3 Turn the ignition off.
Disconnect the TCM harness connectors.
Turn the ignition on.
Measure and note the voltage of both CAN Bus circuit at the TCM harness connector.
NOTE: This code can be caused by an intermittent problem in the wiring
and connectors to the Transmission Control Module. Inspect the Transmis-
sion Control Module harness connector and associated wiring for signs of
poor terminal contact.

following list may help in identifying the intermittent condition.
With the engine running at normal operating temperature, monitor the DRB
parameters related to the DTC while wiggling the wiring harness. Look for param-
eter values to change and/or a DTC to set.
Review the DTC When Monitored and Set Conditions. If possible, try to duplicate the
conditions under which the DTC was set.
Refer to any Technical Service Bulletins (TSB) that may apply.
Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or
partially broken wires.

1NOTE: 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 DRB 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.
Turn the ignition on.
With the DRBIIIt, erase ECM DTCs only.
