When Monitored

WARNING: This page is about a different car, the 2025 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

This diagnostic runs when the PCM receives voltage on the wake up signal from the BCM.
The BCM will send a valid wake up signal to the PCM for any of the following reasons:
- The ignition is turned on.
- A refueling event is requested.
- The Evaporative System diagnostics need to be performed.
