         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.

         Test No. 5 (Vehicle Speed Sensor Circuit)

         When vehicle moves slowly, 0-2 or more volts should alternate

at terminal No. 19 of cruise control unit. If circuit does not test

correctly, replace sensor as necessary or repair harness.

         Test No. 6 (Vacuum Pump Circuit)

         1) When cruise system is in deceleration or release mode,

battery voltage should be present on terminals No. 26 and 13 of cruise

control unit. If circuit does not test correctly, replace vacuum pump

as necessary or repair harness.

         2) When cruise system is in release mode, battery voltage

should be present on terminal No. 12 of cruise control unit. When

cruise system is in hold mode, voltage on terminals No. 12, 13 and 26

will go from battery voltage to zero volts depending on driving

conditions. If circuit does not test correctly, replace vacuum pump as

necessary or repair harness.

         Test No. 7 (Stoplight Switch Circuit)

         When brake pedal is pressed, battery voltage should be

present on terminal No. 15 of cruise control unit. If voltage is not

present, adjust or replace brake switch. 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 (Inhibitor Switch Circuit)

         When transmission is in Neutral position, battery voltage

should be present on terminal No. 1 of cruise control unit. If circuit

does not test correctly, replace switch as necessary or repair

harness.

         Test No. 10 (Overdrive Switch Circuit)

         When overdrive switch is pushed to ON position, battery

voltage should be present on terminal No. 11 of cruise control unit.

If circuit does not test correctly, replace switch as necessary or

repair harness.

         Test No. 11 (Idle Switch & Throttle Position Sensor Circuit)

         1) When accelerator pedal is pressed, 4.5-5.5 volts should be

present on terminal No. 4 (idle switch) of cruise control unit. When

accelerator pedal is released, voltage should not be present on

terminal No. 4 of cruise control unit.

         2) When accelerator pedal is pressed to wide open throttle,

4.0-5.5 volts should be present on terminal No. 5 (throttle position

sensor) of cruise control unit. When accelerator pedal is released, .

5-.7 volts should be present on terminal No. 5 of cruise control unit.

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

repair harness.
