Powertrain control module for the 2018 Jeep Grand Cherokee WK2 with the 5.7L engine. The WK2-generation Grand Cherokee (2011-2020) uses an advanced NGC-derived controller located in the front of the engine compartment, driver side, managing a high-complexity powertrain including electronic throttle, variable valve timing, and the ZF 8HP 8-speed automatic transmission.

The 5.7L WK2 calibration incorporates Eco mode fuel-saving logic, ESS (Engine Stop-Start) where equipped, and Quadra-Trac/Quadra-Drive transfer case integration. Typical PCM failure symptoms on this platform: transmission delayed engagement on cold start, multiple stored DTCs clearing then returning within one drive cycle, complete instrument cluster blackout due to internal CAN driver failure, and intermittent loss of cruise control or ESS function.

Ships VIN-programmed with RF Hub or SKREEM immobilizer pairing and Selec-Terrain mode calibration intact. Verified on vehicle network simulator for proper CAN-C, CAN-IHS, and LIN bus communication.
