Jeep Wrangler: Forward Collision Warning (FCW) With Mitigation — If Equipped / Service FCW Warning
If the system turns off, and the instrument
cluster displays:
- ACC/FCW Unavailable Service Required
- Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under
normal conditions, have the system checked by
an authorized dealer.
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that
limits FCW functionality...
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold placard
pressure.
NOTE:
The alert warning on the cluster will stay on until
the tire is inflated to the placard pressure...

In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions
will take place to extend the driving time and
distance of the vehicle...
