Toyota 4Runner Firmware 4Runner_GRN28#_4.0_V689661-35F3189663-35801-MOD.bin
A catalog reference for the Toyota 4Runner GRN28# 4.0-liter firmware file and its MOD variant label.
4Runner_GRN28#_4.0_V689661-35F3189663-35801-MOD.bin is a modified firmware file cataloged for a Toyota 4Runner in the GRN28# model-code family with a 4.0-liter engine. The identifier does not establish which control module it belongs to or what vehicle function its software controls.
What the filename identifies
The GRN28# model-code pattern and 4.0 designation identify the vehicle family and engine displacement. The remaining string, V689661-35F3189663-35801, distinguishes this catalog entry but does not by itself establish a documented calibration function or a specific change from another revision.
The MOD suffix labels this file as a modified variant. It does not name the modification, so its effect on driving behavior or vehicle operation cannot be determined from the filename alone. The complete identifier is important when comparing this file with other records, since a similar prefix does not establish that two files have the same application.
