P0700-TCM DTC

For a complete wiring diagram Refer to Section 8W

When Monitored:
With the ignition on.
Set Condition:
The ECM recieves a CAN Bus message indicating the presence of a DTC in the TCM.

Diagnostic Test

NOTE: If the ECM detects and stores a DTC, the ECM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed.

NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.

NOTE: This code was set in the ECM by the Transmission Control Module to indicate a transmission fault. Diagnosis of transmission faults should be done using the Transmission Diagnostic Information.

NOTE: When repairs have been completed, the ECM and TCM must have codes cleared.

With the scan tool, erase ECM DTCs only.
