Integrated Control Unit
Circuit Diagram
Description
An integrated control unit, located in lhe left kick panel, integrates the lunctions of the key-in/seat belt r€minder , side
marker light llasher, wiper/washer, lights-on reminder, rear window delogger timer, brake system light bulb check, and
engine oil pressure indicator flasher circuits.
NOTE: Different wires with the same color have been given a nu mber suflix to distinguish them (for example,
GRN/RED I and GRN/RED' are not the same).

Integrated Control Unit
Input Test
Remove the dashboard lower cover and knee bolster,
then disconnect the 15P connector trom the integrated
control unit.
Remove the integrated control unit lrom the under-dach
fuse/relay box.
Inspect the connector and socket terminals to be sure
they are all making good contact.
a lf the terminals are bent, loose or corroded, repair them
as necessary, and recheck the system.
a lf the terminals look OK, make the lollowing input tests
at the connector and under-dash luse/relay box.- ll any test indicates a problem, find and correct the
cause, then recheck the system.
lf all the input tests prove OK, the control unit must
be faulty; replace it.
15P CONNECTOR
NOTE:
a Ditferent wires with the same color have been given
a number suffix to distinguish them (lor example,
GRN/BLU1 and GRN/BLU, are not the same).
a Do not disconnect any connectors on the under-dash
fuse/relay box except the integrated control unit.
