PRECAUTIONS FOR INSPECTING POWER SOURCE FOR MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) (for LHD)
As the door control battery is installed between the vehicle battery and main body ECU (multiplex network body ECU), a door control battery malfunction can be suspected if the power source for the main body ECU (multiplex network body ECU) is malfunctioning.
POWER WINDOW CONTROL SYSTEM PRECAUTIONS
Note
The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
The power window control system prohibits the auto up and down function when the jam protection function malfunctions.
If the power window regulator motor assembly has been replaced with a new one, initialize the power window control system.
If the power window regulator motor assembly and door window regulator sub-assembly have been removed and installed, or if the power window regulator motor assembly was reused when a door glass or door glass run was replaced, initialize the power window control system.
The jam protection function may operate unexpectedly, even when the power window control system is normal, due to detection of a value different than the operation learned value when the door glass moving speed changes sharply under any of the following conditions:
A power window is being opened or closed while the vehicle is driven on a rough road.
A power window is being opened or closed while the door is being opened or closed.
The voltage changes abruptly.
Do not disconnect the battery while the ignition switch is ON. Otherwise, DTC B2313 will be stored.
