TROUBLE DIAGNOSIS FOR SYMPTOMS
 Chime does not sound when the system does not det
ect any vehicle ahead. (Diagnose the conditions under
which the system is detecting the vehicle ahead and when the system is malfunctioning. If there is any mal-
function in detecting the vehicle ahead, check the system following the ACS-58, "
Symptom 7 ICC System
Frequently Cannot Detect the Vehicl e Ahead/ Detection Zone Is Short".
1.CHECK ICC WARNING CHIME
With “Active Test” of “ICC”, check t hat ICC warning chime operates normally.
OK or NG
OK >> Determine preceding vehicle detection status when malfunction occurred. If chime should have
sounded: after replacing ICC unit. Perform ICC system running test, and then perform self-diag-
nosis of ICC system again.
NG >> GO TO 2.
2.PERFORM SELF-DIAGNOSIS OF ICC SYSTEM
1. Perform self-diagnosis of ICC system.
2. Check if “DTC 20 CAN COMM CIRCUIT” is indicated.
Is it indicated?
YES >> Refer to ACS-36, "DTC 20 CAN COMM CIRCUIT".
NO >> GO TO 3.
3.PERFORM SELF-DIAGNOSIS OF UNIFIED METER AND A/C AMP.
Perform self-diagnosis of unified meter and A/C amp. Refer to DI-27, "
CONSULT-III Function (METER/M&A)".
OK or NG
OK >> 1. Replace combination meter. 2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
NG >> 1. Repair or replace applicable item.
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
Symptom 6 Driving Force Is HuntingINFOID:0000000001328854
1.CHECK SELF-DIAGNOSIS OF ECM
Perform self-diagnosis of ECM.
OK or NG
OK >> Refer to ACS-58, "Symptom 7 ICC System Frequently Cannot Detect the Vehicle Ahead/ Detec-
tion Zone Is Short".
NG >> 1. Repair or replace applicable parts.
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
Symptom 7 ICC System Frequent ly Cannot Detect the Vehicle Ahead/ Detection Zone
Is Short
INFOID:0000000001328855
The detection function may become unstable in the following cases.
 When the reflector of the vehicle ahead is def icient/ not clean enough to reflect the radar.
 When driving a road with extremely sharp corners.
 When the radar cannot detect the reflector of the vehicle ahead as the vehicle ahead is passing a hill or
passing the peak.
1.VISUAL CHECK
Check ICC sensor body window for contamination and foreign materials.
OK or NG
OK >> If any contamination or foreign materials ar e found, remove them. Then perform ICC system run-
ning test.
NG >> GO TO 2.
2.CHECK FUNCTION

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612925
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
 To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for On Board Diagnosis (OBD) System of A/T and EngineINFOID:0000000001327123
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:
 Be sure to turn the ignition sw itch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/s hort circuit of related switches, sensors, solenoid
valves, etc. Will cause the MIL to light up.
 Be sure to connect and lock the connectors secure ly 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.)
 Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. May cause the MIL to li ght up due to a short circuit.
 Be sure to connect rubber tubes properly afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system, etc.
 Be sure to erase the unnecessary malfunction informa tion (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionINFOID:0000000001327124
 Before connecting or disco nnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect the
battery cable from the negative terminal. Because battery
voltage is applied to TCM even if ignition switch is turned
OFF.
