Component Tests and General Diagnostics
INTRODUCTION: REPAIR INSTRUCTION: INSPECTION MODE PROCEDURE
1. INSPECTION MODE
NOTICE:
If the vehicle is run in the inspection mode, for such as a speedometer test, a DTC may be set. Therefore, if the warning light comes on, after canceling the inspection mode, check for DTCs using the Techstream and clear the DTCs.
HINT
* If the engine is warmed up and the battery is charged, the engine of the vehicle will stop after the vehicle stops. Therefore, if the engine is required to run continuously even after the vehicle stops, such as for an ignition timing check, switch to the AWD inspection mode.
* The vehicle is equipped with the AWD system by which the rear wheels are electronically controlled by the motor, VSC system, and TR(A)C system. Therefore, it is necessary to switch to the FWD inspection mode and cancel all of these systems when only the front wheels are required to be rotated on a chassis dynamometer.
(a) Inspection mode purpose and control performed
(b) Vehicle conditions
(1) Before activating inspection mode, turn the air conditioning off, start the engine with the shift lever in P, and check the engine stops within several seconds after starting (engine warm up check).
(2) Activate inspection mode and inspect the vehicle. The shift position for each test is as follows:
(3) Reset inspection mode immediately after completion of inspection.
NOTICE:
Driving the vehicle without resetting inspection mode may damage the transaxle.
(c) Special notes for speedometer test
CAUTION:
Be sure to perform the test in the FWD inspection mode.
NOTICE:
Do not use the chassis dynamometer to perform rapid starting or quick acceleration/deceleration without first setting the proper load on the vehicle. Failing to set the load may damage 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) Special notes for 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.

(m) Deactivating inspection mode
(1) Turn the power switch off. The HV system turns off simultaneously.
HINT
The idle speed in inspection mode is approximately 900 rpm. The engine speed increases to 1500 rpm if the accelerator pedal is depressed midway with the shift lever in P. If the accelerator pedal is depressed more than midway, or if the accelerator pedal is fully depressed, the engine speed increases to approximately 2500 rpm.
NOTICE:
* If a DTC is set during inspection mode, the master warning light and the warning message illuminate on the multi-information display.
* When the master warning light and the warning message illuminate during inspection mode, deactivate inspection mode, and check the DTC(s).
* Driving the vehicle without deactivating inspection mode may damage the transaxle.
