This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SRS and SB section of this Service Man- ual. WARNING: ? To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.  Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section.  Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har- ness connectors.ACCELERATOR CONTROL SYSTEM ACC-3C D E F G H I J K L M A ACC N P O REMOVAL AND INSTALLATION ACCELERATOR CONTROL SYSTEM Component INFOID:0000000001653269 Adjustable Accelerator Pedal WBIA0628E 1. Adjustable accelerator pedal assembly 2. Adjustable brake pedal cable 3. Adjustable brake pedal cable lock tab (part of the cable)ACC-4ACCELERATOR CONTROL SYSTEM Non-adjustable Accelerator Pedal CAUTION:  Before removal and installation, the adjustable accelerator and brake pedals must be in the front- most position, if equipped. This is to align the base position of the accelerator and brake pedals.  Do not disassemble the accelerator pedal assembly.  Do not remove the accelerator pedal position sensor from the accelerator pedal bracket.  Do not disassemble the accelerator pedal adjusting mechanism.  Avoid damage from dropping the accelerator pedal assembly during handling.  Keep the accelerator pedal assembly away from water. Removal and Installation INFOID:0000000001653270 REMOVAL FOR ADJUSTABLE ACCELERATOR PEDAL 1. Move the accelerator and brake pedals to the frontmost position. 2. Turn the ignition switch OFF and disconnect the negative battery terminal. 3. Disconnect the adjustable pedal electric motor electrical connector. 4. Disconnect the adjustable pedal electric motor memory electrical connector, if equipped. 5. Disconnect the accelerator position sensor electrical connector. a. Pull the connector lock back to unlock the connector from the accelerator pedal position sensor as shown. b. Pull up on the connector to disconnect it from the accelerator pedal position sensor as shown. WBIA0629E 1.

Disconnect the adjustable brake pedal cable from the adjustable accelerator pedal.  Release the two lock tabs, then pull the adjustable brake pedal cable to disconnect it from the adjustable accelerator pedal. 7. Remove the two upper and one lower accelerator pedal nuts. 8. Remove the adjustable accelerator pedal assembly. CAUTION:  Do not disassemble the accelerator pedal assembly.  Do not remove the accelerator pedal position sensor from the accelerator pedal bracket.  Do not disassemble the accelerator pedal adjusting mechanism.  Avoid damage from dropping the accelerator pedal assembly during handling.  Keep the accelerator pedal assembly away from water. REMOVAL FOR NON-ADJUSTABLE ACCELERATOR PEDAL 1. Disconnect the negative battery terminal. 2. Disconnect the accelerator position sensor electrical connector. a. Pull the connector lock back to unlock the connector from the accelerator pedal position sensor as shown. b. Pull up on the connector to disconnect it from the accelerator pedal position sensor as shown. 3. Remove the two upper and one lower accelerator pedal nuts. 4. Remove the accelerator pedal assembly. CAUTION:  Do not disassemble the accelerator pedal assembly.  Do not remove the accelerator pedal position sensor from the accelerator pedal bracket.  Avoid damage from dropping the accelerator pedal assembly during handling.  Keep the accelerator pedal assembly away from water. INSTALLATION Installation is in the reverse order of removal. INSPECTION AFTER INSTALLATION  Check that the accelerator pedal moves smoothly within the speci- fied range.  Check that the accelerator pedal smoothly returns to the original position.  Perform an electrical inspection of the accelerator pedal position sensor. Refer to EC-670, “Component Inspection“. CAUTION: When the harness connector of the accelerator pedal position sensor is disconnected, perform ″Accelerator Pedal Released Position Learning″. Refer to EC-497, “Accelerator Pedal Released Position Learning“.
