System Inspection

MANUAL CONTROL INSPECTION
1. Insert the key into the ignition switch and move the manual switch up/down and verify that the steering wheel tilts up/down. To solve faulty operation, follow the Diagnosis Chart.





Note
^ This control stops operation when the following occur.
1. Pull out the key from the ignition switch.
2. Manual switch is turned off.
3. Sensor senses bottom dead point.
4. Sensor senses manual operation upper limit position.
5. Electric current flows to the motor for more than 10 seconds.
6. Position sensor movement speed is below the set value (1°56'04"/sec.).

AUTO CONTROL (AWAY CONTROL) INSPECTION
1. With the auto switch turned on, verify that the steering wheel moves up until the sensor senses the top dead point when the ignition key is pulled out. To solve faulty operation, follow the Diagnosis Chart.





Note
^ This control stops operation when the following occur.
1. Auto switch is turned off.
2. Manual switch is turned on.
3. Sensor senses top dead point.
4. Electric current flows to the motor for more than 10 seconds.
5. Position sensor movement speed is below the set value (1°56'04"/sec.).
6. Ignition key is inserted again, and turned to ON or ACC.

AUTO CONTROL (RETURN CONTROL)
1. With the auto switch turned on, check that the steering wheel moves back to the position memorized by the computer (located inside the CPU) during manual control (i.e. the position before the ignition key was pulled out) after the ignition key is inserted and set it in the ACC position or ignition switch at ON. To solve faulty operation, follow the Diagnosis Chart.





Note
^ This control stops operation when the following occur.
^ Auto switch is turned off.
^ Manual switch is turned on.
^ Memorized position is reached.
^ Electric current flows to the motor for more than 10 seconds.
^ Position sensor movement speed is below the set value (1°56'04"/sec.).
^ In the initial state (when the battery is connected, or when the CPU is reset and there is no memorized position), the steering wheel returns to the neutral position.
^ The memorized position is updated every time adjustment is performed using manual control.
