Glass & Power Window System: Other Subaru BRZ ZC

Precautions

1. Precautions for Power window system CAUTION: Power window system uses large-scale multiplex communication for vehicle body [LIN]. At first, follow the "How to proceed the troubleshooting" and perform the "Communication function checking" to check that malfunction does not occur in the communication system, and then proceed to the troubleshooting. When malfunction occurs in the auto-reverse function of the power window system, disable the AUTO operation. Otherwise, accidental pinching may arise. Check that the diagnostic code is not output, then proceed to the troubleshooting. When replacing the power window regulator motor assembly with a new one or reusing its motor, perform the initialization of the power window system. (Refer to «REGISTRATION SETTINGS»(ref-619153-S22744377692014053000000) ) After replacing door glass and/or weather strip, AUTO UP operation sometimes activates auto-reverse function. In this case, the door glass is fully closed by performing the procedure in the following order (*3). AUTO U0 HOLD -->(the auto-reverse function (glass reverse operation)) -->(*1) -->AUTO U0 HOLD -->(the auto-reverse function (glass reverse operation)) -->AUTO UP HOLD (*2). *1: If DOWN operation, IG OFF & timer operation OFF, and/or index operation is executed between auto-reverse function and AUTO UP HOLD, return to the beginning of the procedure. *2: The upper end position of the glass is relearned by this operation (AUTO UP HOLD). (Refer to «FUNCTION INSPECTION»(ref-619153-S13009156852014053000000) ) *3: The failure of the door glass or regulator may prevent full closing of the door glass. Even if the power window system is normal, unexpected operation of the auto-reverse function may occur resulting from the abrupt change of the opening/closing speed of the window. This symptom occurs when the system detects any value out of the learned operation. Window opening/closing operation while driving the vehicle on rough roads. Window opened/closed operation when door is opened/closed. Sudden voltage variation occurs. Never disconnect the battery with IG ON. If the battery is disconnected while IG ON, DTC may not be output properly.

Verify when the driver's seat switch on the power window regulator master switch assembly is operated to DOWN in two stages, the driver's seat door glass operates AUTO DOWN, and driver's seat door glass is fully open. Verify while AUTO DOWN is in operation, when the driver's seat switch on the power window regulator master switch assembly is operated to UP, the door glass moves up. Verify while AUTO UP is in operation, when the driver's seat switch on the power window regulator master switch assembly is operated to DOWN, the door glass moves down. Inspection of basic function (passenger's seat) Turn the ignition switch to ON. Verify when the switch on the power window regulator switch assembly is operated to UP in two stages, the passenger's seat door glass operates AUTO UP, and passenger's seat door glass is fully closed. Verify when the switch on the power window regulator switch assembly is operated to DOWN in two stages, the passenger's seat door glass operates AUTO DOWN, and passenger's seat door glass is fully open. Verify while AUTO DOWN is in operation, when the switch on the power window regulator switch assembly is operated to UP, the door glass of the passenger's seat moves up. Verify while AUTO UP is in operation, when the switch on the power window regulator switch assembly is operated to DOWN, the door glass of the passenger's seat moves down.
4. Function inspection of remote controlled manual operation Turn the ignition switch to ON. Verify when the remote control switch for the power window regulator master switch assembly for passenger's seat is operated to UP, the power window (passenger's seat door glass) moves up. Verify when the remote control switch for each seat on the power window regulator master switch assembly is operated to DOWN, the power window (passenger's seat door glass) moves down.
5. Function inspection of remote controlled automatic operation Turn the ignition switch to ON. Verify when the remote control switch for passenger's seat on the power window regulator master switch assembly is operated to UP in two stages, the passenger's seat door glass operates AUTO UP, and passenger's seat door glass is fully closed. Verify when the remote control switch for passenger's seat on the power window regulator master switch assembly is operated to DOWN in two stages, the passenger's seat door glass operates AUTO DOWN, and passenger's seat door glass is fully open.
6. Function inspection of after-key-OFF operation After turning IG from ON to OFF, verify that all seat's power windows are operable by the power window regulator master switch assembly. Also verify that after driver's or passenger's door is opened, the power window cannot be opened. After turning IG from ON to OFF, verify that passenger's seat power window is operable by the power window regulator switch assembly. Also verify that after driver's or passenger's door is opened, the power window cannot be opened. When approx. 45 seconds have passed after IG was turned from ON to OFF, verify that all power windows cannot be operated by the power window regulator master switch assembly. However, if the auto-reverse function is in operation, the operation continues until it is completed. (AUTO operation stops when 45 seconds pass.)
7. Inspection of auto-reverse function Basic function inspection CAUTION: Never use your hand or other part of your body to be pinched for checking the function. Work with great care for accidental pinching. NOTE: Auto-reverse function is operable with IG ON when AUTO UP or manual UP is in operation. Fully open all power windows (door glasses). Hold a styrene foam block (approx. 12 cm (4.72in) thick) or equivalent on the position where it is caught when the door glass is fully closed. When full close operation of the power window (door glass) is activated with AUTO UP or manual UP operation, verify that the window stops at the position where it contacts with styrene foam block or equivalent, comes into DOWN operation, and stops where it moves down approx. 200 mm (8 in). NOTE: If pinching is detected, it moves down approx. 50 mm (2 in) after stopping, and stops. If opening of the window is less than approx. 200 mm (8 in), however, it moves down approx. 200 mm (8 in) or 10 seconds and stops. During DOWN operation, make sure that the UP operation cannot be activated by the power window regulator master switch assembly.
8. Inspection of index function Make sure that when the driver's or passenger's door is opened, the window glass of the opened side moves down approx. 20 mm (0.8 in) automatically from fully closed position. Make sure that when the driver's or passenger's door is closed, the window glass of the closed side moves up to fully closed position. NOTE: If the window glass opens over approx. 20 mm (0.8 in) from the fully closed position, no index control is performed. Even if the window glass is open more than approx. 20 mm (0.8 in) because of looseness of the regulator, however, the window moves up automatically.
9. Inspection of power window regulator master switch assembly (driver's seat) Inspection of operation indicator Make sure that when performing IG OFF -->ON with connector connected, the operation indicator (LED), located on switch part of the power window regulator master switch assembly, lights up.
10. Inspection of power window regulator switch assembly (passenger's seat) Inspection of operation indicator Make sure that when performing IG OFF -->ON with connector connected, the operation indicator (LED), located on switch part of the power window regulator switch assembly, lights up.

Registration Settings

1. Initialization of power window regulator motor

Note. After battery replacement, no initialization for power window regulator motor is needed because the nonvolatile memory stores the necessary information.
