). See «USING SCAN TOOL»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__using-scan-tool) under DIAGNOSTICS. Turn ignition switch to RUN position. Retrieve and record any continuous DTCs. See «RETRIEVING FAULT CODES»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__retrieving-fault-codes) under DIAGNOSTICS. Perform on-demand self-test. See «ON-DEMAND SELF-TEST»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__on-demand-self-test) under DIAGNOSTICS. If DTC C1982 was retrieved during on-demand self-test, fault is hard. Go to next step. If DTC C1982 was not retrieved, fault is intermittent. Go to step 5.
2. Check circuit for short to battery between left front seat & RCM Turn ignition switch to OFF position. Disable air bag system. See «DISABLING SYSTEM»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__disabling-system) under DISABLING & ACTIVATING AIR BAG SYSTEM. Access RCM and disconnect connector C310A. See «RESTRAINTS CONTROL MODULE (RCM)»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) under REMOVAL & INSTALLATION. Disconnect left front seat floor connector C311. Turn ignition switch to RUN position. Measure voltage between ground and vehicle harness side of left front seat floor connector C311, terminal No. 5 (Light Green wire, circuit No. 1520). (Scheme 69) Measure voltage between ground and vehicle harness side of left front seat floor connector C311, terminal No. 4 (Tan/Black wire, circuit No. 1558). If voltage is less than 0.2 volt in both circuits, go to next step. If voltage is more than 0.2 volt in either circuit, repair short to battery in appropriate wire. See «WIRING DIAGRAMS»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system). Go to step 6.
3. Check circuit for short to battery in left front seat Turn ignition switch to OFF position. Reconnect left front seat floor connector C311. Disconnect seat track position sensor connector. Turn ignition switch to RUN position. Measure voltage in Light Green wire between ground and harness side of seat track position sensor connector. Measure voltage in Tan/Black wire between ground and harness side of seat track position sensor connector. If voltage is less than 0.2 volt in both circuits, go to next step. If voltage is more than 0.2 volt in either circuit, repair short to battery in appropriate wire. Go to step 6. NOTE: Ensure all air bag system simulators, sensor electrical connectors and RCM electrical connectors are connected prior to carrying out on-demand self-test or erroneous faults may be set.
4. Confirm RCM fault Turn ignition switch to OFF position. Reconnect RCM connector C310A. Turn ignition switch to RUN position. Perform on-demand self-test. If DTC C1982 was retrieved during on-demand self-test, replace RCM. Go to step 6. If DTC C1982 was not retrieved during on-demand self-test, fault is corrected. Go to step 6.
5. Check for intermittent fault Turn ignition switch to OFF position. Disable air bag system. See «DISABLING SYSTEM»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__disabling-system) under DISABLING & ACTIVATING AIR BAG SYSTEM. Perform on-demand self-test. If DTC C1982 was retrieved during on-demand self-test, go to step 2. If DTC C1982 was not retrieved during on-demand self-test, check for cause of intermittent fault. Attempt to recreate fault by flexing wire harness and cycling ignition switch frequently. Repair any intermittent problems found. Go to next step.
6. Check for additional DTCs Refer to continuous DTCs recorded in step 1. If any continuous DTCs were retrieved, go to diagnostic trouble code identification table for direction to appropriate test. See «DIAGNOSTIC TROUBLE CODE IDENTIFICATION»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) table. DO NOT clear any DTCs until all DTCs have been resolved. If no DTCs were retrieved, reconnect air bag system. Activate air bag system. See «ACTIVATING SYSTEM»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system) under DISABLING & ACTIVATING AIR BAG SYSTEM. Clear all DTCs. See «CLEARING FAULT CODES»(/ford/crown-victoria/ii-1997-2011/remont/airbag/#supplemental-inflatable-restraint-system__clearing-fault-codes) under DIAGNOSTICS.

TEST Y: NO COMMUNICATION WITH RCM

Note. Before proceeding, see AIR BAG SAFETY PRECAUTIONS .
