Section 05 ELECTRICAL SYSTEM

Subsection 02 (POWER DISTRIBUTION)

FUSE BOX 2 — BUS BAR IDENTIFICATION

1. 12 Vdc from b

attery

2. 12 Vdc from battery

3. CAN LO

4. CAN HI

5. Ground bus-bar

The power relay in FB2 is connected directly to

one of two 12 Vdc bus bars in FB2. When the

START/STOP button is pressed, it completes a

12 Vdc circuit to wake up the ECM, which in turn

completes the power relay ground circuit.

1. Power relay

When th

e power relay closes, it applies 12 Vdc

to a bus

bar located in fuse box 1 (FB1) through

termin

al D6, which in turn distributes power to

the oth

er 12 Vdc bus-bar and the remainder of the

fused

circuits.

Terminal D4 of FB1 then supplies the main ECM

power through a 15 A fuse in FB2.

FUSE BOX 1 — BUS BAR IDENTIFICATION

1. Primary switched power

2. Secondary switched power

If the electrical system is energized and the en-

gine is not started, the ECM will open the power

relay ground circuit to shut off power after ap-

proximately 3 minutes, unless the START button

is pressed again.

When the power relay open, it isolates the bat-

tery from the electrical components, including

the ECM, therefore preventing excessive battery

drain.

The only current drain on the battery when power

is switched off by the ECM is for the GPS in the

information center. It receives power through pin

1 of the information center (not illustrated). This is

used to maintain the GPS memory of the satellite

locations for approximately two hours.

Electrical System Activation

1. Press the START/STOP button to energize the

electrical system.

2. Install the safety lanyard (D.E.S.S. key) on its

post to maintain the Information Center active

when testing procedures require it.

Installing the D.E.S.S. key without pressing the

START/STOP button will not turn on electrical

power.

Pressing the START button without the D.E.S.S.

key installed on its post will turn on electrical

power without starting the engine; the informa-

tion center will cycle through a self-test function

and shut off its display after a few seconds. How-

ever, the electrical system will stay powered up

for approximately three minutes after the START

button was depressed.

NOTE: If the START/STOP button is pressed and

held without the D.E.S.S. key installed, the infor-

mation center will stay on as long as the START

button is held without cranking the engine.
