Hi KIM.
The letters TCM Are Traction Control Module. Most probably you might have a fault into driving and have any unsteadiness or well traction. It is logical to use a scanner to locate exactly the traction fault which is already got into the module and memorized . Happens to me on a Mini Cooper S Works 2006 where I spotted the fault on the back axle where the sensor was and due to mad the traction was seized. I cleaned the sensor washed and use a bit of silicon spray after washed with a good contact cleaner.

Check engine light indicates p700 code


Diagnostic Test Code (DTC) P0700 is an informational code that is stored in the Engine Control Module (ECM) That informs the diagnostic technician that there are codes present in the Transmission Control Module (TCM) and that the TCM has requested the Malfunction Indicator Lamp (MIL) (AKA - Check Engine Light) to be turned on. This is because the MIL is controlled by the ECM and cannot be turned on directly by the TCM. So, the TCM requests the ECM to turn the light on. To find out the nature of the failure that caused the P0700, one must scan the TCM to retrieve the fault codes stored there. Please note that MOST generic OBD code readers cannot access the TCM - this is the reason for the P0700 code to set in the ECM (to alert somebody with a generic code reader that further diagnosis is needed for the TCM).

What part do i need to repalce


Hi Cornejo:
The DTC (Diagnostic Trouble Code) P0700 code is not the actual code that is of concern. The P0700 code is stored in the engine computer.

This code means that there is a code stored in the Transmission computer. The trans computer sends a message to the engine computer that there is a trans code stored. This lets the engine computer turn on the "check engine" light.

You need to have the transmission computer scaned for codes to find out whats going on. Most code readers do not read trans codes, you need to have a scan tool that is able to do this.
This could mean almost any thing. Most trans codes are eletrical related with the allison transmission.
Here is the diagnosis chart for the P0700. Again, this code only means a trans code is set in the TCM, not a actual failure code.
--------------------------------------------------------------------------------------------------------
DTC P0700
Circuit Description
This diagnostic trouble code (DTC) indicates that a related transmission DTC set in the transmission control module (TCM). The engine control module (ECM) receives the TCM DTC information over the serial data circuit. The ECM turns ON the malfunction indicator lamp (MIL) when the TCM sends a message over the serial data circuit requesting MIL illumination.

2_15_2012_1_58_02_pm.gif

Conditions for Clearing the DTC graphic
The control modul turns OFF the MIL after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A scan tool can clear the code from TCM history. The TCM automatically clears the DTC from TCM history if the vehicle completes 40 warm-up cycles without failure.

1. Verify power and ground supplies to the TCM when the vehicle is cold.

2. If OK, depending on ambient temperature. If ambient temperature is high and the problem will not show, remove the TCM and place it in a freezer for a couple of hours.
3. If the ambient temperature is low remove the TCM to a warm area for a couple of hours.
4. After sufficiently cold or warm, install the TCM and drive the vehicle immediately.
5. If the ambient temperature is low and the transmission now shifts or the ambient temperature is high and the transmission will not shift replace the TCM.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

I bought a 1998 mitsubishi eclipse and the check engine light came on we hooked up the machine to diagnos it and we got 2 codes po700 and p1784 . we are wondering what the codes mean and how to fix the...


DTC 1784: LOW-REVERSE PRESSURE SWITCH
1.Remove transaxle relay from connector. Turn ignition on. Install scan tool and observe low-reverse pressure switch condition. Apply battery voltage to transaxle relay connector terminal No. 8. If low-reverse pressure switch stays off, go to next step. If low-reverse pressure switch turns on, go to step 4 .

2.Raise vehicle enough to allow drive wheels to spin freely. Test low-reverse clutch hydraulic pressure. See HYDRAULIC PRESSURE TESTS under TESTING. If low-reverse clutch pressure test is not within specification, internal transaxle failure exists. If low-reverse clutch pressure test is within specification, observe scan tool.

3.If low-reverse pressure switch turns on, trouble code is intermittent. Check wire harnesses and connectors for damage or poor connection. If low-reverse pressure switch does not turn on, replace solenoid and pressure switch assembly. Recheck trouble codes. If trouble code resets, replace TCM.

4.Check and repair wiring harness between transaxle relay connector and solenoid and pressure switch assembly connector. If wiring harness is okay, check wire between TCM connector terminal No. 10 and solenoid and pressure switch assembly.

5.If wire between TCM connector terminal No. 10 and solenoid and pressure switch assembly is okay, check TCM and solenoid and pressure switch assembly connectors. Repair connectors as necessary. If connectors are okay, recheck trouble codes. If trouble code resets, replace solenoid and pressure switch assembly. Recheck trouble codes. If trouble code resets, replace TCM.

P0700-The Transmission Control Module (TCM) monitors the malfunction of sensors and actuators relating to transmission control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transmission controls.

I would try disconnecting he battery and letting it sit for 5 minutes, then hook it back up to see if they return-the 700 code is probably related to the 1784 code, that seems to be your main issue.

I have a 2004 Chrysler 300m with a 3.5l engine and getting a 0871 and 0700 code.


Please don't forget to rate!


Trouble Code: P0871 (3.5L V6 VIN G Auto)
A/T O/D Pressure Switch Circuit Malfunction


Trouble Code Conditions:
Engine started; vehicle driven in a forward gear, and the PCM detected that the O/D Pressure Switch circuit indicated open or closed at the wrong time.

Possible Causes:

  • Related DTCs may be present
  • O/D pressure is incorrect, or internal transmission faults exist
  • O/D pressure switch circuit is open, shorted to ground or power
  • O/D pressure switch is damaged or it has failed
  • TCM relay power circuit to O/D switch is open (loss of B+)
  • Intermittent wiring or connector problems exist
  • PCM or TCM has failed


Trouble Code: P0700 (3.5L V6 VIN G Auto)
Automatic Transmission Control System Malfunction


Trouble Code Conditions:
Ignition on or engine started. The PCM received a message over the CCD Bus from the Transmission Control Module (TCM) that it had detected a problem and set a trouble code in memory.

Possible Causes:

  • The presence of this code means the TCM detected a problem
  • TCM related Sensor has solenoid is damaged or has failed
  • This code is for information only - check for other TCM codes
  • TCM or PCM has failed

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.
