SRS components are located in this area. Reviewthe SRS component locations (see page 23-'13) and precautions andprocedures (see page 23-14) in the SRS section before performing repairs or service.
1. Disconnect the 14P connector from the control unit.
2. Inspect the connector and socket terminals to be sure they are all making good contact.
. lf the terminals are bent, loose, orcorroded, repairthem as necessary, and recheckthe system.. lf the terminals look OK, go to step 3.

lf any test indicates a problem, find and correct the cause, then recheck the system. lf all the input tests prove OK,
the cruise control unit may be faulty. Substitute a known-good cruise control unit and retest. lf the system works
properly, replace the cruise control unit.

Main Switch Test/Replacement
Remove the driver's dashboard lower cover (see
page 20-59).
Release the clips of the main switch and push the
main switch 1A) out of the panel, then disconnect
the 5P connector (B) from the main switch.

to prevent corrosion.
22. After installation, checkthatall tubes, hosesand
connectors are installed correctly.
23. Inspectforfuel leaks. Turn the ignition switch ON
{ll) {do not operate the starter) so that the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat thls operation two or three times, then
check for fuel leakage at any point in the fuel line.

air from the cooling system with the heater valve
open (see page 10-6).
25. Inspect the idle speed (see page 11-'138).
26. Inspect the ignition timing (see page 4-17).
Gylinder Head Cover lnstallation
1. Thoroughly clean the head cover gasket and the
groove.
2. Installthe head cover gasket (A) in the groove of
the cylinder head cover (B).
Check that the mating surfaces are clean and dry.
Apply liquid gasket. P/N 08718-0009, on the chain

Oil Pressure Switch Test
1. Remove the YEURED wire (A)from the engine oilpressure switch (B).
Check for continuity between the positive terminal(C) and the engine (ground). There should be
continuity with the engine stopped. There should
be no continuity with the engine running.
lf the switch fails to operate, check the engine oil
level. lf the engine oil level is OK. check the engine
oil pressure. lf the oil pressure is OK, replace lhe oil
Dressure switch.

Oil Pressure Test
lf the oil pressure indicator stays on with the engine
running. check the engine oil level. lf the oil level is
correct:
Connect a tachometer.
Remove the engine oil pressure switch, and install
an oil pressure gauge {A).

Sta rt the engine. Shut it off immediately if thegauge registers no oil pressure. Repair lhe problem
before continuing.
Allow the engine to reach operating temperature(fan comes on at least twice), The pressure should
be:
Engine Oil Temperature: 176'F (80'Cl
Engine Oil Pressure:
At ldle:70 kPa (0.7 kgf/cm', 10 psi)

lf the oil pressure is NOT within specifications,
inspect these items:. Check the oil screenforclogging.. Check the oil pump (see page 8-8).. Check crankshaft and connecting rod bearing
clearances.
