5. Sunroof include in comfort closure ON/OFF - When this switch is ON (up position–not
default) the CAN-IM will include the sunroof in the comfort closure.

OTTEE:: DO N
NO
OTT set this switch to ON if the car is not equipped with sunroof or improper function of the
central locking system may result.
Bi-Color LED
The CAN-IM has one bi-color LED that will visually report the status of the initialization routine
and the active/inactive status of the module. The operation and interpretation of the LED colors is
described in the next section.
Powering Up the CAN-IM
After power-up, the CAN-IM must first always reads the CAN bus of the vehicle in order to identify
if the type of the car is compatible with the firmware of the module.
During the initialization phase the CAN-IM will perform the following steps:
➤
➤
Checks if an internal ( hardware or software ) error occurred: if true, illuminate the LED red for
5-seconds and then extinguish the LED (this is an unusual occurrence).
➤
➤
Checks if the platform of the car is recognized (max 3-sec); if not, illuminate the LED red for
2.5-sec and then extinguish the LED.
➤
➤
Waits indefinitely for the ignition to be ON and during this time flashes the LED green for 100
msec at 3-sec intervals.
➤
➤
Waits 3 times (max 4-sec each) after ignition on for all relevant messages to be detected on the
bus and during this time flashes the LED green rapidly (130ms ON, 130 ms OFF); if not,
illuminate the LED red for 2.5-sec and then extinguish the LED.
➤
➤
Waits a maximum of 4-sec after the detection phase for the convenience computer in the car to
be programmed according to DIP switches 1,2 and 5 and for proper operation of CAN-IM
module; if not successful it returns to the second step; if successful it illuminates the LED green
for 2.5 sec and exits the initialization phase (enters normal operation in which it reads and
broadcasts on the CAN bus).
If DIP switch 1,2 or 5 (5 only if OFF to ON) are changed during normal operation and the ignition
is turned On, then the programming of the convenience computer in the car is done again. The
