1997 honda accord tranmission problem code p0700 drive 4 flashes


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.

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.

Hope this helps!

Hi John:

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.

I have a chrysler 300m, it drives good, but every time i come to a stop, it jerks. i put it on a computer, code 0700 comes on (tcm). .where is it located? can i fixd it on my own?


Fault P0700 just means the PCM (Powertrain control module) has had a command from the TCM (Transmission control module) to trun on the Check engine light to alert you that a fault has occurred in the Transmission, the real problem code is stored in the TCM not the PCM, you must have the dealer test the TCM for the fault code to find out what is casing the TCM fault

18034 code,i think is a bad conection, in the TCM,but where is it.my car is a audi a4 2005


Trouble code identification:
VAG type 5-digit fault code 18034 = EOBD type P1626 fault code:
Fault location = CAN data bus, TCM - no signal
Probable cause = TCM trouble code(s) stored, TCM incorrectly coded, wiring, matching resistor in ECM.
