System Function Test

Actuator on turbocharged models cannot be checked using ACC Tester (49 9200 010). SeeFig 1 . Turbocharged models can be tested with an ohmmeter only. When checking actuator on models with automatic transmission, the checker must be modified by cutting lead wire at terminal No. 6 on ACC checker connector. SeeFig 2 . The main switch, actuator-VAC, actuator-VENT 2, actuator-VENT 1, clutch/brake switch, combination/inhibitor switch (automatic transaxle models), and generator are verified by check lights on tester.

Tester has a check switch and a slide switch. Check switch tests actuator operation with engine running. When switch is held on with engine running, engine speed is increased and held at 2000-3000 RPM. If RPMs do not increase, adjust free play of actuator inner cable. Free play for all models is .004-.012" (1.0-3.0 mm).Slide switch should be moved to "H" position before check switch is used.

NOTE: When installing ACC tester, turn ignition and main switch off. When performing all testing steps, main and ignition switches must be in "ON" position. Generator light can be on or off during testing.

When testing main switch continuity, all lights except clutch/brake switch and combination/inhibitor switch should be on. If all lights are off, check fuse, connectors, ignition, and main switches.
To test inhibitor switch continuity, shift automatic transmission vehicles to "D" position. All lights except clutch/brake switch and combination/inhibitor switch should be on. If combination/inhibitor switch light is on, check wiring and switch.
To test brake switch continuity, shift automatic transmission vehicles to "D" position and depress brake pedal. All lights except combination/inhibitor switch should be on. If clutch/brake switch light is off, check switch and wiring.
To test clutch switch continuity on manual transaxle models, depress clutch pedal. See step 3) for correct lighting response. If clutch brake switch light is off, check switch and wiring.
To test "SET", "COAST", or "RESUME" position of combination switch, shift automatic transaxle vehicles into "D" position and turn switch to appropriate position. All lights except clutch/brake switch light should be on. If combination/inhibitor switch light is off, check appropriate switch position and wiring.
Start engine and shift A/T vehicles into "N" position. All lights except clutch/brake switch should be on. On manual transmission vehicles, combination switch should be off. Test actuator operation by setting slide switch to "H". Turn check switch "ON" and hold.
Engine speed should increase to 2000-3000 RPM. All lights should be off except main switch and combination/inhibitor switch on A/T vehicles only (light will be out on M/T vehicles). VAC light should flash.
To check speed sensor output, drive vehicle slowly. All lights except clutch/brake and combination/inhibitor switch should be on. If generator light does not flash, speed sensor or wiring is faulty.
Check actuator solenoid resistance. Resistance should measure 23-40 ohms while checking terminals "A-C", "B-C" and "C-D". SeeFig 3 .
