2004 CHECKING FOR DIAGNOSTIC TROUBLE CODES 2.1

CHECK ENGINE LAMP
To diagnose electronic control module (ECM) or ignition con­trol module (ICM) system problems, start by observing the behavior of the check engine lamp.
NOTES
See Figure 2-2. “Key ON” means that the ignition key is
turned to ON and the engine stop switch is set to RUN (although the engine is
When the ignition switch is turned ON, the check engine
lamp will illuminate for approximately four seconds and then turn off.
If the check engine lamp is not illuminated at Key ON. See 2.2 INITIAL DIAGNOSTIC CHECK: SPEEDOME-
TER.
If the check engine lamp comes on late (after 20 sec-
onds). See 2.2 INITIAL DIAGNOSTIC CHECK: SPEED-
OMETER.
If the check engine lamp fails to turn OFF after the initial
four second period. See 2.2 INITIAL DIAGNOSTIC
CHECK: SPEEDOMETER.
not
running).
Figure 2-2. Ignition Switch (FLTR, FLHT/C/U)
1. See Figure 2-3. After lamp turns off after being illumi­nated for the first four second period, one of three situa­tions may occur.
a. The lamp remains off. This indicates there are no
current fault conditions or stored diagnostic trouble codes (DTC) currently detected by the ignition con­trol module (ICM) or electronic control module (ECM).
b. The lamp stays off for only four seconds and then
comes back on for an eight second period. This indi­cates an diagnostic trouble code is stored, but no current diagnostic trouble code exists.
c. If the lamp remains on beyond the eight second
Figure 2-1. Speedometer
period, then a current diagnostic trouble code exists.
2. See CODE TYPES which follows for a complete descrip- tion of diagnostic trouble code formats.
NOTES
Some diagnostic trouble codes can only be fully diagnosed during actuation. For example, a problem with the ignition coil will be considered a current fault even after the problem is corrected, since the ECM/ICM will not know of its resolution until after the coil is exercised by vehicle start sequence. In this manner, there may sometimes be a false indication of the current diagnostic trouble code.

SECURITY LAMP

To diagnose TSM/TSSM system problems, start by observing the behavior of the security lamp.
NOTES
To provide an indication of TSM/TSSM diagnostic trouble codes, the security lamp is enabled on all models.
See Figure 2-2. “Key ON” means that the ignition key is
turned to ON and the engine stop switch is set to RUN (although the engine is
When the ignition switch is turned ON, the check engine lamp will illuminate for approximately four seconds and then turn off.
If the check engine lamp is not illuminated at Key ON,
see 2.2 INITIAL DIAGNOSTIC CHECK: SPEEDOME-
TER.
If the check engine lamp comes on late (after 20 sec­onds), see 2.2 INITIAL DIAGNOSTIC CHECK: SPEED-
OMETER.
If the check engine lamp fails to turn OFF after the initial
four second period, see 2.2 INITIAL DIAGNOSTIC
CHECK: SPEEDOMETER.
not
running).
1. See Figure 2-3. After lamp turns off after being illumi- nated for the first four second period, one of three situa­tions may occur.
a. The lamp remains off. This indicates there are no
current fault conditions or stored diagnostic trouble codes currently detected by the ignition control mod­ule (ICM) or electronic control module (ECM).
b. The lamp stays off for only four seconds and then
comes back on for an eight second period. This indi­cates an diagnostic trouble code is stored, but no current diagnostic trouble code exists.
c. If the lamp remains on beyond the eight second
period, then a current diagnostic trouble code exists.
2. See CODE TYPES which follows for a complete descrip­tion of diagnostic trouble code formats.
NOTE
Some diagnostic trouble codes can only be fully diagnosed during actuation. For example, a problem with the turn signals will be considered a current fault even after the problem is corrected, since the TSM/TSSM will not know of its resolution until after the turn signals are activated. In this manner, there may sometimes be a false indication of a diagnostic trouble code.

