It should tell you which one .
Driver Door Ajar Malfunction
Passenger Door Ajar Malfunction
If not a scan tool would be the best way.
Ignition ON, observe the scan tool Driver Door Ajar Sw parameter while opening and closing the driver door. The parameter should change between Door Closed and Door Ajar
? If the parameter does not change, refer to Driver Door Ajar Malfunction.
With the passenger doors closed, observe the scan tool Door Ajar Switch parameter while opening and closing each door. The parameter should change between Door Closed and Door Ajar.
? If the parameter does not change, refer to Passenger Door Ajar Malfunction

Ignition OFF, disconnect the harness connector at the driver door latch.
Test for less than 5 ohms between the ground circuit terminal 8 and ground.
? If greater than the specified range, test the ground circuit for an open/high resistance.
Ignition ON, verify the scan tool Driver Door Ajar Sw parameter is Door Closed.
? If not the specified value, test the signal circuit terminal 6 for a short to ground. If the circuit tests normal, replace the BCM.
Install a 3A fused jumper wire between the signal circuit terminal 6 and the ground circuit terminal 8. Verify the scan tool Driver Door Ajar Sw parameter is Door Ajar.
? If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
If all circuits test normal, test or replace the driver door latch

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 .

Where is my door chime located impala 2002


It comes through the radio an left front speaker .
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the left front speaker. The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The Multifunction Alarm generates the audible warnings on vehicles with RPO UL5 -- Radio Delete Option. The following lists the audible warning priority and the pulse rate:
The radio activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a class 2 message to the radio indicating the chime frequency of a medium rate and at a continuous duration. The door ajar warning sounds and the door ajar indicator illuminates when the following occurs:
  1. The body control module (BCM) determines that the driver's door is open and the signal circuit low. The IPC receives a message via class 2 from the BCM requesting illumination of the door ajar indicator.
  2. The vehicle is not in park. The BCM receives a class 2 message from the PCM indicating the gear position.
Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate and share data with each other:
?€¢
Auxiliary Power Drop Connector


?€¢
Body Control Module (BCM)


?€¢
Driver Information Center (DIC)


?€¢
Electronic Brake Control Module (EBCM)


?€¢
Instrument Panel Cluster (IPC)


?€¢
Powertrain Control Module (PCM)


?€¢
Radio


?€¢
Remote Playback Device-CD Player (if equipped with UQ3)


?€¢
Inflatable Restraint Sensing and Diagnostic Module (SDM)


?€¢
Vehicle Interface Unit (VIU) (if equipped)

The class 2 serial data link allows a scan tool to communicate with the above modules for diagnostic and testing purposes.

Aside from Driver Window Switch, where can I find a RAP-OFF wire Gray/Black in a 2012 Equinox?


Each door ajar switch sends a signal. The signal goes through the window switch for that door, probably be easiest to access the ajar signal wire at the window switch connector on any door.

Liftgate door ajar warning light


Have someone stand at liftgate and press the switch in. If the warning goes off, then your switch just needs adjusting or the small flat block that acts like your partners finger is missing or misaligned. The door hinge pins should not be a problem unless there is damage to the area or a teenager was using the door as a tarzan swing. The BCM is a possibility (rare), but it is much more likely a contact problem behind the switch - ie. a loose connection, chaffed wire or short. Good luck.

2005 jeep wrangler when i turn lights on beeping starts


did you RTM read the operators guide yet,
it tells you why all beeps beep and what lamps flash, (warning) and why. did you?
you turn on, the head lights, (what about 1st click , parking lights"?)
and does the dash cluster, show warnings of any kind?

if a door is ajar the system will think, you are exiting veh. with lights on and tell you, buy beeping ,etc.
but on my jeep it says on the dash DOOR, or on EVICs, (not yours)
the newer car even tells what door IS AJAR.
mine on shows , "DOOR"
the operator guide will say, check all doors for ajar, and get warning clear before driving....etc.

if you lost the guide here it is for free

http://justgivemethedamnmanual.com/jeep/jeep-wrangler-owners-manuals/

click the 05 link
ignore beeps, there are just too many .. i look at the cluster and learn to read it..
my newer jeep 08 can produce 1000s of errors,,,,, possible.
in fact the intent it to beep to tell the driver to look at the cluster
for in depth, causes.
see chapter starting on page 136'

once sound it makes is Check gauges chime. so check them.
and headlamps left on
and door ajar.

page 63
NOTE: If the driver's door is left open, and the headlights
or parking lights are left on, the "High Beam
Indicator Light" will flash and a chime will sound.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned off, a chime will sound when the driver's door

its a crude system, and evolved to complex in 2007.
"DOOR" or RF-door , on mine.
or

NOTE: A tone will chime if the turn signals are left on
for more than 1 mile (2 km).

Door ajar warning


This is caused by one of the many door sensor switches being defective. You can tear all the door apart and replace all the switches or have the dealer scan the body control module and quickly pinpoint the bad switch.,

Frequently the door ajar alarm will not turn off even after you close the door .


{: ) Some models use the front doors only, others use all doors for any ajar signals, and may even indicate a message on the DIC that a door is ajar or open. You can try to slam the doors one by one to get that real tight closed door and you may manually make the adjustments.
However if there are wiring or components issue, it can take you long time to search and diagnose. Using a scan tool is the fastest way to locate the main cause.
The three most possible and common cause are the doorlatches, improper adjustments, and shorted signals on the wirings.
