This could be any one of several issues with wiring, internal transmission problems, or the controller itself. It should be possible for a person with a good scan tool to read the transmission codes which may help identify the problem. Most parts store free scans will not read these codes. You need a transmission shop or the dealer.

SOURCE: Malfunction Indicator Lamp (MIL)

I had the samething happen to my Jetta. I took it to the dealer and nothing was wrong.
I would think it's safe to drive until Monday when the VW shop opens.

SOURCE: Malfunction indicator lamp

The Malfunction Indicator Lamp or MIL (Also called the check engine light or service engine soon light) comes on when the on board computer detects an issue with the operation of the engine or transmission.

The best thing to do is to take the vehicle to an auto parts store like Autozone and have them hook up their scan tool to the vehicle and read the code. They can read it, tell you what it is and also tell you what the code means.

If it is pointing to a faulty component or sensor and you replace or repair the component the the light will go off on its own after the computer sees that the malfunction is no longer present.

You can have the code cleared, but if whatever caused the light to come on in the first place is not addressed then it will just come back on eventually.

SOURCE: malfunction indicator lamp in my toyota corolla is on how i fix?

The check engine light also called the malfunction indicator comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

I have a 2009 Chevy Avalanche LS and I got the P0700 code, how easy is this to fix? where is the TCM located? If this is a dealer service how much?


DTC P0700: Transmission Control Module (TCM) Requested MIL Illumination
The transmission control module (TCM) uses the (GMLAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This happens when the TCM has determined that a failure affecting emissions has occurred in transmission control system. When the ECM receives the message from the TCM, DTC P0700 will set.
DTC P0700 can not be cleared from the ECM until the related TCM codes have been cleared.
This is something best left to a qualified repair shop , doesn't need to be the dealer ! AMMCO could fix it . This code is telling that other codes are stored in the transmission control module . Need a professional type or factory scan tool to check these . As to how much it will cost , no telling without knowing the codes in the TCM !

You need to have TCM checked for codes .

P0700 Transmission Control System Malfunction OBD-II Trouble Code Technical Description Article by Dale Toalston ASE Certified Technician Transmission Control System TCS Malfunction 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.
