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 lamp fault code (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 a LFC. Diagnosing Customer Concerns with Hard LFCs WARNING:Do not use substitute air bag simulators when working on the supplemental restraint system. 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, a 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. - Disconnect the battery ground cable.

Glossary Air Bag Module Simulator Air bag module 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. Prove Out the System The air bag warning indicator will illuminate for approximately five seconds: - fail to illuminate
- illuminate continuously
- flash
Reactivate the System Reactivate the system means to carry out the reactivation procedure. Principles of Operations Supplemental Restraint System (SRS) Operation The supplemental restraint system is a single point sensing system, with remote side impact sensors, for vehicles equipped with side air bags. In the event of a severe frontal or angled 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 retains full control of the whole system, providing continual system checks and diagnostic capabilities. A visual warning indicator which is located in 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 comes on continuously. In the event of a failure in the vehicle power supply during an accident, the air bag control module provides an auxiliary power supply, sufficient to deploy the front air bag(s) for a minimum of 150mS. The auxiliary power supply is discharged by the air bag control 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 front air bag module(s). The safing sensor retains the control function to prevent unintentional deployment of the frontal air bags(s). Side Impact Sensors The side impact sensors are mounted to the floor panel on either side of the vehicle, to facilitate remote lateral impact sensing. Each side impact sensor contains a micro-controller which processes signals from two accelerometers within the sensor. The side impact crash sensor processes the side impact data, initiating 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. 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 five seconds at key ON. If the system self-tests OK the indicator extinguishes, 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 or electrical connector disconnection. Inspection and Verification - Verify the customer concern by operating the system.
- Visually inspect for obvious signs of mechanical or electrical damage.
