P0888-Relay Output Always Off
WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
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 Powertrain Control Module when the PCM 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.
