Code P0885 Chrysler Description
Immediately after a controller reset (ignition key turned to the run position or after cranking engine), the PCM verifies that the relay contacts are open by checking for no voltage at the switched battery terminals. After this is verified, the voltage at the pressure switches is checked. There should be no voltage on the pressure switches at this time. The PCM will then activate the relay.

- Faulty Transmission Control Module (TCM) Power Relay
- Transmission Control Module Power Relay harness is open or shorted
- Transmission Control Module Power Relay circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
