2. Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION

[MZI-3.7] .)

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

4. Verify that there is no continuity between coupler component terminals B1, B3, B4, B9, B10, B11, B14,

B17, B18, B21, B22 and GND.



If there is any malfunction, inspect the coupler component.



If the coupler component is normal, replace the control valve body. (See CONTROL VALVE
BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

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

6. Install the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-

3.7] .)

7. Connect the negative battery cable.

TCM INSPECTION [AW6A-EL, AW6AX-EL]

TR SWITCH OPERATING INSPECTION

1. Verify that the starter operates only when the ignition switch is turned to the START position with the

selector lever in P or N position.



If there is any malfunction, neutral position learning. (See TCM REMOVAL/INSTALLATION
[AW6A-EL, AW6AX-EL].)

2. Verify that the back-up lights illuminate when shifted to R position with the ignition switch at the ON

position.



If there is any malfunction, neutral position learning. (See TCM REMOVAL/INSTALLATION
[AW6A-EL, AW6AX-EL].)

3. Verify that the positions of the selector lever and the indicator light correspond.



If there is any malfunction, perform the neutral position learning. (See TCM
REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

4. Verify that the TR PID is normal.



If there is any malfunction, perform the neutral position learning. (See TCM
REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

CONTROL MODULE INSPECTION

1. Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION

[MZI-3.7] .)

2. Measure the voltage at each TCM connector (wiring harness-side) terminal and refer to the TERMINAL

VOLTAGE TABLE.



If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under
"Inspection item (s)".

VOLTAGE SPECIFICATION

WARNING:



Be careful not to damage the connector waterproofing when
measuring the TCM terminal voltage. If damaged, the
waterproofing efficiency could be negatively affected.

NOTE:



Use the ground of terminal A9 of the TCM connector (wiring harness-
side) when measuring terminal voltage, as an error may occur when
connecting the negative circuit tester to ground.
