INSTALLATION
For installation, reverse removal procedure, noting following
points.
Align positioning holes in sliding roof assembly at right and left
and pins on body side for installation.
Connect drain hoses to sliding roof assembly at 4 locations. Pass
front drain hose between roof panel and inner panel and through
front pillar down to sill side. Pass rear drain hose into baring hole
in rear quarter inner panel and through C pillar down to jig hole
in rear side bumper.
NOTE:
After reinstalling sliding roof assembly, be sure to make
glass adjustment. (Refer to SLIDING ROOF GLASS ADJUST-
MENT described previously.)

DIAGNOSIS
WARNING:
To avoid deployment when troubleshooting the air bag system, do not use electrical test equipment
such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electrical equipment
other than that specified in this manual. Do not use a non-powered probe type tester.
Instructions in this manual must be followed carefully, otherwise personal injury may result.
DIAGNOSTIC TROUBLE CODES
The ªAir Bag Diagnostic System Checkº must always be the starting point of any air bag system diagnosis. The
ªAir Bag Diagnostic System Checkº checks for proper ªAIR BAGº warning lamp operation and checks for air bag
diagnostic trouble codes using the Tech-1 (scan tool) or on-board diagnosis function.
Current diagnostic trouble code ± Malfunction that are presently being detected.
History diagnostic trouble code ± All malfunction detected since the last time the history memory was cleared.
USE OF SPECIAL TOOLS
WARNING:
To avoid deployment when troubleshooting the air bag system, do not use electrical test equipment
such as a battery powered or AC powered voltmeter, ohmmeter, etc., or any type of electrical equipment
other than that specified in this manual. Do not use a non-powered probe type tester.
Instructions in this manual must be followed carefully, otherwise personal injury may result.
You should be familiar with the tools listed under ªSpecial Toolsº in this section. You should be able to measure
voltage and resistance. You should be familiar with proper use of a scan tool such as the Tech-1 Diagnostic Com-
puter, Driver/Passenger Load Tool, Connector Test Adapter Kit and the Digital Multimeter.
Special Tool (Connector Test Adapter Kit)
(A): 09932-76010
This must be used whenever a diagnostic procedure requests
checking or probing a terminal.
Using the appropriate adapter in the special tool will ensure that no
damage to the terminal will occur from the multimeter probe, such
as spreading or bending.
The adapter will also give an idea of whether contact tension is suffi-
cient, helping to find an open or intermittent open due to poor termi-
nal contact.
