Toyota Yaris: Repair Instruction / Inspection Mode Procedure

Toyota Yaris XP210 (2020-2024) Reapir and Service Manual / General / Introduction / Repair Instruction / Inspection Mode Procedure

INSPECTION MODE PROCEDURE

INSPECTION MODE

(a) for Gasoline Model, Diesel Model, LPG Model:

The following table shows the types of inspection mode that are available, their purpose and the control that occurs in mode.

Utility Items	Main Purpose	Control
Inspection Mode	For performing tests using a speedometer tester, two-wheel chassis dynamometer, four-wheel chassis dynamometer, etc.	Cancels TR(A)C and VSC systems

(b) for HV Model:

NOTICE:

When operating the vehicle in an inspection mode for an operation such as a speedometer test, a DTC may be stored. Therefore, if the warning light illuminates, check for DTCs using the GTS and clear the DTCs.

HINT:

If the engine is warmed up and the HV battery is charged, the engine will stop after the vehicle is stopped. If the engine is required to run continuously even after the vehicle is stopped, such as for an ignition timing check, switch to maintenance mode.

The following table shows the types of inspection mode that are available, their purpose and the control that occurs in each mode.

Mode (Display)	Purpose	Control
2WD MAINTENANCE MODE (2WD for measuring Exhaust Gas)	For inspecting ignition timing, performing engine maintenance, idle speed exhaust emissions testing (CO, HC), etc. For performing tests using a speedometer tester, two-wheel chassis dynamometer, etc.	Keeps the engine idling when the shift lever is in P or park (P) is selected Shuts down control of the rear motor (makes the vehicle operate in 2WD) Cancels traction control
2WD CERTIFICATION MODE (2WD for cutting TR(A)C)	For performing tests using a speedometer tester, two-wheel chassis dynamometer, etc.	Shuts down control of the rear motor (makes the vehicle operate in 2WD) Cancels traction control
4WD/AWD MAINTENANCE MODE (4WD for measuring Exhaust Gas)	For inspecting ignition timing, performing engine maintenance, idle speed exhaust emissions testing (CO, HC), etc. For performing tests using a speedometer tester, four-wheel chassis dynamometer, etc.	Keeps the engine idling when the shift lever is in P or park (P) is selected Cancels traction control
4WD/AWD CERTIFICATION MODE (4WD for cutting TR(A)C)	For performing tests using a speedometer tester, four-wheel chassis dynamometer, etc.	Cancels traction control

(1) Before activating inspection mode, turn the air conditioning off, start the hybrid system with the shift lever in P or with park (P) selected, and check that the engine stops within several seconds after starting (engine warm up check).

(2) Activate the appropriate inspection mode and inspect the vehicle:

Test Item	Mode
Vehicle straight traveling test (side slip inspection)	2WD MAINTENANCE MODE, 4WD/AWD MAINTENANCE MODE or normal mode
Braking force test	Normal mode
Speedometer test	2WD MAINTENANCE MODE or 4WD/AWD MAINTENANCE MODE
Exhaust gas test (idling)	2WD MAINTENANCE MODE or 4WD/AWD MAINTENANCE MODE
Headlight test	2WD MAINTENANCE MODE, 4WD/AWD MAINTENANCE MODE or normal mode

(3) Cancel inspection mode immediately after completing the inspection.

NOTICE:

Driving the vehicle without canceling inspection mode may damage the hybrid transaxle or the hybrid transmission.

(d) Precautions when performing speedometer test (for HV Model)

CAUTION:

Be sure to perform the test in 2WD MAINTENANCE MODE or 4WD/AWD MAINTENANCE MODE.

NOTICE:

Do not perform rapid starting or quick acceleration on a speedometer tester. If rapid starting or quick acceleration is performed on a speedometer tester, damage may occur to the hybrid transaxle or the hybrid transmission.

(1) Depress the accelerator pedal slowly and gradually accelerate the vehicle. Take a measurement.

(2) After the measurement, use the brakes to gradually decelerate the vehicle.

(e) Special notes for using a chassis dynamometer (for HV Model)

CAUTION:

Be sure to perform the test in 2WD MAINTENANCE MODE or 4WD/AWD MAINTENANCE MODE.

NOTICE:

Sudden acceleration or deceleration of the vehicle on a chassis dynamometer under minimal load may damage the hybrid transaxle or the hybrid transmission.

(1) Always set an appropriate load before starting the test.

(f) When testing with a drum tester such as a speedometer tester, combination tester for the speedometer and brakes, or chassis dynamometer, or when jacking up the front wheels and turning the wheels, perform the following procedure to enter Inspection Mode and disable the TR(A)C and VSC systems.

CAUTION:

Do not use the drum tester with any of the lock chains disconnected. Transaxel Type:

*A

for FRONT WHEEL DRIVE VEHICLES/2WD

*B

for 4WD/AWD

Transmission Type:

*A

for REAR WHEEL DRIVE VEHICLES/2WD

*B

for 4WD/AWD
Using the drum tester with a lock chain disconnected could cause the vehicle to begin moving unexpectedly.
Do not use the drum tester while the TR(A)C or VSC is able to operate. TransAxel Type:

*A

for FRONT WHEEL DRIVE VEHICLES/2WD

*B

for 4WD/AWD

TransMission Type:

*A

for REAR WHEEL DRIVE VEHICLES/2WD

*B

for 4WD/AWD
TR(A)C or VSC operation could cause the vehicle to begin moving unexpectedly.
