These components form two separate circuits. A
high amperage circuit that feeds the starter motor up
to 300+ amps, and a control circuit that operates on
less than 20 amps.
The Powertrain Control Module (PCM) controls a
double start over ride safety that does not allow thestarter to be engaged if the engine is already run-
ning.
SUPPLY CIRCUIT AND CONTROL CIRCUIT
The starter system consists of two separate cir-
cuits:
²A high amperage supply to feed the starter
motor.

(7) Connect a starter switch or a jumper wire
between the remote battery positive post and termi-
nal 87 of the starter relay connector.
(a) If engine cranks, starter motor and starter
solenoid is good. Go to the Starter Relay Test.(b) If engine does not crank or solenoid chatters,
check wiring and connectors from starter relay to
starter solenoid for loose or corroded connections.
Check for corroded connections at starter termi-
nals.
(c) Repeat test. If engine still fails to crank prop-
erly, trouble is within starter or starter mounted
solenoid, and replace starter.
STARTER RELAY
WARNING: CHECK TO ENSURE THAT THE TRANS-
MISSION IS IN THE PARK POSITION WITH THE
PARKING BRAKE APPLIED.
RELAY TEST
The starter relay is located in the Power Distribu-
tion Center (PDC) in the engine compartment. Refer
to the PDC label for relay identification and location.
Use the Starter Relay Pin Call-Out table and (Fig. 3)
for relay testing.
Remove the starter relay from the PDC as
described in this group to perform the following tests:
(1) A relay in the de-energized position should
have continuity between terminals 87A and 30, and
no continuity between terminals 87 and 30. If OK, go
to Step 2. If not OK, replace the faulty relay.
(2) Resistance between terminals 85 and 86 (elec-
tromagnet) should be 7565 ohms. If OK, go to Step
3. If not OK, replace the faulty relay.
(3) Connect a battery B+ lead to terminals 86 and
a ground lead to terminal 85 to energize the relay.
The relay should click. Test for continuity between
terminals 30 and 87, and no continuity between ter-
minals 87A and 30. If OK, refer to Relay Circuit Test
procedure. If not OK, replace the faulty relay.

RELAY CIRCUIT TEST
(1) The relay common feed terminal cavity (30) is
connected to battery voltage and should be hot at all
times. If OK, go to Step 2. If not OK, repair the open
circuit to the PDC fuse as required.
(2) The relay normally closed terminal (87A) is
connected to terminal 30 in the de-energized position,
but is not used for this application. Go to Step 3.
(3) The relay normally open terminal (87) is con-
nected to the common feed terminal (30) in the ener-
gized position. This terminal supplies battery voltage
to the starter solenoid field coils. There should be
continuity between the cavity for relay terminal 87
and the starter solenoid terminal at all times. If OK,
go to Step 4. If not OK, repair the open circuit to the
starter solenoid as required.
(4) The coil battery terminal (86) is connected to
the electromagnet in the relay. It is energized when
the ignition switch is held in the START position. On
vehicles with a manual transmission, the clutch
pedal must be fully depressed for this test. Check for
battery voltage at the cavity for relay terminal 86
with the ignition switch in the START position, and
no voltage when the ignition switch is released to the
ON position. If OK, go to Step 5. If not OK with an
automatic transmission, check for an open or short
circuit to the ignition switch and repair, if required.
If the circuit to the ignition switch is OK, see the
Ignition Switch Test procedure in this group. If not
OK with a manual transmission, check the circuit
between the relay and the clutch interlock/upstop
switch for an open or a short circuit. If the circuit is
OK, refer to the Clutch Interlock/Upstop Switch
Diagnosis and Testing in Group 6-Clutch.
(5) The coil ground terminal (85) is connected to
the electromagnet in the relay. It is grounded
through the PCM only when the gearshift selector
lever is in the Park or Neutral positions. On vehicles
with a manual transmission, it is grounded through
the PCM when the clutch pedal is depressed. Check
for continuity to ground at the cavity for relay termi-
nal 85. If not OK, check for an open or short circuit
to the park/neutral starting and back-up lamp
switch, or the clutch interlock/upstop switch. Repair,
as necessary. If the circuit is OK, refer to the Park/Neutral Starting and Back-Up Lamp Switch Removal
and Installation in Group 21-Transaxle. Testing is

different status messages may be displayed as fol-
lows:
²ªProgramming Successfulº is displayed if SKIM
Sentry Key programming succeeds.
²ªLearned Key in Ignitionº is displayed if the key
in the ignition has already been programmed into
that vehicle's SKIM.
²ª8 Keys Already Learned (At The Maximum)
Programming Not Doneº is displayed if eight keys
have already been programmed into the SKIM. In
this case, if a new key needs to be added due to a
lost or defective key, the ªErase All Keysº function
(requires entering secured access mode) has to be
performed. Then the customer is seven keys plus the
new key MUST be reprogrammed into the SKIM.
²ªProgramming Not Attemptedº is displayed after
an ªErase All Keysº function is executed.
²ªProgramming Key Failedº is displayed if fur-
ther diagnosis is required.
²To learn additional keys, turn the ignition OFF,
