Wait at least one minute after disconnecting the battery ground cable(s) before commencing any repair or adjustment to the supplemental restraint system (SRS), or any component(s) adjacent to the SRS sensors. Failure to follow these instructions 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 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 illuminated air bag warning lamp will be displayed and a DTC logged by the RCM. Deactivation WARNING:To avoid accidental deployment, the RCM backup power supply must be depleted. Wait at least one minute after disconnecting the battery ground cable(s) before commencing any repair or adjustment to the SRS, or any component(s) adjacent to the SRS sensors. Failure to follow these instructions 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 at least one minute for the backup power supply in the RCM to deplete its stored energy.
WARNING:To minimize the possibility of premature deployment, live air bag modules must only be placed on work benches which have been ground bonded and with the trim cover facing up. Failure to follow these instructions may result in personal injury. - Remove the driver air bag module from the vehicle.

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 three seconds. If there is a fault condition, the air bag warning indicator will stay illuminated or illuminate after a five second delay. Reactivate the System Reactivate the system means to carry out the reactivation procedure. REFER to Reactivation in this procedure. Principles of Operation SRS Operation The vehicle is equipped with a DC fired sensing system. In the event of a severe frontal or three-quarter frontal impact, in excess of a predetermined limit, the driver and passenger front air bags and safety belt buckle pretensioners 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, side air curtain (if equipped) and both safety belt buckle pretensioners will deploy. Air bag deployment will only occur, in the event of a severe collision, when the ignition key is in the RUN position. The passenger air bag deactivation (PAD) switch (if equipped) will deactivate the passenger air bag, passenger safety belt buckle pretensioner and passenger side air bag in the event of a severe frontal or side impact; it will not deactivate the passenger side air curtain. RCM The RCM retains full control of the whole system, providing continual system checks and full diagnostic capabilities. The non-volatile memory stores the diagnostic trouble codes, which can then be downloaded through the data link connector (DLC) to WDS. In the event of a failure in the vehicle supply during an accident, the RCM provides a backup power supply, sufficient to deploy the air bag(s) for a minimum of 150 ms. The backup power supply is discharged by the RCM within 60 seconds of the battery ground cable being disconnected. RCM - Vehicles built up to 05/2005 The RCM contains electronic acceleration sensors which measure the longitudinal acceleration and the lateral acceleration and provide both signals to the micro-controller proportional to the amount of acceleration measured. When these sensors sense an impact in excess of a predetermined limit, and the crash sensor or side impact sensor sends a signal to the RCM, the RCM initiates the circuit to deploy the air bag(s). The RCM also contains a safing sensor which enables the front air bags and the safety belt buckle pretensioners in the event of a front impact. The safing sensor also prevents unintentional deployment of the front air bags and safety belt buckle pretensioners in the event of a fault in the electronic acceleration sensor(s). RCM - Vehicles built from 05/2005 The RCM contains two electronic acceleration sensors which measure longitudinal acceleration and one electronic acceleration sensor which measures lateral acceleration. One longitudinal acceleration sensor replaces the crash sensor as a safing sensor. Longitudinal and lateral signals, proportional to the amount of acceleration measured, are fed to a safing micro-controller. The second longitudinal acceleration sensor and the side impact sensors also feed signals, proportional to the amount of acceleration, to a micro-controller. When both micro-controllers sense an impact in excess of a predetermined limit the RCM initiates the circuit to deploy the air bag(s). The safing micro-controller enables the front air bags and the safety belt buckle pretensioners in the event of a front impact. The safing micro-controller also prevents unintentional deployment of the front air bags and safety belt buckle pretensioners in the event of a fault in the electronic acceleration sensor(s). Crash Sensor – Vehicles built up to 05/2005 NOTE:From 05/2005 onwards the vehicle will not be equipped with a crash sensor. The crash sensor contains an acceleration sensor, filter, amplifier and an application specific integrated circuit for signal transmitting and is mounted on the radiator grille opening panel reinforcement. The crash sensor sends a signal at a level determined by the crash severity to the RCM. The RCM will evaluate the signal against stored data and deploy the frontal air bags and safety belt buckle pretensioners if required. Both the crash sensor and the internal RCM longitudinal acceleration sensor must exceed a preset limit to initiate the air bag. Side Impact Sensor The side impact sensors are mounted at the base of the B-pillar on either side of the vehicle, to facilitate remote lateral impact sensing. Each side impact sensor contains an acceleration sensor, filter, amplifier and an application specific integrated circuit for signal transmitting. In the event of an impact, in excess of a predetermined limit, the side impact sensor sends a signal at a level determined by the crash severity to the RCM. The RCM will evaluate the signal against stored data and deploy the side air bag on the side the deployment request was initiated. Both the side impact sensor and the internal RCM lateral acceleration sensor must exceed a preset limit to initiate the air bag. The RCM retains control of the side air bags, side air curtains and safety belt buckle pretensioners. 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 for three seconds at key ON. If the system self-tests OK the indicator extinguishes, if there is a fault condition, the air bag warning indicator will stay illuminated or illuminate after a five second delay. The system is designed to illuminate the air bag warning indicator continuously if the RCM circuit is broken, either by loss of power, ground supply, module disconnect or CAN BUS failure. The RCM retaining bolts are 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 by operating the system.
- Visually inspect for obvious signs of mechanical or electrical damage.
