Toyota Tacoma 2015-2018 Service Manual: Initialization

INITIALIZATION

1. INITIALIZE SLIDING ROOF SYSTEM

NOTICE:

  • Before starting this operation, make sure that the guide rails are not deformed and there is no foreign matter on the guide rails.
  • When the sliding roof glass sub-assembly or sliding roof drive cable sub-assembly is adjusted or removed/installed, or the sliding roof drive gear sub-assembly is replaced, the sliding roof ECU (sliding roof drive gear sub-assembly) must be initialized (pulse sensor initial position setting). If initialization is not performed, the auto operation, jam protection function, key-off operation, key-linked function, wireless transmitter-linked function and sliding roof open warning may not operate, or the sliding roof may move in reverse or become misaligned.
  • During initialization, do not apply a physical shock, such as opening/closing a door or driving the vehicle at 5 km/h (3 mph) or more, to the vehicle and do not perform any electrical operations.

HINT:

The sliding roof switch assembly is attached to the roof console box assembly.

(a) Perform initialization according to the table below.

Condition of Sliding Roof

Proceed to

Auto slide open and close/tilt up and down functions do not operate.

Procedure A

Automatically moves, but the sliding roof glass does not stop at the correct position (misalignment occurs), or the sliding roof glass moves in the reverse direction during tilt down operation.

Procedure B

Automatically moves, but the sliding roof glass moves in the reverse direction during slide close operation.

Procedure C

(1) Procedure A

  1. Turn the ignition switch to ON.
  2. Fully close the sliding roof glass and release the sliding roof switch.
  3. Press and hold the CLOSE or UP switch.

    NOTICE:

    Press and hold the CLOSE or UP switch until step 5 is completed. If the switch is released before step 5 is completed, repeat the operation from step 2.

  4. Sliding roof glass moves in the following order: tilts up → 1 second pause → tilts down → slides open → slides closed.
  5. After the roof glass stops in the fully closed position, release the switch.

    HINT:

    The initialization process ends when this operation completes.

  6. Make sure that the sliding roof auto function operates normally.

(2) Procedure B

  1. Turn the ignition switch to ON.
  2. Press the UP switch to move the sliding roof glass to the fully tilted up position and then release the UP switch.

    HINT:

    • If the sliding roof glass cannot be fully tilted up due to misalignment of the roof glass, press and hold the CLOSE switch until the sliding roof glass stops closing, and then press and hold the UP switch until the sliding roof glass stops tilting up.
    • If the sliding roof glass moves in the reverse direction while it is being closed, repeatedly tap the CLOSE switch at short intervals to fully close the sliding roof glass. When the sliding roof glass is fully closed, press the UP switch to move the sliding roof glass into the fully tilted up position.
  3. Press and hold the UP switch again until the following operations complete: pauses for approximately 10 seconds or more → tilt inching motion → 1 second pause → tilts down → slides open → slides closed.

    NOTICE:

    • Press and hold the UP switch until step 4 is completed.
    • While performing step 3, if the UP switch is released before "pauses for approximately 10 seconds or more" completes, start this step over.
    • While performing step 3, if the UP switch is released after "pauses for approximately 10 seconds or more" completes, but above movements complete, perform procedure A to initialize the position of the sliding roof glass.
  4. After the roof glass stops in the fully closed position, release the switch.

    HINT:

    The initialization process ends when this operation completes.

  5. Make sure that the sliding roof auto function operates normally.

(3) Procedure C

  1. Turn the ignition switch to ON.
  2. Press and hold the CLOSE switch to move the sliding roof glass in the following order: slides closed → moves in the reverse direction → pauses for approximately 10 seconds or more → slides closed → tilts up → 1 second pause → tilts down → slides open → slides closed.

    NOTICE:

    • Press and hold the CLOSE switch until step 3 is completed.
    • While performing step 2, if the CLOSE switch is released before "pauses for approximately 10 seconds or more" completes, start this step over.
    • While performing step 2, if the CLOSE switch is released after "pauses for approximately 10 seconds or more" completes, but before the above movements complete, perform procedure A to initialize the position of the sliding roof glass.
  3. After the roof glass stops in the fully closed position, release the switch.
