Subaru offers a new ECM for 2015-2019 WRX vehicles designed to address DTC P2610 (ECM/PCM engine off-timer performance). Under certain “rare” conditions, an electrostatic surge may influence the ECM’s internal timer used after the engine is turned off and store a DTC P2610 in memory. Hardware in the new ECM has been changed to eliminate any impact from electrostatic surges. The new ECM was incorporated into production starting with VIN K9820661 for MT models and K8820856 for CVT-equipped models.
