Code P0513 Description

The Remote Keyless Entry (RKE) system uses non-switched battery current received through a fused B(+) fuse in the Totally Integrated Power Module (TIPM) so that the system remains operational regardless of the ignition switch position. The Sentry Key Remote Entry Module (SKREEM) (also known as the Wireless Control Module (WCM) or the Sentry Key Immobilizer Module (SKIM)) is the primary RKE system controller as well as the Radio Frequency (RF) RKE receiver. The SKREEM validates the vehicle access code of each RKE transmitter from which it receives RF signal inputs. It ignores requests from any transmitter for which it has no stored vehicle access code.
The SKREEM communicates and shares resources with the TIPM and many other electronic modules in the vehicle over the CAN data bus. The SKREEM also stores the RKE system Customer Programmable feature settings received over the CAN data bus from the EVIC circuitry of the CCN. When the SKREEM receives an input from a valid transmitter source, it uses these settings and internal programming to send the appropriate electronic request messages to the TIPM and other electronic modules over the CAN data bus to invoke the proper RKE system features and responses.
The Diagnostic Trouble Code (DTC) will set when the Powertrain Control Module (PCM) detects an invalid Sentry Key Remote Entry Module (SKREEM) key.
