AUTOMATIC TRANSAXLE [AW6A-EL, AW6AX-EL]
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 05-17-25 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 05-17-25 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 05-17-25 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 05-17-25 TCM
REMOVAL/INSTALLATION[AW6A-EL,
AW6AX-EL].)
Control Module Inspection
1. Remove the air cleaner component. (See 01-13-5 INTAKE AIR SYSTEM REMOVAL/INSTALLATION[L3 WITH
TC].)
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)".
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.
