INSPECTION MODE PROCEDURE

INSPECTION MODE

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 Techstream 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, enter CDY-2E (maintenance mode).

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

Purpose

Control

CDY-2E (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
  • Cancels traction control

CDY-2 (certification mode)

(2WD for cutting TRC)

For performing tests using a speedometer tester, two-wheel chassis dynamometer, etc.

Cancels traction control

(b) Vehicle conditions

(1) Before activating inspection mode, turn the air conditioning off, start the hybrid system with the shift lever in P, 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)

CDY-2E (maintenance mode) or normal mode

Braking force test

Normal mode

Speedometer test

CDY-2E (maintenance mode)

Exhaust gas test (idling)

CDY-2E (maintenance mode)

Headlight test

CDY-2E (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.

(c) Precautions when performing speedometer test

CAUTION:

Be sure to perform the test in CDY-2E (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.

(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.

(d) Special notes for using a chassis dynamometer

CAUTION:

Be sure to perform the inspection in CDY-2E (maintenance mode).

NOTICE:

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

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

(e) Activating CDY-2E (maintenance mode) (Not using the Techstream)

(1) Perform steps (A) through (D) within 60 seconds.

  1. Turn the power switch on (IG). (Step A)
  2. Move the shift lever to P and fully depress the accelerator pedal twice. (Step B)
  3. Move the shift lever to N and fully depress the accelerator pedal twice. (Step C)
  4. Move the shift lever to P and fully depress the accelerator pedal twice. (Step D)

(2) Start the engine by turning the power switch on (READY) while depressing the brake pedal.

HINT:

The idle speed in CDY-2E (maintenance mode) is approximately 1100 rpm with the shift lever in P. The engine speed increases to 1500 rpm when the accelerator pedal is depressed midway with the shift lever in P. When the accelerator pedal is depressed more than midway, or when the accelerator pedal is fully depressed, the engine speed increases to approximately 2500 rpm.

(3) Check that "CDY-2E" is displayed on the multi-information display.

(f) Activating CDY-2E (maintenance mode) (Using the Techstream)

(1) Connect the Techstream to the DLC3.

(2) Turn the power switch on (IG).

(3) Turn the Techstream on.

(4) Enter following menus: Powertrain / Hybrid Control / Utility / Inspection Mode - 2WD for measuring Exhaust Gas.

Powertrain > Hybrid Control > Utility

(5) Start the engine by turning the power switch on (READY) while depressing the brake pedal.

HINT:

The idle speed in CDY-2E (maintenance mode) is approximately 1100 rpm with the shift lever in P. The engine speed increases to 1500 rpm when the accelerator pedal is depressed midway with the shift lever in P. When the accelerator pedal is depressed more than midway, or when the accelerator pedal is fully depressed, the engine speed increases to approximately 2500 rpm.

(6) Check that "CDY-2E" is displayed on the multi-information display.

(g) Activating CDY-2 (certification mode) (Not using the Techstream)

(1) Perform steps (A) through (D) within 60 seconds.

  1. Turn the power switch on (IG). (Step A)
  2. Move the shift lever to P and fully depress the accelerator pedal 3 times. (Step B)
  3. Move the shift lever to N and fully depress the accelerator pedal 3 times. (Step C)
  4. Move the shift lever to P and fully depress the accelerator pedal 3 times. (Step D)

(2) Start the engine by turning the power switch on (READY) while depressing the brake pedal.

(3) Check that "CDY-2" is displayed on the multi-information display.

(h) Activating CDY-2 (certification mode) (Using the Techstream)

(1) Connect the Techstream to the DLC3.

(2) Turn the power switch on (IG).

(3) Turn the Techstream on.

(4) Enter following menus: Powertrain / Hybrid Control / Utility / Inspection Mode - 2WD for cutting TRC.

(5) Start the engine by turning the power switch on (READY) while depressing the brake pedal.

(6) Check that "CDY-2" is displayed on the multi-information display.

(i) Deactivating inspection mode

(1) Turn the power switch off and wait at least 30 seconds. The hybrid system will turn off simultaneously.

NOTICE:

  • If a DTC is stored while in inspection mode, the master warning light will illuminate and a warning message will be displayed on the multi-information display.
  • If the master warning light illuminates and a warning message is displayed on the multi-information display while in inspection mode, check for DTCs.
