    YES: Check CAN communication line. Refer to U1000 CAN COMM CIRCUIT .

    NO: GO TO 2.

  2. CHECK OVERDRIVE CONTROL SWITCH SIGNAL

    With CONSULT-III 

    1. Turn ignition switch ON.
    2. Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
    3. Read out ON/OFF switching action of the "SPORT MODE SW".

  3. CHECK OVERDRIVE CONTROL SWITCH

    Check overdrive control switch. Refer to "COMPONENT INSPECTION ".

    OK or NG 

    OK: GO TO 4.

    NG: Repair or replace damaged parts.

  4. CHECK SELF-DIAGNOSTIC RESULTS (COMBINATION METER)

    Perform self-diagnosis check. Refer to "SELF-DIAGNOSIS MODE OF COMBINATION METER ".

    Is any malfunction detected by self-diagnostic? 

    YES: Check the malfunctioning system.

    NO - 1: With Intelligent Key: GO TO 5.

    NO - 2: Without Intelligent Key: GO TO  7.
