DTC P0979 Dodge

Description

When the DSA switch is not activated, the signal to the DSA control module is high. The signal to the DSA control module is grounded when the switch is pressed in. This engages or disengages the DSA function. Diagnostic trouble code (DTC) DSA-121 is stored if the DSA control module registers that the signal from the switch is low for more than approximately 60 seconds when the engine is running. The DSA warning lamp lights. Note! The diagnostic trouble code (DTC) can then be stored if the DSA button is held pressed in for more than approximately 60 seconds. Fault causes of this type are not included in the fault-tracing procedure.
