1990-1994 Lexus LS400 How to Check Air Conditioning Diagnostic

1) First perform an indicator check to see if all the lights are working properly. Press and hold the AUTO & REC buttons and then start the car. Release the buttons after the car has started. All the lights should light up and go off 4 times in a row at one second intervals. You should also hear a beep as the indicators light up. After the indicators blink 4 times you’re in A/C diagnostic mode. 2) Read the code displayed on the LCD. Here you see a code 21; this can happen if you’re not in light because it refers to the solar sensor. 3) Here’s what normal will look like, code 00. When the codes are displayed they blink and beep. Here are all the codes that can be displayed……… Code – Meaning 00 – Normal 11 – Open or short in room temperature sensor circuit. 12 – Open or short in ambient temperature sensor circuit. 13 – Open or short in evaporator temperature sensor circuit. 14 – Open or short in water temperature sensor circuit. 21* – Open or short in solar sensor circuit. 22* – Compressor motor locked. And/or, open or short in compressor lock sensor circuit. 31 – Open or short in air mix damper position sensor circuit. 32 – Open or short in air inlet damper position sensor circuit. 33 – Open in air mix damper position sensor circuit. Or, open or short in air mix servomotor circuit. Or, air mix servomotor locked. 34 – Open in air inlet damper position sensor circuit. Or, open or short in air inlet sensor servomotor circuit. Or, air inlet servomotor locked. * – These are detected only when they are the current troubles. Other codes detect both current trouble (beep) and past trouble (no beep). A/C indicator light blinks – This means your A/C compressor is locked. It’s happened to me before and I needed a new (rebuilt) compressor installed. 4) Once you’ve read any codes you can proceed to performing an actuator check by pressing the REC button. This will start a check of different combinations for the system starting with code 20 and moving up to 29. To cancel this or the previous diagnostic modes simply press the OFF button.

2006 Ford F-SUPER DUTY Class A Motorhome Chassis INCOMPLETE VEHICLE MANUAL

Certain exhaust system components, including exhaust heat shielding systems, have been installed on some vehicles in our assembly plants in an effort to provide protection against engine compartment and exhaust system temperatures. Subsequent aftermarket installers/manufacturers are responsible for providing thermal protection (e.g. underbody heat shields) for any structure and/or equipment added to the vehicle and should not remove any components or exhaust heat shielding installed on the vehicle by Ford Motor Company. All exposed interior sheet metal of closed structures (e.g. fl oor pan of cab and/or secondary structure, tool boxes, etc.) should be covered with an insulating material capable of protecting vehicle occupants and contents from temperatures potentially up to 700°F. OZONE DEPLETING SUBSTANCE (ODS) OZONE DEPLETING SUBSTANCE (ODS) The Clean Air Act of 1990, Section 611 requires any product (i.e., completed vehicle) containing or manufactured with any Class I Ozone Depleting Substance on, or after May 15,1993 must be identifi ed with a “clearly and conspicuously attached label.” Ford Motor Company has eliminated Class I ODS from its manufacturing processes. All 2006 Ford Truck incomplete vehicles will not have Class I ODS content. Manufacturers, including subsequent stage manufacturers, are required to label their products if the product, including any component (whether manufactured by that manufacturer or not), contains a Class I ODS or if the manufacturer used a Class I ODS in the manufacturing of the product. In the case where Ford Motor Company provides a label saying the incomplete vehicle contains a Class I ODS that information must be placed on the product warning label. (See EPA regulation on wording, placement, size, and combining labels.) In Canada consult the appropriate Provincial or Territorial Ministry of Environment. EMISSION CONTROL INFORMATION LABEL To meet United States Environmental Protection Agency regulations, the Important Vehicle Information (tune-up and fuel tank capacity) labels must be affi xed in a location that is readily visible after installation and in such a manner that it cannot be removed without destroying or defacing the label. The label shall not be affi xed to any equipment that is easily detached from the vehicle. When emission control labels are supplied but not attached to the vehicle (i.e., tune-up label or fuel tank label), they must be permanently mounted in a readily visible location to meet the preceding requirements. In addition, whether the label is already affi xed or to be affi xed, no components shall be installed which visibly obscure the label in any way that fails to satisfy the visibility requirements described in the California Emission Control Label Specifications. For Canadian requirements consult Section 1100 8 (1) (d) (i), (ii), & (iii). CALIFORNIA FUEL VAPOR RECOVERY California regulations require that the vehicle fuel systems be designed to accommodate a vapor recovery fueling nozzle including unobstructed access to the fi ll pipe. Fuel fi ller pipes installed per the Figure B on page 15 will comply with the “Specifi cations For Fill Pipes and Openings of Motor Vehicle Fuel Tanks” referenced in Title 13 California Administrative Code provided no part of the aftermarket body, as installed, intrudes within a 254mm [10 in] radius cylinder which has its axis parallel to the ground at point “Z” and extends outward from the Ford Motor Company supplied fuel pipe housing component. The fuel pipe housing component is shown on the referenced fi gures and is attached to the aftermarket body via 4.76 mm [.188 in.] diameter rivets. Fuel fi ller pipes installed using the alternative bracket shown in Figure B, will comply with the above California vapor recovery regulations provided the aftermarket body does not interfere with the access zone as defi ned by the California Air Resources Board, and the areas adjacent to this opening cannot foreseeably damage the nozzle bellows or face plate of nozzles during insertion, latching, disposing or removal
