15. FOR VEHICLES EQUIPPED WITH TRACTION CONTROL (TR(A)C) AND VEHICLE STABILITY CONTROL (VSC) SYSTEMS
(a) NOTICES FOR WHEN TESTING WITH DRUM TESTER
(1) When testing with a 2-wheel drum tester such as a speedometer tester, a combination speedometer and brake tester, or a chassis dynamometer, perform the following procedure to enter inspection mode and disable the TR(A)C and VSC systems Component Tests and General Diagnostics.
NOTICE:
* If the vehicle is tested in normal mode on the tester, TR(A)C and VSC operation may cause the vehicle to jump off of the tester.
* Secure the vehicle with chains for safety.
* Make sure to cancel inspection mode after completing a check using a 2-wheel drum tester.
* After performing a check, never drive the vehicle without canceling inspection mode.
HINT
* During inspection mode, the TRC and VSC systems are disabled and slip indicator light is illuminated.
* Inspection mode is canceled when the power switch is turned off. As a result, if it is necessary to perform an inspection after the power switch has been turned off, perform the procedure again to re-enter inspection mode.
(b) NOTICES FOR VSC RELATED PROCEDURES
(1) For VSC related parts, adjustments are required after removal and installation. Therefore, perform removal and installation only when necessary.
(2) When performing VSC related procedures, be sure to strictly follow the preparation and completion procedures.
(3) When performing removal and installation or replacement of VSC related parts, first disconnect the cable from the negative (-) auxiliary battery terminal.
16. ELECTRONIC SHIFT LEVER SYSTEM
(a) BASIC OPERATION
(1) This vehicle is equipped with an electronic shift lever system. This system electrically communicates the driver's intended shift state to the ECUs responsible for system control. The system also uses an electrically operated transaxle parking lock mechanism.
HINT
The parking lock mechanism of the transaxle cannot be operated if the auxiliary battery is discharged or has been disconnected. There is no mechanical connection between the P position switch (transmission shift main switch), shift lever and the transaxle.
(2) This system allows the driver to select the reverse (R), neutral (N), drive (D) and brake (B)* shift states using the shift lever or select park (P) by pushing the P position switch (transmission shift main switch). Shift states are ECU controlled based on the actions of the driver and various conditions. Shift states can be verified using the shift position indicator in the combination meter or by using the Techstream.
* *: For enhanced engine braking.
17. WHEN INSPECTING VEHICLES
NOTICE:
When the vehicle is run in inspection mode for an operation such as a speedometer test, a DTC may be set. Therefore, if the warning light comes on, after canceling inspection mode, check for DTCs using the Techstream and clear the DTCs.
(a) VEHICLE CONDITIONS
(1) Before activating inspection mode, turn the air conditioning off, start the hybrid system 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 Component Tests and General Diagnostics.
HINT
Different types of inspection mode are available. One is maintenance mode, and the other is certification mode. The following table indicates the mode appropriate for each test item.
The shift state for each test is as follows:
(3) Cancel inspection mode immediately after completion of inspection.
NOTICE:
Driving the vehicle without canceling inspection mode may damage the transaxle.
(b) WHEN USING A BRAKE TESTER
CAUTION:
Be sure to perform the test in maintenance mode.
NOTICE:
* A high-speed type brake tester cannot be used.
* Vehicle speed should be less than 0.5 km/h (0.3 mph).
* Follow all usage and safety procedures in the operator's manual for the brake tester.
(1) Place the wheels to be tested (front or rear) onto the rollers.
(2) Start the hybrid system to allow normal brake booster operation.
(3) Move the shift lever to N and confirm that neutral (N) has been selected.
(4) Operate the brakes to perform the test.
(c) WHEN USING A SPEEDOMETER TESTER
CAUTION:
Be sure to perform the test in 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 transaxle.
(1) Depress the accelerator pedal slowly and gradually accelerate the vehicle. Make a measurement.
(2) After the measurement, use the brakes to gradually decelerate the vehicle.
(d) WHEN USING A CHASSIS DYNAMOMETER
(1) Always set an appropriate load before starting the test.
NOTICE:
Sudden acceleration or deceleration of the vehicle on a chassis dynamometer under minimal load may damage the transaxle.
(e) WHEN USING AN ON-VEHICLE BALANCER
(1) Raise the vehicle until all 4 wheels are off the ground.
(2) Support the vehicle with safety stands at an appropriate height. Make sure that the vehicle does not lean in any direction, and that the tires are completely clear of the floor.
(3) Place the vibration pick-up unit into position for the wheel to be measured*1.
(4) Release the parking brake.
(5) Check that no dragging force exists when turning each wheel by hand.
(6) Put the wheel balancer in position.
(7) Wheel balance measurement should be done by using both the engine and the wheel balancer drive roller to spin the wheels.
HINT
*1: Different on-vehicle wheel balancers have different requirements for mounting the vibration pick-up unit(s). Refer to the operator's manual for the wheel balancer to confirm requirements for use.
NOTICE:
* Be sure to perform the test in maintenance mode.
* Start the engine and then increase the vehicle speed gradually with drive (D) selected.
* Do not accelerate or decelerate suddenly.
* Deceleration should be done by braking gradually.
* Make sure that no one is standing in-line with the spinning wheels.
* Measurement should be done quickly.
* Confirm that the vehicle is securely immobilized.
* Follow all usage and safety procedures in the operator's manual for the wheel balancer.
18. WHEN TOWING VEHICLES
(a) Use one of the following methods to tow the vehicle.
(b) If the vehicle has trouble with the chassis or drivetrain, use method 1 (flatbed truck).
NOTICE:
Do not use any towing method other than those shown above.
(c) If a tow truck is not available, in an emergency vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet(s). This should only be attempted on hard surfaced roads for short distances below 30 km/h (19 mph).
A driver must be in the vehicle to steer and operate the brakes. The vehicle's wheels, drivetrain, axles, steering and brakes must be in good condition.
(1) Emergency towing procedure
1 Turn the power switch on (IG).
2 Depress the brake pedal and move the shift lever to N.
3 Release the parking brake.
4 Release the brake pedal slowly.
