Circuit Description The inflatable restraint steering wheel module deployment loop consists of a steering wheel module, steering wheel module coil, steering wheel module high control, and steering wheel module low control circuits. Shorting bars are used on the steering wheel module connector as well as the steering wheel module coil connector which will short together the steering wheel module high and steering wheel module low control circuits when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module during servicing. When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs continuous diagnostic tests on the deployment loops to check for proper

Callout Caution: Refer to SIR Inflator Module Handling and Storage Caution in the Preface section. Caution: Refer to SIR Caution in the Preface section. Preliminary Procedure Disable the supplemental inflatable restraint (SIR) system. Refer to SIR Disabling and Enabling . Retainer Procedure 1 On the back side of the steering wheel, there are 2 access holes. Using a 3-4 mm T handle allen wrench , insert in a cross car (Horizontally) direction and slightly outboard (handle towards I/P) push in 40mm (1 1/2in) to engage release spring. Component Name Steering Wheel Inflatable Restraint Module Procedure 1. Release the connector position assurance (CPA) retainer. 2. Disconnect the electrical connectors. 3. Fully deploy the module before disposal. If the module was replaced under warranty, fully deploy and dispose of the module after the required retention period. Refer to Inflator Module Handling and Scrapping .

Circuit Description The auxiliary brake system provides hydraulic fluid flow within the brake booster if the engine is OFF and the brake is applied. The system consists of the following 3 basic components: • The power brake booster pump motor relay • The power brake booster fluid flow switch • The power brake booster pump motor The multifunction alarm module (MFAM) performs a 4 second bulb check on the AUX BRAKE indicator immediately after the engine is cranked or started. The MFAM illuminates the indicator by supplying voltage to the lamp. During the bulb check, the MFAM also performs a diagnostic which tests the power brake booster pump motor relay, the power brake booster fluid flow switch and the power brake booster

Caution: Refer to Gasoline/Gasoline Vapors Caution in the Preface section. Important: There are several types of Plastic Collar Fuel and Evaporative Emission Quick Connect Fittings used on this vehicle. • Bartholomew (1) • Q Release (2) • Squeeze to Release (3) • Sliding Retainer (4) • Push Down TI (5) The following instructions apply to all of these types of Plastic Collar Quick Connect Fittings except where indicated. 1. Relieve the fuel system pressure before servicing any fuel system connection. Refer to the Fuel Pressure Relief . Caution: Refer to Safety Glasses Caution in the Preface section. Notice: Refer to Fuel and Evaporative Emission Hose/Pipe Connection Cleaning Notice in the Preface section. 2. Using compressed air, blow any dirt out of the

SIR component location affects how a vehicle should be serviced. There are parts of the SIR system installed in various locations around a vehicle. To find the location of the SIR components refer to SIR Identification Views . There are several reasons for disabling the SIR system, such as repairs to the SIR system or servicing a component near or attached to an SIR component. There are several ways to disable the SIR system depending on what type of service is being performed. The following information covers the proper procedures for disabling/enabling the SIR system. SIR Service

Step 1-vehicle preparation
Remove the negative battery cable. With the vehicle standing on a smooth solid surface chock the front wheels. With the help of Jack, the nominal weight of your car, to raise the wheels from the ground. Less weight on Jack stands with the nominal weight of the vehicle, upon being satisfied that the suspension is fully extended. (Do not use wood or concrete blocks to support the vehicle.)
Step 2-remove the coil spring
Put a Jack axis on the left side of the vehicle. Remove the lower bolt with a shock absorber. Lower axis until the coil spring may be removed. Warning: do not put tension or stress on flexible brake line. Remove the jounce bumpers, located in a coil spring. Not to be reused jounce bumper. Drill a hole in the center of the lower spring seat for overhead line pass through a 3/8. Figure "C".
Step 3 – install air Spring
Deflate the spring air coil-Rite and place it inside the coil spring with air, fit down. Then place the upper support at the top of the Coil-Rite (figure & "A" "B"). Cut row air into equal lengths, making sure the ends are cut as straight as soon as possible ("cutting" motion with a razor blade is preferred). The route of the line through the hole in the lower spring seat and along the axis. Insert one end of a line in Setup on the air in the spring.
Step 4-reinstall coil spring
Reinstall the coil spring with coil-Rite on the vehicle. Pass line excess air through holes drilled in the lower spring seat. Attach the lower shock absorber bolt and tighten on the specifications of manufacturers. Figure D. See heat shield notice to install thermal shield. For installation on the right side of the repeat steps 2-5.
Step 5 – set inflation valves
Select the location to mount the inflation valve, this must be a protected area as a rear bumper. Drill two holes 5/16 and go through valves and tighten the nuts. Figure F.
Step 6--routing overhead line
Air line route from air springs inflation valves (figure e). In order to avoid any sharp edges or hot surfaces, as well as the sharp corners. Overhead line can be achieved with nylon ties. Cut off any excess air lines using the method described above and push the end as far as possible in the inflation valve.
Step 7 – inflate and testing
Inflate the air springs with the recommended maximum working pressure (see page 1 for working pressure). With SOAP and water solution to check the air leaks around the valves and valve core. Inflate and deflate in small increments to find the perfect riding conditions for your car.
Step 8-complete
Raise the vehicle, remove the Jack stands and reduce vehicle on Earth. Reattach the battery cable.
