DTC Descriptor

DTC P0700

- Transmission Control Module (TCM) Requested MIL Illumination

Circuit/System Description

The diagnostic trouble code (DTC) indicates that an emission related transmission DTC set in the transmission control module (TCM). The engine

control module (ECM) receives the TCM 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. The DTC information for the ECM will only display DTC

P0700, but the Freeze Frame/Failure Records data will display the transmission DTC that set.

Conditions for Running the DTC

* The ignition is ON or the engine is operating.

* DTC P0700 runs continuously.

Conditions for Setting the DTC

The ECM receives a serial data message from the TCM requesting the ECM to turn ON the MIL lamp.

Action Taken When the DTC Sets

DTC P0700 is a Type A DTC.

Conditions for Clearing the MIL/DTC

DTC P0700 is a Type A DTC.

Diagnostic Aids

Communication codes, U-codes, as well as powertrain codes, P-codes, set in the TCM can cause the TCM to request DTC P0700 to be set in the

ECM.
