DESCRIPTION
The power window regulator motor assembly is operated by the power window regulator master switch assembly or power window regulator switch assembly. The power window regulator motor assembly has motor, regulator and ECU functions.
This DTC is output when the ECU built into the regulator motor determines that the power window regulator master switch assembly or power window regulator switch assembly is stuck.
HINT:
DTC B2312 can be stored in the power window regulator master switch assembly and in each power window regulator motor assembly (power window ECU).
