INSPECTION PROCEDURE
Note
When the multiplex network master switch assembly connector or multiplex network switch assembly (applicable location) connector is disconnected, the power window control system must be initialized Click here.
Since the power window control system has functions that use multiplex communication, first confirm that there is no malfunction in the multiplex communication system by inspecting the multiplex communication functions in accordance with the How to Proceed with Troubleshooting procedures Click here. Then, conduct the following inspection procedure.
PROCEDURE
CHECK POWER WINDOW CONTROL SYSTEM (WINDOW LOCK SWITCH)
Check that the multiplex network switch assemblies (front passenger, rear LH and rear RH side) are disabled when the window lock switch of the multiplex network master switch assembly is pressed.
| OK |
|---|
| Multiplex network switch assemblies (front passenger, rear LH and rear RH side) are disabled. |
Check that the multiplex network switch assemblies (front passenger, rear LH and rear RH side) operate when the window lock switch is pressed again.
| OK |
|---|
| Multiplex network switch assemblies (front passenger, rear LH and rear RH side) can be operated. |
