Circuit Description
The memory function switches are normally open and are wired to the driver door switch assembly (DDSA). When the memory recall 1 switch is pressed, the switch pulls the 5 volt circuit from the driver door switch assembly (DDSA) low. The DDSA senses that the memory recall 1 switch circuit is low and a class 2 message is sent out identifying that the circuit is active.
Conditions for Running the DTC
The DDSA must be powered and can not have B1328 - Battery Voltage High or B1327 - Battery Voltage Low as active DTCs for this DTC to set.
Conditions for Setting the DTC
If the memory recall 1 switch circuit is active for more than 30 continuous seconds, the circuit will be considered shorted, and the DDSA will set this DTC.
Action Taken When the DTC Sets
The DDSA ignores the invalid switch input from the memory function switch and will not respond to it. The DDSA will respond to all other valid switch inputs.
Conditions for Clearing the DTC
The DTC automatically clears when the switch circuit setting the DTC is no longer active.
