Question about 1989 Dodge Dynasty

1 Answer

'89 Dynasty 3.0 security system? problem. I appropriately reset the security system (locked and then unlocked the driver's door) after recharging the battery, but now the engine won't fire. It acts like it is in "deep lockdown", even though the anti-theft module remained connected the entire time - before, during and after the recharge. It did this once before when I recharged the battery some time after I had properly disabled the system (removed the connector with the engine running), so I reconnected the module and have driven it the past several weeks with no starting problems. The only fault code I found was for "battery recently disconnected." Any ideas?

You may want to disconnect the battery again and try resetting it again, this may work. As it sounds like you did everything correctly.

2007 Saturn ion 3 door locks fuse location


Power door lock's are controlled by the BCM - body control module . Are you familiar with automotive electronic's ?
Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch--Uses a single signal wire for both lock and unlock switch activations
• Front passenger door lock switch--Uses a single signal wire for both lock and unlock switch activations
• Body control module (BCM)--Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• Body control module PWR 15A fuse--Located in the body control module fuse panel, supplies power for the door lock system

Door Lock and Unlock Operation
The BCM PWR fuse supplies battery positive voltage to the BCM for the door lock system.
The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 1.5K ohm resistor that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.

92 Toyota celcia battery died an now security system won't let it start? What can I do


If it is a factory security system, usually locking/unlocking the doors with the key fob will reset it. On some vehicles, locking/unlocking the drivers door with the key will also reset it

If the security system is activated, usually locking/unlocking the doors with the key fob will reset it. You can also try locking/unlocking the drivers door using the key. Sometimes disconnecting the battery for a minute will also reset the system

Door lock dont always work


What door lock doesn't always work ? One or all of them . This is a complex set up for these door locks ! The switch is an input to the BCM - body control module . There is logic involved in the microprocessor , there are relays built in to the BCM ! Could have a DTC - diagnostic trouble code stored in the BCM ! Could be a bad connection at the BCM or master window switch ! A bad ground !
The power door lock system consists of the following components:
?€¢
Body control module (BCM)


?€¢
DOOR LKS fuse


?€¢
Driver door lock actuator


?€¢
Driver door lock switch


?€¢
GMLAN serial data link


?€¢
Keyless entry transmitter


?€¢
Passenger door lock actuator


?€¢
Passenger door lock switch


?€¢
Remote control door lock receiver (RCDLR)


The DR LCK fuse supplies battery voltage to the body control module (BCM) for the power door lock system. The BCM supplies and monitors a reference voltage to the driver and passenger door lock switches through the door lock switch lock/unlock signal circuit. Each door lock switch receives ground at G300 which is also the ground for the door lock and unlock relays located in the BCM. When a door lock switch is placed in the lock position, the reference voltage is switched to ground and the BCM senses 0.0 volts on the door lock/unlock signal circuit. When a door lock switch is placed in the unlock position, the reference voltage is switched to ground through a 1.5k ohm resistor that is internal to each of the door lock switches and the BCM senses approximately 2.9 volts on the door lock/unlock signal circuit. The BCM interprets what position the activated door lock switch was placed in based on the voltage drop.
The BCM, upon receipt of a lock or unlock switch signal, will switch the appropriate door lock/unlock relay coil control circuit to ground causing the appropriate door lock/unlock relay to energize. With the relay energized, voltage is applied to the door lock actuator control circuit causing the door to either lock, or unlock depending on what command was received from the power door lock switch or remote control door lock receiver (RCDLR). When a power door lock/unlock relay is not energized, the switch contacts are normally grounded through the BCM which provides ground to the appropriate door lock actuator for the lock/unlock function being performed. The power door lock/unlock functions are performed by reversing the flow of voltage through the door lock actuator control circuits. The BCM has three internal drivers for the power door lock system. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked separately from the passenger door. For additional information concerning keyless entry, refer to Keyless Entry System Description and Operation.
This is one you may want to take to dealer or some other ASE certified repair shop ! To do this right you need a Tech 2 scan tool !
Ignition ON, observe the scan tool Door Lock Switch parameter while using the driver and passenger door lock switches. The parameter should change from Idle to Lock and Unlock.
?‡'
If the value does not change, refer to Door Lock Switch Malfunction.

Command the doors to LOCK and UNLOCK with the scan tool, the door lock actuators should LOCK and UNLOCK when changing between the commanded states.
?‡'
If one or more doors do not LOCK or UNLOCK, refer to Door Lock Malfunction.

How do you bridge-out the anti-theft security system....it keeps kicking in and shutting down the van after starting


There is a problem detected within the security system by the security module. Try locking and unlocking the door with the key fob to reset the system. Sometimes locking and unlocking the drivers door using the key will reset the system as well. If still no luck, try the spare key to see if the security system accepts it

2001 maxima alarm not working but panic works


ck for a fuse in the under the hood fuse box that says bsm may be blown.
Also try this.....
To reset the security system remove the negative battery cable for 30 minutes, then reconnect the cable. Next, lock and unlock the doors using the remote. This will reset the alarm system and the engine will start and fobs reset.

Here are some factory notes....FYI

Anti-Theft Systems

PROGRAMMING

NOTE: If a new Smart Entrance Control Module (SECU) is installed, a new identity code must be entered and all remote controllers must be programmed. If identity code cannot be entered, repair multi-remote system. See appropriate MULTI-REMOTE CONTROL SYSTEMS article.

PROGRAMMING > PROGRAMING NEW ID CODE

NOTE: This procedure will erase all previous identity codes and render all previously programmed remote controllers inoperative (until reprogrammed). All remote controllers to be used with system must be programmed at the same time. A maximum of 4 remote controllers can be programmed. Any attempt to program more than 4 controllers will be ignored. If same identity code is entered more than once, entry is ignored even though hazard warning lights will still flash twice.
1. Close and lock all doors. Erase original identity code(s) by inserting and completely removing key from ignition switch more than 6 times within 10 seconds. Hazard warning lights should flash twice. Turn ignition switch to ACC position.
2. Push any button on new remote controller once. Hazard warning lights should flash twice, indicating identity code has been entered. If identity code cannot be entered, repair multi-remote system. See appropriate MULTI-REMOTE CONTROL SYSTEMS article.
3. For each additional remote controller to be programmed, manually release door lock and lock again by using door panel switch and repeat step 2. If no additional remote controllers are to be used, exit programming mode by unlocking and opening driver's door.

Please let me know if you need anything else to get the problem fixed. Happy mew Year!

Security System


I have a 5.2L V8 Jeep Grand Cherokee and i know to reset my security system i actually have to go around to the passenger side door and lock and then unlock it again. Seems fairly odd but that's how i was told it was reset. Give it a go and lemme know!

1990 dodge dynasty 3.3 engine starts fine but a second later dies changed gas filter and fuel pump and regulator still don't stay started.


Same thing happened to my '89 Dynasty. Turns out the security system was engaged and this stops the motor from running; therefore. a thief cannot drive away with the car! The system is set by using the power locks or an autolock fob, but not by locking manually. Disconnecting the battery will also engage the security system. To disengage, close the driver or passenger (front) door and turn the key in the lock.
