         CIRCUIT TESTS (1991)

NOTE:    To identify circuit connector terminals, See  Figs. 17-21.

         For wiring diagram, See appropriate chassis wiring

         diagram in the WIRING DIAGRAMS Setion.

         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. 7 of cruise control unit connector.

         2) If voltage is not present, check fuse No. 3 and replace as

necessary. If fuse is okay, check and repair harness as necessary.

Terminal No. 10 should be grounded at all times. If terminal No. 10 is

not grounded, repair harness.

         Test No. 2 (Set Switch Circuits)

         When set switch is turned to ON position, voltage should not

be present on terminal No. 5 of cruise control unit. When set switch

is turned to OFF position, battery voltage should be present on

terminal No. 5 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, voltage should

not be present on terminal No. 4 of cruise control unit. When resume

switch is turned to OFF position, battery voltage should be present on

terminal No. 4 of cruise control unit. If circuit does not test

correctly, replace switch as necessary or repair harness.

         Test No. 4 (Vehicle Speed Sensor Circuit)

         When vehicle moves slowly, voltage should alternate from zero

volts to 3-5 volts at terminal No. 15 of cruise control unit. If

circuit does not test correctly, replace sensor as necessary or repair

harness.

         Test No. 5 (Actuator Circuit)

         1) When cruise control main switch is in On position, voltage

should not be present on terminal No. 8 of cruise control unit.

         2) When vehicle is accelerated using resume switch, voltage

should not be present on terminal No. 9 of cruise control unit. When

vehicle is coasting by using set switch, battery voltage should be

present on terminal No. 9.

         3) When vehicle is accelerated using resume switch, battery

voltage should be present on terminal No. 20 of cruise control unit.

When vehicle is coasting by using set switch, voltage should not be

present on terminal No. 20 of cruise control unit. If circuit does not

test correctly, replace actuator as necessary or repair harness.

         Test No. 6 (Stoplight Switch Circuit)

         1) When brake pedal is pressed, battery voltage should be

present on terminal No. 3 of cruise control unit. If voltage is not

present, adjust or replace brake switch.

         2) Battery voltage should be present at all times on terminal

No. 11 of cruise control unit. If voltage is not present, check fuse

no. 7. If fuse is okay, repair harness.

         Test No. 7 (Inhibitor Switch Circuit)

         1) When gear shift lever is moved to Neutral or Park

position, voltage should not be present on terminal No. 2 of cruise

control unit.

         2) When gear shift lever is moved to any other position,

battery voltage should be present on terminal No. 2 of cruise control

unit. If circuit does not test correctly, replace switch as necessary

or repair harness.

         Test No. 8 (Clutch Switch Circuit)

         When clutch pedal is pressed, battery voltage should be

present at terminal No. 1 of cruise control unit. If circuit does not

test correctly, replace switch as necessary or repair harness.

         Test No. 9 (Overdrive Switch Circuit)

         When overdrive switch is pushed to ON position, battery

voltage should be present on terminals No. 13 and 14 of cruise control

unit. If circuit does not test correctly, replace switch as necessary

or repair harness.
