ACURA INTEGRA 1998 Service Repair Manual

- How The Circuit Wo
With the ignition switch ON (ll), voltage is applied
through fuse 24 to the coil of the moonroof relay.
The moonroof relay energizes and voltage is
applied from fuse 49 through the closed contacts of
the moonroof relay to the moonroof switch.
Open Operation
When you push the moonroof switch to the OPEN
position, voltage is applied to the moonroof motor.
The moonroot motor is grounded through the
CLOSE contacts of the moonroof switch, and the
motor runs to open the moonroof
Close Operation
When you push moonroof switch to the CLOSE
position, voltage is applied to the moonroof motor.
The moontoof motor is grounded through the OPEN
contacts of the moonroof switch, and the motor runs
to close the moonroof.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

- How the Circuit Works
The immobilizer system is designed to prevent the
car f rom being started without the owner's ignition
key. lf an attempt is made to start the car without
the correct key, the immobilizer system will disable
the car's fuel supply.
The immobilizer system consists of the ignition key,
immobilizer receiver unit, immobilizer indicator
light, PGM-FI main relay, fuel pump, and the PCM
or ECM.
With the ignition switch in ON (ll) or START (lll), the
immobilizer receiver unit and the PCM or ECM
receive an "ignition on" signal through fuse 44 and
the PGM-FI main relay. The PCM or ECM then
sends power to the ignition key transponder through
the immobilizer receiver unit. The transponder then
sends a coded signal back to the PCM or ECM
through the receiver unit. lf the signal is correct, the
PCM or ECM will energize the car's fuel supply
system by grounding the PGM-FI main relay. The
immobilizer indicator light flashes a code to indicate
that the correct key has been inserted. lf the
ignition key signal is not correct, the PCM or ECM
will not energize the car's fuel supply system by not
grounding the PGM-Fl main relay. The immobilizer
indicator light then flashes a code to indicate that an
incorrect key has been inserted.
Refer to the Service Manual (Section 23,
Body Electrical) for specific tests and
troubleshooting procedures.
