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.

DTC SUMMARY MALFUNCTION DESCRIPTION When the ignition switch is turned from ON (READY) to off, the hybrid vehicle control ECU detects that the high-voltage capacitor inside the inverter with converter assembly is not discharged.
The cause of this malfunction may be one of the following: Inverter
A/F (O2) Sensor Positive Current Control Bank 1 Sensor 2 Circuit Short to Ground (P22AB11,P22AB12,P22AB13,P22AB16,P22AB17,P22B211,P22B212)
DESCRIPTION Refer to DTC P003612. Click here
HINT: Although the DTC titles say O2 sensor, these DTCs relate to the air fuel ratio sensor (sensor 2).
