Hi there:
DTC P1684 means Battery Disconnected within last 50 starts
DTC P0700 if the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700

Hope helps.

codes relate to control module, have module checked for faults

SOURCE: check engine light is on 3 codes p0740,p0601,&

P0700 - Transaxle Control System Fault Conditions
The P0700 code is for information only and the next step is to check for transaxle codes in the Transaxle Control Module (TCM). So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

P0740 - Torque Converter Clutch Circuit Malfunction

P0601 - Internal Control Module Memory Check Sum Error
What does that mean?
Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times.

Symptoms
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.

Causes
A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

Possible Solutions
With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.


Good luck!

SOURCE: car wont shift from 2nd gear and speedometer

the PO700 code is a generic transmission code. You would need access to a proper scan tool to check for transmission codes. However if you speedo isnt working, it sounds as though you have a bad output speed sensor. This part runs about 60.00 from the dealer, and is fairly easy to install. No speed signal will put the transmission into limp mode, and keep it stuck in 2nd gear.

1684 is battery disconnected, which you caused when you disconnected it--you can ignore that. You probably have an intermittent misfire. Please follow my troubleshooting steps and let me know if you have questions.

What is the code p1684 and p700


The P1684 code means simply that the battery has been disconnected within the last 50 starts, You can effectively disregard this unless you know that to be false. Then it could be an indication of an impending battery failure.The P0700 code is more troublesome. I collected this information from another source:

What does that mean? Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.
This illuminates the Malfunction Indicator Lamp (MIL) to let the driver know there is a problem. If this code is present and the MIL (Malfunction Indicator Lamp) is illuminated that basically means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.

Symptoms Symptoms of a P0700 DTC may include:
  • Malfunction Indicator Lamp (MIL) illumination
  • The transmission may exhibit drivability problems like slipping, etc.
Causes More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely).
Possible Solutions For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.
If the TCM compatible scan tool will not communicate with the Transmission Control Module then that is a good indication that there may be a fault with the TCM itself.

Hope this helps!

Car does not run ,I check the code ,it is P0700


Because it is not starting, you should replace the Crankshaft sensor (above the oil filter, back of the engine)-it will cause a P0700-I have a 99 SL2, 178,000 miles


DTC) CODE # P0700....Transmission Control System (MIL Request)
Translation: Transmission Control Module (TCM) Malfunction or Failure. P0700 Information Code The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM. This code is for information ONLY. If this code is present, check for transaxle codes. So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can not turn on the check engine light so it has the PCM do it. The dealer probably saw the code P0700 and went to the TCM and pulled out the code stored there telling them the Transmission Solenoid Assembly (TSA) is bad. This is a good example of understanding what the codes actually mean. If the manual you looked at said the TCM is bad and to replace the TCM when you see a P0700, then it is wrong.

I got two odometor codes p1684 and p0700 do you know what it means 2002 chysler town and country


P0 700 is a transmission control malfunction and P1684 is a indication that your battery was disconnected within the last fifty states.However what is puzzling is your PO 700 is a generic code your P1684 is a dedicated Chrysler code your cars computer should only store one or the other not both.

What is the diagnostic codes P 0700 P1684 p0442 p0455 p0456 on a 2001 dodge Caravan with a 3 3"


P0700: EATX Controller DTC present
P1684: Battery was desconnected
P0442: EVAP leak monitor medium (.040). Leak detected.
P0455:
EVAP leak monitor large. Leak detected.
P0456: EVAP leak monitor small (.020). Leak detected.

I suggest check the lines and flow it down to the ldp (leak detection pump) that is just behind the steering gear under the van It has a wire connector and 2 large EVAP hoses. look for any split or crack then follow the lines back to the tank. Even a small crack is a leak.

Hope helped with this. Remember rated this help. Good luck.

How to check the trouble codes on a 2001 chrysler concorde 2 7L


I assume you are asking about the "check engine" diagonstic codes.

You can check the codes yourself by using the key and ignition switch. With the engine off, put the key in the ignition and turn it ON-OFF-ON-OFF-ON -- do not turn to the extreme right "start engine" positon, but to the last click just before the start position.
You will then see a code list read out where the odometer (mileage) usually displays. It will start with dashes in the readout "-------", then each diagnostic code will appear in sequence like P1684, P0700, and then the word "done" after all of the codes have been displayed.

One word of warning -- I have found that sometimes all of the diagnostic codes do not display with this method, so it would be best to also check the codes using an electronic diagnostic code reader. You can do this for free yourself as explained below.

Go to your nearest "national chain -- do it yourself" auto parts store such as Auto Zone or Advance Auto. Ask to borrow the "engine code reader diagnostic tool" -- you will have to give them your driver's license to borrow it. Then, in the parking lot, check the diagnostic codes yourself.

Turn the car key to the "accessory position" -- i.e., not started, but with the accessories on. Power on the diagnostic tool. Plug the attached pin connector into the Chrysler diagnostic socket located just under the dasboard below the ignition switch. Press the "read codes" button on the diagnostic tool -- you will see a diagnostic code and a brief message about what it means. Keep pressing the "next" button until you have read all of the codes.

P.S. Don't forget to get your driver's license back when you return the diagnostic tool!

Check engine light on


P0700 - Transmission Control System Malfunction, this is a transmission or PCM issue and needs further diagnosis with other test gear.

The P1684 code simply means that the battery has been disconneted within the last 50 engine starts.
