Confirm the type of the vehicle, if DTC or U1001 is displayed with other DTC, first perform the trouble diagnosis DTC U1000, U1001, refer to DTC U1000, U1001 CAN COMMUNICATION LINE”, these numbers are prescribed by SAE J2012.
In Diagnostic Test Mode II (Self-diagnostic results), these numbers controlled by NISSAN, the troubleshooting for these DTCs need CONSULT-II, when the fail-safe operations for both self-diagnoses occur, MIL illuminates, for the type I vehicle (Refer to How to Check Vehicle Type”, EC-9.
Supplemental Restraint System (SRS) AIR BAG” SEAT BELT PRE-TENSIONER”, 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 certain types, the Supplemental Restraint System consists of driver air bag module (located in the center of the steering 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 spiral cable, the Supplemental Restraint System consists of side air bag module (located in the outer side front seat), side curtain air bag module (located 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 frontal collision).
Information necessary to service the system safely is included in the RS section Service Manual, ¼ To avoid rendering the SRS inoperative, which could increase the risk of personal injury death, ¼ Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system, bag Module, refer RS section.
Driver of a malfunction causing emission deterioration, ¼ Be sure to turn the ignition switch OFF and disconnect the negative battery terminal before any, will cause the MIL light up, ¼ Be sure to connect and lock the connectors securely after work.
Cause the MIL to light up due to the open circuit, ¼ Certain systems and components, especially those related to OBD, may use a new style slidelocking type harness connector, ¼ Be sure to route and secure the harnesses properly after work.
