P0882-TCM POWER INPUT LOW
For a complete wiring diagramRefer to Section 8W

When Monitored:
When the ignition is turned from
OFFposition toRUNposition and/or the ignition is turned fromSTART
position toRUNposition.
Set Condition:
This DTC is set when there is less than 3.0 volts present at the transmissioncontrol output circuits located in
the Powertrain Control Module (PCM) when the Transmission Control Systemrequest the power up of those
circuits.Note: Due to the integration of the Transmission Control Module and the Powertrain Control
Module, both systems have their own power and ground circuits..
Possible Causes
RELATED TIPM DTCS
(T515) TRANSMISSION CONTROL CIRCUIT SHORT TO GROUND
(T515) TRANSMISSION CONTROL CIRCUIT OPEN
POWERTRAIN CONTROL MODULE
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The Transmission Control Output circuit is used to supply power to the Transmission Solenoid/TRS Assembly and to
the PCM when in normal operating mode. The purpose of the Transmission Output circuit is to allow the Transmis-
sion Control System to turn off the power to the Transmission Solenoid/TRSAssembly in event that the transmission
should need to be placed into “limp-in” mode due to a DTC.
After a PCM reset, (ignition switch turned to the run position, or after cranking the engine) the Transmission Control
System verifies that the Transmission Output circuit is open by checking for voltage on the Transmission Output
circuits before the Transmission Control System request for the circuit to be powered up. The request is sent by a
direct circuit control from the PCM tothe TIPM. If the Transmission Control System detects less that 3.0 volts when
the output is commanded on, the DTC will set.Note: Inadequate Transmission Control Output voltage can also
cause DTCs P0846, P0869, P0871, P0876 or P0988 to set. Repairing the P0882 fault should also eliminate the
related DTCs.
Diagnostic Test
1.CHECK IF THE DTC P0882 IS CURRENT
With the scan tool, Check the STARTS SINCE SET counter for P0882.
NOTE: This counter only applies to the last DTC set.
Is the STARTS SINCE SET counter equal to 0?
Ye s>>
Go To 2
No>>
Go To 5
2.CHECK FOR TIPM RELATED DTCS
With the scan tool, check TIPM DTCs.
Are there any TCM TIPM DTCs present?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom.
No>>
Go To 3

3.CHECK THE (T515) TRANSMISSION CONTROL CIRCUIT FOR A SHORT TO GROUND
Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector and connect Miller tool
#8815.
CAUTION: Do not probe the PCM harness connectors. Probing the
PCM harness connectors will damage the PCM terminals resulting
in poor terminal to pin connection. Install Miller tool #8815 to per-
form diagnosis.
Disconnect the TIPM C1 harness connector.
Measure the resistance between ground and the (T515) Transmission
Control circuit.
Is the resistance below 5.0 ohms?
Ye s>>
