ON-VEHICLE TESTING
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
DISABLING/ENABLING IGNITION & FUEL SYSTEMS
WARNING: To prevent engine from starting while performing tests,
always disable ignition and fuel systems.
Disabling Ignition & Fuel Systems
Remove Automatic Shutdown Relay (ASD) located in Power
Distribution Center (PDC). Refer to PDC cover for proper relay
location. PDC is located in engine compartment. On 5.9L diesel
engines, also disconnect fuel shutdown solenoid connector. Solenoid is
located behind upper intake manifold. See appropriate SYSTEM &
COMPONENT TESTING article in ENGINE PERFORMANCE section.
Enabling Ignition & Fuel Systems
When testing and/or repairs have been completed, verify
battery condition. Recharge battery as necessary, after starter tests
have been completed. Disconnect all test equipment. Install ASD relay.
On 5.9L diesel engines, reconnect fuel shutdown relay connector. On
all models, start engine several times to verify malfunction has been
corrected.
CRANKING TEST
NOTE: Ensure engine is at normal operating temperature. High
viscosity oil, extreme cold temperatures, or tight engine
will increase amperage draw.
1) Using a battery load tester, connect positive and negative
leads to battery. Connect inductive ammeter pick-up to positive
battery cable. Disable ignition and fuel systems. See
DISABLING/ENABLING IGNITION & FUEL SYSTEMS.
2) Ensure all lights and accessories are off. Place A/T in
Park position or M/T in Neutral position. Apply parking brake. Crank
engine and observe voltmeter reading. If voltage is more than 9.6
volts and cranking amperage draw is more than specified amps, proceed
to CIRCUIT RESISTANCE TESTS. See STARTER SPECIFICATIONS - CARS or
STARTER SPECIFICATIONS - TRUCKS.
3) If voltage is 12.5 volts or more and cranking amperage
draw is less than specified, check starter circuit components in the
following order:
starter solenoid, starter relay, starter relay circuit, park/neutral
position switch or transmission range sensor (A/T), clutch pedal
position switch (M/T), ignition switch, wiring harness and
connections.
CIRCUIT RESISTANCE TESTS
NOTE: If excessive resistance is not found in circuits being
tested, remove starter and proceed to BENCH TESTING.
Battery Connection Resistance Test
1) Disable vehicle ignition and fuel systems. See
DISABLING/ENABLING IGNITION & FUEL SYSTEMS. A voltmeter accurate to
one tenth of a volt will be needed for the following tests.

2) Connect voltmeter positive lead to negative battery cable
clamp. Connect voltmeter negative lead to negative battery post. Crank
engine and observe voltmeter reading. If voltage is detected, repair
poor contact between cable clamp and post. Perform same procedure to
positive battery post and cable clamp.
Ground Connection Resistance Test
Connect voltmeter negative lead to negative battery post.
Connect voltmeter positive lead to engine block, near negative battery
cable grounding point. Crank engine and observe voltmeter reading. If
voltmeter reading indicates more than 0.2 volt, repair poor ground
connection or replace ground cable.
Starter Ground Connection Resistance Test
Connect voltmeter negative lead to negative battery post.
Connect voltmeter positive lead to starter housing. Crank engine and
observe voltmeter reading. If voltmeter reading indicates more than 0.
2 volt, repair poor starter-to-ground connection.
Positive Battery Cable Resistance Test
1) Remove starter heat shield (if equipped) to gain access t\
o
starter solenoid connections. Connect voltmeter negative lead to
starter solenoid battery terminal and voltmeter positive lead to
positive battery post.
2) Crank engine and observe voltmeter reading. If voltage
reads more than 0.2 volt, correct poor connection between battery
cable and starter solenoid or replace positive battery cable.
SOLENOID CIRCUIT TEST
NOTE: Perform SOLENOID CIRCUIT TEST before testing starter relay
and starter relay circuit. Ensure A/T is in Park position or
M/T is in Neutral position and parking brake is applied.
