    Tech Tips


    • This inspection is not for the No. 1 integration relay itself, but for the wire harness that is connected to the No. 1 integration relay. If the result is within the specified condition, the No. 1 integration relay may be malfunctioning.

    • If the result is not as specified, a short between No. 1 integration relay and one of the electrical loads is suspected.

    • Make sure that the malfunction is reproduced when performing the inspection below.

    • After the wire harness has been repaired, disconnect all connectors that are connected to the No. 1 integration relay, and turn the power switch on (READY) to clear the DTCs.
