On-Vehicle Inspection

Caution

• Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to allow water or foreign material on the connector when disconnecting.

• Do not damage the terminals.

1.Disconnect the negative battery cable.

2.Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)

3.Remove the TCM. (See TCM REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

4.Verify that there is no continuity between the coupler component terminals B12 and GND or B13 and GND.

• If there is any malfunction, inspect the coupler component.

• If the coupler component is normal, perform an off-vehicle inspection of input/turbine speed sensor. (See Off-Vehicle Inspection.)

Note

• Inspect with a tester that can indicate more than 10 megohms and confirm that the value is more than 1 megohm.

5.Verify that there is continuity between coupler component terminals B12 and B13.

• If there is any malfunction, inspect the coupler component.

• If the coupler component is normal, replace the input/turbine speed sensor. (See INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

6.Install the TCM. (See TCM REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

7.Install the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)

8.Connect the negative battery cable.

9.Perform the neutral position learning. (See NEUTRAL POSITION LEARNING [AW6A-EL, AW6AX-EL].)

Off-Vehicle Inspection

Caution

• Do not damage the terminals.

1.Connect the input/turbine speed sensor terminal 2 to the battery positive terminal, connect the battery negative terminal to input/turbine speed sensor terminal 1 through an ammeter set to a resistance of 100 ohm.

2.Measure the current while waving a magnet back and forth over the top of the input/turbine speed sensor (less than 5 mm {0.197 in}).

• If there is any malfunction, replace the input/turbine speed sensor. (See INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

3.Perform the mechanical system test. (See MECHANICAL SYSTEM TEST [AW6A-EL, AW6AX-EL].)
