FIG. 4: I/O Interface Module

I/O modules accept commands or signals from master

module and activate respective component(s). I/O

module also accepts signals from components outside

cab and forwards them back to master module.

Number of I/O modules used varies depending on

application system.

J2 (gray) pin 1 is 12 volts and pin 12 ground. Power for

pin 1 comes from PDM 1 F9 fuse. Same on J3 plug

(black).

J2 pins 2, 3 and 4 are module identification pins. These

are a combination of grounds and positive voltage pins.

If pins have no wires, they are grounds. (So I/O module

0 would have no wire on pins 2, 3 and 4. Older

machines did have wires on these pins. They were

white 4438 and 4439 wires.)

J2 has inputs on pins 5 through 9. Pins 10 and 11 are

outputs. They have an H-bridge which can be used to

reverse polarity. (Example: open and close a servo).

J3 (black) pin 1 is 12 volts and pin 12 is ground. Pin 2 is

CAN low and pin 3 is CAN high. Pins 4 through 11 are

outputs.

Pins can be checked connector with proper spades for

CAN high and low, power and ground. If there is a

broken wire between J3 connector and a component,

an error code will be displayed.
