CHECK UNIT REPRODUCIBILITY

Perform the following procedure for each unit, and then perform reproducibility test.

1.

Turn ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Disconnect the unit connector.

4.

Connect the battery cable to the negative terminal.

5.

Make sure that the symptom filled in the “Symptom” of the check sheet is reproduced. (Do not confuse it
with the symptom related to removed unit.)

6.