1) Disable vehicle ignition and fuel systems. See
DISABLING/ENABLING IGNITION & FUEL SYSTEMS.
2) Ensure battery is fully charged. Ensure solenoid
connections are not loose or corroded. Remove starter relay from Power
Distribution Center (PDC). Refer to PDC cover for proper relay
location. PDC is located in engine compartment.
3) Connect a remote starter switch or jumper wire between
starter relay socket terminal No. 87 and positive battery post. See
Fig. 1 or 2. If engine cranks, solenoid and starter are good. Go to
STARTER RELAY TEST.
4) If engine fails to crank, or if solenoid chatters, check
wiring and connectors from starter relay socket to starter solenoid
terminal. Repair any loose or corroded connections. If engine still
fails to crank, remove starter and proceed to SOLENOID TEST under
BENCH TESTING.
STARTER RELAY TEST
NOTE: Perform SOLENOID CIRCUIT TEST before testing starter relay.
Remove starter relay from Power Distribution Center (PDC).
Refer to PDC cover for proper relay location. PDC is located in engine
compartment. Connect 12-volt power source to starter relay terminal
No. 86 and ground terminal No. 85. See Fig. 1 or 2. Using ohmmeter,
check continuity across starter relay terminals No. 30 and 87. If
continuity is not present, replace starter relay.

STARTER RELAY CIRCUIT TEST
NOTE: Perform STARTER RELAY TEST before testing starter relay
circuit.
1) Ensure battery is fully charged. Remove starter relay from
Power Distribution Center (PDC). Refer to PDC cover for proper relay
location. PDC is located in engine compartment.
2) Connect a jumper wire between starter relay socket
terminal No. 30 and terminal No. 87. See Fig. 1 or 2. If engine does
not crank, go to SOLENOID TEST under BENCH TESTING. If engine cranks,
go to next step.
3) Turn ignition on. Check voltage between ground and starter
relay socket terminal No. 30. If battery voltage is not present,
repair open in circuit between starter relay socket and battery. If
battery voltage is present, go to next step.
4) Check voltage between ground and starter relay socket
terminal No. 86 with ignition switch in START position and clutch
pedal depressed (if equipped with M/T). If battery voltage is present,\
circuit is okay. Go to step 6) if equipped with M/T or step 7) if
equipped with A/T. If battery voltage is not present, repair open in
circuit between ignition switch and starter relay socket (A/T) or go
to next step (M/T).
5) Unplug wiring connector from clutch position switch
mounted on clutch pedal bracket. Connect jumper wire between clutch
position switch connector terminals. Recheck for voltage at starter
relay socket terminal No. 86 with ignition switch in START position.
If battery voltage is present, check clutch position switch adjustment
(if applicable). Adjust switch as necessary. If switch adjustment is
okay, check clutch position switch. See CLUTCH POSITION SWITCH TEST.
If battery voltage is not present, repair wiring between ignition
switch and starter relay socket as necessary.
6) On M/T models, connect voltmeter negative lead to starter
relay socket terminal No. 85 and positive lead to terminal No. 86.
Turn ignition switch to START position and depress clutch pedal. If
battery voltage is present, starter relay socket ground circuit is
good. Replace faulty starter relay. If battery voltage is not present,
repair ground wire circuit.
7) On A/T models, connect voltmeter negative lead to starter
relay socket terminal No. 85 and positive lead to terminal No. 86.
Ensure transmission gear selector is in Park or Neutral position.
Ground circuit runs through Park/Neutral Position (PNP) switch or
Transmission Range (TR) sensor on transmission. Turn ignition switch
to START position. If battery voltage is present, starter relay socket
ground circuit is good. Replace faulty starter relay.
8) If battery voltage is not present, check PNP switch or TR
sensor for loose or damaged connections. Also, check ground to PNP
switch or TR sensor. Repair as necessary. If connections and ground
are okay, check PNP switch or TR sensor. See PARK/NEUTRAL POSITION
(PNP) SWITCH & TRANSMISSION RANGE (TR) SENSOR TEST.
