Title: UB80E (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: ROAD TEST; 2018 - 2024 MY Camry [03/2017 -        ]

ROAD TEST

PROBLEM SYMPTOM CONFIRMATION

(a) 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.

ROAD TEST

CAUTION:

  • Strictly obey all traffic rules and regulations.
  • Do not drive the vehicle with the Techstream cable contacting the pedals, shift lever or steering wheel.
  • Driving the wheel with the Techstream cable contacting these areas could impede vehicle control, resulting in a serious accident.
  • Do not operate the Techstream while driving the vehicle.
  • Operating the Techstream while driving the vehicle will prevent you from paying sufficient attention to vehicle surroundings, and could result in a serious accident.

NOTICE:

  • 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 Control Switch Test

    With the vehicle stationary and the shift lever in D, move the shift lever to S and return it to D. Check that the meter display changes from D to the appropriate S gear and then back again.

    S Position Test

    While driving with the shift lever in S, move the shift lever 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 lever in 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 move the shift lever to 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.

(a) Gear change confirmation

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Enter the following menus: Powertrain / Transmission / Data List.

Powertrain > Transmission > Data List

Vehicle Speed

Coolant Temperature

NT Sensor Speed

A/T Oil Temperature No.1

Shift Status

(4) 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.

(b) Shift schedule confirmation

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Enter the following menus: Powertrain / Transmission / Data List.

NOTICE:

  • All vehicle speeds indicated in the above table are actual values. Therefore, if checking a shift point with a chassis dynamometer, keep in mind that there is a margin of error in the chassis dynamometer indication.
  • If checking a shift point against the vehicle speed indicated on the speedometer, remember to consider the speedometer correction rate and margin of error in the tester indication.
