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).

NOTE: Refer to page 23-153 for a diagram of the key-
in reminder circuit, and to page 23-148 for the input test
of the beeper circuit.
When the ignition key is not removed. the key-in reminder
in the integrated control unit senses ground through the
closed ignition key switch. When you open the driver's
door, the beeper circuit senses ground through the closed
door switch. With ground at the "LT BLU" and "GRN/
BLU" terminals, the beeper sounds.
1. Remove the d;shboard lower cover and knee bolster
(see page 23-71).
2. Disconnect the 7P connector from the main wire
narness.
3. Check lor continuity between the No. 2 and No. 4terminals in each condition according to the table.

Engine Oil Pressure
Indicator System
Description
NOTE: Refer to page 23-152 for the circuit diagram ofthe engine oil pressure indicator flasher. and to page 23
156 for the input test of the flasher circuit.
The low engine oil pressure indicator light works in twoways. lt will flash continuously following a momentaryloss ol oil pressure, or it will go on and stay on wath a
complete loss of oil pressure.
When the engine first starts, before oil pressure rises
above 29.4 kPa (O.3 kgf/cmr, 4.3 psi), current flows
through the low engine oil pressure indicator light andthe oil pressure switch to ground. This tests the circuit.
With the engine running, voltage is applied to the Ilash-er circuit of the integrated control unit. With normal oilpressure, the oil pressure switch is open and the low en-gine oil pressure indicator light does not operate. lf the
oil pressure switch closes momentarily (more than O.5
seconds). but then opens again, terminal "YEL/RED" will
sense ground through the switch- The integrated con-trol unit will then provide and remove ground tor the low
engine oil pressure indicator light through terminal"YEL/RED". The light will flash on and off untilthe igni
tion switch is turned to "OFF".
lf engine oil pressure talls below 29.4 kPa (O.3 kgf/cmr,
4.3 psi) and does not increase, the oil pressure switchwill stay closed. The low engine oil pressure indicator light
will go on and stay on.
NOTE: Refer to page 23-130 for the engine oil pressure
switch test.
