Inspection Procedure

NOTE: Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data record the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

Hand-held tester: 

  1. Connect hand-held tester, and check STA signal. 

    PREPARATION;

    1. Connect the hand-held tester to the DLC3.
    2. Turn the ignition switch to ON and turn the hand-held tester ON.
    3. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL / STARTER SIG.

    CHECK:

    Read the STA signal on the hand-held tester while the starter operates.

    OK:

    TESTER CONNECTION AND SPECIFIED CONDITION

    Ignition Switch Position ON START
    STA Signal OFF ON
    1. OK Check for intermittent problems (See  PRE-CHECK  ). 
    2. NG GO TO NEXT STEP 
  2. Check park/neutral position switch (A/T) or clutch start switch (M/T). 

    A/T models: 

    Inspect the park/neutral position switch. 

    PREPARATION:

    Disconnect the P1 park/neutral position switch connector.

    CHECK:

    Measure the resistance between each terminal shown below when the shift lever is moved to each range.

    OK:
