SERVICE INFORMATION FOR ELECTRICAL INCIDENT
●Heat sensitive
●Freezing
●Water intrusion
●Electrical load
●Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
Vehicle Vibration
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustra-
tion.
CONNECTORS & HARNESS
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
HINT
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
SENSORS & RELAYS
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
ENGINE COMPARTMENT
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
●Connectors not fully seated.
●Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
●Wires laying across brackets or moving components.
●Loose, dirty or corroded ground wires.
●Wires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the
wiring for continuity.
BEHIND THE INSTRUMENT PANEL
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.

CONSULT-II CHECKING SYSTEM
Checking Equipment
EAS000GB
When ordering the following equipment, contact your NISSAN/INFINITI distributor.
NOTE:
●The CONSULT-II must be used in conjunction with a program card.
CONSULT-II does not require loading (Initialization) procedure.
●Be sure the CONSULT-II is turned off before installing or removing a program card.
CONSULT-II Data Link Connector (DLC) CircuitEAS000PD
INSPECTION PROCEDURE
If the CONSULT-II cannot diagnose the system properly, check the following items.
NOTE:
The DDL1 and DDL2 circuits from DLC pins 12, 13, 14 and 15 may be connected to more than one system. A
short in a DDL circuit connected to a control unit in one system may affect CONSULT-II access to other sys-
tems.
To o l n a m eDescription
NISSAN CONSULT-II
1. CONSULT-II unit (Tester internal soft: Resident
version 3.3.0) and accessories
2. Program card AED01A and AEN00B (For
NATS)
To confirm the best combination of these
softwares, refer to CONSULT-II Operation
Manual.
SGI083A
SGI125A
Symptom Check item
CONSULT-II cannot access
any system.
●CONSULT-II DLC power supply circuit (Terminal 8) and ground circuit (Terminal 4) (For detailed
circuit, refer to “MIL & Data Link Connectors Wiring Diagram” in EC section.)
●CONSULT-II DLC cable.
CONSULT-II cannot access
individual system. (Other sys-
tems can be accessed.)
●CONSULT-II program card (Check the appropriate CONSULT-II program card for the system.
Refer to "Checking Equipment".)
●Power supply and ground circuit for the control unit of the system (For detailed circuit, refer to wir-
ing diagram for each system.)
●Open or short circuit between the system and CONSULT-II DLC (For detailed circuit, refer to wiring
diagram for each system.)
