Symptom:
P0884-POWER UP AT SPEED
When Monitored and Set Condition:
P0884-POWER UP AT SPEED
When Monitored: When the Transmission Control Module initially powers up. Note: the
Transmission Control Module is integrated with Powertrain Control Module. The Trans-
mission Control Module has separate powers and grounds specifically to its portion of the
PCM.
Set Condition: This DTC will set if the TCM powers up and senses the vehicle in a valid
forward gear (no PRNDL DTCs) with a output speed above 800 RPM (approximately
32Km/h or 20 MPH).
P0884 POWER UP AT SPEED
TEST
1 This DTC is set when the PCM is initialized while the vehicle is moving down the
road in a valid forward gear. This is usually a momentarily loss of power to the
Transmission portion of the PCM.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
NOTE: Due to the integration of the Powertrain and Transmission Control
Modules, the transmission part of the PCM has its own specific power and
ground circuits.
Check all of the Fused B+, Fused Ignition Switch Output, and Ground circuits
related to the PCM for an intermittent open or short to ground.
Perform a wiggle test on all wiring and connectors pertaining to the PCM while
looking for shorts and open circuits.
With the DRBIII , check the EATX EVENT DATA to help identify the conditions in
which the DTC was set.
If there are no possible causes remaining, view repair.
