Circuit Description
The switch or circuit that failed and generated this diagnostic trouble code (DTC) is one of the power window switches or circuits that are built into the driver door switch assembly (DDSA). Power and ground is internally supplied by the DDSA. Except for the power door serial data circuit, there are no external circuits concerned with power window operation from the DDSA. The DDSA contains a microprocessor which interprets the signals generated by the switches and assigns them a digital message. The DDSA then sends this message over the power door serial data circuit to the driver door module (DDM). The switches are not serviced separately.
