1998 ACURA INTEGRA Service Repair Manual

- How the Circuit Works
The security system control unit has a 3 position
switch: Manual. Auto. and Auto Lock. Here's what
happens when you arm the system, regardless ol
the switch position:
o The parking lights will flash once.
. The security indicator will flash once per second
after the system is armed.
With the switch in the Manual position, the security
system can only be armed by using the remote
control transmitter, After you remove the key from
the ignition and close all doors, the hood (if
equipped with the optional hood switch), the hatch
or trunk. Dress the lock button on the transmitter
and the system will arm (if the system is in the beep
sound mode, the horn will sound once). The doors
will automatically lock when the system is armed.
With the switch in the Auto position, the security
system will arm itself within about 20 seconds after
you turn the engine off, remove the key from the
ignition, and close the halch or trunk, the hood (if
equipped with the optional hood switch), or last
door. lf a door is opened during the 2o-second exit
delay time, the timer will reset itself . The remote
control transmitler can still be used to arm the
system with the switch in Auto position (see manual
for details).
With the switch in Auto Lock position, the security
system will arm itself and lock the doors about 20
seconds after you turn the engine of{, remove the
key from the ignition, and close the hatch or trunk,
the hood (if equipped with the optional hood
switch), or last door. lf a door is opened during the
2o-second exit delay time, the timer will reset. The
remote control transmitter can still be used to arm
the system in the Auto Lock position.
Triggering the Alarm
After the security system is armed, the sound ot
breaking glass or the opening of a door, hood,
hatch or trunk will trigger the alarm, and cause
the following:
r The horn will sound for30 seconds.
The optional siren will sound lor 60 seconds.
. The parking lights will flash.
. The security indicator LED will flash twice per
second.
. The starter will be disabled.
At the end of the alarm cycle, the system will
automatically rearm.
Disarming the Security System
There are two ways to disarm the security system:
. With the transmitter
o With the disarm/valet switch
When the system is disarmed, regardless of the
method used, the parking lights will flash two times if
the alarm has not been triggered and three times if
the alarm has been triggered. To disarm the system
with the transmitter, press the unlock button (if the
system is in the beep sound mode, the horn will
sound two times if the alarm has not been triggered,
however, will sound three times if the alarm has
been triggered). The driver's door will unlock
(pressing the unlock button twice will unlock all
doors).
To disarm the security system using the
disarm/valet switch, enter the car and turn the
ignition switch to ON (ll) then press the disarm/valet
switch button. lf you open the door when the control
unit switch is in Auto or Auto Lock, a 2o-second
entry delay will give you time to disarm the system.
However, when the system is armed by the
transmitter, the entry delay time is changed to zero
seconds, and the alarm is triggered as soon as you
oDen the door.
ldentifying Tripped Sensors
The system will indicate the sensor which triggered
the alarm through the security indicator LED. While
sitting inside the vehicle wlth the key out of the
ignition switch, all doors, the hood (if equipped with
the optional hood swilch), the hatch or trunk must be
closed. Press and hold the disarm/valet switch.
Press the lock button and then the unlock button of
the transmitter. Belease the disarm/valet switch. The
status LED will blink according to the following code:
Sensors
Door
Trunk/Hatch
System Switches
Glass Breakage
Hood (Optional)
Number ol Flashes
1 blink, pause, repeat
2 blinks, pause, repeat
3 blinks, pause, repeat
4 blinks, pause, repeat
5 blinks, pause, repeat
For further operating instructions and troubleshooting,
see the security system owner's manual.

lnterlock System
- How the Circuit Works
Key Interlock
Battery voltage is supplied at all times through f use
33 to the key interlock switch. When the key is in
the ignition, battery voltage is supplied to the key
intedock solenoid and the key interlock circuit in the
interlock control unit. When the A/T gear position
switch is in PABK, ground is provided to the key
interlock circuit. This removes ground from the
interlock solenoid, the solenoid is deenergized, and
the key can be removed from the ignition.
Shift Position Interlock
Battery voltage is supplied at all times lrom fuse 52
to the brake switch. With the ignition in ON (ll) or
START (lll), battery voltage is supplied through luse
25 to the shift lock solenoid. When you push the
brake pedal, battery voltage is applied through the
GRN/VVHT wire to the transmission ('98-99 models)
or powertrain ('00 model) control module (TCM or
PCM). lf, at the same time, you do not push the
accelerator pedal, a low voltage signal is sent
through the RED/BLK wire to the TCM or PCM. The
TCM or PCM then applies voltage through the
WHT/RED wire to the shift lock circuit in the
interlock control unit. lf the A,/T gear position switch
is in the PARK position, the shift lock circuit
provides ground to the shift lock solenoid. The
solenoid is then energized, and the shift lever can
be moved from the PARK Dosition.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

Power Mirrors
- How the Gircuit Works
The two outside mirrors are controlled by the power
minor switch. Each mirror has two reversible
motors: one motor moves the mirror uo and down
and the other motor moves the mirror left and right.
The oower mirror switch contains three switches lo
control mirror direction, and two switches to select
the left or right mirror. With the ignition in ON (ll),
battery voltage is supplied to the power mirror
switch. The mirror selector switch directs voltage
from two of the direction switches to either the left
or the right minor. Each direction switch is used for
more than one function.
Mirror Up Operation
With the power mirror switch in the up position,
switch 1 is moved to the A oosition. Switch 1
applies battery voltage to both the left and right
power mirror up/down motors. lf the mirror selector
switch is in the left position, the left up/down motor
is grounded through the mirror selector switch and
switch 2 in the B position to G501 (Sedan) or G502
(Hatchback). lf the right mirror up/down motor is
selected il is also grounded through switch 2 in the
B position.
Mirror Down Operation
With the power mirror switch in the down position,
switches 2 and 3 are moved to the A position.
Switch 2 applies battery voltage to the left or right
power mirror up/down motor as determined by the
mirror selector switch. The selected mirror motor is
grounded through switch I in the B position to G501
(Sedan) or G502 (Hatchback). When switch 2 is
moved to position A, it also applies battery voltage
to the selected mirror lefyright motor. With switch 3
in the A position, battery voltage is supplied to both
sides of the leruright motor so it does not move.
Mirror Left Operation
With the power mirror switch in the left position,
switches 1 and ? ate moved to the A oosition.
Switch 2 applies battery voltage to the left or right
power mirror lefvright motor as determined by the
mirror selector switch. The selected mirror motor is
grounded through switch 3 in the B position to G501
(Sedan) or G502 (Hatchback). When switch 2 is
moved to position A, it also applies battery voltage
to the selected mirror up/down molor. With switch 1
in the A position, battery voltage is supplied to both
sides of the uD/down motor so it does not move.
Mirror Right Operation
With the power mirror switch in the right position,
switch 3 is moved to the A position. Switch 3
applies battery voltage through the mirror selector
switch to the left or right lefvright motor. The
motor is grounded through the mirror selector
switch and switch 2 in the B oosition to G501
(Sedan) or G502 (Hatchback).
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
