Jeep Grand Cherokee WK2 Electric Power Steering Pump Part No. P05154662AB (2014-2015)

es. Installing SKU: JP466K requires electronic calibration and a dedicated scan tool routine. The pump's integrated Power Steering Control Module (PSCM) communicates directly across the high-speed CAN-C bus network. Once the replacement unit is bolted in and connected, a diagnostic scanner (such as Chrysler/Jeep wiTECH, Autel MaxiSYS, or Launch X431) must be used to perform the "Steering Angle Sensor (SAS) Centering" routine and clear stored communication codes. Furthermore, an automated scan-tool-guided EHPS air-bleed cycle must be run to purge air trapped within the steering rack without dry-running or overheating the internal brushless motor.

A failing electro-hydraulic unit on the Grand Cherokee WK2 platform typically displays "Service Power Steering" on the dashboard instrument cluster alongside heavy, non-assisted manual steering. Diagnostic trouble codes most frequently logged include: * U0131: Lost Communication with Power Steering Control Module (indicates board-level electrical failure or CAN bus drop-out). * C1532: Electric Power Steering Internal Circuit Malfunction. * C1526: Steering Assist System Temperature High (frequently triggered when fluid deteriorates and internal motor resistance spikes during heavy Australian off-road or towing use). * C2210: ECU Internal Performance / Logic Failure.

Yes. For the 2014–2015 Jeep Grand Cherokee (WK/WK2 series), the leading letter "P" is simply the Mopar parts distribution prefix, and "05154662" represents the physical pump casting, internal reservoir, and hydraulic motor design. The two-letter revision suffix (AA, AB, AC, AD) tracks factory production software and internal supplier revisions. P05154662AB directly interchanges with 05154662AA, 05154662AC, and 05154662AD across 3.6L Pentastar V6, 3.0L CRD Diesel, and 5.7L V8 models equipped with factory electric-hydraulic steering. Always verify that your failing pump is the electro-hydraulic type with high-pressure fluid fittings and electronic harness plugs, rather than the traditional belt-driven mechanical pump found on select early export models.
