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 01-13-5 INTAKE AIR SYSTEM REMOVAL/INSTALLATION[L3 WITH
TC].)
3. Remove the TCM. (See 05-17-25 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. (See05-17-16 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 05-17-17
INPUT/TURBINE SPEED SENSOR
REMOVAL/INSTALLATION[AW6A-EL,
AW6AX-EL].)
6. Install the TCM. (See 05-17-25 TCM REMOVAL/
INSTALLATION[AW6A-EL, AW6AX-EL].)
7. Install the air cleaner component. (See 01-13-5