CODE TYPES

There are two types of diagnostic trouble codes (DTCs): cur­rent and historic. If a diagnostic trouble code is stored, it can be read using speedometer self diagnostics. See 2.3
SPEEDOMETER SELF DIAGNOSTICS.
All diagnostic trouble codes reside in the memory of the ECM/ICM, TSM/TSSM, speedometer or tachometer until the code is cleared by use of the speedometer self diagnostics. See 2.3 SPEEDOMETER SELF DIAGNOSTICS.
A historic diagnostic trouble code 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 diagnostic trouble code is automatically erased from memory providing that no subsequent faults of the same type are detected in that period.

Current

Current diagnostic trouble codes are those which presently disrupt motorcycle operation. See the appropriate flow charts for solutions.

Historic

Historic diagnostic trouble codes can only be identified as his­toric using a computer based diagnostic package called DIG­ITAL TECHNICIAN (Part No. HD-44750), when historic diagnostic codes are present.
If a particular problem happens to resolve itself, the active status problem is dropped and it becomes a historic fault rather current fault.
Historic diagnostic trouble codes are stored for a length of time to assist in the diagnosis of intermittent faults.
It is important to note that historic diagnostic trouble codes may also be present whenever the system indicates the exist­ence of a current fault. See MULTIPLE DIAGNOSTIC TROU-
BLE CODES if multiple diagnostic trouble codes are found.

RETRIEVING DIAGNOSTIC TROUBLE CODES

The engine management system provides two levels of diag­nostics.
The most sophisticated mode employs a computer based diagnostic package called DIGITAL TECHNICIAN (Part No. HD-44750).
The second mode requires using the speedometer self diagnostics. Speedometer, tachometer (if equipped), TSM/TSSM and ECM diagnostic trouble codes can be accessed and cleared. See 2.3 SPEEDOMETER SELF
DIAGNOSTICS.

MULTIPLE DIAGNOSTIC TROUBLE CODES

While it is possible for more than one fault to occur and set more than one diagnostic trouble code, there are several con­ditions which may result in tic trouble codes:
Serial data diagnostic trouble codes (DTC U1016, U1064, U1097, U1255, U1300 and U1301) may be accompanied by other codes. codes before resolving the other codes.

INITIAL DIAGNOSTIC CHECK: SPEEDOMETER 2.2

GENERAL

Constant power is supplied to the speedometer through terminal 5 of connector [39]. The speedometer turns on when power is applied to terminal 1 of connector [39]. The speedometer goes through an initialization sequence every time power is removed and re-applied to terminal 6. The visible part of this sequence is the check engine lamp (in “run” mode), security lamp (models with security only), backlighting, odometer and fuel level (EFI only). Upon key ON, the check engine lamp and security lamp will illuminate for 4 seconds and then (if parameters are normal) go out.
To locate faulty circuits or other system problems, follow the diagnostic flow charts and tests in this section. For a systematic approach, always begin with INITIAL DIAG-
NOSTICS which follows. Read the general information
and then work your way through the flow chart box by box.
Loss of power on any of the four power inputs will change speedometer behavior. Refer to Ta bl e 2-1.
Speedometer Function Chart-Loss Of Input.

Diagnostic Notes

If a numbered circle appears adjacent to a flow chart box, then more information is offered in the diagnostic notes. Many diagnostic 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 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 and a digital volt/ohm meter (DVOM) are required. See 2.5
BREAKOUT BOX: SPEEDOMETER.
To perform the circuit checks with any degree of efficiency, a familiarity with the various wire connectors is also necessary.

INITIAL DIAGNOSTICS

Diagnostic Tips

If Speedometer reads “BUS Er” with the ignition key
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 ICM connector [10B] terminal 12 (carbureted models), ECM connector [78B] terminal 5 (EFI models), TSSM connec­tor [30B] terminal 3, Speedometer connector [39B] termi­nal 2 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 connector [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 greater than 0 and less than 7.0 volts.
To identify intermittents, wiggle instrument and/or vehicle
harness while performing steps in the Diagnostic Check charts.

Diagnostic Notes

The reference numbers below correlate with the circled num­bers on the diagnostic check flow charts. See page 2-11.
1. Connect BREAKOUT BOX (Part No. HD-42682) and INSTRUMENT HARNESS ADAPTERS (Part No. HD-
46601) between wire harness and speedometer.
All Speedometer diagnostic trouble codes are listed on page
2-6 in Ta bl e 2-2.

