2003 ford f150 supercrew lariat. Odometer is all dashes. All lights headlight tail lights park lights are all on even with switch off and keys out. Horn won't blow. Engine will turn over but not crank.


Engine will turn over but not crank.???? Engine cranks but won't start an run .
Odometer
The instrument cluster receives odometer rolling count status from the PCM and stores the mileage in non-volatile memory (NVM). When the instrument cluster fails to receive the odometer rolling count status for more than two seconds, the odometer display will show dashes.

B2143 Odometer NVM Memory Failure Instrument Cluster INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. CLEAR the DTCs. REPEAT the self-test.
Taking the vehicle an having it checked for DTC'S - diagnostic trouble codes would be a good idea ! Not to autozone or advance etc... Need a professional or factory scanner to check for these codes .

How do i get the on bored compressor to work on my 2003 Hummer H2


There is a lot involved in is air ride suspension system ! A 60a Fuse in the under hood fuse block Marked VSES / ECAS .This is the power for the compressor . There is a air suspension control module , Ride height switch , Fuse in the I / P fuse block 4 WD 15a supply's B+ to ride height switch . There is a electronically controlled air suspension relay that the control module energizes to send power to turn on the compressor.

This system can an will store DTC"S in the control module !
Diagnostic Starting Point - Air Suspension
Begin the system diagnosis with the Diagnostic System Check - Air Suspension . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control module(s) which command the system.


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status.

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
If you don't know about this stuff , I strongly suggest you take it to a repair shop ! Do you know about electrical circuits , relay's fuse's ? Do you know how to use a volt meter, read a wiring diagram. The first thing to do would be hook up a scan tool ,not a code reader. This system can set several DTC'S -diagnostic trouble codes.

You need to be able to test for B+ at different points in the wiring !

The reduce engine power message keeps coming on, giving limited power when driving does anyone know what the proble could be with my 2007 hummer H2 SUT.


The Powertrain Control Module (PCM) is shutting down your throttle body control for some reason and limiting how much throttle you can apply. The only way to find out why it is doing this is to scan the PCM for Diagnostic Test Codes (DTCs) and diagnose any existing codes accordingly. It is very likely to be caused by a fault in your throttle position sensor or accelerator pedal position sensor circuits.

There is a Technical Service Bulletin (TSB) for your vehicle which covers a known problem with reduced engine power and sets DTC P2138. The known problem is that the Accelerator Pedal Position (APP) sensor circuits are being infiltrated by water intrusion into a connector and causing erratic voltage readings at the PCM. It is TSB reference # 07-06-04-019D

Hi, how do i put off ''maintenance required'' sign on my toyota camry 2007 car dashboard?Just did the servicing, the sign is still there?


with the key in the off position press and hold the odometer trip reset button on the dash. Turn the key to the run position while continueing to hold the reset button, do not start the car. The odemeter display should change to all dashes and then the dashes will start to go off one at a time. Once they are all out the odometer will display all zeros and then return to its normal display. Sometimes the trip A odometer needs to be displayed before starting and sometimes the trip B.

Your owners manual will give you some more insight if needed.

Can I get the codes by using my on/off ignition switch or do I have to use a reader


To query and OBD-I-era computer for these codes, put the key in the ignition and turn the key to run (not start), then off, then run, then off, then run (that's 3 runs and 2 offs). Leave the key in the run position.

The check engine light will turn on for a few seconds, then turn off, then (sometimes after 20-30 seconds) start flashing. The flashes are counting out 2-digit trouble codes. Fast flashes count up each digit, with a longer pause between digits. On TJ's with a digital odometer, the code numbers are printed on the odometer in addition to flashing the check engine light. 55 indicates the end of all codes. Once you've got your code list, consult the table below to see what they mean.

OBD-II information is more complex, so the codes for 1998 and newer Jeeps can't be displayed by flashing the check engine light. However, those vehicles which have digital odometers will display the codes on the odometer. I've verified this personally on a 1999 WJ. For those vehicles without digital odometers, or for anybody who wants an English description rather than just a numeric code, an OBD-II code scanner ($100-300) can be plugged in under the dash. OBD-II codes can be looked up online here.


These codes were taken from the '95 XJ/YJ factory service manual.

I hope help you woth this. Good luck (rated this).
