SERIAL DATA BUS DIAGNOSTICS

DESCRIPTION AND OPERATION

There are two serial data busses. The first is the J1850 serial
data bus which communicates between the radio and the ECM,
TSSM and instruments. Refer to

Table 8-34

. The second serial

data bus is the Infotainment bus, which uses a CAN protocol
to communicate between the radio and the other radio
accessories. Refer to

Table 8-35

. The radio captures any errors

found on both serial data busses and stores them as DTCs.

Loss of Serial Data: DTC U1016

The serial data connector provides a means for the 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. DTC U1016 indicates that the ECM
is incapable of sending this state of health message.

Starts then Stalls: DTC U1300, U1301

The typical serial data voltage range is 0 (inactive) to 7V
(active). Due to the short pulse, voltages will be much lower
on a multimeter. In analog mode, a multimeter reading serial
data will show continuous voltage when active, typically 0.6-
0.8V. The range for acceptable operations is greater than 0
and less than 7V.

NOTE

Problems in the fuel system or idle air control system may also
create this symptom. If this symptom is present, see

before proceeding.

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.

•

If radio ground and antenna ground are open, a serial data
BUS fault may occur causing a start and stall condition.

•

The amplifier fuse is an inline fuse for all accessory
installations and is mounted in the fuse block.

1. Speed Pulse Availability Test

Turn IGN ON and engine stop switch to RUN.

Enter radio diagnostics.

Rotate rear wheel.

Are speed pulses on radio display greater than 0?

Yes. Install BREAKOUT BOX (Part No. HD-47918)
to radio harness [27] and perform wiggle test. Repair
intermittent on (LGN/V) wire if necessary. (6130)

No.

2. Serial Data Continuity Test

Install radio BREAKOUT BOX (Part No. HD-47918) to
radio harness [27], leaving radio [27A] disconnected, and
ECM BREAKOUT BOX (Part No. HD-48637) to ECM
harness [78], leaving ECM [78A] disconnected.

Test for continuity between radio breakout box terminal 9
and ECM breakout box terminal 69.

Does continuity exist?

Yes. Perform

if DTC

U1016 has been set. If DTC U1016 is not present,
replace ECM. See the service manual. (6123)

No. Repair open on (LGN/V) wire. (5041)

FACTORY DEFAULTS

If a symptom is present without a DTC, restoring ROM defaults
to the factory settings may resolve the issue, which can
sometimes be caused by a unique sequence of rider interac-
tions with the system.

NOTE

On FLHTCU, FLHTK, FLTRU models, set Intercom, VOX and
CB squelch to midpoint and turn Weather Alert to OFF.

Access the radio diagnostic display and press softkey 1
(DEFAULT), or proceed as follows:

8-30 2011 Touring Diagnostics: Audio System

Turn IGN ON with the radio OFF.

Push and hold softkeys 1 and 3 and OK simultaneously
for 2 seconds.

Push the arrow up 2 times.

Push softkey 2.

Turn IGN OFF for more than 20 seconds.

Turn ignition on and verify all defaults have reset.

The following are reset to the factory ROM defaults:

•

Radio presets.

•

Volume levels, bass, treble, AVC, fader and VOX.

•

Display contrast.

•

External amplifier present is reset to no amplifier (if an
external amplifier is present, it will take two long ignition
cycles before the radio is set up to enable the external
amplifier).

•

CB or PHONE present is reset to no phone (this is used
by the radio to enable the intercom setting if a CB or phone
are present, and like the amplifier, it will take two long
ignition cycles before the radio completely enables the
intercom).

•

All DTCs are reset.

•

Navigation saved data. This data is immediately updated
upon navigation startup, so the user should be unaffected.

DIAGNOSTICS

TOOL NAME

PART NUMBER

SWR METER ADAPTERS

HD-48037

Before proceeding with the diagnostics, make sure the radio
is calibrated, any CD has been removed from the CD player
and reset factory defaults. Doing so can reduce or eliminate
needless troubleshooting of these symptoms.

If a CD is stuck in the player, the player must be reset. Remove
the main fuse and wait 5 minutes and then install fuse. Turn

radio power ON and press the EJECT button. If the CD does
not eject after performing the reset procedure, the radio is faulty
and must be replaced.

Diagnostic Tips

Reading and understanding these diagnostic tips will help make
troubleshooting symptomatic problems easier.

If radio is uncalibrated, CB is not functional. If the CB is
not allowed in a region (Japan, for example), then the unit
will not operate.

To use the dummy load, screw the lamp onto the antenna
jack of the CB using the appropriate SWR METER
ADAPTERS (Part No. HD-48037). Press the PTT switch.
If the CB is transmitting a carrier wave, the lamp should
illuminate. Speaking into the microphone should cause
the lamp to flicker. It should get brighter and dimmer
depending on how loud your voice is. A change in lamp
brilliance means the CB is modulating.

The amplifier fuse is an inline fuse for all accessory
installations and is mounted in the fuse block.

It is possible to have a fault on more than one handlebar
control as a result of the following configuration:

•

Terminal 5 (V/BK) wire is common to both the PTT/
Squelch and Mode handlebar controls.

•

Terminal 8 (BN/BK) wire is common to both the PTT/
Squelch and Audio handlebar controls.

•

Terminal 22 (GY/GN) wire is common to both the
PTT/Squelch and Audio handlebar controls.

Terminal 3 (PK/W) wire is common to both the Mode and
Audio handlebar controls. Therefore, it is possible to have
a fault on more than one handlebar control as a result of
this configuration.

Some aftermarket exhaust systems may cause excessive
pressure on the rear mounts causing the exhaust system
to be put into a bind creating excessive vibration the CD
player may not be able to isolate.
