Room Lamps
Description
The vehicle is equipped with Room Lamps located on the front and rear interior roof.
The lamps low sides are driven by the RAM, and the control logic depends on:
-
Front and rear doors status (RAM input)
-
Tailgate status
-
Lock/unlock interior lamp control information depending on RKE for vehicles not equipped with
-
Burglar Alarm (signal sent from IPM to RAM)
-
Lock/unlock interior lamp control information depending on Burglar Alarm state for vehicles equipped with Burglar Alarm (signals sent from IPM
to RAM)
-
The ignition key position (managed by the IPM and signal transmitted to the RAM).
-
The Main Room Lamp switch (variation dependent equipment), which is a common control for the interior light.
Local 3-state switches (ON, OFF and DOOR positions) directly wired to the lamps can also be used to manually force the Room Lamp behavior. The
RAM has no feedback of the local switches positions. No diagnostic (problem detection) is done on the Room Lamps.
