Toyota Corolla Cross: On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY
(a) Before cleaning, or after cleaning the throttle body with motor assembly and installing it to the vehicle, turn the ignition switch to ON without operating the accelerator pedal sensor assembly.
NOTICE:
If the accelerator pedal sensor assembly has been operated, restart the procedure from the step above.
(b) Connect the GTS to the DLC3 and check for DTCs. If DTCs are stored, repair them by following the repair procedure flow. If DTCs are not stored, perform the throttle body operation check.
(c) Check throttle body operation.
(1) Enter the following menus:
Powertrain / Engine / Active Test / Control the ETCS Open/Close Slow Speed
(2) During Active Test operation, check the Data List items "Throttle Position Command" and "Throttle Position Sensor No. 1 Voltage".

(d) Warm up the engine.
NOTICE:
- The A/C switch and all accessory switches should be off.
- The electric fan should be off.
- After warming up the engine, check that the coolant temperature is 75° C or more.
(e) Check the "Throttle Position Sensor No.1 Voltage %".
(1) Read the Data List while quickly and fully depressing the accelerator pedal and check that the value for "Throttle Position Sensor No.1 Voltage %" is 60% or more.
(f) If there was any abnormality found during the throttle body operation check or "Throttle Position Sensor No.1 Voltage %" check, clean the throttle body, then reassemble it and perform the throttle body operation check again. If the operation returns to normal, the procedure is complete. If operation does not return to normal, replace the throttle body with motor assembly.
(g) Perform "Inspection After Repair" after replacing or cleaning the throttle body with motor assembly.

PROCEDURE
1. SECURE VEHICLE
(a) Fully apply the parking brake and chock a wheel.
CAUTION:
Make sure to apply the parking brake and chock a wheel before performing
this procedure.
If the vehicle is not secure and the shift lever is moved to N, the vehicle
may suddenly move
Power Source Mode does not Change to ON (IG)
DESCRIPTION If the power switch is pressed with the electrical key transmitter sub-assembly in the cabin, the certification ECU (smart key ECU assembly) receives a signal and changes the power source mode. Related Data List and Active Test Items
