CIRCUIT TESTS (1992)
NOTE: To identify circuit connector terminals, See Figs. 22-29.
For wiring diagram, See appropriate chassis wiring diagram in
the WIRING DIAGRAMS Section.
Test No. 1 (Power & Ground Circuit)
1) Turn ignition on. When cruise control main switch is
turned to ON position, battery voltage should be present on terminal
No. 2 of cruise control unit connector.
2) If voltage is not present, check fuse No. 11 and replace
as necessary. If fuse is okay, check and repair harness as necessary.
Terminal No. 8 should be grounded at all times. If terminal No. 8 is
not grounded, repair harness.
Test No. 2 (Set Switch Circuits)
When set switch is turned to ON position, 3 volts should be
present on terminal No. 18 of cruise control unit. When set switch is
turned to OFF position, voltage should not be present on terminal No.
18 of cruise control unit. If circuit does not test correctly, replace
switch as necessary or repair harness.
Test No. 3 (Resume Switch Circuit)
When resume switch is turned to ON position, 6 volts should
be present on terminal No. 18 of cruise control unit. When resume
switch is turned to OFF position, voltage should not be present on
terminal No. 18 of cruise control unit. If circuit does not test
correctly, replace switch as necessary or repair harness.
Test No. 4 (Cancel Switch Circuit)
When cancel switch is turned to On position, battery voltage
should be present on terminal No. 18 of cruise control unit. When
cancel switch is in Off position, voltage should not be present on
terminal No. 18 of cruise control unit. If circuit does not test
correctly, replace switch as necessary or repair harness.

Colt, Colt 200, Mirage & Summit
Remove defogger timer from junction block under left side of
instrument panel. Connect a battery and test light to defogger timer
terminals. See Fig. 3. Apply battery voltage to terminal No. 7 for 5-7
seconds. Ensure test light illuminates for approximately 10 seconds.
Reapply battery voltage to terminal No. 7. Test light should go off
when voltage is applied again.
Colt Vista
With ignition switch in ON position, apply battery voltage to
terminal No. 2 of defogger timer. Timer should operate for
approximately 11 seconds then stop. See Fig. 3.
Eclipse & Galant
Remove defogger timer from interior relay block. Connect
battery voltage and test light to timer. See Fig. 3. Ensure test light
illuminates for approximately 11 seconds when battery voltage is
applied to terminal No. 4. Reapply battery voltage to terminal No. 4
and observe test light. Test light should go off.

GRID TEST
1) Start engine and operate at 2000 RPM. Ensure battery is
fully charged. Turn defogger switch to ON position. Using a voltmeter,
check voltage at center section of each grid wire. If voltage is
approximately 6 volts, grid wire is okay. If voltage is approximately
12 volts, an open is present in the negative circuit. Move probe
slowly toward the negative terminal to determine location of open
circuit.
2) If voltage is zero volt, an open is present in the
positive circuit. Move probe slowly toward the positive terminal to

INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
