Re: 2003 L300 error codes P0700 & P0727
P0700 is a generic TCM error. See below
The Engine Control Module (ECM) , Transmission Control Module (TCM) , and the Body Control Module (BCM) communicate with each other over the Controller Area Network (CAN) bus circuits 2500 and 2501. The CAN BUS is a communications protocol that is used by the TCM to communicate vital engine control inputs from a stand-alone engine controller. The diagnostic checks the information received in CAN to determine whether a pass or fail code. Before checking the information, the TCM makes sure the CAN messages are being received by checking the BUS failure timer.
DTC P0727 will set if:
CAN bus signal for the engine speed circuit is not responding for 2 seconds .
System voltage is between 8 and 18 volts .
Engine speed is greater than 500 rpm for 5 seconds and not at fuel cutoff.
This code does not indicate a problem with the TCM. It does indicate the ECM is not sending engine speed to the TCM.
Determine the problem or look for trouble code(s) in the ECM.