Other Codes

See 3.9 INITIAL DIAGNOSTIC CHECK: TSM/TSSM for any diagnostic trouble codes related to the turn signal module (TSM) or turn signal security module (TSSM).
See 4.4 INITIAL DIAGNOSTIC CHECK: ICM for any diagnos- tic trouble codes related to the ignition control module (ICM).

SPEEDOMETER SELF DIAGNOSTICS 2.3

GENERAL

The speedometer is capable of displaying and clearing speedometer, tachometer, TSM/TSSM, and ICM/ECM diag­nostic trouble codes (diagnostic mode).

DIAGNOSTICS

Diagnostic Tips

For a quick check of speedometer function, a “wow” test
can be performed. Press and hold odometer reset switch then turn ignition switch ON. Release reset switch. Back­ground lighting should illuminate, speedometer needle should sweep its full range of motion, and indicator lamps [battery, security, low fuel (EFI models) check engine and cruise should illuminate. Some lamps may illuminate even though they do not apply to the vehicle. For example, the cruise lamp may illuminate although this feature does not apply to some models.
If instrument module fails “wow” test, check for battery,
ground, ignition, speedometer reset switch and acces­sory to speedometer. If any feature in the speedometer is non-functional, see 2.2 INITIAL DIAGNOSTIC CHECK:
SPEEDOMETER.

Diagnostic Notes

Use of speedometer self diagnostics assumes that DIGITAL TECHNICIAN (Part No. HD-44750) is not available.
The reference numbers below correlate with the circled num­bers in the Speedometer Self Diagnostics (chart)
1. To exit diagnostic mode, turn ignition switch OFF.
2. To clear diagnostic trouble codes (DTCs) for selected module, press speedometer reset switch for more than 5 seconds when code is displayed. This procedure will clear all diagnostic trouble codes for selected module.

SPEEDOMETER THEORY OF OPERATION

The speedometer consists of a vehicle speed sensor, ICM/ ECM, odometer reset switch and the speedometer. The vehi­cle speed sensor is mounted on the right side of transmission case below the starter. The sensor circuitry is that of a Hall­Effect sensor that is triggered by the gear teeth of 4th gear on the transmission mainshaft.
The output from the sensor is a series of pulses that are inter­preted by ICM/ECM circuitry, converted into serial data inside the ICM/ECM then sent to the speedometer to control the position of the speedometer needle and the liquid crystal (LCD) odometer display. The vehicle speed serial data is also transmitted to the TSM/TSSM for turn signal cancellation.
The odometer mileage is permanently stored and will not be lost when electrical power is turned off or disconnected. The odometer reset switch allows switching between the odome­ter, trip odometer A and trip odometer B displays.
To zero the trip odometer, have the desired trip odometer dis­play visible, press and keep the reset switch depressed. The trip odometer mileage will be displayed for 2-3 seconds and then the trip mileage will return to zero miles.

TACHOMETER THEORY OF OPERATION

The tachometer receives serial data from the ICM/ECM. The tachometer interprets the serial data and converts it into tachometer needle movement.

DIAGNOSTICS

Diagnostic Notes

The reference numbers below correlate with circled numbers on the tachometer diagnostic flow chart.
1. If problems are intermittent, wiggle harness while per­forming tests.
2. Connect BREAKOUT BOX (Part No. HD-42682) and INSTRUMENT HARNESS ADAPTERS (Part No. HD-
46601) between wire harness and tachometer.
3. Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404), black pin probe and patch cord.
The odometer can display six numbers to indicate a maxi­mum of 999999 miles/kilometers. The trip odometers can dis­play six numbers with a tenth of a mile accuracy for a maximum of 99999.9 miles/kilometers.

