Hello, In my experience with these cars, anytime you get a control module code, the control module is bad.
I hope this helps

My battery light came on while i was driving than a few minutes later everything shut off. The battery was replaced in january and alternator was replaced in october.. what could be the problem?


For the alternator to work B+ voltage must be applied to the heavier gage wire on the back of the alternator ,plus the alternator is computer controlled , by the PCM !
Charging System Indicators
BATTERY The IPC illuminates the battery indicator when the following occurs:
?€¢
The PCM detects that the generator output is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the PCM requesting illumination.


?€¢
The IPC determines that the system voltage is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the body control module (BCM) indicating the system voltage.


?€¢
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.


?€¢
The ignition is on, with the engine off.
BATTERY NOT CHARGING The IPC illuminates the battery not charging indicator in the driver information center when the following occurs:
?€¢
The PCM detects that the generator output is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the PCM requesting illumination.


?€¢
The IPC determines that the system voltage is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the body control module (BCM) indicating the system voltage.


Your best is to have a qualified repair shop check it out ! Could have DTC'S - diagnostic trouble codes stored !
DTC P0562
The powertrain control module (PCM) continuously monitors that the system voltage stays within the proper range. If the PCM detects an excessively high system voltage, DTC P0563 will set. A high voltage condition may cause a stalling condition or other drive ability concerns.
DTC P0621
The powertrain control module (PCM) uses the generator turn on signal circuit to control the generator. A high side driver within the PCM allows the PCM to turn the generator ON and OFF. When Generator operation is desired, the PCM sends a 5 volt signal to the voltage regulator via the generator turn on signal circuit. This causes the voltage regulator to begin controlling the generator field circuit. Once the Generator is enabled by the PCM, the voltage regulator controls generator output independently of the PCM. Under certain operating conditions, the PCM can turn Off the generator by turning Off the 5 volt signal on the generator turn on signal circuit. The PCM has fault detection circuitry which monitors the state of the generator turn on signal circuit. If the fault detection circuit senses a voltage other than what is expected, this DTC will set. The voltage regulator also contains fault detection circuitry. If the regulator detects a problem, the regulator will ground the generator turn on signal circuit, pulling the voltage low. This also causes the PCM to set the DTC.
DTC P0622
Checking for codes an voltage drop testing the connections an using a scan tool to check data parameters is the only way to solve your problem . Which means taking to a qualified repair shop !

Airbag light came on my 05 f 150 code is 33 how do I fix it


Check with dealer might be a recall for defective srs.

Airbag light stays on


Cluster warning lights

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

My 2003 ford expo has a constant airbag light lit after starting the veh. I have a new sensor, can't figure out were 2put it.. Please help.


first, you need to read the Lamp Fault Code, LFC from the flashing light. Here's how:

Lamp Fault Codes
When the restraints control module (RCM) detects a system fault, it will cause the air bag indicator to flash a coded sequence: a lamp fault code (LFC). The code is two digits. The first digit is flashed with a 0.5 second interval between pulses. There is a 2 second pause before the second digit is flashed, which also has a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indictor will remain lit for the remainder of the key-on cycle. If there are multiple LFCs, each LFC will flash in order of priority.
-------------------------------------------------------
The fault could be in the air bag circuits, the canopy circuits, the pretensioner circuit on the seat belts, etc.
Report back with code.

here's some of system.

SECTION 501-20B: Supplemental Restraint System 2003 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants in addition to that provided by the three-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.
This vehicle line contains dual stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles can also be equipped with optional safety canopies that deploy from the A-pillar to the C-pillar upon a side impact or if a rollover condition is detected. If equipped with safety canopies, a unique restraints control module (RCM) is used.
See the following illustration for deployable component location.
