F22 did self test and still reads f22

You have a shift interlock problem . What kind of vehicle ? a mercury what ?
Shift Interlock System
The shift interlock system prevents shifting from PARK unless the brake pedal is depressed. The shift interlock system consists of a shift lock actuator mounted on the selector lever. If the ignition switch is in the RUN position, the shift lock actuator is disabled when the brake pedal is depressed.
If the selector lever will not move out of PARK with the key in the ON position and the brake pedal depressed, it will need to be unlocked manually.
Do the brake lights work ?
Visually inspect for obvious signs of mechanical and electrical damage; refer to the following chart:

Visual Inspection Chart Mechanical Electrical

• Damaged shift lock actuator
• Damaged transmission control (TC) switch
• Damaged shift interlock switch

• Failed fuse(s):
  • F20 (10A)
  • F22 (15A)
• Damaged wiring harness
• Loose or corroded connections
• Damaged shift interlock switch

Symptom Chart Condition Possible Sources Action

• Shift interlock system does not release/lock correctly

• Circuitry
• Fuse(s):
  • F20 (10A)
  • F22 (15A)
• Brake pedal position (BPP) switch
• Brake shift interlock actuator
• Brake shift interlock actuator module

• Go To Pinpoint Test A .

PINPOINT TEST A: SHIFT INTERLOCK SYSTEM DOES NOT RELEASE/LOCK CORRECTLY Test Step Result / Action to Take A1 TEST THE BRAKE LIGHTS

• Apply brake pedal and view brake lights.
• Do brake lights illuminate?

Yes
GO to A7 .

No
GO to A2 . A2 TEST FUSE F22 (15A)

• Key in OFF position.
• Check fuse: Smart Junction Box (SJB) Fuse F22 (15A).
• Is the resistance less than 5 ohms?

Yes
GO to A4 .

No
GO to A3 . A3 TEST THE CIRCUIT FOR A SHORT TO GROUND

• Key in OFF position.
• Disconnect: Brake Pedal Position (BPP) Switch.
• Measure the resistance between pin 1 and ground.
  
• Is the resistance greater than 10,000 ohms?

Yes
GO to A4 .

No
REPAIR circuit for short to ground. TEST the system for normal operation
Do

Open exhaust thermistor at room temp should read 11.5-13.5 k-ohms

1) F22 mean DOOR LOCK ERROR , this problem can be a) switch for open or defective b) loose wires or broken wires, test by continuity VOM .
2) adjust the Door vs switch very well for propely closed, and test the closed switch.
3) see if the color are missing and put in the WRON terminal.

God bless you

These are results of two sections of Dell Diagnostics tests which can be run by pressing F10 at startup.

You would have to watch them run to see what has failed during the test.

From Targeted Read Test WHD-20-2RQ failed, could be failure to read RAM (memory), CD/DVD Drive, or Hard Drive.

Something failing within Smart Short Self Test WHD16-FTD could literally be anything within the computer, without seeing what has actually failed during the test.

Just read your machine user manual.you will find detail info.about all the button.
NOTE: Do not skip ''self test". because during self test mode machine check it self & make sure that it is working properly.

It seems there is a possibility of a problem with the printer itself, or perhaps the cartridge. You should first self-test the printer. Since we are unsure where the problem exists, we must do eliminative troubleshooting to rule out parts of the printing system. The self-test allows us to rule out software and the cable by testing the hardware by itself. Please note that this is not a "fix," but rather a diagnostic test to determine if your hardware is at fault.

Please begin by disconnecting the power supply from the wall (not the back of the printer) for at least "30 seconds." Then plug the printer back in.

Next, try this printer self-test by following the steps given below:

1. Make sure the printer is in “Copy Mode.”
2. Press the “Menu” button once.
3. The screen will display “Copy Menu: Copies”.
4. Press the left arrow button once. The screen will display “Copy Menu: Tools”.
5. Press the check button once. The screen with read “Tools: Maintenance”.
6. Press the check button once. The screen with read “Maintenance: Ink Levels”.
7. Press the right arrow button until the screen reads “Maintenance: Print Test Page”.
8. Press the check button once. This will start the Self-Test. Once the page has printed, the printer will stop. The test is not continuous.

The self-test should at least print out a set of either a solid black or solid color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, please try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with only a color cartridge installed (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed). If you find that either cartridge causes the self-test to fail, please let us know.

If the self-test prints, but has lines or smudges or other print quality issues, please let us know. This includes any print quality issues - we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.

If the self-test prints your test bar(s) clearly, the printer hardware is not at fault.

"F22" is a door latch error. The following link explains:

Read through all the steps listed and let me know if you still require assistance. I hope this helps you.

Yes; your hard drive needs to be replaced as a read error indicates a physical problem with the drive reading from a certain or, more likely, many portions of the drive.

Thanks and please take a moment to give this a thumbs up rating, solving your problem.

I disassembling my canon eos kiss body my self.

I used some pictures given by Google search. Did u try that??
