2. Connect the red tester lead to the red/blue wire; then
connect the black tester lead to the black wire.
3. With the brake applied, the meter must show battery
voltage.

NOTE: If the meter shows no voltage, inspect the 10
amp ignition (IGN) fuse, brakelight switch, wiring
harness, or connectors.
Power Distribution Module
(PDM)

NOTE: The module and wiring harness are not a
serviceable component and must be replaced as an
assembly.
If there is any type of electrical system failure, always
check the fuses first.

NOTE: The fuses are located in a power distribu-
tion module under the left side of the dash.
1. Remove all fuses from the power distribution module.
 NOTE: To remove a fuse, compress the locking tabs
on either side of the fuse case and lift out.
4411-141

NOTE: Make sure the fuses are returned to their
proper position according to amperage. Refer to the
amperage listed under each fuse on the power distri-
bution module.
2. Set the meter selector to the DC Voltage position.
3. Connect the black tester lead to battery ground.
4. Using the red tester lead, contact each end of the fuse
holder connector terminals individually.
5. The meter must show battery voltage from one side
of the connector terminal ends.

NOTE: Battery voltage will be indicated from only
one side of the fuse holder connector terminal; the
other side will show no voltage.

NOTE: When testing the HI fuse holder, the head-
light OFF/HI/LO switch must be in the HI position;
when testing the LIGHTS fuse holder, the headlight
dimmer switch can be in either the HI or the LO posi-
tion.

NOTE: If the meter shows no battery voltage, trou-
bleshoot the battery, switches, power distribution
module, or the main wiring harness.
RELAYS
The 4-pin relays are identical plug-in type located on the
power distribution module. Relay function can be
checked by switching relay positions. The 4-pin relays
are interchangeable.
EFI Sensors/Components
FUEL INJECTOR
Voltage
Remove the connector from the fuel injector. Place the
red meter lead to the orange wire and black meter lead to
ground. With the ignition switch in the on position the
meter must read battery voltage.
Resistance
With the connector still removed from the injector, place
the red meter lead to either terminal; then connect the
black tester lead to the other terminal. Reading is typi-
cally 9.78-10.82 ohms (700) or 12 ohms (500).
 NOTE: If voltage is not present, troubleshoot the
battery, connector pins, wiring harness, fuses, or
relay. If resistance is not present or largely out of
specification, replace the injector.
CRANKSHAFT POSITION (CKP)
SENSOR
Resistance
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to the brown wire; then
connect the black tester lead to the white wire. The
meter reading must be 104-156 ohms.
AC Voltage

NOTE: The battery must be at full charge for these
tests.
1. Set the meter selector to the AC Voltage position.
2. Connect the red tester lead to the brown wire; then
connect the black tester lead to the white wire.
3. Crank the engine over using the electric starter.
4. The meter reading must be 2.0 volts or more.
CAUTION
Always replace a blown fuse with a fuse of the same
type and rating.
Component data can be tested using the CATT II. Utilize
the Test screen.
