Title: INTRODUCTION: REPAIR INSTRUCTION: INITIALIZATION; 2019 MY Corolla Corolla Hatchback Corolla HV GR Corolla [06/2018 - 01/2019]

INITIALIZATION

Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Perform steering sensor zero point calibration	Lane Control System
	Pre-collision System
	Lighting System (w/ AFS)(EXT)
Initialize back door lock	Power Door Lock Control System

PROCEDURES NECESSARY WHEN CABLE IS DISCONNECTED/RECONNECTED TO NEGATIVE (-) AUXILIARY BATTERY TERMINAL

NOTICE:

After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System)
