Subaru: Pre- and post-repair scan all vehicles since 2004 model year
Subaru this month released a position statement advising collision repairers to scan before and after a repair all vehicles dating back to the 2004 model year.
Hopefully, that definitive start date for the procedure placates insurers who this week have questioned whether OEMs who say that all vehicles should be scanned really mean it — despite what’s now been a year of OEMs and basically everyone else (I-CAR, ETI, ASA, SCRS) consistently stating that scanning has been important on all vehicles for years. (The idea that stating “all” is somehow unclear has rightfully been ridiculed by Nissan.)
For Subaru vehicles from model year 2004 and forward involved in a collision, Subaru collision repair procedure recommends that pre-repair scanning be performed. Pre-scanning will reveal DTCs for items that are not functioning properly in the vehicle. It allows a shop to identify any issues early in the estimate process, allowing a more complete estimate and encompassing repair process.
Additionally, Subaru collision repair procedure also recommends that post-repair scanning be performed on these vehicles. Post scanning is critical in ensuring the malfunctioning items have been repaired and there are no remaining DTCs. It may also assist in assuring the appropriate calibrations and reinitializations have been performed.
Subaru recommended that shops use the Subaru SSM4 and Denso DST-i interface device; details for these can be found here. Otherwise, it said a shop could use the middleman asTech device to connect to a remote Subaru scan tool. The OEM said it couldn’t vouch for any aftermarket scanners.
The OEM pointed out that cars are continuing to add or improve technology like “sensor, cameras, control units, as well as other components. … They are a critical part of vehicle operation and the safety
features in each Subaru vehicle.”
