There are two types of DTCs: current and historic. If a DTC is
stored, it can be read using either a computer-based diagnostic
package called DIGITAL TECHNICIAN II (Part No. HD-48650)
or odometer self-diagnostics. See
.
NOTES
•
To differentiate between current and historic DTCs, a
computer-based diagnostic package called DIGITAL
TECHNICIAN II (Part No. HD-48650) must be employed.
•
All DTCs reside in the memory of the ECM, TSM/TSSM/
HFSM, speedometer or tachometer until the DTC is
cleared by use of the odometer self-diagnostics. See
•
A historic DTC is also cleared after a total of 50 trips has
elapsed. A trip consists of a start and run cycle. After the
50 trip retention period, the DTC is automatically erased
from memory providing that no subsequent faults of the
same type are detected in that period.
Current
Current DTCs are those which are present during the current
ignition cycle. See the appropriate flowcharts for solutions.
Historic
If a particular problem happens to resolve itself, the active
status problem is dropped and it becomes a historic DTC rather
than a current DTC.
Historic DTCs can only be retrieved using a computer-based
diagnostic package called DIGITAL TECHNICIAN II (Part
No. HD-48650).
Historic DTCs are stored for 50 ignition cycles after any DTC
was last set as current to assist in the diagnosis of intermittent
faults. On the 50th cycle, the DTC will clear itself. The check
engine lamp will not indicate the existence of only historic
DTCs.
It is important to note that historic DTCs will exist whenever
the system indicates the existence of a current fault. See
4.4 CHECKING FOR DIAGNOSTIC TROUBLE CODES: EFI,
Multiple Diagnostic Trouble Codes
if multiple DTCs are found.
Diagnostic charts are designed for use with current DTCs and
as a result they frequently suggest part replacement. When
diagnosing a historic DTC the charts can be helpful but should
not lead to part replacement without verification the part is
faulty.

The engine management system provides two levels of dia-
gnostics.
•
The most sophisticated mode employs a computer-based
diagnostic package called DIGITAL TECHNICIAN II (Part
No. HD-48650).
•
The second mode requires using the odometer self dia-
gnostics. Speedometer, tachometer (if equipped),
TSM/TSSM/HFSM and ECM DTCs can be accessed and
cleared. See

. If belt deflection is not correct, adjust per the following
procedure.
NOTE
Rear brake line is clamped tightly to rear fork to avoid chafing
of brake line in clamp. A small amount of slack must be main-
tained in rear brake line between clamp and rear caliper when
rear wheel is adjusted.

clamp (3) on rear brake line (2).
2.
See
. Remove e-clip (1) and loosen rear axle
nut (4). Turn axle adjuster nuts (2) on each side of rear
fork clockwise to decrease belt deflection (increase ten-
sion), or counterclockwise to increase belt deflection
(decrease tension). Turn both adjuster nuts the same
number of turns in order to maintain approximate alignment
of rear wheel.
3.
Check rear wheel alignment. Wheel must be centered in
rear fork. See

Do not exceed specified torque when tightening axle nut.
Exceeding torque can cause wheel bearings to seize during
vehicle operation, which could result in death or serious
injury. (00408e)

Checking Wheel Alignment
Check vehicle alignment according to following proced-
ures. Incorrect alignment can adversely affect stability and
handling, which could result in death or serious injury.
(00287a)
1.
Obtain AXLE ALIGNMENT PLUG SET (Part No. HD-
48856). See
. Insert axle alignment plugs (1,
2) into left and right ends of rear axle.
2.
For XL Models: See
. Fabricate an alignment
tool using a piece of 1/8-in. (3.175 mm) diameter aluminum
welding rod 21.5 in. (546 mm) long. Grind one end down
to a blunt point. Use pliers to bend rod at a 90 degree
angle, 2.25 in. (57 mm) from the blunt point, as shown.
Place a snug-fitting rubber grommet (2) on rod to act as
a slide measurement indicator.
3.
For XR Models: See
. Fabricate an alignment
tool using a piece of 1/8-in. (3.175 mm) diameter aluminum
welding rod 22.375 in. (568 mm) long. Grind one end down
to a blunt point. Use pliers to bend rod as shown. Place a
snug-fitting rubber grommet (2) on rod to act as a slide
measurement indicator.
4.
. Insert blunt point of alignment tool in rear fork
pivot bolt dimple (2) on right side of rear fork (3). Slide
rubber grommet along tool shaft until it aligns with hole in
center of alignment plug (5). Measure distance from
pointed end of alignment tool to grommet. Repeat meas-
urement for left side of rear fork.

