P0888
P0882-TCM POWER INPUT LOWP0888-RELAY OUTPUT ALWAYS OFF
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P0882-TCM POWER INPUT LOW.
When Monitored and Set Condition:
P0882-TCM POWER INPUT LOW
When Monitored: Continuously
Set Condition: This DTC is set when less than 3 volts are present at the Transmission Control Relay output circuits at the Transmission Control Module (TCM) when the TCM is energizing the relay. 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.
