Road Test [10/2022 - ]

WARNING: This page is about a different car, the 2025 Lexus RX 350, 2024 Lexus RX 350, and 2023 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
  1. PROBLEM SYMPTOM CONFIRMATION 
    1. Based on the result of the customer problem analysis, try to reproduce the symptoms. If the problem is that the transaxle does not shift up, shift down, or the shift point is too high or too low, conduct the following road test referring to the automatic shift schedule and simulate the problem symptoms.
  2. ROAD TEST 
    WARNING:
    • Strictly observe posted speed, limits, traffic laws and road conditions.

    • Do not drive the vehicle with the cable of the GTS contacting the pedals, shift lever or steering wheel.
    • Driving the vehicle with the cable of the GTS contacting these areas could impede vehicle control, resulting in a serious accident.
    • Do not operate the GTS while driving the vehicle.

    • Operating the GTS while driving the vehicle will prevent you from paying sufficient attention to vehicle surroundings, and could result in a serious accident.
    NOTE:
    • Be sure to inspect and adjust the engine before performing these tests.
    • Perform the road test with the engine coolant temperature between 60 and 100°C (140 and 212°F) and the ATF temperature between 50 and 100°C (122 and 212°F).
    • Perform these tests with the air conditioning and cruise control off.
      Inspection Procedure
      Transmission Floor Shift Assembly Test With the vehicle stationary and move the shift lever as follows to select each shift state: D → M → D. Check that the meter display changes from D to the appropriate M gear and then back again.
      Shift Paddle Switch Test While driving with the shift state manual (M), operate the shift paddle to "+" and "-". Check that the meter display changes accordingly.
      D Position Shift Test While driving the vehicle normally, check that the transaxle shifts up and down through each gear properly.
      Lock-up Function While driving on a level surface at a constant speed in the lock-up range with the shift state drive (D), lightly depress the accelerator pedal and check that the engine speed does not change abruptly.
      P Position Test Stop the vehicle on an incline (approximately 5° or more). Then push the P position switch (shift position indicator) to select park (P) and release the parking brake. Check that the parking lock pawl holds the vehicle in place.
      Abnormal Noise and Vibration Check for abnormal noise and vibration while driving the vehicle forward and backward, and during shift operations.
      Fluid Leakage After performing all other road test inspections, check for fluid leakage.

    HINT: 

    When checking for DTCs after a repair, drive the vehicle according to the monitor drive pattern.

    Refer to MONITOR DRIVE PATTERN [10/2022 - ] 

    1. Gear change confirmation
      1. Enter the following menus: Powertrain / Transmission / Data List.

        Powertrain > Transmission > Data List 

        Tester Display
        Vehicle Speed
        Coolant Temperature
        NT Sensor Speed
        A/T Oil Temperature No. 1
        Shift Status
      2. Check that the transaxle shifts to each gear while gently accelerating to 85 km/h (53 mph) or higher.

        HINT: 

        • Check that the value of NT Sensor Speed drops by 50 rpm or more when the value of Shift Status increases.
        • Depending on the engine speed when the gear is changed, it may be difficult to see the change of NT Sensor Speed.
    2. Lock-up confirmation
      1. Enter the following menus: Powertrain / Transmission / Data List.

        Powertrain > Transmission > Data List 

        Tester Display
        Vehicle Speed
        Engine Speed
        Coolant Temperature
        Accel Position from EFI
        NT Sensor Speed
        A/T Oil Temperature No. 1
        Lock Up Status
        Shift Status
      2. When the following conditions are met, check that the difference between Engine Speed and NT Sensor Speed is 50 rpm or less.

        Lock-up Schedule

        Vehicle Speed
        (Constant speed)        		 85 km/h (53 mph)
        Shift Status 8th
        Lock Up Status ON

        HINT: 

        • If Lock Up Status does not change to ON, decrease the accelerator pedal opening angle or increase the vehicle speed.
        • Lock-up will not be engaged if the accelerator pedal is released.
        • Lock-up prohibition conditions:
          • Engine coolant temperature is less than 20°C (68°F)
          • ATF temperature is less than 20°C (68°F) or higher than 110°C (230°F)
          • Throttle valve is fully closed
          • Stop light switch is on
