1. Vent the air suspension system. WARNING: DO NOT REMOVE AN AIR SPRING UNDER ANY CIRCUMSTANCES WHEN THERE IS PRESSURE IN THE AIR SPRING. DO NOT REMOVE ANY COMPONENTS SUPPORTING AN AIR SPRING WITHOUT EITHER EXHAUSTING THE AIR OR PROVIDING SUPPORT FOR THE AIR SPRING TO PREVENT VEHICLE DAMAGE OR PERSONAL INJURY . 2. Turn the air suspension switch off. WARNING: BEFORE PERFORMING MAINTENANCE ON ANY AIR SUSPENSION COMPONENTS, DISCONNECT THE POWER TO THE SYSTEM BY TURNING OFF THE AIR SUSPENSION SWITCH LOCATED ON THE LH SIDE OF THE LUGGAGE COMPARTMENT TO PREVENT VEHICLE DAMAGE OR PERSONAL INJURY . 3. Raise and support the vehicle. 4. Remove the rear air spring retainer. 5. Lift the bottom of the air spring off the rear axle. 6. Remove the air spring. 1) Disconnect the electrical connector. 2) Push up on the air line retaining ring and disconnect the air line. 3) Remove the air spring. INSTALLATION To install, reverse the removal procedure. NOTE: To avoid damage to the air spring, do not allow suspension to compress before the spring is inflated. When installing the air line into the solenoid, a minimum of 3 mm (1/8 inch) of line must be inserted for proper operation of the air spring.

Refer to Engine Controls Schematics MAF, Secondary Air Injection Pump Bypass Solenoid, IAC and Secondary AIR Pump . Circuit Description The AIR pump is used on this vehicle to lower tail pipe emissions on start-up. The powertrain control module (PCM) grounds the AIR pump relay control circuit, which energizes the AIR pump. The PCM also grounds the AIR solenoid valve control circuit, which energizes the AIR solenoid valve. The AIR solenoid valve opens allowing manifold vacuum to open the AIR control valves. The PCM enables both control circuits when AIR system operation is desired. When the AIR system is active, the AIR pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR control valves replace the conventional check valves. When the AIR system is inactive, the AIR control valves prevent air flow in either direction. DTC P0412 applies to the AIR solenoid control circuit. DTC P0418 applies to the AIR pump relay control circuit. DTC P0410 sets if an air flow problem is detected. The PCM will run two tests using the heated oxygen sensor (HO2S) voltage to diagnose the AIR system. Both tests have two parts. The passive test is performed during regular AIR pump operation. The passive test consists of the following: Passive Test Part 1 When the AIR system is enabled, the PCM monitors the HO2S voltage. If the HO2S voltage goes below a threshold, the PCM interprets this as an indication that the AIR system is operational. Passive Test Part 2 When the AIR system is disabled, the PCM monitors the HO2S voltage. The HO2S voltage should increase above a threshold and switch normally. If both of these tests indicate a pass, no further action is taken. If one of the above tests failed or is inconclusive, the diagnostic will proceed to test two. The active test is performed specifically for diagnostic purposes. Test two consists of the following: Active Test Part 1 During this test the PCM turns the AIR system on during closed loop operation. When the AIR system is activated, the PCM monitors the HO2S voltage. If the AIR system is operating properly, the HO2S voltage should go below a predetermined threshold. Active Test Part 2 The PCM turns the AIR system off. The HO2S voltage should return to above a rich threshold.

SYSTEM OPERATION CHECK An air bag light is located on left side of instrument cluster. Air bag light is used to indicate readiness of system. Light glows when ignition switch is on or engine is started. Light should stay on about 3 seconds while air bag control unit performs an electronic test of system. If air bag light does not glow when ignition is on or does not go out after 3 seconds, a fault probably exists in system. If a fault occurs while ignition is on, it is stored in fault memory. Warning light will then glow and air bag system will be switched off. If warning light glows or flickers while driving, air bag system should be tested. See DIAGNOSIS & TESTING in appropriate AIR BAG RESTRAINT SYSTEM article in ACCESSORIES/SAFETY EQUIPMENT section. * * ADJUSTMENTS AIR BAG SPIRAL SPRING To center spiral spring assembly, turn spring assembly 3 turns from stop in either direction. REMOVAL & INSTALLATION WARNING: Failure to follow air bag service precautions may result in air bag deployment and personal injury. See SERVICE PRECAUTIONS. After component replacement, perform a system operational check to ensure proper system operation. See SYSTEM OPERATION CHECK. AIR BAG MODULE Removal 1) Before proceeding, follow air bag service precautions. See SERVICE PRECAUTIONS. Disable air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM. 2) Air bag module is located in steering wheel. See Fig. 1. Remove air bag module Torx head screws from rear of steering wheel. Lift off air bag module from steering wheel, and tilt air bag module downward. Disconnect air bag module connector. AIR BAG RESTRAINT SYSTEM – 1995 AIR BAG RESTRAINT SYSTEM – 1996

WARNING: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment. WARNING: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment. WARNING: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment. WARNING: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards. WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury. WARNING: Air bag modules with discolored or damaged trim covers must be installed new, not repainted. WARNING: Vehicle sensor orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and properly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches. Please refer to the appropriate vehicle shop manual to determine location of the front air bag sensors. The side air bag sensors are located at or near the base of the B-pillar. To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic procedure again. 1. Disconnect the battery ground cable (14301) and wait at least one minute. For additional information, refer to Section 414-01. 2. Remove the driver air bag module. For additional information, refer to Module — Driver Air Bag in this section. 3. NOTE: Make sure the wheels (1007) are in the straight-ahead position. Remove the steering wheel (3600). For additional information, refer to Section 211-04. 4. Apply two strips of masking tape across the air bag sliding contact (14A664) to prevent accidental rotation when the air bag sliding contact is removed. 5. Place the steering column in the full down tilt position, then remove the tilt wheel handle and shank (3F609). 6. Remove the lower steering column cover. 1. Remove the two bolts. 2. Position the parking brake release aside. 3. Remove the lower steering column cover.
