SOURCE: door ajar light won't go off

I had the same problem. Spray WD-40 (with the sprayer extender) into the latch of the doors very liberally. Open and close doors a few times. Should resolve issue.

Rear hatch keeps opens while driving...


Unless you have electrical diagnostic skills , I suggest you take this to the dealer ! The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the liftgate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch.
The body control module (BCM) receives an input from the liftgate ajar assembly. The ajar assembly is normally open when the liftgate is fully closed. When the liftgate is opened, the ajar assembly contacts close providing a path to ground. The driver information center (DIC) illuminates the rear access open message when the gate is open. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the liftgate ajar status. If this message is displayed and the vehicle speed is greater than 8 km/h (5 mph), a chime will sound.
It could be ajar switch is bad .

The alarm goes off by itself..I am no where near the key


very old post... choices?? i will try to help others fix ALARMS.
Jeep WK. 2005 to 2010
what id do? , is never set it. or defeat it. (ask)( the oper,guide tells this)

but if it MUST work than it must be fixed.
the dealer would use a scan tool , see no errors and replace something exensive, then it fails again. the endless story of alarms.
in your case he'd install the TSB fix first.
He'd use a DRBIII scan tool to find the offending input.
The BCM (body puter ) gets the sensor inputs belowL

The BCM receives the ajar switch signals on the following circuits.
  • Circuit G75 provides left front door ajar switch signal
  • Circuit G74 provides right front door ajar switch signal
  • Circuit G77 provides left rear door ajar switch signal
  • Circuit G76 provides right rear door ajar switch signal
  • Circuit G78 provides liftgate ajar and liftglass ajar signals.
the hardest problems are always intermittants.
Intermittent alarms and stalling engines, tops list.
finding it? , with out sleeping in the car is a big problem.

also there is TSB on this.
Swing gate open alarm.
http://www.jeepforum.com/forum/f67/2008-wk-liftgate-open-message-746268/#post13865598

the hard part, is finding out which inputs is (was) failing.
in my car i can find it with a scan tool .
newer cars store the failed input in the PCM memory. as a DTC.

In my shop I have a CAN-BUSS monitoring tool that allows me
to see live AJAR messages and logs them to the laptop, HDD.
for later analysis. (ok the lift gate failed at 3am, bingo)
my 2008 logs, DTCS like this.
B1820-HOOD AJAR INPUT CIRCUIT HIGH (and all others)
i have a scan tool that can see that , called a innova 3160
a $200 tool,
I have 2 ways to find intermittent in my newer jeep

FSM quotes with comments.
VTSS VERIFICATION TEST - 1A Diagnostic Test
1. Perform VTSS Verification Test
  • Open the driver door and roll down the window.
  • Remove the ignition key (but keep in hand).
  • Lock the doors with RKE transmitter or power door lock switch.
  • Ensure all doors, tailgate, and tailgate flip-up glass are closed.
  • If the VTSS Indicator Lamp flashes rapidly and after approximately 16 seconds changes to a slower flash, the system is operational. However, If the indicator fails to flash as described, there is a problem with the system.
  • comment: gee, attempt to rattle all doors, and see if VTSS sees a failure. all doors, lift gate and hood, (if car has hood switch)
the FSM shows the B1xx and B2xxx codes for alarms.
only a scan tool can do that. mine can,
you can also rent cheap CAN-BUS scan tools, from most good
autostores.
that should cover most alarming issues.
but here is one better for older jeeps.

Battery on 98 Ford Expedition doesn't hold charge


First thing I would do is have someone qualified disconnect the alarm and stereo and start over.
Chances are you have circuits cross-connected and something is draining the battery.

1998 Ford Ranger Battery keeps draining when vehicle sits (any


Sounds like something is shorting out but first I would not trust that the battery is good . So try unhooking the battery after its been charged and then hooking it up the next morning to see if it will start your truck and if it works the battery is good and need to find the short but if it is drained and dont start truck its a bad battery.

I am unable to turn off door courtesy lights even after disconnecting lift gate ajar switch. Does new switch have to be in place to turn off lights?


I haven't picked up the part yet but it should be in tomorrow. According to a tech update from Chrysler in 1997, the rear hatch door has a door ajar switch in the handle and for, at least, the 95's and 96' switch;s were getting wet and corroding at the contacts. Unless this switch sends a signal to the computer, telling it that the door is closed, the courtesy lights stay on and drain the battery.
I hope that this part will fix the problem and I will let you know how it came out. I'll have to replace the battery also.

When driving the vehicle the interior lights flash on and off the power locks flutter and the door ajar chimes.


Check the rear lift gate switch. Or it could be that one of the doors or the rear lift gate is out of adjustment and not closing tightly. Try closing all doors and lift gate then from the outside push in on the doors and see if they go in. If it is the doors , when you push on the one that is causing the problem the door ajar chime will stop .

LIFTGATE AJAR LIGHTS UP


the problem is the lift-gate ajar/courtesy light switch that is located on the left and right latch assemble of the lift gate, they stick and cause this concern, there are numerous technical service bulletins from Ford about this, have replaced at least 100. PS, washing the engine had nothing to do with it, u can try using spray lube on the latch's and open and close the gate repeatably to see if the switch un-sticks.
