SLIDING ROOF: SLIDING ROOF SYSTEM: ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION
NOTE: The drive gear (motor) must be reset (pulse sensor's location must be set) when: one of the following occurs: 1) the battery cable has been disconnected from the negative (-) battery terminal, 2) the drive gear connector is connected / disconnected, or 3) the sliding roof is replaced or installed / removed.

If the drive gear is not reset, the AUTO function will not operate.
1. CHECK AUTO SLIDE-OPEN FUNCTION
(a) Turn the ignition switch ON.
(b) Press the sliding roof control OPEN switch for 0.3 seconds or more. Check the OPEN operation of the No. 1 and No. 2 roof glasses.
(1) When the switch is pressed, check that: 1) the No. 2 glass tilts upward, 2) the No. 1 glass tilts upward at the same time the No. 2 glass slides open, and 3 ) the No. 2 glass stops 50 mm (1.97 in.) from the fully open position.
(2) When the switch is pressed again, check that the No. 2 glass slides to the fully open position.
2. CHECK MANUAL CLOSE FUNCTION
(a) Check the CLOSE operation of the No. 1 and No. 2 roof glass.
(1) Turn the ignition switch ON.
(2) While pressing and holding down the sliding roof control CLOSE switch, check that the No. 2 glass slides to just before the fully closed position.
(3) When the switch is pressed again, check that the No. 1 glass tilts downward at the same time the No. 2 glass slides to the fully closed position.
3. CHECK SLIDING ROOF OPERATION FUNCTION AFTER IGNITION SWITCH IS TURN OFF
(a) Turn the ignition switch from ON to OFF.
(b) The sliding roof's AUTO operation function should be available for 43 seconds. However, if one of the front doors is opened during AUTO operation, the sliding roof should stop its operation immediately.
(c) Wait for 43 seconds after the ignition switch is turned OFF. Then, both the AUTO and manual operation functions should not be available anymore.
(d) With one of the front doors open, turn the ignition switch OFF. If an object is caught between the sliding roof and vehicle body and the sliding roof's jam protection function is triggered, the sliding roof should reverse its movement and stop at the fully open position.
4. CHECK JAM PROTECTION FUNCTION
HINT: When the sliding roof AUTO CLOSE and MANUAL CLOSE operation is being used (ignition switch ON or within 43 seconds of turning ignition switch OFF), the jam protection function helps prevent objects from being caught between the vehicle body and the roof glass.
CAUTION:
- Do not use a part of your body, for example your hand, or any object to check the jam protection function. Do not allow anything to become caught in the sliding roof during this procedure.
- The jam protection function may not operate with an object that is less than 5 mm (0.20 in.) in width.





(a) When the sliding roof CLOSE operation is being performed and an object is caught between the vehicle body and the roof glass, the roof glass should open a distance of 200 mm (7.87 in.) from the point of contact with the object, or open fully if 200 mm (7.87 in.) of opening distance is not available.
5. CHECK FAIL-SAFE FUNCTION
(a) If the sliding roof's jam protection function is triggered and, afterward, the sliding roof cannot be fully closed due to a malfunctioning sliding roof or a malfunctioning actuator, press and hold the CLOSE switch for at least 10 seconds. This will disable the jam protection function and the sliding roof can then be closed.
CAUTION: Be careful when closing the sliding roof glass No. 1 and No. 2 at this time.
HINT:
- Before checking the fail-safe function, make sure that there is nothing that is triggering the jam protection function.
- Pressing the CLOSE switch for 10 seconds will clear the sliding roof control ECU memory of the sliding roof's fully closed position, which disables the jam protection function.

6. CHECK SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY






(a) Disconnect the drive gear wire harness connector.
(1) Measure the voltage of the wire harness side connector.
Standard voltage:





(2) Measure the resistance of the wire harness side connector.
Standard resistance:






If the result is not as specified, there may be a malfunction on the wire harness side.
(b) Reconnect the drive gear wire harness connector.
(c) Initialize the drive gear assembly Programming and Relearning.






(d) Measure the voltage of the connector.
Standard voltage:





If the result is not as specified, replace the drive gear sub-assembly (sliding roof control ECU).
