Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Num-
berItem Description
1 Power condition
This shows the condition when the system receives battery positive voltage (can be oper-
ated).
2 Fusible link
The double line shows that this is a fusible link.
The open circle shows current flow in, and the shaded circle shows current flow out.
3Fusible link/fuse loca-
tion
This shows the location of the fusible link or fuse in the fusible link or fuse box. For arrange-
ment, refer to PG section, POWER SUPPLY ROUTING.
4Fuse
The single line shows that this is a fuse.
The open circle shows current flow in, and the shaded circle shows current flow out.
5 Current rating
This shows the current rating of the fusible link or fuse.
6 Connectors
This shows that connector E3 is female and connector M1 is male.
The G/R wire is located in the 1A terminal of both connectors.
Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is SMJ connec-
tor. Refer to PG section, SMJ (SUPER MULTIPLE JUNCTION).
7 Optional splice
The open circle shows that the splice is optional depending on vehicle application.
8 Splice
The shaded circle shows that the splice is always on the vehicle.
9 Page crossing
This arrow shows that the circuit continues to an adjacent page.
The A will match with the A on the preceding or next page.
10 Common connector
The dotted lines between terminals show that these terminals are part of the same connector.
11 Option abbreviation
This shows that the circuit is optional depending on vehicle application.
12 Relay
This shows an internal representation of the relay. For details, refer to PG section, STAN-
DARDIZED RELAY.
13 Connectors
This shows that the connector is connected to the body or a terminal with bolt or nut.

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.
