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 a LFC. Diagnosing Customer Concerns with Hard DTCs/LFCs WARNING:Do not use substitute air bag simulators when working on the SRS. 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) to be disconnected from the SRS, thereby removing the risk of the air bag deployment while diagnostics are carried out. Air bag simulators are required to carry out diagnosis and testing of the air bag 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 SRS. Wait at least one minute after disconnecting the battery ground cable before disconnecting any SRS electrical connector. Failure to follow this instruction may result in personal injury. - Disconnect the battery ground cable.
REFER to: Battery Disconnect (414-01 Battery, Mounting and Cables, General Procedures). - Wait at least one minute for the backup power supply in the air bag control module to deplete its stored energy.

Principles of Operation SRS Operation In the event of a severe frontal or three-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, towards the front of the vehicle, either the driver or passenger side air bag and side air curtain will deploy; in the event of a severe full side impact, in excess of a predetermined limit, towards the rear of the vehicle, only the driver or passenger side air curtain 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 horizontally to the crossmember beneath the floor console, 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 can then be downloaded through the data link connector (DLC) to WDS. 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 150 ms. 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 SRS remains operational. The air bag control module contains a micro-controller to evaluate and process impact data and two micromachine sensors. An electronic accelerometer, which converts the actual acceleration and deceleration force, along the vehicles longitudinal axis into electrical signals. When both these sensors sense an impact, in excess of a predetermined limit, the air bag control module initiates the circuit to deploy the frontal air bags. The two micromachine sensors prevent unintentional deployment of the frontal air bags. Side Impact Sensors The side impact sensors are mounted either side of the vehicle, to facilitate remote lateral impact sensing. A front side impact sensor is mounted under the front seat on each side of the vehicle; a rear side impact sensor is mounted behind the loadspace trim panel on each side of the vehicle. Each side impact sensor contains a micromachine sensor which processes signals from an accelerometer within the sensor. In the event of an impact, in excess of a predetermined limit, the side impact sensor will process the side impact data and initiate 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 and side air curtain as required 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 circuit, the air bag warning indicator illuminates during the self-test for four seconds at key ON and then extinguishes. If a fault is detected the air bag warning indicator will illuminate continuously after a further 0.5 seconds. The automatic detach detect 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. The air bag control module retaining bolts are part of the ground circuit. Diagnostic evaluation of the SRS can be made through the DLC and WDS to establish the nature of the concern. 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.
Visual Inspection Chart Mechanical | Electrical | Floor panel | Electrical connector(s) | Seat | Circuit(s) | | Wiring harness(es) | | Bulb | - If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
