2002/03 X type 3.0 L V6 back up warning system

Do you still hear warning chimes ?
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings. The BCM receives audible warning requests via the class 2 serial data line or the controller area network (CAN) data line. If the BCM receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
Do you have base or uplevel system ? Who put in the NEW delco radio ? I suggest you watch this video . GMC Acadia Diagnose Radio Volume Stuck On HIGH Part II A GM radio is the same for chevy , gmc , buick etc... an could need programming , just watch eric .He had radio fixed same problem .Some times you can't get away from going to the dealer.

The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the speaker. The radio receives audible warning requests via the serial data circuit. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
?€¢
Fast rate chime (200 pulses per minute)

?€¢
Medium rate chime (150 pulses per minute)

?€¢
Slow rate chime (50 pulses per minute)

?€¢


Single chime

It comes through the radio an left front speaker .
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the left front speaker. The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The Multifunction Alarm generates the audible warnings on vehicles with RPO UL5 -- Radio Delete Option. The following lists the audible warning priority and the pulse rate:
The radio activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a class 2 message to the radio indicating the chime frequency of a medium rate and at a continuous duration. The door ajar warning sounds and the door ajar indicator illuminates when the following occurs:

1. The body control module (BCM) determines that the driver's door is open and the signal circuit low. The IPC receives a message via class 2 from the BCM requesting illumination of the door ajar indicator.
2. The vehicle is not in park. The BCM receives a class 2 message from the PCM indicating the gear position.

Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate and share data with each other:
?€¢
Auxiliary Power Drop Connector

?€¢
Body Control Module (BCM)

?€¢
Driver Information Center (DIC)

?€¢
Electronic Brake Control Module (EBCM)

?€¢
Instrument Panel Cluster (IPC)

?€¢
Powertrain Control Module (PCM)

?€¢
Radio

?€¢
Remote Playback Device-CD Player (if equipped with UQ3)

?€¢
Inflatable Restraint Sensing and Diagnostic Module (SDM)

?€¢
Vehicle Interface Unit (VIU) (if equipped)

The class 2 serial data link allows a scan tool to communicate with the above modules for diagnostic and testing purposes.

When it comes up the screen, the sensor part is working. It could be the buzzer is defect, or just the wiring or a connector to the busses or speaker is lose. Start checking the whole chain.

I think you need a deeper code read- only the dealer can get the diagnostic codes to find the specific sensors that might be broken. Should do it for free or a few dollars

check your owners manual under oil change or some variation of that. other wise. try this. turn your key to the on position but do not start the car. next fully press the gas petal 3 time within 10 secs. you should get some type audible signal that the oil change light has been reset.

NOTE: If a double audible warning sounds during the programming procedure a system malfunction has occurred. Repeat programming procedure.
Obtain all keys fitted with remote control. Open driver's door. Operate headlamp high/low beam switch to flash high beam position and hold. Insert key into ignition switch, turn to ACC position. Ensure system LED flashes once and an audible warning sounds. Operate headlamp high/low beam switch to flash high beam position 5 times. Ensure system LED flashes once and an audible warning sounds. Programming mode activated: Press and release lock or unlock button on first key. Ensure system LED flashes once and an audible warning sounds to indicate correct programming. Repeat programming procedure for remaining keys. Switch ignition OFF and remove key. Close driver's door. Check operation of keys. Keys can also be programmed using diagnostic equipment.

From the F-150 Forums, since I just bought one and this worked!

This is straight from my 2009 f150 owners guide

Preperation
1. the parking brake is set
2. truck in park
3. ignition switch is in off position
4. both seat belts are unbuckled

Disable Belt-Minder
1. turn the ignition switch to the on position, DO NOT START THE ENGINE.
2. wait until the safety belt warning light turns off. (approximately 1 minute).
* step 3 must be completed within 50 secs after the safety belt warning light turns off.
3. buckle then unbuckle the seat belt nine times, ending in the seat belt unbuckled.
* after step 3 the restraint warning light, (airbag light) will turn on for three (3) seconds.
4. within approximately seven (7) seconds of the light turning off, buckle then unbuckle the safety belt.
* the restraint system warning light will flash four, (4) times per second for 3 seconds for confirmation

you can do this for the passenger side also!!!


*NOTE
in step 3. after three times buckling and unbuckling the restraint warning light lit up in my truck. SO I WENT TO THE NEXT STEP, (STEP 4). waited 3 seconds and i buckled and unbuckled.

in the buckle /unbuckle procedure do it some what slowly and watch for the light. it may not take 9 times.
