Tech Tips
When the ignition switch is turned off after the door control battery is fully charged, the door control battery becomes completely discharged due to self-discharge within approximately 30 minutes.
Approximately 90 seconds after the ignition switch is turned on (IG), the door control battery becomes fully charged.
When approximately 30 minutes or more elapse after the ignition switch is turned off, the Active Test may not be able to be performed.
Turn the ignition switch off.
Connect the GTS to the DLC3.
Turn the GTS on.
Enter the following menus: Body Electrical / Main Body / Active Test.
Note
Do not perform the Active Test at this time.
Disconnect the cable from the negative (-) battery terminal.
Repeat the "Shock Detection Unlock" Active Test until the multiplex network body ECU (main body ECU) communication lost error "Lost communication with vehicle" appears on the GTS display.
Note
When the door control battery becomes completely discharged and the power supply is cut, the multiplex network body ECU (main body ECU) communication lost error "Lost communication with vehicle" appears on the GTS display.
The number of times the Active Test can be performed depends on the charge condition of the door control battery.
