The speedometer is capable of displaying and clearing
speedometer, tachometer, TSM/TSSM, and ICM/ECM trouble
codes (diagnostic mode).
DIAGNOSTICS
Diagnostic Tips
● For a quick check of speedometer function, a “wow” test
can be performed. See Figure 5-8. Press and hold
odometer reset switch then turn ignition switch ON.
Release reset switch. Background lighting should illumi-
nate, speedometer needle should sweep its full range of
motion, and indicator lamps [battery, security, low fuel
(EFI models) check engine and cruise] should illuminate.

BREAKOUT BOX: EFI
5.7
GENERAL
f1917x9x
The BREAKOUT BOX (Part No. HD-43876) splices into the
main harness. Used in conjunction with a DVOM, it allows cir-
cuit diagnosis of wiring harness and connections without hav-
ing to probe with sharp objects.
NOTE
See wiring diagrams for ECM terminal functions.
INSTALLATION
1.
Remove right saddlebag and side cover. See Figure 5-
10.
2.
Depress latch and remove connector [78B] to release
EFI harness from ECM.

REMOVAL
1. Separate connectors to remove Breakout Box between
ECM and EFI harness.
2. Install connector [78B] to connect EFI harness to ECM.
3. Install right side cover and saddlebag.

WIGGLE TEST

GENERAL
hd39978
The wiggle test indicates the presence of intermittents in a
wiring harness.
PROCEDURE
1. See Figure 5-12. Connect DVOM (Part No. HD-39978) to
wiring harness between the suspect connections. When
diagnosing ECM connections, use a BREAKOUT BOX
(Part No. HD-43876) to simplify the procedure. See 5.7
BREAKOUT BOX: EFI.
Figure 5-12. Fluke 78 Multimeter (DVOM)
(Part No. HD-39978)
2.
Set DVOM to read voltage changes.
3.
Start motorcycle engine and run at idle.
4.
Shake or wiggle harness to detect intermittents. If inter-
mittents are present, radical voltage changes will register
on the DVOM.

Propane is an extremely flammable liquid and vapor.
Vapor may cause flash fire. Keep away from heat, sparks
and flame. Keep container closed. Use only with ade-

death or serious injury.
1WARNING
Read all directions and warnings on propane bottle. Fail-
ure to follow all directions and warnings on bottle could
result in death or serious injury.

NOTE
Do not direct propane stream toward front of engine. If pro-

2. Check the condition of the battery. Perform a voltage test
and recharge if below 12.60V. Check battery connections
and perform load test. Replace the battery if necessary.
See BATTERY in the Touring Service Manual.
3. Connect BREAKOUT BOX (Part No. HD-43876). See 5.7
BREAKOUT BOX: EFI.
4. Remove spark plug cable from spark plug.
a. Visually check condition of plug.
b. See Figure 5-16. Attach cable to SPARK TESTER
(Part No. HD-26792). Clip tester to cylinder head
bolt.
c. While cranking engine, look for spark. Repeat pro-
cedure on other spark plug cables.

Diagnostic Trouble Codes U1300, U1301 or
“BUS Er”
See Figure 5-22. The typical serial data voltage range is 0
volts (inactive) to 7 volts (active). Due to the short pulse, volt-
ages will be much lower on a DVOM. In analog mode, a
DVOM reading serial data will show continuous voltage when
active, typically 0.6-0.8 volts. The range for acceptable opera-
tions is greater than 0 and less than 7.0 volts.
NOTE
Problems in the fuel system or idle air control system may
also create this symptom.

DIAGNOSTICS
Diagnostic Tips
● If serial data is shorted, these codes will automatically
trip the check engine light.
● DTCs P1009 and P1010 may accompany DTCs U1300
and U1301.
Diagnostic Notes
The reference numbers below correlate with the circled num-
bers on the Test 5.12 flow charts.
1. Check for trouble codes. See RETRIEVING DIAGNOS-
TIC TROUBLE CODES under 5.4 CHECKING FOR
DIAGNOSTIC TROUBLE CODES: EFI.
2. Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404A), black socket probes and patch cord.
