PATS PIDs

In conjunction with DTCs, the PATS PIDs are a useful tool when diagnosing PATS concerns.

BCM MODULE PID CHART

Acronym	Name	Description
PCM_ID	PCM ID Status Stored	Indicates if there is a PCM identification currently stored in the BCM. Must read stored for the engine to start.
PCM_VERIFY	PCM Verify OK	Indicates if the module identification check between the BCM and the PCM passes. Must read yes for the engine to start.
START_ENABLD	Vehicle Enable Status	Indicates if PATS allows the engine to start. Must read enabled for the engine to start.

NOTE: The RFA module PATS PIDs do not actively display their current state. They only display the correct state when the ignition is turned to the ON mode

RFA MODULE PID CHART

Acronym	Name	Description
BCM_ID	BCM ID Status Stored	Indicates if there is a BCM identification currently stored in the RFA module. Must read stored for the engine to start.
BCM_VFY	BCM Verify OK	Indicates if the module identification check between the BCM and the RFA module passes. Must read yes for the engine to start.
MASTERKEY	Master Key Present	Indicates if the RFA module detects a programmed IA key in the vehicle. Must read stored for the engine to start.
MIN_KEYS	Minimum Number Of Keys Required	Minimum number of programmed keys required. This PID always reads 2.
N_KEYCODE	Number Of Programmed Keys	Number of keys currently programmed into the RFA module.
PATSENABL	PATS System Status - Enable Status	Indicates if PATS will allow the engine to start. Must read enabled for the engine to start.
