Component Tests and General Diagnostics

TCM INSPECTION [AY6A-EL]

CAUTION:
- Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
- Do not damage the terminals.

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.
- For the inspection on the coupler component side of the TCM, refer to the coupler component inspection. Testing and Inspection

1. Remove the fresh-air duct and air cleaner component as a single unit. Service and Repair

2. Connect the voltmeter (-) lead to body GND.

3. Measure the voltage at each terminal.

- If any incorrect voltage is detected, inspect the related system(s), wiring harnesses and connector(s) referring to the "Inspection Item" column in the "TCM Terminal Voltage".
