Frequently Asked Questions
Are both the GR hatchback and GV sedan body styles covered?
Yes. The manual addresses both the 5-door GR hatchback and the 4-door GV sedan body configurations sold from 2012 to 2014, including trim levels WRX, WRX-S, STI, STI-S, and SE variants where applicable.
Does this cover the STI’s 6-speed gearbox and DCCD system?
Full coverage is included for the STI-spec 6-speed close-ratio manual gearbox as well as the Driver-Controlled Center Differential (DCCD) found on STI models, including adjustment procedures and electronic control wiring.
Is the EJ257 high-output STI engine covered separately from the standard EJ255?
