ACTIVE TEST

NOTE: Beware that if the connector to the hand-held tester becomes disconnected or a communication error occurs during the ACTIVE TEST, the vehicle could become inoperative (READY lamp OFF).

HINT: Performing an ACTIVE TEST using the hand-held tester enables components including the relay, VSV, and actuator, to be operated without removing any parts. Performing an ACTIVE TEST as the first step of troubleshooting is one method to shorten diagnostic time. It is possible to display items in the DATA LIST during the ACTIVE TEST.

b. Turn the power switch ON (IG).
c. Turn the hand-held tester ON.
d. Select the following menu items: DIAGNOSIS / OBD/MOBD / HV ECU / ACTIVE TEST.
