Toyota Yaris: When Replacing Or Removing/installing Parts / Ecu Configuration

HINT:

• Exterior lighting systems
• Interior lighting systems (Make them unlit even when a door is open)
• Air conditioning system
• Audio/Navigation systems
• Seat belt warning system (Lock belt buckles by inserting tongue plates)
• Accessory parts of aftermarket installation
• Other, generic electrical parts (such as remote engine starter, security system)

CAUTION:

• If the reprogramming is conducted with a weak vehicle battery, an auxiliary charge does not prevent a voltage drop, which may disable the ECU in reprogramming and damage it.
• Be sure to use the battery tester by connecting to a terminal on the vehicle directly.

CAUTION:

• When manually setting the current settings of the battery charger, be careful not to overcharge the battery.
• A fuse may blow if the battery charger is on when the battery charger is connected to the vehicle. Make sure that the battery charger is off when the battery charger is connected to the vehicle.

CAUTION:

• Make sure that the ignition switch remains ON when performing ECU configuration, and that the engine is not started.
• To prevent incidents related to unauthorized persons operating the GTS or vehicle, do not leave the vehicle unattended.
• It is necessary to log in to the Toyota server to perform an ECU configration update.
• Users other than Toyota dealers can log in with a guest account issued when an ECU is ordered.
