  Q: What procedures and initializations are required when replacing or reconnecting components related to the Car Batteries, ECU, transmission, tire pressure system, steering, and key systems on Toyota Venza?

  A: Engine startup and steering lock release will be prevented after battery terminal changes unless the steering lock system runs its initialization sequence because of low battery voltage. To replace the ECU or other components dealers should use Techstream through which they must operate two functions: first they should read the VIN from the old ECU then they should apply the new VIN to the replacement ECM only when the stored VIN does not match the actual VIN of the vehicle. The Techstream requires resetting of the transaxle compensation code after replacing either the valve body assembly or shift solenoid valves SL3 and SL4 or TCM through a step-by-step procedure that starts with putting the shift lever to N or P then opening the ignition before proceeding to the Techstream menus. The TCM needs a road test to learn after memory reset since this procedure requires the Techstream for execution. The transaxle compensation code from the QR label must be recorded before reinstallation into the TCM since the correct 60-digit alphanumeric value is needed to prevent shift shock. The procedure for tire pressure warning systems entails using the Techstream to register transmitter IDs that become necessary during component replacement. Beforehand technicians should collect ID data using the Techstream as the tool for registration. The vehicle stability control system calibration needs an engine variant learning procedure through Techstream that follows specific steps to guarantee system functionality. When changing the power steering ECU or steering column assembly the system demands an initialization process for the rotation angle sensor while performing a calibration of the torque sensor zero point. When components need replacement in wireless door lock control systems without a smart key systems the registration process for recognition codes follows a set sequence of modes which includes adding, rewriting, confirming and prohibition of codes. Users need to register ID codes in the engine immobiliser system to activate both smart key functionality and related features and the Techstream performs the key addition and replacement procedures.
