POWER DISTRIBUTION SYSTEMS
ACCESSORY RELAY
DESCRIPTION
The accessory relay is an electromechanical device
that switches fused battery current to the accessory
powered vehicle circuits when the ignition switch is
turned to the Accessory or On positions. The delay
feature will maintain power to the accessories for 45
seconds after the ignition is shut off or until a door is
opened. This allows sufficient time to close windows
and park the windshield wipers. The accessory relay
is located in the Integrated Power Module (IPM) in
the engine compartment.
The accessory relay is a International Standards
Organization (ISO) relay. Relays conforming to the
ISO specifications have common physical dimensions,
current capacities, terminal patterns, and terminal
functions.
The accessory relay cannot be repaired or adjusted
and, if faulty or damaged, it must be replaced.
OPERATION
The ISO relay consists of an electromagnetic coil, a
resistor or diode, and three (two fixed and one movable)
electrical contacts. The movable (common feed) relay
contact is held against one of the fixed contacts (normal-
ly closed) by spring pressure. When the electromagnetic
coil is energized, it draws the movable contact away
from the normally closed fixed contact, and holds it
against the other (normally open) fixed contact.
When the electromagnetic coil is de-energized,
spring pressure returns the movable contact to the
normally closed position. The resistor or diode is con-
nected in parallel with the electromagnetic coil in the
relay, and helps to dissipate voltage spikes that are
produced when the coil is de-energized.
DIAGNOSIS AND TESTING
DIAGNOSIS & TESTING - ACCESSORY RELAY
The accessory relay (Fig. 1) is located in the Inte-
grated Power Module (IPM), in the engine compart-
ment. For complete circuit diagrams, refer toWiring
Diagrams.
(1) Remove the accessory relay from the IPM.
Refer toAccessory Relayin the Removal and
Installation section of this group for the procedure.
(2) 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 3. If not OK, replace the faulty relay.
(3) Resistance between terminals 85 and 86 (elec-
tromagnet) should be 75   5 ohms. If OK, go to Step
4. If not OK, replace the faulty relay.
(4) Connect a battery to terminals 85 and 86.
There should now be continuity between terminals
30 and 87, and no continuity between terminals 87A
and 30. If OK, perform the Relay Circuit Test that
follows. If not OK, replace the faulty relay.
DIAGNOSIS & TESTING - RELAY CIRCUIT TEST
(1) The relay common feed terminal cavity (30) of
the IPM is connected to battery voltage and should
be hot at all times. Check for battery voltage at the
fused B(+) circuit cavity in the IPM receptacle for the
accessory relay. If OK, go to Step 2. If not OK, repair
the fused B(+) circuit to the IPM 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 fused B(+) fuse in the IPM that feeds the
accessories when the relay is energized by the igni-
tion switch. There should be continuity between the
IPM cavity for relay terminal 87 and the fused B(+)
fuse in the IPM at all times. If OK, go to Step 4. If
not OK, repair the open fused B(+) circuit to the IPM
fuse as required.

(4) The coil ground terminal (85) is connected to
the electromagnet in the relay. It receives battery
feed to energize the accessory relay when the ignition
switch is in the Accessory or On positions. Turn the
ignition switch to the On position. Check for battery
voltage at the fused ignition switch output (acc/run)
circuit cavity for relay terminal 85 in the IPM recep-
tacle for the accessory relay. If OK, go to Step 5. If
not OK, repair the open fused ignition switch output
(acc/run) circuit to the ignition switch as required.
(5) The coil battery terminal (86) is connected to
the electromagnet in the relay. The IPM cavity for
this terminal should have continuity to ground at all
times. If not OK, repair the open ground circuit to
ground as required.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the Integrated Power Module (IPM)
cover from the IPM.
(3) Remove the accessory relay from the IPM.
Refer to the IPM cover for relay location.
INSTALLATION
(1) Position the accessory relay in the proper
receptacle in the Integrated Power Module (IPM).
(2) Push in firmly on the accessory relay until the
terminals are fully seated in the terminal cavities in
the IPM receptacle.
(3) Install the IPM cover.
(4) Reconnect the battery negative cable.
INTEGRATED POWER MODULE
DESCRIPTION
The Integrated Power Module (IPM) is a combina-
tion of the Power Distribution Center (PDC) and the
Front Control Module (FCM). The IPM is located in
the engine compartment, next to the battery on this
model (Fig. 2). The power distribution center mates
directly with the Front Control Module (FCM) to
form the IPM Fuse and Relay Center. The power dis-
tribution center (PDC) is a printed circuit board
based module that contains fuses and relays, while
the front control module contains the electronics con-
trolling the IPM and other functions. This IPM con-
nects directly to the battery positive via a four pin
connector. The ground connection is via two other
connectors. The IPM provides the primary means of
voltage distribution and protection for the entire
vehicle.
The molded plastic IPM housing includes a base
and cover. The IPM cover is easily opened or removed
for service access by squeezing the two marked coverlatches and has a fuse and relay layout map integral
to the inside surface of the cover. This IPM housing
base and cover are secured in place by an IPM
mounting bracket. This mounting bracket is designed
to allow the IPM to rotate counter-clockwise once the
locking tab is disengaged. The IPM mounting bracket
is secured in place by bolts threaded into the left
front wheel house.
Replaceable components of the IPM assembly are
broken down into the following components: the
Power Distribution Center (PDC) (without fuses or
relays), the IPM cover, the Front Control Module
(FCM), the IPM mounting bracket, IPM bracket
retaining clips and the IPM assembly which includes
the power distribution center, the cover and FCM.
Refer to the Front Control Module in the Elec-
tronic Control Module sectionof this service
manual for information on the FCM.
OPERATION
All of the current from the battery and the gener-
ator output enters the Integrated Power Module
(IPM) via a four- pin connector on the bottom of the
module. The IPM cover is unlatched and opened or
removed to access the fuses or relays. Internal con-
nections of all of the power distribution center cir-
cuits is accomplished by a combination of bus bars
and a printed circuit board. Refer to the Wiring sec-
