Operation
1.“AUTO TRIG ”

While trying to detect the DTC/1st trip DTC by performing the DTC Confirmation Procedure, be sure to
select to “DATA MONITOR (AUTO TRIG) ” mode. You can confirm the malfunction at the moment it is
detected.

While narrowing down the possible causes, CONSULT-II should be set in “DATA MONITOR (AUTO
TRIG) ” mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, compo-
nents and harness in the DTC Confirmation Procedure, the moment a malfunction is found the DTC/1st
trip DTC will be displayed. (Refer to “INCIDENT SIMULATION TESTS” in GI-28, "
How to Perform Effi-
cient Diagnosis for an Electrical Incident" .)
2. “MANU TRIG ”

If the malfunction is displayed as soon as “DATA MONITOR ” is selected, reset CONSULT-II to “MANU
TRIG ”. By selecting “MANU TRIG” you can monitor and store the data. The data can be utilized for fur-
ther diagnosis, such as a comparison with the value for the normal operating condition.

Diagnostic test modeFunction
Service $01 READINESS TESTS This diagnostic service gains access to current emission-related data values, including
analog inputs and outputs, digital inputs and outputs, and system status information.
Service $02 (FREEZE DATA) This diagnostic service gains access to emission-related data value which were stored by
ECM during the freeze frame. For details, refer to
EC-53, "
FREEZE FRAME DATA AND
1ST TRIP FREEZE FRAME DATA" .
Service $03 DTCs This diagnostic service gains access to emission-related power train trouble codes which
were stored by ECM.

TILT UP OPERATION
When the tilt switch is operated for tilt up, ground is supplied

to sunroof motor assembly terminal 4

through sunroof switch terminal 4

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will tilt up.
TILT DOWN OPERATION
When the tilt switch is operated for tilt down, ground is supplied

to sunroof motor assembly terminal 10

through sunroof switch terminal 6

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will tilt down.
SLIDE OPEN OPERATION
When the switch is operated for slide open, ground is supplied

to sunroof motor assembly terminal 9

through sunroof switch terminal 3

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will slide open.
SLIDE CLOSE OPERATION
When the switch is operated for slide close, ground is supplied

to sunroof motor assembly terminal 3

through sunroof switch terminal 1

through sunroof switch terminal 2

through sunroof motor assembly terminal 8

through grounds M57, M61 and M79.
Then, the sunroof will slide closed.
RETAINED POWER OPERATION
When the ignition switch is turned to OFF position from ON or START position, power is supplied for 45 sec-
onds.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-II. Refer to RF-16, "
CONSULT-II Function (BCM)" .
MEMORY RESET PROCEDURE
To reset the sunroof motor memory from any sunroof position (full open, partially open, closed, partially
vented, and vented), push and hold the sunroof tilt switch in the forward (DOWN) position until the sunroof is
fully closed. After it has closed all the way, push and hold the tilt switch forward (DOWN) for more than 2 sec-
onds to re-establish the motor preset position. The sunroof should now operate normally.
INTERRUPTION DETECTION FUNCTION
The CPU (central processing unit) monitors the sunroof motor operation and the sunroof position (fully-closed
or other) by the signals from the sunroof motor.
When sunroof motor detects an interruption during the following sliding close operations, sunroof switch con-
trols the motor for open and the sunroof will operate until it reaches full open position.

automatic close operation when ignition switch is in the ON position.
