2. Check the drive pulley pressure control solenoid valve.
a) Remove the air filter and air duct.
b) Disconnect the solenoid valve connector.
c) Measure the resistance of the drive pulley pressure control solenoid valve.
- Nominal resistance - 3.8 - 6.8 Ohm
d) If necessary, connect the positive battery terminal to terminal "1" and the negative battery terminal to terminal "2". Make sure that the valve clicks.
3. Check the start inhibit solenoid valve.
a) Disconnect the solenoid valve connector.
b) Measure the resistance between the terminals of the solenoid valve connector.
- Nominal resistance - 11.7 - 21.0 Ohm
c) If necessary, connect the positive battery terminal to terminal "1" and the negative battery terminal to terminal "2". Make sure that the valve clicks into place.

5. Check the starting clutch control solenoid valve.
a) Remove the air filter and air duct.
b) Disconnect the solenoid valve connector.
c) Measure the resistance between the terminals of the solenoid valve connector.
- Nominal resistance - 3.8 - 6.8 Ohm
d) If necessary, connect the positive battery terminal to terminal "1" and the negative battery terminal to terminal "2". Make sure that the valve clicks into place.
6. Check the manual gear ratio change mode switch.
a) Remove the steering wheel.
Note: Refer to the instructions in the chapter "Supportive Restraint System (SRS)".
b) Make sure that there is conductivity between terminals "8" and "9" of the gear switch connector when the switch is pressed and that there is no conductivity when the switch is released.
7. Check the gear ratio change switches on the steering wheel.
a) Remove the steering wheel.
b) Check for conductivity between terminals "6" and "9" of the gear ratio change switch connector with the "+" switch (gear ratio increase switch) pressed.
c) If necessary, remove the upshift switch on the steering wheel and make sure that there is continuity between the terminals of its connector when the switch is pressed.
d) Check for conductivity between terminals "7" and "9" of the gear ratio change switch connector when the switch is pressed (gear ratio reduction switch).
c) If necessary, remove the downshift switch on the steering wheel and make sure that there is continuity between the terminals of its connector when the switch is pressed.
8. Check the start inhibit switch.
a) Remove the air filter.
b) Disconnect the start inhibit switch connector.
c) Measure the conductivity between the connector terminals according to the table.
