Revision: September 2009 EC-1599 2010 Altima PRECAUTIONS [VQ35DE] < PRECAUTION > PRECAUTION PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000005716652 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision 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 AIR BAG” and “SEAT BELT” of this Service Manual 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 AIR BAG” • 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 harness connectors PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury • When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least minutes before performing any service Precautions For Xenon Headlamp Service INFOID:0000000005716653 WARNING: Comply with the following warnings to prevent any serious accident • Disconnect the battery cable (negative terminal) or the power supply fuse before installing, removing, or touching the xenon headlamp (bulb included) The xenon headlamp contains high-voltage generated parts • Never work with wet hands • Check the xenon headlamp ON-OFF status after assembling it to the vehicle Never turn the xenon headlamp ON in other conditions Connect the power supply to the vehicle-side connector (Turning it ON outside the lamp case may cause fire or visual impairments.) • Never touch the bulb glass immediately after turning it OFF It is extremely hot CAUTION: Comply with the following cautions to prevent any error and malfunction • Install the xenon bulb securely (Insufficient bulb socket installation may melt the bulb, the connector, the housing, etc by high-voltage leakage or corona discharge.) • Never perform HID circuit inspection with a tester • Never touch the xenon bulb glass with hands Never put oil and grease on it • Dispose of the used xenon bulb after packing it in thick vinyl without breaking it • Never wipe out dirt and contamination with organic solvent (thinner,

diagnostic system It will illuminate the malfunction indicator lamp (MIL) to warn the driver of a malfunction causing emission deterioration CAUTION: • Always to turn the ignition switch OFF and disconnect the negative battery cable before any repair or inspection work The open/short circuit of related switches, sensors, solenoid valves, etc will cause the MIL to illuminate • Always to connect and lock the connectors securely after work A loose (unlocked) connector will cause the MIL to illuminate due to the open circuit (Always the connector is free from water, grease, dirt, bent terminals, etc.) • Certain systems and components, especially those related to OBD, may use a new style slide-locking type harness connector For description and how to disconnect, refer to PG-60, "Description" (coupe) or PG-132, "Description" (sedan) • Always route and secure the harnesses properly after work The interference of the harness with a bracket, etc may cause the MIL to illuminate due to the short circuit • Always to connect rubber tubes properly after work A misconnected or disconnected rubber tube may cause the MIL to illuminate due to the malfunction of the EVAP system or fuel injection system, etc • Always to erase the unnecessary malfunction information (repairs completed) from the ECM and TCM (Transmission control module) before returning the vehicle to the customer General Precautions INFOID:0000000005431923 • Always use a 12 volt battery as power source • Never attempt to disconnect battery cables while engine is running • Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect negative battery cable Failure to so may damage the ECM because battery voltage is applied to ECM even if ignition switch is turned OFF • Before removing parts, turn ignition switch OFF and then disconnect battery ground cable E F G H I J K L M N SEF289H O • Never disassemble ECM • If a battery cable is disconnected, the memory will return to the ECM value The ECM will now start to self-control at its initial value Thus, engine operation can vary slightly in this case However, this is not an indication of a malfunction Never replace parts because of a slight variation • If the battery is disconnected, the following emission-related diagnostic information will be lost within 24 hours - Diagnostic trouble codes - 1st trip diagnostic trouble codes - Freeze frame data - 1st trip freeze frame data Revision: September 2009 EC-1601 2010 Altima P PRECAUTIONS < PRECAUTION > - System readiness test (SRT) codes - Test values • When connecting ECM harness connector, fasten (B) it securely with a lever (1) as far as it will go as shown in the figure - ECM (2) - Loosen (A) [VQ35DE] PBIB2947E • When connecting or disconnecting pin connectors into or from ECM, never damage pin terminals (bends or break) Check that there are not any bends or breaks on ECM pin terminal, when connecting pin connectors • Securely connect ECM harness connectors A poor connection can cause an extremely high (surge) voltage to develop in coil and condenser, thus resulting in damage to ICs • Keep engine control system harness at least 10 cm (4 in) away from adjacent harness, to prevent engine control system malfunctions due to receiving external noise, degraded operation of ICs, etc • Keep engine control system parts and harness dry • Before replacing ECM, perform ECM Terminals and Reference Value inspection and check that the ECM functions properly Refer to EC-1531, "Reference Value" • Handle mass air flow sensor carefully to avoid damage • Never clean mass air flow sensor with any type of detergent • Never disassemble electric throttle control actuator • Even a slight leakage in the air intake system can cause serious incidents • Never shock or jar the camshaft position sensor (PHASE), crankshaft position sensor (POS) PBIB0090E MEF040D • After performing each TROUBLE DIAGNOSIS, perform DTC Confirmation Procedure or Component Function Check The DTC should not be displayed in the DTC Confirmation Procedure if the repair is completed The Component Function Check should be a good result if the repair is completed SEF217U Revision: September 2009 EC-1602 2010 Altima PRECAUTIONS < PRECAUTION > • When measuring ECM signals with a circuit tester, never allow the two tester probes to contact Accidental contact of probes will cause a short circuit and damage the ECM power transistor [VQ35DE] A EC C D E F G SEF348N • B1 indicates bank 1, B2 indicates bank as shown in the figure • Never operate fuel pump when
