TCM INSPECTION [AY6A-EL, AY6AX-EL]

id0517k3330900

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. (See COUPLER COMPONENT INSPECTION [AY6A-EL, AY6AX-EL].)

1. Remove the fresh-air duct and air cleaner component as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

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 (s)” column in the “Terminal Voltage Table (Reference)”.
