Identification & application notes

The offered item is labelled AYC MR405906. Amayama's exact genuine-parts record independently identifies MR405906 as an AYC control unit.
Skyline Spares' own used-stock/application description names MR405906 for Evo V/VI CP9A. This supports a probable specialist application reference, not a VIN-selected manufacturer fitment guarantee.
The linked exact catalogue diagrams could not be retrieved. Amayama's broad Colt/Lancer model hints must not be treated as ordinary Colt compatibility, and model/engine context does not establish exact interchange.
Mitsubishi recall 660, filed 22 August 2000, covers AYC computers in specified Evo IV/V CN9A/CP9A vehicles. The recall status and approved supersession of this offered module remain UNCONFIRMED. This record does not declare the offered stock recalled or certify it as the countermeasure part.
Match the complete supplier label, VIN/build, AYC system specification, approved replacement number and diagnostic/setup requirements. Do not describe this AYC module as ACD or ABS.
Tested and working is Nick’s Garage’s owner statement. No independent test method, date or certification has been supplied; it does not establish compatibility or approved replacement status.

Confirm before ordering

These details remain unconfirmed for this individual item:

Exact selected Evo V/VI variant, market and production cut-offs
Complete offered supplier revision and approved supersession
Recall/countermeasure status of this physical module and required diagnostic/setup procedures

Safety-system verification SRS, ABS and EPS components must be matched to the vehicle and full module revision by a qualified automotive technician. Installation may require coding, calibration and diagnostic checks. An owner-confirmed working condition does not establish compatibility or certify the vehicle’s safety system.
