Section 18-04: Module Communications Network 1998 Mustang Workshop Manual

DESCRIPTION AND OPERATION

--------------------------------------------------------------------------------

Diagnostic Communication Network
The international standards organization (ISO) 9141 communication link:

consists of a single wire, Circuit 70 (LB/W).
provides a common link for communication to an off-board tester through the data link connector (DLC) located under the instrument panel to the right of the steering column.
does not allow module-to-module communications.
Two micro-processor based subsystems are included on this network:

air bag diagnostic monitor system
anti-lock brake system
Fault Tolerance

The ISO 9141 communication link will fail if any of the following occur:

Circuit 70 (LB/W) shorted to ground.
Circuit 70 (LB/W) shorted to battery positive voltage (B+).
the air bag diagnostic monitor loses power or ground supply.
a module failure shorts the ISO 9141 communication link internally.
Purpose

The information within this section is designed to diagnose ISO 9141 communication link concerns. These concerns may:

affect normal functional operations of the vehicle.
be directly related to customer concerns.
be undetectable except during diagnostics.
To properly diagnose a link concern, follow the diagnostic procedure described in this section in the order presented.

Module Identification

Modules included on this ISO 9141 communication link include:

Air bag diagnostic monitor:

located behind the instrument panel on the tunnel of the floorpan.
if communication to the air bag diagnostic monitor (14B056) fails, refer to Communication Systems Diagnostics.
Anti-lock brake control module:

located on the lower RH radiator support.
if communication to the anti-lock brake system (ABS) module fails, refer to Communication Systems Diagnostics.
Diagnostic Communication Network

I don't know maybe a wreck would ruin the computer. I'm just being dumb but I really do think there is a short somewhere that's what it sounds like...

If the circuit is not working it will not communicate. Has nothing to do with how the ecm performs functions

I don't know I think that's what she said. But to bring this thread back to life! Maybe a bad power relay module is wrong with the car???

Acually if it was in a wreck,,they coulda left a couple of ground wires off when it was fixed,,that can cause crazy stuff with the PCM

The one under the finder well on front passenger side. My fuel pump shorted out and ruined mine just recently that's why I say. But if your car is running then maybe not...

Take a pic of it please. Do you guys know where all ground wires are?? I'm sure a ground wire is bad because some things aren't getting any current like this here. If ya have a chance could ya check if it does have current.

If I'm correct that is controlled by the power relay module? But not sure...

No the wire was never broken. But I don't need the part I'm wanting to know if electricity passes through that wire because mine sure doesnt. Do you think I need a new harness for the engine?

That plug you are pointing at looks like the temp sensor for your coolant
