Inspection Procedure

WARNING: This page is about a different car, the 2006 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

NOTE: In DATA LIST DETAIL  , the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
  1. Warm up the engine.
  2. Turn the ignition switch OFF.
  3. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
  4. Turn the ignition switch ON.
  5. Turn the intelligent tester ON.
  6. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
  7. Follow the instructions on the tester and read the DATA LIST.
    DATA LIST DETAIL

    Item Measurement Item/Range (Display) Normal Condition Diagnostic Note
    PNP SW (NSW) PNP switch status/ON or OFF Shift lever is:
    On P or N: ON
    Not on P or N: OFF    		 When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
    LOW PNP switch status/ON or OFF Shift lever is:
    On L: ON
    Not on L: OFF    		 When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
    2ND PNP switch status/ON or OFF Shift lever is:
    On 2: ON
    Not on 2: OFF    		 When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
    3RD PNP switch status/ON or OFF Shift lever is:
    On 3: ON
    Not on 3: OFF    		 When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
    4th/DRIVE PNP switch status/ON or OFF Shift lever is:
    On 4: ON
    Not on 4: OFF    		 When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
    REVERSE PNP switch status/ON or OFF Shift lever is:
    On R: ON
    Not on R: OFF    		 When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
    DRIVE PNP switch status/ON or OFF Shift lever is:
    On D: ON
    Not on D: OFF    		 When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
  1. INSPECT PARK/NEUTRAL POSITION SWITCH 
    1. Disconnect the P1 PNP switch connector.
    2. Measure the resistance of the PNP switch when the shift lever is moved to each position.

      Standard resistance

    NG: REPLACE PARK/NEUTRAL POSITION SWITCH 

    OK: GO TO NEXT STEP 

  2. INSPECT TRANSMISSION CONTROL SWITCH 
    1. Disconnect the A48 switch connector.
    2. Measure the resistance of the switch when the shift lever is moved to each position.

      Standard resistance
