2009 Year Upgrades

Chrysler updated the 2009 model with Hill Start Assist (HSA) to help prevent rollback on graded surfaces, and then incorporated Trailer Sway Control (TSC) that monitored vehicle movement while towing, relative to its intended path.

A new center dome lamp with directional lighting, drop in center console bin, and cargo nets for additional storage were added to the interior although mine did not have said cargo nets.

All 2-door Wranglers came with a 2,000lb maximum towing capacity. The JK 2 door came with a standard 3.6L V6 engine which pushed out 202hp, 237 ft-lbs of torque. Wrangler X vehicles also ran with 16 inch wheels.

Features such as front and rear solid axles, hard or soft top options, removable doors and mirrors, two-speed transfer case, fold down windshield and full size tailgate-mounted spare tire remained standard.

Miscellaneous

Disable seat-belt alarm

1. Turn the ignition switch to the OFF position, and buckle the driver’s seat belt.
2. Turn the ignition key to the ACCESSORY/RUN position (engine does not need to be running), and wait for the Seat Belt Warning Light to turn off.
3. Within 60 seconds of starting the vehicle, unbuckle and then re-buckle the driver’s seat belt at least three times within 10 seconds, ending with the seat belt buckled.
4. Turn the ignition key to the OFF position. A single chime will sound to signify that you have successfully completed the programming.

The Enhanced Warning System (BeltAlert) can be reactivated by repeating this procedure.

The important steps are:

• DO NOT START THE JEEP.
• Get in
• Buckle-up
• Turn the key to ACC on.
• Once the seat belt dummy light goes out, unbuckle and buckle 3 or more times.
• Turn off and remove the key. You should hear a confirmation tone.

Disable security alarm

• It might be possible to disable the security alarm by the removal of a specific fuse. Fuse M13 (see fuse section). This will also likely disable the keyless entry option. Removal of fuse M13 does not disable the alarm.

Security alarm problems

The security alarm goes off for a number of reasons, it is triggered too easily.

Unlocking the doors with the manual door lock plungers or the driver’s door lock cylinder will not disarm the Vehicle Security Alarm.

The Sentry Key Immobilizer System prevents unauthorized vehicle operation by disabling the engine. The system does not need to be armed or activated. Operation is automatic, regardless of whether the vehicle is locked or unlocked. The system uses ignition keys that have an embedded electronic chip (transponder) to prevent unauthorized vehicle operation. Therefore, only keys that are programmed to the vehicle can be used to start and operate the vehicle. The system will shut the engine off in two seconds if someone uses an invalid key to try to start the engine.
