DOUBLE LOCK FUNCTION DOES NOT OPERATE PROPERLY
CIRCUIT DESCRIPTION
RHD Models w/ Double Lock Only:
All the doors except the back door have the double locking system. This\
system is set and unset by the
integration relay. When the integration relay receives a request signal from the wireless transmitter (See
page 73±1) to set or unset the double locking system, it drives the double lock \
motor built into each door
lock according to the condition of all the double lock position switches, th\
us causing the double locking sys-
tem to be set and unset.
