REPAIR INSTRUCTION INITIALIZATION

PROCEDURES NECESSARY WHEN CABLE IS DISCONNECTED/RECONNECTED TO BATTERY TERMINAL

Procedures Necessary when Cable is Disconnected/Reconnected to Battery Terminal
Necessary Procedure	Effect or Inoperative Function when Necessary Procedure is not Performed	See page
Reset back door unlock position	Back door unlock function	Click here

Note

After the battery is reconnected, be sure to wait 10 seconds or more before attempting to start the engine. The engine may not start immediately after the battery is reconnected
Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.
for 1WW:

As a result, after turning the ignition switch off, make sure to wait at least 1 minute before disconnecting the cable from the negative (-) battery terminal.
w/ Radio and Display Receiver Assembly:

After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 60 seconds before disconnecting the cable from the negative (-) battery terminal.
