Hard wired circuitry connects the CTM to the electrical
system of the vehicle. These hard wired circuits
are integral to several wire harnesses, which are
routed throughout the vehicle and retained by many
different methods. These circuits may be connected to
each other, to the vehicle electrical system and to the
CTM through the use of a combination of soldered
splices, splice block connectors, and many different
types of wire harness terminal connectors and insulators.
Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further
details on wire harness routing and retention, as well
as pin-out and location views for the various wire
harness connectors, splices and grounds.
All versions of the CTM for this model are serviced
only as a complete unit. Many of the electronic features
in the vehicle controlled or supported by the
high-line or premium versions of the CTM are programmable
using the DRBIIIt scan tool. In addition,
the high-line/premium CTM software is Flash compatible,
which means it can be reprogrammed using
Flash reprogramming procedures. However, if any of
the CTM hardware components are damaged or
faulty, the entire CTM unit must be replaced. The
8E - 2 ELECTRONIC CONTROL MODULES BR/BE
BODY CONTROL/CENTRAL TIMER MODULE (Continued)
base version of the CTM and the hard wired inputs
or outputs of all CTM versions can be diagnosed
using conventional diagnostic tools and methods;
however, for diagnosis of the high-line or premium
versions of the CTM or the CCD data bus, the use of
a DRBIIIt scan tool is required. Refer to the appropriate
diagnostic information.
