Switched System Power (SSP)

The SSP is invoked by both the FEM and REM. This function removes power from relays that provide power to the exterior lamps, interior lamps, and power door locks. This is only accomplished when both the FEM and the REM are in sleep mode. The sleep function of the FEM and REM places the modules in sleep mode when the ignition switch is in the OFF position, and no wake up (input) signals occur for 30 minutes. If a state change does occur, the 30 minute timer will reset and begin again. The module will not sleep if the parking lamps or the hazard lamps are active. The following relays are controlled by the SSP function: SSP1, SSP2, SSP3, and SSP4. When either the FEM or REM are not in sleep mode, all SSP relays will be energized. When energized, each relay will supply power to multiple features/functions. For additional information, refer to the SSP RELAY INDEX  for diagnosis and testing of SSP related issues. When diagnosing multiple symptoms and/or DTCs it is essential to determine if all are related to a single SSP or multiple SSP relay powered functions.
