INSPECTION PROCEDURE: P0A2C (TCDA)

1.

Set the starter key to the "LOCK" position and wait for approxi-
mately 3 hours. (To make the motor temperature equivalent to the
ambient temperature)

2.

Disconnect the PCU harness (12P) connector.

3.

Using the electrical tester, measure the resistance between the
terminals of PCU harness (12P) vehicle-side connector.
