Sun Roof / T-Top / Convertible Top

General Description

Power Sliding (Sun) Roof System Description

S6JB0A9901001

The controller is included in the sliding roof motor unit.
The sliding roof functions are controlled with the sliding roof position data. Sliding roof position and sliding direction are 
detected by the controller referring to pulse signals from motor.
Initialization of the sliding roof position data is required in the following situation to reset anti-pinching function: battery 
cable or motor connector is disconnected since the sliding roof position data is deleted without power supply to the 
motor. Refer to “How to reactivate the system to prevent being pinched by the sunroof” in Sunroof section of Owner’s 
manual to initialize the sliding roof position data.

Sliding (Sun) Roof Glass Removal and 
Installation

S6JB0A9906002

Removal

1) Open sunshade (1) fully and tilt up sliding roof.

2) Disconnect negative (–) cable at battery.
3) Remove sliding roof covers.
4) Remove sliding roof glass by removing bolts 

(TORX

® T25) (1).

Installation
For installation, reverse removal procedure, noting the 
following points.

1) Tighten glass fixing bolts temporarily.
2) Initialize sliding roof position data referring to 

Owner’s Manual.

3) Position sliding roof glass by closing sliding roof 

glass completely.

4) Tighten glass fixing bolts after sliding roof glass 

adjustment referring to “Sliding (Sun) Roof Glass 
Adjustment”.

Sliding (Sun) Roof Glass Adjustment

S6JB0A9906003

1) Loosen sliding roof glass fixing screws (at 4 

locations) and move sliding roof glass (1) up and 
down 2 to 3 times. In this way, sliding roof glass can 
be positioned in both vertical and horizontal 
directions by elasticity of sliding roof weather strip.

2) Position sunroof glass by such dimensions with 

respect to roof panel surface as specified below.

Sliding roof glass position (between glass roof 
and roof panel)
“a”: 0 mm (0.0 in.)

3) After installing all parts and adjusting properly, check
