Toyota Corolla Cross: Road Test
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 change gear ratios or changes
ratios at the wrong engine speed, conduct the following road test while referring
to the speed variation chart and attempt to duplicate the problem symptoms.
ROAD TEST
CAUTION:
- 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.
NOTICE:
- This test must be performed after checking and confirming that the engine
is normal.
- Perform this test with the CVT fluid temperature between 50 and 100°C (122
and 212°F).
- Perform this test with the air conditioning off.
HINT:
- Lock-up control will not operate when the CVT fluid temperature is 20°C
(68°F) or less and the vehicle speed is 60 km/h (37 mph) or less, or when the
CVT fluid temperature is 5°C (41°F) or less.
- Lock-up control will not operate when the engine coolant temperature is
20°C (68°F) or less.
- The lock-up OFF vehicle speed may vary depending on electrical load, and
air conditioning and brake operation.
- Keep a constant accelerator pedal opening angle to maintain the specified
vehicle speed.
- When fully depressing the accelerator pedal, read the engine speed immediately
after the pedal is fully depressed.

(a) D position test
Move the shift lever to D and check the following:
(1) Check if the gear ratio changes during normal driving (average urban driving).
- With the vehicle stopped, fully depress the accelerator pedal and check
the engine speed at the shift timing listed in *1 and *2 in the speed variation
chart.
- With the vehicle stopped, depress the accelerator pedal to a constant intermediate
position and check the engine speed when the vehicle reaches the vehicle speed
listed in *3 in the speed variation chart.
- Release the accelerator pedal and check the engine speed when the vehicle
decelerates to the vehicle speed listed in *4 in the speed variation chart.
- Release the accelerator pedal and check the engine speed when the vehicle
decelerates to the vehicle speed listed in *5 in the speed variation chart.
- Fully depress the accelerator pedal and check the engine speed as the vehicle
accelerates from the vehicle speed listed in *6 in the speed variation chart.
(2) Check for abnormal noises and vibration.
HINT:
Inspections for the cause of abnormal noise and vibration must be done thoroughly
as they could also be due to loss of balance in the differential, torque converter
clutch, etc.
(3) Check for abnormal shock and slippage at kick-down.
(4) Check the lock-up mechanism.
(b) M position test
Move the shift lever to M and check the following:
(1) Check the shift operation.
- When driving with M10 selected (vehicle speed approximately 95 to 100 km/h
(59 to 62 mph)), check the engine braking effect in M9 when the shift lever
is moved to "-".
- When driving with M9 selected (vehicle speed approximately 90 to 95 km/h
(56 to 59 mph)), check the engine braking effect in M8 when the shift lever
is moved to "-".
- When driving with M8 selected (vehicle speed approximately 80 to 90 km/h
(50 to 56 mph)), check the engine braking effect in M7 when the shift lever
is moved to "-".
- When driving with M7 selected (vehicle speed approximately 70 to 80 km/h
(43 to 50 mph)), check the engine braking effect in M6 when the shift lever
is moved to "-".
- When driving with M6 selected (vehicle speed approximately 60 to 70 km/h
(37 to 43 mph)), check the engine braking effect in M5 when the shift lever
is moved to "-".
- When driving with M5 selected (vehicle speed approximately 50 to 60 km/h
(31 to 37 mph)), check the engine braking effect in M4 when the shift lever
is moved to "-".
- When driving with M4 selected (vehicle speed approximately 40 to 50 km/h
(25 to 31 mph)), check the engine braking effect in M3 when the shift lever
is moved to "-".
- When driving with M3 selected (vehicle speed approximately 30 to 40 km/h
(19 to 25 mph)), check the engine braking effect in M2 when the shift lever
is moved to "-".
- When driving with M2 selected (vehicle speed approximately 20 to 30 km/h
(12 to 19 mph)), check the engine braking effect in M1 when the shift lever
is moved to "-".
(c) R position test
Move the shift lever to R and lightly depress the accelerator pedal. Check that
the vehicle moves backward without any abnormal noise or vibration.
CAUTION:
Before conducting this test, make sure that the test area is free from people
and obstructions.
(d) P position test
Stop the vehicle on an incline (approximately 5° or more). Move the shift lever
to P and release the parking brake. Check that the parking lock pawl holds the vehicle
in place.
