1、SLIDING ROOF SLIDING ROOF SYSTEM RF3 RF SYSTEM DESCRIPTION 1.GENERAL This system has the following functions: manual slide open and close; auto slide open and close; manual tilt up and down; auto tilt up and down; jam protection; and key off operation. 2.FUNCTION OF MAIN COMPONENT 3.SYSTEM OPERATION
2、 The sliding roof has the following features. ComponentOutline Sliding roof drive gear sub-assembly (Sliding roof ECU)Sliding roof ECU controls sliding roof motor to rotate forward and backward, which tilts or slides sliding roof glass Overhead junction block Output of operation signals from built-i
3、n sliding roof switch to sliding roof ECU are handled by overhead junction block FunctionOutline Manual slide open and closeThis function causes sliding roof to open (or close) when SLIDE OPEN switch (or TILT UP switch) is pressed for a maximum of 0.3 seconds. Sliding roof stops as soon as switch is
4、 released. Auto slide open and closeThis function causes sliding roof to be fully opened (or closed) when SLIDE OPEN switch (or TILT UP switch) is pressed for a minimum of 0.3 seconds Manual tilt up and downThis function causes sliding roof to tilt up (or tilt down) when TILT UP switch (or SLIDE OPE
5、N switch) is pressed for a maximum of 0.3 seconds Auto tilt up and downThis function enables sliding roof to tilt up (or down) when TILT UP switch (or SLIDE OPEN switch) is pressed for a minimum of 0.3 seconds. Jam protection functionThe jam protection function automatically stops sliding roof, or s
6、tops sliding roof and makes it open halfway (or fully tilts it upward) if a foreign object gets jammed in sliding roof during auto close operation (or auto tilt down operation).

11、R SUB- ASSEMBLY NOTICE: When replacing the sliding roof drive gear, the sliding roof drive gear requires initialization. If a reset is not executed, the following functions do not operate: auto operation and key off operation. (a)Turn the ignition switch ON. (b)If the sliding roof is open, close it
12、fully. (c)By pushing the slide open switch of the slide switch or the up switch of the tilt switch on the personal light, make the sliding roof operate as follows: Tilt up approximately 1 second tilt down slide open slide closed. (d)Check that the sliding roof stops at the fully closed position. (e)
13、Finish the initialization. (f)Check that the AUTO operation works normally. NOTICE: If the following conditions occur while operating, initialization will fail. Ignition switch is turned OFF. Pushed sliding roof control switch is released while sliding roof is operating. Vehicle speed is 5 km/h (3 m
14、ph) or more. Communication is cut off. HINT: If the sliding roof cannot fully close or its position has become misaligned, perform the initialization again. If the sliding roof TILT UP switch or SLIDE CLOSE switch is pressed and held until the roof glass has either stopped moving or started moving i
15、n the opposite direction, and then the switch is held for another 10 seconds or more, perform the initialization again. If the AUTO operation function and jam protection function do not operate after the drive gear has been reset, replace the sliding roof drive gear (sliding roof ECU). SLIDING ROOF

24、iagnostic Trouble Codes (DTCs) can be read through the vehicles Data Link Connector 3 (DLC3). When the system seems to be malfunctioning, use the intelligent tester to check for malfunctions and perform repairs. 2.CHECK DLC3 The vehicle uses the ISO 15765-4 for communication protocol. The terminal a
25、rrangement of the DLC3 complies with ISO 15031-03 and matches the ISO 15765-4 format. HINT: Connect the cable of the intelligent tester to the DLC3, turn the ignition switch on and attempt to use the tester. If the display indicates that a communication error has occurred, there is a problem either
26、with the vehicle or with the tester. If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle. If communication is still not possible when the tester is connected to another vehicle, the problem may be in the tester itself. Consult the Serv
27、ice Department listed in the testers instruction manual. If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector.

43、oof glass moves but auto operation does not operate. 1.CHECK AUTO OPERATION (a)Turn the ignition switch ON. (b)When the roof glass is fully closed, press the SLIDE OPEN switch for 0.3 seconds or more. Check that the roof glass automatically slides until it is fully opened. (c)When the roof glass is
44、fully tilted up, press the SLIDE OPEN switch for 0.3 seconds or more. Check that the roof glass automatically slides until it is fully tilted down. (d)When the roof glass is fully open, press the TILT UP switch for 0.3 seconds or more. Check that the roof glass automatically slides until it is fully
45、 closed. (e)When the roof glass is fully closed, press the TILT UP switch for 0.3 seconds or more. Check that the roof glass automatically slides until it is fully tilted up. (f)When the auto operation is operating, check that pressing any sliding roof control switch stops the roof glass operation.
46、2.CHECK SLIDING ROOF OPERATION AFTER IGNITION SWITCH IS TURNED OFF (a)Turn the ignition switch from ON to OFF, and check that the sliding roof operates. Then open the driver side door once, and check that the sliding roof does not operate. (b)Turn the ignition switch from ON to OFF and wait for appr
47、oximately 45 seconds. Check that the sliding roof does not operate. (c)Operate the auto (SLIDE OPEN or TILT UP) operation. While the roof glass is in motion, turn the ignition switch from ON to OFF. Check that the auto operation continues until the roof glass opens or closes fully. 3.CHECK JAM PROTE
48、CTION FUNCTION CAUTION: Do not use a part of your body, for example, your hand, to check the jam protection. Do not allow anything to become caught in the sliding roof by accident in this procedure. Perform the inspection from the inside of the vehicle. NOTICE: Do not use hard objects, such as a ham
49、mer, to avoid damage to the roof. If the jam protection does not operate, reset the sliding roof drive gear (motor). RF14 SLIDING ROOF SLIDING ROOF SYSTEM RF (a)When the sliding roof auto operation is operating and an object is caught between the vehicle body and glass, check that the roof glass opens a distance of 218 mm (8.58 in.) from the point of contact with the object, or opens fully if an opening distance of 218 mm (8.58 in.) is not available.
