Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

When replacing the VSC actuator assembly, perform initialization of linear solenoid valve calibration (See CALIBRATION ).
for 1GR-FE:
If the ECM has been replaced, it is necessary to register the ECU (See REGISTRATION ).
for 2UZ-FE:
If the ECM has been replaced, it is necessary to register the ECU (See REGISTRATION ).
for 3UR-FE:
If the ECM has been replaced, it is necessary to register the ECU (See REGISTRATION ).
