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.

CHECK AUTO SLIDE-OPEN/CLOSE FUNCTION
1. Check the AUTO slide OPEN operation function.
  1. Turn the ignition switch ON.
  2. If the roof glass is not fully closed, slide or tilt it so that it is fully closed.
  3. With the roof glass fully closed, press the slide roof motor OPEN switch for over 0.3 seconds. The roof glass will begin open through the AUTO operation and stop 35 mm (1.38 in.) from the fully open position. If the switch is pressed again, the roof glass will fully slide open.
2. Check the AUTO slide CLOSE operation function.
  1. Turn the ignition switch ON.
  2. Press the sliding roof motor CLOSE switch for 0.3 seconds or more. The roof glass should automatically close.
  3. If the CLOSE or OPEN switch is pressed while the roof glass is in motion, the roof should stop moving.
CHECK JAM PROTECTION FUNCTION
HINT:

When the sliding roof AUTO operation is being used, the jam protection prevents objects from being caught between the vehicle body and the roof glass.

Operates during:

AUTO CLOSE operation
CAUTION:
- Do not use a part of your body, for example your hand, or any object to check the jam protection. Do not allow anything to become caught in the sliding roof in this procedure.
- The jam protection function may not operate with an object that is less than 5 mm (0.20 in.) in width.
1. 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.

CHECK FAIL-SAFE FUNCTION
1. If the sliding roof does not close because the jam protection function operates improperly, press the slide roof motor switch on the SLIDE/OPEN side and hold it until the sliding roof is fully slide open. Then, you can manually close the sliding roof.

CHECK SLIDING ROOF DRIVE GEAR SUB-ASSY

Disconnect the drive gear connector.
Measure the resistance and voltage of the wire harness side connector.

Standard:

STANDARD CONDITION

Tester Connection	Condition	Specified Condition
5 (+B) - Body ground	Always	10 to 14 V
8 (IG) - Body ground	Ignition switch OFF	Below 1 Ω
8 (IG) - Body ground	Ignition switch is in ON	10 to 14 V
9 (OPEN/DOWN) - Body ground	Sliding roof motor switch ON	Below 1 Ω
10 (CLOSE/UP) - Body ground	Sliding roof motor switch ON	Below 1 Ω

If the result is not as specified, there may be a malfunction on the wire harness side.

Reconnect the drive gear connector.
Initialize the sliding roof gear (see INITIALIZATION ).

Measure the voltage of the connector.

Standard:

STANDARD CONDITION

Tester Connection	Condition	Specified Condition
9 (OPEN) - Body ground	Ignition switch ON and OPEN switch ON	O V
9 (OPEN) - Body ground	Ignition switch ON and OPEN switch OFF	10 to 14 V
10 (CLOSE) - Body ground	Ignition switch ON and CLOSE switch ON	O V
10 (CLOSE) - Body ground	Ignition switch ON and CLOSE switch OFF	10 to 14 V

If the result is not as specified, the drive gear sub-assy (sliding roof control ECU) may have a malfunction.
