Toyota Tacoma (2015-2018) Service Manual: Sliding Roof does not Move by Operating Sliding Roof Control Switch
DESCRIPTION
The sliding roof ECU (sliding roof drive gear sub-assembly) receives slide and tilt signals when the sliding roof switch is operated and drives its built-in motor.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
- When the sliding roof ECU (sliding roof drive gear sub-assembly) is
removed and reinstalled or replaced, the sliding roof ECU (sliding roof
drive gear sub-assembly) must be initialized (See page
.gif)
). - The sliding roof system uses the LIN communication system. First, confirm
that there are no malfunctions in the LIN communication system. Refer to
the How to Proceed with Troubleshooting procedure (See page
).
- When a sliding roof ECU (sliding roof drive gear sub-assembly) DTC is output, first perform troubleshooting for the sliding roof ECU (sliding roof drive gear sub-assembly) DTC.
