Toyota Tundra Service Manual: Operation Check

OPERATION CHECK

HINT:

When pressing the switch for less than 0.3 seconds, the roof 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 switch to open for 0.3 seconds or more. Check that the roof glass automatically slides until it is fully opened.

(c) When the roof glass is fully open, press the SLIDE switch to close for 0.3 seconds or more. Check that the roof glass automatically slides until it is fully closed.

(d) When the roof glass is fully tilted up, press the TILT switch to down for 0.3 seconds or more. Check that the roof glass automatically slides until it is fully tilted down.

(e) When the roof glass is fully tilted down, press the TILT switch to up 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 switch stops the roof glass operation.

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 approximately 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 PROTECTION 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:

• Set a thick book wrapped with a shop rag or piece of cloth near the sliding roof fully closed position.
• If the jam protection does not operate, reset the sliding roof drive gear (motor).

(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.

(b) When the TILT UP / DOWN function is operating, and an object is caught between the vehicle body and the roof glass, check that the sliding roof tilts up fully.

4. CHECK KEY-LINKED OPERATION FUNCTION (DRIVER'S DOOR ONLY)

HINT:

The sliding roof's key-linked operation can be customized to perform either the sliding roof sliding operation or tilting operation.

(a) Insert the key into the driver side door's key lock cylinder, and turn the key to the UNLOCK position for approximately 3 seconds or more. Check that the sliding roof starts moving (SLIDE OPEN / TILT UP operation). Then release the key and check that the sliding roof stops moving.

(b) Insert the key into the driver side door's key lock cylinder, and turn the key to the LOCK position for approximately 3 seconds or more. Check that the sliding roof starts moving (SLIDE CLOSE / TILT DOWN operation). Then release the key and check that the sliding roof stops moving.

5. CHECK DEFLECTOR OPERATION

(a) Check that the sliding roof automatically deflector UP / DOWN depending on the vehicle speed.

(1) Conditions that enable the sliding roof to automatically deflector DOWN:

• Sliding roof in fully open or UP position
• Vehicle speed 75 km/h (47 mph) or less (during acceleration)

(2) Conditions that enable the sliding roof to automatically deflector UP:

• Sliding roof in fully open or DOWN position
• Vehicle speed 65 km/h (40 mph) or less (during deceleration)

6. CHECK FAIL-SAFE FUNCTION

(a) If the sliding roof does not close because the jam protection function operates improperly, press the TILT switch to up and hold it for 10 seconds or more. Then the sliding roof glass will be fully tilted up. (It goes down a little after it is fully tilted up.) Then, you can manually close the sliding roof.
