Diagnostic Procedure

  1. CHECK PNP SW SIGNALS 

    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 "P", "R", "N", "D" and "L" position switches moving selector lever to each position.

    OK or NG 

    OK: Adjust control cable. Refer to "ADJUSTMENT OF CVT POSITION ".

    NG: Check PNP switch (Refer to test group 1) again after adjusting PNP switch (Refer to PARK/NEUTRAL POSITION (PNP) SWITCH ).

  4. DETECT MALFUNCTIONING ITEM 

    Check the following items.

    • Harness for short or open between ignition switch and PNP switch.
    • Harness for short or open between PNP switch and TCM.
    • 10A fuse [No.14, located in the fuse block (J/B)].
    • Ignition switch. Refer to "POWER SUPPLY ROUTING CIRCUIT ".

    OK or NG 

    OK: GO TO 5.

    NG: Repair or replace damaged parts.

  5. CHECK DTC 

    Perform "DTC CONFIRMATION PROCEDURE ".

    OK or NG 

    OK: INSPECTION END 

    NG: GO TO 6.

  6. CHECK TCM 
    1. Check TCM input/output signals. Refer to "TCM INPUT/OUTPUT SIGNAL REFERENCE VALUES ".
    2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.

    OK or NG 

    OK: INSPECTION END 

    NG:

    1. Repair or replace damaged parts.
    2. Replace the transaxle assembly. Refer to "REMOVAL AND INSTALLATION (MR20DE) ".
