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/lamp fault code (DTC/LFC) is not present, 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 a LFC is reported by the customer but is not present when the vehicle comes in for repair, pinpoint test diagnostics cannot be used. Instruct the customer on how to count an LFC. Diagnosing Customer Concerns with Hard DTCs/LFCs WARNING:Do not use substitute air bag simulators when working on the supplemental restraint system. Use only the appropriate tool. Failure to follow these instructions 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 LFC will be displayed and a DTC logged by the air bag control module. Deactivation WARNING:The back up power supply must be depleted, before any work is carried out on the supplemental restraint system. Wait at least one minute after disconnecting the battery ground cable. Failure to follow this instruction may cause personal injury. - Wait at least one minute for the backup power supply energy in the Air Bag Control Module to deplete its stored energy.
WARNING:Place the air bag module on a ground wired bench, with the trim cover facing up to avoid accidental deployment. Failure to follow this instruction may result in personal injury. - Connect the driver air bag simulator to the wiring harness in place of the driver air bag module at the top of the steering column.
- Connect the passenger air bag simulator to the wiring harness in place of the passenger air bag module.
- If equipped, disconnect the driver side air bag module underseat connector.
- Connect the driver side air bag module simulator to the underseat floor harness in place of the side air bag module connector.
- If equipped, disconnect the passenger side air bag module underseat connector.
- Connect the passenger side air bag module simulator to the underseat floor harness in place of the side air bag module connector.
Reactivation WARNING:The air bag simulators must be removed and the air bag modules reconnected when reactivated to avoid non-deployment in a collision. Failure to follow this instruction may result in personal injury. - Wait at least one minute for the backup power supply in the air bag control module to deplete its stored energy.
- Remove the air bag simulator from the wiring harness at the top of the steering column.
- Remove the passenger air bag simulator from the passenger air bag module wiring harness.
- Remove the driver side air bag simulator from the driver side air bag underseat connector.
- Connect and install the driver side air bag module.

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 section. Prove Out the System The air bag warning indicator will illuminate for approximately five seconds. If a fault is detected the indicator will: - fail to illuminate
- illuminate continuously
- flash
Reactivate the System Reactivate the system means to carry out the reactivation procedure. REFER to Reactivation in this section. Principles of Operation Supplemental Restraint System (SRS) Operation The supplemental restraint system for Cougar, is the European derived single point sensing system, with remote side impact crash sensors, for vehicles equipped with side air bags. Single point sensing has been used in Europe since the introduction of Mondeo in 1993. In the event of a severe frontal or three-quarter frontal impact, in excess of a predetermined limit, the driver and passenger 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 bag will deploy. Air bag deployment will only occur, in the event of a severe collision when the ignition key is in the RUN position. Air Bag Control Module The air bag control module is mounted vertically, to facilitate impact sensing along the longitudinal axis. The air bag control module 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 data link connector (DLC) to WDS. A visual warning indicator which is housed within the instrument cluster, is illuminated when the ignition is switched ON for approximately five seconds then goes out. If a fault occurs the warning indicator, depending on the nature of the fault, begins to flash or illuminates continuously. In the event of a failure in the vehicle power supply during or after an accident, the air bag control module provides an auxiliary power supply sufficient to deploy the air bag(s) for a minimum of 150mS. The back up power supply is discharged by the air bag control module within 60 seconds of the battery ground cable being disconnected. Thus making sure the supplemental restraint system remains operational. The air bag control module contains a micro-controller to evaluate and process impact data and two sensors. An electronic accelerometer, which converts the actual acceleration and deceleration force, along the vehicles longitudinal axis into electrical signals, and an electro-mechanical safing sensor which measures deceleration only. Provided both these sensors sense an impact in excess of a predetermined limit, the safing sensor will close the circuit to deploy the frontal air bags. The safing sensor retains the control function to prevent unintentional deployment of the frontal air bags. Side Impact Crash Sensor To facilitate remote lateral impact sensing, the side impact crash sensors are mounted on to the floor pan on either side of the vehicle. Each side impact crash sensor contains a micro-controller which processes signals from two accelerometers within the sensor. In the event of an impact in excess of a predetermined limit, the side impact crash sensor processes the side impact data and initiates a deployment request to the air bag control module. The air bag control module processes this request against stored data, to deploy the side air bag on the side the deployment request was initiated. The air bag control module retains control of the side air bags. 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 3-5 seconds at key ON. If the system self-tests OK the indicator goes out, if a fault is detected the indicator will flash, illuminate continually from key ON or not illuminate at all, depending on the nature of the fault. The ADD circuit is designed to illuminate the air bag warning indicator continuously, if the air bag control module circuit is broken, either by loss of power or ground supply. Diagnostic evaluation of the supplemental restraints system can be made through the DLC and WDS to establish the nature of the fault. Once the DTC is known the appropriate course of action can be selected from the Symptom Chart. Inspection and Verification - Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.
