approach, always begin with
. Read the general informational
and then work your way through the flow chart box by box.
Diagnostic Notes
If a numbered circle appears adjacent to a flow chart box, then
more information is offered in the diagnostic notes. Many dia-
gnostic notes contain supplemental information, descriptions
of various diagnostic tools or references to other parts of the
manual where information on the location and removal of
components may be obtained.
Circuit Diagram/Wire Harness Connector
Cable
When working through a flow chart, refer to the illustrations,
the associated circuit diagram and the wire harness connector
table as necessary. The wire harness connector table for each
circuit diagram identifies the connector number, description,
type and general location.
In order to perform most diagnostic routines, a BREAKOUT
BOX (Part No. B-48115) and a DVOM (Part No. HD-39978)
are required. See
.
To perform the circuit checks with any degree of efficiency, a
familiarity with the various wire connectors is also necessary.
Job/Time Code Values
Dealership technicians filing out warranty claims should use

General Information
The diagnostic check is an organized approach to identifying
a problem caused by an electronic control system malfunction.
NOTE
The engine may be started and run when the trouble codes
are received using a jumper wire on terminals "1" and "2" of
the data link connector. However, if the jumper wire is removed
with the engine running, the check engine lamp will continue
to flash trouble codes. To stop check engine lamp from flashing
codes, turn engine stop switch OFF.
Diagnostic Notes
Each reference number below correlates to a circled number
on the flow chart(s).
1.
Compare engine behavior to tables.
a.
Starts hard. Refer to
.
b.
Hesitates, stumbles, surges, misfires and/or sluggish
performance. Refer to
c.
Engine exhaust emits black smoke or fouls plugs.
Refer to
2.
Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404-B), black socket probes and patch cord.
3.
Connect BREAKOUT BOX (Part No. B-48115) to Elec-
tronic Control Module (ECM). See
All diagnostic codes are listed in
