COMMUNICATING ECM
MOTOR COMMUNICATIONS
(CONTROL) CONNECTION
(J10) (see Fig 58)
This connector sends and receives
messages to and from the blower motor
through a single peer-to-peer network.
The blower motor does not communi-
cate on the same communications buss
as the furnace, condenser and thermo-
stat. Further, a different communica-
tions protocol is used.
For troubleshooting purposes, follow
the wiring diagram and troubleshooting
flowchart supplied in this manual and
on the inside of the furnace blower
door. Additionally, the pin designations
for the connector are specified below:
Pin 1 to communicating blower
motor connector Pin 1 (+V)
Pin 2 to communicating blower
motor connector Pin 2 (TX)
Pin 3 to communicating blower
motor connector Pin 3 (RX)
Pin 4 to communicating blower
motor connector Pin 4 (C)
