PRECAUTIONPFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS007KQ
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 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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal 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
harness connectors.

After Front Wipers Operate for 10 Seconds, They Stop for 20 Seconds, and after
repeating the operations five times, they become inoperative
AKS007A2
CAUTION:

When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.

This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
1. CHECK CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (1)

Select “IPDM E/R” on CONSULT-II. With “DATA MONITOR”, confirm
that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper
