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).

Lighting System
Daytime Running Lights Control Unit Input Test (Ganada)
Remove the dashboard lower cover and knee bolster.
Disconnect the connectors from the daytime running
lights control unit.
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 ll the terminals look OK. make the lollowing in-
put tests at the connector.
lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.
lf all the input tests prove OK, the control unit
must be faulty; replace it.
