Re: replaced battery,car will not run properly
Often if battery fails or is disconnected for a time the car will want to have readiness reset. this is best done by a tech using vadcom or vcds software , however alot of the times if there are no other problems ,taking the car for a ride for a bit will let it set readiness on it's own. let car see road speeds from 0 to about 55 mph and give it a few key cycles while driving, meaning ,stop ,park car, turn off ignition and then restart and continue driving. if it doesn't reset within 15 min or so it most likely will have another problem so watch for the mil light to come on during drive. good luck

Has to be programmed ,yes .
Body Control Module (BCM) Replacement
If the BCM is replaced, the following procedures must be performed in the subsequent order:
• BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
• Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.
A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
• The battery is fully charged.
• The ignition switch is in the ON position.
• The data link connector (DLC) is accessible.
• All disconnected modules and devices are reconnected before programming.
To setup a new BCM, access the Vehicle Control Systems in Computer/Integrating Systems menu on the scan tool to program the BCM. Select Module Replacement/Setup and follow the instructions on the scan tool.
If the BCM fails to accept the program, perform the following steps:
• Inspect all BCM connections.
• Verify that the scan tool has the latest software version.
I also have a 1999 El Dorado, with 188,000 miles. First my TCS light came on once because I was really racing the car. The car's system went into "reset mode" turning off all of the car's computer controlled functions, Starting with TCS, A/C, ABS etc. This was due to the battery or alternator failing to supply enough electrical current under extreme demands for power and performance. I ultimately had to replace my alternator $450.00. Second, I had a "Check Engine" light on because my transmission was not shifting at the proper times. The computer had to be reprogrammed then the shift pattern was fine.
You should check to see if you car's alternator is working properly by starting the car then disconnection the battery cables while it is still running. If your car still runs, then your alt is okay.
I would also have the transmission's program codes checked and reset if necessary to shift at the right time. When they hook one of those Caddy scopes to your car's main computer, it spits out a series of codes. I do not know how to read the codes, I just know that they can be changed to make the car's performance better. I hope this was helpful.
I saw what you replaced, didn't any testing? Can you tell us what testing was done?
Make sure battery has a full charge and battery connections all good. Have a helper crank it while you visually check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure. Did you use fresh gas? Also, check fuel injector pulse.
Is there a security lamp on the dash that is on or flashing? Amy applicable trouble codes?
You are going to need computer reprogrammed. A stock air filter and box are restricted air flow. With the cold airbox the vehicle is getting more air. Thus the reprogrammed of the computer is necessary to accommodate for difference.
YOU CANT REPLACE PCM AT HOME BECAUSE YOU NEED SPECIAL DIAGNOSTIC EQUIPMENT TO REPROGRAM THE NEW PCM.YOU NEED GM SCANNER THAT CAN REPROGRAM RELEARN CKP AND CMP.RELEARN IDLE AND REPROGRAM THEFT SECURITY SYSTEM.
Newer Dodge Vehicles do not have an ignition for a "metal" key. They use the Electronic Key called a FOB with a built in or integrated metal key that is only used to unlock the door. The FOB inserts into a WIN module (Wireless Ignition Module) instead of the normal igition. Reprogramming the vehicle usually does the trick however there has been significant problems with the WIN module and the dealer may have to replace it. The 2010's have a recall on some models. The manual states the keys cannot be reprogrammed. The first and easiest solution might be to try replacing the battery in the FOB (aka key),
you may disconnect the battery for a few minutes, but the correct way is to clear it with a scanner. Of course, resetting the light without the proper repairs, its just going to come back on, after the computer runs the tests and it fails.
you shouldnt have to reprogram the ecu but it wont hurt to reset it. To reset the computer take the positive cable from the car off the battery and give it 3-5min
to discharge then touch the positive cable from the car to the negative
cable (still attached to the battery) for about 5 seconds and then hook
back up the positive post and that will reset the computer. not sure how much difference it will make but like i said it wont hurn anything.
