Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” NAAT0001 The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. The SRS composition which is available to NISSAN MODEL R50 is as follows: I For a frontal collision The Supplemental Restraint System consists of driver air bag module (located in the center of the steer- ing wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable. I For a side collision The Supplemental Restraint System consists of side air bag module (located in the outer side of front seat), side curtain air bag module (locating in the headliner side of front and rear seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision). WARNING: I 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 dealer. I Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. I 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 harness connector (and by yellow harness protector or yellow insulation tape before the harness connectors). Precautions for On Board Diagnostic (OBD) System of A/T and Engine NAAT0002 The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the driver of a malfunction causing emission deterioration. CAUTION: I Be sure to turn the ignition switch “OFF” and disconnect the negative battery terminal before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will cause the MIL to light up. I Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease, dirt, bent terminals, etc.) I Be sure to route and secure the harnesses properly after work. Interference of the harness with a bracket, etc. may cause the MIL to light up due to a short circuit. I Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc. I Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and ECM before returning the vehicle to the customer. SEF289H Precautions NAAT0003 I Before connecting or disconnecting the TCM harness connector, turn ignition switch “OFF” and disconnect negative battery terminal. Failure to do so may damage the TCM. Because battery voltage is applied to TCM even if ignition switch is turned “OFF”. PRECAUTIONS Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” AT-6

SEF291H I When connecting or disconnecting pin connectors into or from TCM, take care not to damage pin terminals (bend or break). Make sure that there are not any bends or breaks on TCM pin terminal, when connecting pin connectors. MEF040DA I Before replacing TCM, perform TCM input/output signal inspection and make sure whether TCM functions properly or not. (Refer to AT-95.) SAT964I I After performing each TROUBLE DIAGNOSIS, perform “DTC (Diagnostic Trouble Code) CONFIRMATION PROCE- DURE”. The DTC should not be displayed in the “DTC CONFIRMA- TION PROCEDURE” if the repair is completed. I Before proceeding with disassembly, thoroughly clean the out- side of the transmission. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign mat- ter. I Disassembly should be done in a clean work area. I Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere with the operation of the transmission. I Place disassembled parts in order for easier and proper assembly. I All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly. I Gaskets, seals and O-rings should be replaced any time the transmission is disassembled. I It is very important to perform functional tests whenever they are indicated. I The valve body contains precision parts and requires extreme care when parts are removed and serviced. Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs and small parts from becoming scattered or lost. I Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight. GI MA EM LC EC FE CL MT TF PD AX SU BR ST RS BT HA SC EL IDX PRECAUTIONS Precautions (Cont’d) AT-7

I Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings and seals, or hold bearings and washers in place during assembly. Do not use grease. I Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling. I Replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to “ATF COOLER SERVICE”, AT-9. I After overhaul, refill the transmission with new ATF. I When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque converter and ATF cooling system. Always follow the procedures when changing A/T fluid. Refer to MA-22, “Changing A/T Fluid”. Service Notice or Precautions NAAT0004 FAIL-SAFE NAAT0004S01 The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major electrical input/output device circuit is damaged. Under Fail-Safe, the vehicle always runs in third gear, even with a shift lever position of “1”, “2” or “D”. The customer may complain of sluggish or poor acceleration. When the ignition key is turned “ON” following Fail-Safe operation, O/D OFF indicator lamp blinks for about 8 seconds. (For “TCM SELF-DIAGNOSTIC PROCEDURE (No Tools)”, refer toAT-48.) The blinking of the O/D OFF indicator lamp for about 8 seconds will appear only once and be cleared. The customer may resume normal driving conditions. Always follow the “WORK FLOW” (Refer to AT-59). The SELF-DIAGNOSIS results will be as follows: The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor. During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated. TORQUE CONVERTER SERVICE NAAT0004S04 The torque converter should be replaced under any of the following conditions: I External leaks in the hub weld area. I Converter hub is scored or damaged. I Converter pilot is broken, damaged or fits poorly into crankshaft. I Steel particles are found after flushing the cooler and cooler lines. I Pump is damaged or steel particles are found in the converter. I Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses have been made. (Converter clutch material may be glazed.) I Converter is contaminated with engine coolant containing antifreeze. I Internal failure of stator roller clutch. I Heavy clutch debris due to overheating (blue converter). I Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are worn or damaged — indicates that lining material came from converter. The torque converter should not be replaced if: I The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles. I The threads in one or more of the converter bolt holes are damaged. PRECAUTIONS Precautions (Cont’d) AT-8

I Transmission failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate lining material in unit and inside the fluid filter. I Vehicle has been exposed to high mileage (only). The exception may be where the torque converter clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic, such as taxi, delivery or police use. ATF COOLER SERVICE NAAT0004S02 Replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Replace radiator lower tank (which includes ATF cooler) with a new one and flush cooler line using cleaning solvent and compressed air. Refer to LC-22, “REMOVALAND INSTALLATION”. OBD-II SELF-DIAGNOSIS NAAT0004S03 I A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through the blinking pattern of the O/D OFF indicator or the malfunction indicator lamp (MIL). Refer to the table on AT-38 for the indicator used to display each self-diagnostic result. I The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memories. Always perform the procedure “HOW TO ERASE DTC” on AT-35 to complete the repair and avoid unnecessary blinking of the MIL. I The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when the O/D OFF indicator lamp does not indicate any malfunctions. - PNP switch - A/T 1st, 2nd, 3rd, or 4th gear function - A/T TCC S/V function (lock-up) *: For details of OBD-II, refer to EC-77, “Introduction”. I Certain systems and components, especially those related to OBD, may use the new style slide- locking type harness connector. For description and how to disconnect, refer to EL-7, “Descrip- tion”. Wiring Diagrams and Trouble Diagnosis NAAT0005 When you read wiring diagrams, refer to the following: I GI-11, “HOW TO READ WIRING DIAGRAMS”. I EL-11, “POWER SUPPLY ROUTING” for power distribution circuit. When you perform trouble diagnosis, refer to the following: I GI-35, “HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES”. I GI-24, “HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”. GI MA EM LC EC FE CL MT TF PD AX SU BR ST RS BT HA SC EL IDX PRECAUTIONS Service Notice or Precautions (Cont’d) AT-9
