DESCRIPTION
The power window regulator motor assemblies are operated by the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assemblies. The power window regulator motor assemblies have motor, regulator and ECU functions.
This DTC is stored when the ECU built into a power window regulator motor assembly and multiplex network master switch assembly determine that the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly is stuck.
