Thomas Transit-Liner C2 User Manual

The TRANSIT-LINER™ C2

What is Multiplex Wiring?

The Transit-Liner™ C2 was designed to be a dependable machine that stays on the road and

transports passengers safely. That’s why we’ve built it with a multiplex wiring system that

makes it easier and quicker to diagnose electrical faults and add optional equipment.

Conventional wiring systems use separate wires to control each electrical function. The

multiplex wiring system allows multiple electronic messages to travel back and forth through

the same datalink wire, just as broadband cable allows telephone, television and Internet

connections to travel through the same line.

The multiplex wiring system’s electronic control modules send information back and forth,

monitoring vehicle components and interpreting messages transmitted through the wires.

Because the modules are remotely controlled by signals, rather than by separate wires,

fewer relays and connectors are required, reducing possible failure points.

Benefits of Multiplex Wiring

IMPROVED RELIABILITY

The multiplex wiring system has reduced the
number of wires in the C2 by more than 40 percent,
from 650 to 350. That means 300 fewer possible
failure points.

IMPROVED DIAGNOSTIC CAPABILITIES

With the multiplex wiring system, onboard computers
capture fault data and relay it to the electronic
instrument cluster in the dash, alerting the driver to
a problem. Fault information also can be downloaded
directly into Freightliner ServiceLink® software for
diagnosis by a service technician.

EASIER TO MODIFY

Each wire is colored and numbered for easy
identification. Switches can be added or moved
quickly and easily without reprogramming by the
dealer. So your bus will spend less time in the shop
and more time on the road.

FLEXIBILITY & SUPPORT

Smart Switches

The Transit-Liner™ C2’s multiplex wiring

system and interchangeable Smart Switches

make adding electrical equipment easier for

service technicians.

ServiceLink

ServiceLink software is a powerful tool that

communicates directly with the electronic

control modules on Thomas Built Buses.

It provides valuable diagnostic/service

information and allows users to test and

monitor circuits.

ServiceLink software allows technicians to

view detailed fault information in a format

that is easy to read and navigate. For easy

maneuverability around the service bay,

it also works offline, allowing for field

troubleshooting and automatically updating

when the computer is connected to the

network. And the latest version of software

includes new features added specifically for

use with the C2.