Loosen rear axle nut (4).
3.
On side of rear fork that has longer distance from pivot
bolt to axle center, turn nut (2) on axle adjuster (3) coun-
terclockwise to shorten distance. Adjust axle until left and
right side alignment measurements are equal.
NOTES
•
Keep axle adjuster mechanisms firmly seated (under ten-
sion) on each side of rear fork during wheel alignment
procedures above. Do so by applying moderate upward
force on lower span of rear belt. This tensions rear belt,
which holds rear axle forward against both adjuster
mechanisms.
•
Do not tighten rear axle nut or install new e-clip until after
checking rear drive belt tension.

NOTE
Rear brake line is clamped tightly to rear fork to avoid chafing
of brake line in clamp. If rear axle has been moved forward or
back, make sure there is a small amount of slack in rear brake
line between clamp and rear caliper. If necessary, loosen clamp
screw, reposition brake line, then tighten screw. See

Do not exceed specified torque when tightening axle nut.
Exceeding torque can cause wheel bearings to seize during
vehicle operation, which could result in death or serious
injury. (00408e)

INITIAL DIAGNOSTIC CHECK: EFI
GENERAL
TOOL NAME
PART NUMBER
DIGITAL TECHNICIAN II
HD-48650
To locate faulty circuits or other system problems, follow the
diagnostic flowcharts in this section. For a systematic approach,
always begin with
4.5 INITIAL DIAGNOSTIC CHECK: EFI,
. Read the general information and then work your way
through the flowchart box by box.
Diagnostic Notes
If a numbered circle appears adjacent to a flowchart 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
Table
When working through a flowchart, 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
and a digital volt/ohmmeter (DVOM) are required. See
To perform the circuit checks with any degree of efficiency, a
familiarity with the various wire connectors is also necessary.
Reprogramming ECM
Diagnostic charts frequently suggest ECM replacement. In the
event an ECM needs to be replaced, it must be reprogrammed
using a computer-based diagnostic package called DIGITAL
TECHNICIAN II (Part No. HD-48650). See your dealer. Pass-
word learn procedure must also be performed. See

General Information
The diagnostic check is an organized approach to identifying
a problem caused by an electronic control system malfunction.
Diagnostic Tips
•
If odometer reads "BUS Er" with the ignition switch turned
ON (engine stop switch at RUN with the engine off), check
data bus for an open or short to ground. between data link
connector [91A] terminal 3 and ECM connector [78B] ter-
minal 5, TSM/TSSM/HFSM connector [30B] terminal 3,
speedometer connector [39B] terminal 2 (XL), terminal C
(XR) or tachometer (if equipped) connector [108B] terminal
2.
•
Check for an open data test terminal between data link
connector [91A] terminal 3 and TSM/TSSM/HFSM con-
nector [30B] terminal 3. With ignition key turned ON, serial
data bus voltage should be typically 0.6-0.8 volts. The
range of acceptable voltage is 0-7.0 volts.
•
To identify intermittents, wiggle instrument and/or vehicle
harness while performing steps in the Diagnostic Check
charts.
Diagnostic Notes
Each reference number below correlates to a circled number
on the flowchart(s).
1.
Compare engine behavior to symptoms tables.
a.
Starts hard. Refer to
b.
Hesitates, stumbles, surges, misfires and/or sluggish
