SERIAL DATA COMMUNICATION

DESCRIPTION AND OPERATION

TOOL NAME

PART NUMBER

DIGITAL TECHNICIAN II

HD-48650

Serial data communication circuits are used by modules and
diagnostic tools to share information.

The speedometer, ECM, TSM/TSSM/HFSM, radio, ABS and
tachometer (if equipped) all communicate on the serial data
circuit. The serial data circuit is a (LGN/V) wire that runs to all
the modules and is used to transfer data from one module to
the other. This line also runs to the DLC [91] and is used to
communicate with the modules using DIGITAL TECHNICIAN
II (Part No. HD-48650).

DIGITAL TECHNICIAN II

HD-48650

Electronic Control Module (ECM)

See 

Figure 2-14

. The ECM is located under the seat. The ECM

monitors the sensors from the engine and fuel systems in order
to manage the fuel and spark delivery to the motorcycle which
enhances performance and driveability.

Speedometer and Tachometer

The speedometer and tachometer contain part of the indicator
and warning lamps for the motorcycle. They use the serial data
circuit to receive information from the other modules to know
which lamps to illuminate at any given time.

TSM/TSSM/HFSM

See 

Figure 2-15

. The TSM/TSSM/HFSM is located under the

right side cover. It monitors the turn signals switches and con-
trols the turn signals. The clutch and neutral switches are also
inputs to the TSM/TSSM/HFSM. It uses these inputs to
determine when it is safe to allow the motorcycle to start. It
allows starter engagement and sends the information to the

ECM over the serial data circuit letting the ECM know to
activate the fuel injectors. The TSSM/HFSM also controls the
security functions on the motorcycle if equipped with the factory
security system.

Data Link Connector (DLC)

See 

Figure 2-16

. The DLC is located under the left side cover.

The DLC is used to connect the DIGITAL TECHNICIAN II (Part
No. HD-48650) to the motorcycle.

COMMUNICATION DTCS AND "BUS ER"

There are several DTCs that may set due to and issue with
the serial data circuit. Different DTCs are set by different
modules. If a module loses communication it is not able to
generate a DTC. Therefore, the other modules will set DTCs
for that module indicating they are not able to communicate
with it.

Diagnostic Tips

Modules must have power and be grounded in order to com-
municate. Therefore, when checking any communication DTC
be sure to check the power and ground connections on the
suspected module. In some cases "Bus Er" will show on the
odometer.
