When Monitored:
Continuously
•
Set Condition:
When the Driver Door Lock Switch Mux circuit is under 2.6 volts for over 30 seconds.
Possible Causes
(G161) DRIVER DOOR LOCK SWITCH MUX WIRE PARTIAL SHORT TO GROUND
(P439) MEMORY SELECT SWITCH MUX WIRE PARTIAL SHORT TO GROUND
(P439) MEMORY SELECT SWITCH MUX CIRCUIT SHORTED TO THE (G920) MEMORY SELECT SWITCH
RETURN CIRCUIT
MEMORY SELECTOR SWITCH
DRIVER WINDOW/DOOR LOCK SWITCH STUCK
DRIVER MEMORY MIRROR MODULE
Theory of Operation
This code will only set in vehicles that have the Memory System. The supply circuit for the Memory Mirrors are
supplied by the Memory Mirror Module, therefore both the Memory Select Switch Mux or the Door Lock Switch Mux
circuits can cause this DTC.
