)ON-VEHICLE INSPECTION
1. Function inspection of throttle body ASSY (with motor)
CAUTION:
Be sure to perform the function inspection after assembly of the throttle body or removal / installation of the component parts.
(1) Remove the EFI-MAIN fuse (7.5 A) and ETCS fuse (15 A), wait for 60 seconds or more, and then reconnect the fuses.
(2) After installing the throttle body to the vehicle, turn the ignition switch to ON without operating the accelerator pedal.
CAUTION:
If the accelerator pedal is operated by mistake, repeat the steps from the beginning.
(3) Connect the SSM3 to the DLC.
(4) Clear the diagnostic code using the SSM3.
(5) Start the engine, and check that the check engine warning light does not illuminate and that the idle speed is within standard value with A/C OFF after warming up the engine.
Standard value
: 600 to 800 r/min
CAUTION:
Perform this check with all accessory switches turned OFF, A/C OFF, electric fan OFF, N or P position selected.
(6) When the accelerator pedal is depressed rapidly down to the full-open position or around, check that [Data monitor] → [Throttle Opening Angle] value varies smoothly in synchronism with the pedal depression.
(7) Perform the driving test, and check that the feeling of strangeness is not provided.
