Pickup 2WD L4-2559cc 2.6L SOHC (4ZE1) (1993)
Electronic Brake Control Module: Diagram Information and Instructions
Circuit schematics break the entire electrical system into individual circuits. Electrical components that work together are shown together.
Each drawing is arranged so current flows from positive, at top of page to ground, at bottom. The "hot" labels at the top of a fuse indicate when the
ignition switch supplies power to that fuse.
Wires that connect to another circuit are shown with an arrowhead pointing in the direction of current flow. The name of the circuit that shares the
wiring is shown for reference.
POWER AND GROUND SUPPLY
"See Fuse Box Details" indicates there are connections to other circuits that are not shown. All shared circuits are shown on the Fuse Box Details
"See Ground Distribution" indicates there are shared ground circuits which are shown on the ground distribution schematic.
No attempt is made to represent the location or proximity of components. If a wire is actually 4 foot or 4 inches, it will be represented without
regard in the schematic.
Component/Connector Location and I.D.
COMPONENT AND CONNECTOR LOCATION
Supplied with the wiring schematic is a component location index. The index lists the correct photograph for the components and connectors
listed. The photographs are illustrated in COMPONENT/CONNECTOR I.D. AND LOCATION.
Harness routing and selected connectors related to the system are illustrated in this section. The connectors are illustrated in
COMPONENT/CONNECTOR I.D. AND LOCATION.
All connectors with more than 2 terminals are illustrated in this section. The connectors are illustrated in COMPONENT/CONNECTOR I.D.
Fuse Box Details
The fuse box details schematic shows all the wiring between a fuse and the components connected to the output side of the fuse. It shows what
supplies power to the fuse and when it is energized.
The ground distribution schematics show which components share a common ground point. This information can be very helpful in diagnosing
inoperative circuits. If more than one components are not working and they share a common ground, it is likely the ground circuit is faulty.
However, if one of the circuits is operative and the other is not, you know the ground and the wire are good up to a splice.
Light Switch Details
The light switch details schematic shows all the wiring between the light switch/relays and the components connected to the output side of the light
The Power distribution schematic shows the wiring from the battery and alternator to the:
- Starter solenoid
- Fuse box
- Light switch
- Ignition switch
- Fuse link
The first component after a fuse link is shown. In certain instances, the first component after a fuse box, fuse and light switch is shown.
All fuses in the schematic are "Hot At All Times", since battery voltage is the direct source.
