The main body ECU (multiplex network body ECU) communicates with the power window regulator motor assembly (for rear RH door) via LIN communication.
This DTC is stored when a power window regulator motor assembly (for rear RH door) is malfunctioning, or the ECU built into the power window regulator motor assembly (for rear RH door) determines that the fully closed power window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| B231F96 | RR-Door P/W Motor Component Internal Failure | Either condition is met: (a)
Power window regulator motor assembly (for rear RH door) is malfunctioning (b)
ECU in power window regulator motor assembly (for rear RH door) determines that fully closed power window position has deviated approx. 20 mm (0.787 in.) or more from normal position |
·
Incorrect installation of power window components ·
Overheated power window regulator motor assembly (for rear RH door) ·
Power window regulator motor assembly (for rear RH door) ·

Inspect the fuses for circuits related to this system before performing the following procedure.
If a power window regulator motor assembly (for rear RH door) has been replaced with a new one, initialize the power window control system.
If a power window regulator motor assembly (for rear RH door) and door window regulator sub-assembly have been removed and installed, or if a power window regulator motor assembly (for rear RH door) was reused when a door glass or door glass run was replaced, initialize the power window control system.
The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
Operate the rear power window regulator switch assembly (for RH door) and check that the rear RH door power window operates normally.
