What cause the electronic control module to stop working. Recently, I had to have my battery disconnected and inspected by a secret service worker before entering a secured area and since then before

Put it back the way it was , led lights are causing the problem . Head lamps are controlled by LCM-lighting control module -your messing with electronics inside .

Lighting Control Module (LCM)
The LCM eliminates the electronic interference and heat associated with the thermoelectric devices used previously. The LCM is a microprocessor based module that controls several vehicle subsystems. It responds to electrical input signals from various switches, sensors, and external modules.
LCM exterior lighting subsystem functions include:

• Headlamps with autolamps
• Turn signal lamps/hazard flasher lamps
• Cornering lamps
• Parking lamps
• Battery saver

Congrats, you have found Ford's super secret fuse that drove everyone mad for years!

There could be several reasons why your 2007 Dodge Grand Caravan sliding door is not latching properly. Here are some possible causes:

1. Obstruction in the Door Track: Check the door track for any debris, dirt, or foreign objects that may be blocking the door from closing fully. Clean the track and remove any obstructions.
2. Broken or Misaligned Door Hinges: If the door hinges are damaged or misaligned, the door may not close properly. Inspect the hinges for any signs of damage or wear and replace them if necessary.
3. Damaged Latch or Actuator: The latch or actuator that holds the door in place may be damaged or malfunctioning, preventing the door from closing properly. Inspect the latch and actuator for any signs of damage and replace them if necessary.
4. Dead Battery: If the battery in your Dodge Grand Caravan is weak or dead, the electronic functions of the sliding door may not work properly. Check the battery and replace it if necessary.
5. Faulty Door Control Module: The sliding door may be controlled by a door control module, which may be faulty or damaged. Have the control module tested and replaced if necessary.

In any case, it's recommended that you take your vehicle to a certified mechanic or dealership to diagnose and fix the issue, especially if you are unable to get the door closed manually.

What make , model an year vehicle ? Disconnecting the battery resets what ever controls the central locking system an power windows . Could be a control module of some kind or a sticking relay maybe . You in the states ? You could go to http://www.bbbind.com/free_tsb.html free wiring diagrams to see what controls these thing's . You mite also have modules on the vehicle checked for DTC'S - diagnostic trouble codes . Could have a BCM - body control module , GEM - generic electronic module etc....

The electronic's , control modules , driver door electronic control module ,the lighting control module , SCP serial data communication network . You have no way of fixing this . A factory scan tool would be needed to check communication on the SCP data network .

010 Ford SCP Communications
You would need factory service info. to find control moduels , there power an ground circuits to do electrical testing . Voltage drop testing etc....
You could very easily make thing's worst , short out the network an the vehicle will do nothing . You have no idea of the complexity of this .

Battery Disconnect or Replacement Problems
Listen under the hood in engine compartment , see if maybe your mistaken . Disconnecting the battery could cause Electronic throttle control to cycle the throttle plate , DC electric motor on the throttle body . Without hearing for myself ,that's the best i can come up with . Looking at factory service info. ,wiring harnesses , relay's , control modules . I don't see anything behind the instrument panel that could cause a buzzing

Disconnect the battery from car terminals, wait for 10 minutes, and reconnect back the battery, in order to reset the electronic control module.
If this procedure will not help you need to access the electronic control module using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code. Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the electronic control module.

Interior lights are controlled by the Body Control Module (BCM)
The door jam switches input to the BCM is a door is open or closed.
You may have a door jam switch that is sticking or coroded, causing the
lights to do this, or a BCM acting up.
Remove the door jam switches and inspect. Disconnecting the switches
should make the lights to go out...Hope this helps.

Removing the battery connection for this procedure will cause diagnostic trouble codes to be stored in the engine control module. Erasing these DTCs and resetting the readiness code will require Volkswagen scan tool VAG1551/1552 or equivalent. The same results will occur when disconnecting engine management components while the key is in the on position. Some driveability problems may be noticed until the system re-adapts to operating conditions. OBD II readiness codes, which may be required for emissions testing, may also be erased. Convenience electronics (alarm systems, interior light control, power locks, mirrors, and windows) may need to be re-set using a VAG 1551/1552 or equivalent sacan tool.

BMW has the central body electronic zkev system.its computer control or control by a control module .if you replace battery or move battery.it put wipers in sleep mode.the BMW dealers is going to have to reset it to get wiper going again.
