Wait at least one minute after disconnecting the battery ground cable. Failure to follow this instruction may result in personal injury. NOTE:Following the pinpoint tests when a diagnostic trouble code (DTC) is not present, or the air bag warning lamp is not permanently illuminated, will result in needless replacement of air bag system components and repeat repairs. Speak with the customer to determine if a particular set of conditions must be met in order for a fault to occur. If an illuminated air bag warning lamp is reported by the customer but is not present when the vehicle comes in for repair, pinpoint test diagnostics cannot be used. Diagnosing Customer Concerns with Hard DTCs WARNING:Do not use substitute air bag simulators when working on the SRS. Use only the appropriate tool. Failure to follow this instruction may result in personal injury. Most air bag system diagnostic procedures require the use of system deactivation and system reactivation procedures. These procedures require the air bag module(s) and safety belt buckle pretensioners to be disconnected from the SRS, thereby removing the risk of air bag deployment while diagnostics are carried out. Air bag simulators are required to carry out diagnosis and testing of the air bag system. The simulator contains a resistor, used to simulate an air bag module connection to the system. It is not acceptable to short-circuit the air bag module connections with a 0 ohm jumper wire. If a 0 ohm jumper wire is used to short-circuit the air bag module connections, an illuminated air bag warning lamp will be displayed and a DTC logged by the restraints control module (RCM). Deactivation WARNING:The back up power supply must be depleted, before any work is carried out on the SRS. Wait at least one minute after disconnecting the battery ground cable. Failure to follow this instruction may result in personal injury. - Disconnect the battery ground cable.
REFER to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures). - Wait 1 minute for the backup power supply in the RCM to deplete its stored energy.

Glossary Air Bag Simulator Air bag simulators are used to simulate air bag module connections to the system. Deactivate the System Deactivate the system means to carry out the deactivation procedure. REFER to Deactivation in this procedure. Prove Out the System The air bag warning indicator will illuminate for 3 seconds. Reactivate the System Reactivate the system means to carry out the reactivation procedure. REFER to Reactivation in this procedure. Principles of Operation SRS (SRS) Operation The vehicle is equipped with DC fired single point sensing system. Vehicles equipped with side air bags are equipped with side impact sensors. In the event of a severe frontal or 3-quarter frontal impact, in excess of a predetermined limit, the driver and passenger (if equipped) front air bag(s) will deploy. In the event of a severe full side impact, in excess of a predetermined limit, either the driver or passenger side air bags (if equipped) will deploy. Air bag deployment will only occur, in the event of a severe collision when the ignition key is in the RUN position. RCM The RCM retains full control of the whole system. Providing continual system checks and full diagnostic capabilities, the non-volatile memory stores the fault codes, which are down loaded through the diagnostic link connector to the Ford approved diagnostic tool. A visual warning indicator which is housed within the instrument cluster, is illuminated when the ignition is switched ON for 3 seconds then goes out. If a fault occurs the warning indicator remains illuminated after a further 5 seconds. The RCM provides an auxiliary power supply, sufficient to deploy the air bag(s) for a minimum of 150mS, in the event of a failure in the vehicle power supply during or after an accident. The auxiliary power supply is discharged by the RCM within 60 seconds of the battery ground cable being disconnected. Thus making sure the SRS remains operational. The RCM contains an electronic acceleration sensor to evaluate and process impact data from the frontal direction and a micromachine sensor that acts as the safing sensor for frontal impacts. Provided both the safing sensor and the electronic acceleration sensor detect an impact in excess of a predetermined limit the RCM initiates the circuit to deploy the frontal air bags. Side Impact Sensors The side impact sensors contain an acceleration sensor, filter, amplifier and an application specific integrated circuit for signal transmitting. The side impact sensor processes the impact data against stored data. In the event of a side impact, in excess of a predetermined limit, the side impact sensor will send a signal to the RCM. The sensor opposite the impact side acts as the safing sensor for lateral impacts. If the electronic acceleration sensor also detects a side impact, in excess of a predetermined limit, a signal is then sent from the RCM to deploy the side air bags (if equipped). Air Bag Warning Indicator The air bag warning indicator is incorporated into the instrument cluster, together with the automatic detach detect (ADD) circuit, the air bag warning indicator comes on for 3 seconds at key ON. If the system self tests OK the air bag warning indicator extinguishes, if a fault is detected the air bag warning indicator will illuminate continually from key ON or not illuminate at all, depending on the nature of the fault. The RCM retaining bolts are part of the ground circuit. The ADD circuit is designed to illuminate the air bag warning indicator continuously, if the RCM circuit is broken, either by: - Loss of the RCM power supply.
- Loss of the RCM ground circuit.
- Disconnection of the RCM electrical connector.
Diagnostic evaluation of the SRS can be made through the data link connector (DLC) and Ford approved diagnostic tool to establish the nature of the concern. Inspection and Verification - Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.
