TEST ACTION APPLICABILITY
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 DTC indicates a communication problem between the TCM and
the ECM.
Turn the ignition on.
With the DRBIIIt, erase ECM DTCs.
Perform several engine run cycles, turning the ignition off for at least 20 seconds
between each engine run cycle.
With the DRBIIIt, read the ECM DTCs.

2 Turn the ignition on.
With the DRBIIIt, attempt to read TCM DTCs.
NOTE: If the DRB is unable to communicate with the TCM, refer to the
symptom list for problem related to TCM Communication.

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.
Is the voltage between 2.2 volts and 2.8 volts for each measurement?All
Ye s!Test Complete.
Perform ROAD TEST VERIFICATION - VER-2.
No!Repair the CAN Bus circuit(s) for an open.

4WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
NOTE: The conditions that set the DTC are not present at this time. The
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.
Visually inspect the related wiring harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
Were any of the above conditions present?All
Ye s!Repair as necessary.
