1.0 INTRODUCTION
The procedures contained in this manual include
all the specifications, instructions and graphics
needed to diagnose 2005 ZB/SRT-10 body system
problems. The diagnostics in this manual are based
on the failure condition or symptom being present
at the time of diagnosis.
Please follow the recommendations below when
choosing your diagnostic path.
1. First make sure the DRBIII
t
is communicating
with the appropriate modules; i.e., if the
DRBIII
t
displays a “No Response” or a “Bus
6
Signals Open” condition, you must diagnose that
first.
2. Read DTC’s (diagnostic trouble codes) with the
DRBIII
t
.
3. If no DTC’s are present, identify the customer
complaint.
4. Once the DTC or customer complaint is identi-
fied, locate the matching test in the Table of
Contents and begin to diagnose the symptom.
All component location views are in Section 8.0. All
connector pinouts are in Section 9.0. All schematics
are in Section 10.0. All Charts and Graphs are in
Section 11.0.
An * placed before the symptom description indi-
cated a customer complaint.
When repairs are required, refer to the appropri-
ate service information for the proper removal and
repair procedure.
Diagnostic procedures change every year. New
diagnostic systems may be added: carryover sys-
tems may be enhanced. READ THIS MANUAL
BEFORE TRYING TO DIAGNOSE A VEHICLE
DIAGNOSTIC TROUBLE CODE. It is recom-
mended that you review the entire manual to be-
come familiar with all the new and changed diag-
nostic procedures.
This book reflects many suggested changes from
readers of past issues. After using this book, if you

3.0 SYSTEM DESCRIPTION AND
FUNCTIONAL OPERATION
The body system on the 2005 ZB consists of a
combination of modules that communicate over the
PCI bus (Programmable Communication Interface
multiplex system). Through the PCI bus, informa-
tion about the operation of vehicle components and
circuits is relayed quickly to the appropriate mod-
ule(s). All modules receive all the information trans-
mitted on the bus even though a module may not
require all information to perform it’s function. It
will only respond to messages “addressed” to it
through a binary coding process. This method of
data transmission significantly reduces the com-
plexity of the wiring in the vehicle and the size of
wiring harnesses. All of the information about the
functioning of all the systems is organized, con-
trolled, and communicated by the PCI bus, which is
described in the Communication Section of this
general information.
