Control Module: Testing and Inspection
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.
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.
3. Verify that the positions of the selector lever and the indicator light correspond.
^ If there is any malfunction, perform the neutral position learning.
4. Verify that the TR PID is normal.
^ If there is any malfunction, perform the neutral position learning.
Control Module Inspection
1. Remove the air cleaner component.
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.

3. Remove the TCM.
4. Verify that continuity or resistance at terminal is as indicated in the terminal continuity/resistance table.
^ If there is any malfunction, inspect the parts under "Inspection item (s)".
- If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the TCM.