Job/Time Code Values

SPEEDOMETER PERFORMANCE CHECK 2.6

GENERAL

See Figure 2-18. Use the SPEEDOMETER TESTER (Part No. HD-41354) for speedometer diagnostics. These diagnos­tics may include:
Checking speedometer operation.
Te sting speedometer needle sweeping action.
The tester generates a simulated vehicle speed sensor signal which is sent to the ICM/ECM. The ICM/ECM interprets the signal then sends a message to the speedometer. This signal aids in determining whether speedometer replacement is necessary.
Verifies serial data message to speedometer.
NOTES
Use the following procedures in conjunction with the
manual supplied with the speedometer tester.
Te st results may be inaccurate if tester battery is low.

TESTING

NOTE
The SPEEDOMETER TESTER (Part No. HD-41354) cannot be used to verify the calibration of a speedometer and it will not verify the speedometer’s function to support legal pro­ceedings. It’s purpose is to verify speedometer function when performing service diagnosis or repair. It can also assist in determining if speedometer replacement is necessary.

FUEL GAUGE OPERATION 2.7

THEORY OF OPERATION

With ignition switch ON, the fuel gauge is connected to +12 volts. Current flows through the gauge and variable resistor in the fuel gauge sending unit to ground. The sending unit float controls the amount of resistance in the variable resistor.
Inoperative gauges may be caused by three circumstances.
Sender or fuel gauge not grounded.
Malfunction in sender or fuel gauge.
Broken or disconnected wire from ignition switch to fuel
gauge.
Use the FUEL GAUGE AND SENDER TEST to test suspect components.

FUEL GAUGE AND SENDER TEST

NOTE
Always refer to the applicable wiring diagram (at the rear of this manual) when troubleshooting instruments or gauges.
1. Remove gauge. Ground Y/W wire of fuel gauge sender located at bottom of gauge. Turn ignition switch ON.
a. Fuel gauge must indicate FULL. If gauge indicated
FULL, gauge is functioning correctly. Proceed to step 2.
2. Set MULTI-METER (Part No. HD-35500) to RXI scale to measure the resistance of the sending unit. Place one probe on Y/W and the other probe on a good ground.
FLHT/C/U, FLTR:
If fuel tank is full, the reading should be 7-14 ohms. An empty tank should have a 74-95 ohm resistance. A half full tank will be approximately 30-38 ohms.
FLHR/C/S:
If fuel tank is full, the reading should be 27-40 ohms. An empty tank should have a 240-264 ohm resistance. A half full tank will be approximately 97-118 ohms.
ALL MODELS:
If a very high resistance or infinity is indicated on the meter, the sender may be “open” or not grounded. Check that sender and fuel tank are grounded by placing one probe of Multi-Meter on sender flange and the other probe on crankcase. Meter must indicate one ohm or less. Replace sender if one ohm or less was present. If a higher resistance is present, check for poor connection on ground wire.
3. Check voltage to O/W (+) and BK (-) wire of fuel gauge connector [117] if gauge did not indicate FULL.
a. Correct reading is equivalent to battery voltage.
b. If battery voltage is not present check for broken or
disconnected wire. Replace gauge if wiring problem is not found.
b. If gauge did not indicate FULL, proceed to step 3.

DTC U1016 2.13

GENERAL

Loss of ICM/ECM Serial Data

The serial data connector provides a means for the ignition control module (ICM) or electronic control module (ECM), TSM/TSSM and speedometer to communicate their current status. When all operating parameters on the serial data bus are within specifications, a state of health message is sent between the components. A DTC U1016 indicates that the ICM/ECM is not capable of sending this state of health mes­sage.

DTC U1300, U1301 OR “BUS ER” 2.15

GENERAL

Serial Data Low or Serial data Open/High

See Figure 2-40. The typical serial data voltage range is 0 volts (inactive) to 7 volts (active). Due to the short pulse, volt­ages 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 opera­tions is 0-7.0 volts.

DIAGNOSTICS

Diagnostic Tips

If serial data is shorted, these diagnostic trouble codes
(DTCs) will automatically cause the check engine lamp to illuminate. The odometer will read “Bus Er” in this con­dition.
Diagnostic trouble codes (DTCs) P1009 and P1010 may
accompany DTCs U1300 and U1301.

models, perform diagnostic procedures listed in 4.10
STARTS, THEN STALLS.
If a U1300, U1301 or “BUS Er” is present on EFI models,
perform diagnostic procedures listed in 5.12 STARTS,
