Mariner 2WD V6-3.0L (2008)
the dimmer switch is rotated to the top (dome) detent. The interior lights are activated by other interior lighting features when the dimmer switch is
positioned in the dimming control range. The courtesy lights are kept off when the dimmer switch is rotated to the bottom (dome) detent.
Interior Lighting Delay
The interior lighting delay feature provides temporary illumination of the courtesy lamps after the doors are opened and then closed. The interior
lighting delay feature keeps the courtesy lamps on for a period of 25 seconds. If during the 25-second delay time the SJB detects that the ignition has
been turned to RUN, ACC, START, or if the vehicle is locked using the remote keyless entry (RKE) transmitter, the courtesy lamp illumination is
discontinued.
Illuminated Entry
The illuminated entry requests the courtesy lamps to illuminate when the ignition is OFF and the RKE transmitter UNLOCK button is pressed. The
illuminated entry requests the courtesy lamps off after 25 seconds have elapsed, the ignition is switched to ON, or when the RKE transmitter LOCK
button is pressed.
Illuminated Exit
The illuminated exit requests the courtesy lamps illuminate for 25 seconds when all doors are closed and the ignition key is removed from the ignition
lock cylinder. The illuminated exit deactivates when any door becomes ajar, the ignition key is inserted into the ignition lock cylinder, or 25 seconds
have elapsed.
Theater Lighting
The theater lighting feature ramps-up the courtesy lamps over 0.7 second when courtesy lamp activation is requested. The theater lighting feature
ramps-down the courtesy lamps over 1.7 seconds when interior lighting deactivation is requested by any feature other than the panic alarm or the
battery saver.
Interior Lamp Arbitrator
The interior lamp arbitrator (located in the SJB) chooses between the interior lighting, the interior mode, the interior lighting delay, the illuminated
entry, the illuminated exit, the battery saver, and the alarm flash processing to determine which feature has precedence of activating and deactivating
the interior lamps.
The features are prioritized as follows:
-
Alarm flash processing
-
Battery saver
-
Interior mode
-
Interior lighting
-
Interior light delay
-
Illuminated entry
-
Illuminated exit
Battery Saver
The battery saver is internal to the SJB and provides automatic shut-off of the demand lamps (cargo lamp, vanity lamps, map lamps) and courtesy
lamps after a time-out period in order to save battery voltage. A timer in the SJB is started when the ignition is turned to the OFF position. When the
time-out period for the lamps has elapsed, the voltage is automatically shut off to the lamps by the battery saver. While the battery saver has voltage
disabled, if the ignition is turned to any position other than OFF, the key is removed from the ignition cylinder, the dome lamp switch is turned to the
ON position, any door becomes ajar, any button, except the LOCK button, of the RKE transmitter is pressed, or a valid entry code is entered on the
keypad, the battery saver restores voltage and starts the timer again.
NOTE: Time out is 1 minute if the vehicle has less than 80 km (50 miles).
The battery saver time-outs are as follows:
-
Courtesy lamps = 10 minutes
-
Demand lamps = 10 minutes
Field-Effect Transistor (FET) Protection
The SJB utilizes a FET protective circuit strategy for many of its outputs (for example, the headlamp output circuit). Output loads (current level) are
monitored for excessive current (typically short circuits) and are shut down (turns off the voltage or ground provided by the module) when a fault is
detected. A continuous DTC is stored at that time for the fault. The circuit then resets after a customer demand of the function (switching the
component on, battery saver being energized). When an excessive circuit load occurs several times, the module shuts down the output until a repair
procedure is carried out. At the same time, the continuous DTC that was stored on the first failure will not clear by a command to clear the continuous
DTCs. The module will not allow this code to be cleared or the circuit restored to normal until a successful on-demand self-test proves that the fault
has been repaired. After the on-demand self-test has successfully completed (no on-demand DTCs present), the continuous DTC will have been
cleared and the circuit function returns.
Each circuit has three predefined levels of short circuit tolerance established in the module based on each circuits' capability. When the first or second
level is reached, the continuous DTC associated with the circuit sets along with DTC B106E. These DTCs may be cleared using the Clear DTC
operation on the scan tool as long as the fault itself has been corrected. If any of the circuits are shorted past the third level, then B106F sets along
with the associated continuous DTC. This DTC cannot be cleared and the module must be replaced.
