1998 Chevrolet Chevy K Pickup DTC P1626 Theft Deterrent Fuel Enable Signal Not Received Repair Manual

An intermittent may be caused by any of the following conditions: Thoroughly check any circuitry that is suspected of causing the intermittent complaint. Refer to Intermittents and Poor Connections Diagnosis in Wiring Systems. If a repair is necessary, refer to Wiring Repairs or Connector Repairs in Wiring Systems. Test Description The number(s) below refer to the step number(s) on the diagnostic table. 2. This test checks if communication can be established between the scan tool and the VTD. If the scan tool cannot communicate with the VTD, refer to Diagnostic System Check – Theft Deterrent in Theft Deterrent. 3. This test checks for any opens in the serial data circuit between the VCM and the VTD. This also checks for any intermittent malfunctions associated with the serial data circuit. 4. This step is to determine if the condition that set the DTC is still present. The engine must be cranked in order to set this DTC. If the condition is present, the engine will start and then stall, indicating the VCM is disabling fuel. 7. Use a scan tool to clear and check for any DTCs in all the modules connected to the Class 2 Serial Data circuit (VCM, VTD, ATC, and BCM). the module itself. After repairing the cause of DTC P1626, clear all DTCs from the systems capable of storing this DTC and DTC U1192. 1 Important: Before clearing the DTCs, use the scan tool Capture Info to save the Freeze Frame and Failure Records for reference. The control module’s data is deleted once the Clear Info function is used. Did you perform the Powertrain On-Board Diagnostic (OBD) System Check? — Go to Step 2 Go to Powertrain On Board Diagnostic (OBD) System Check 2 1. Install the scan tool. 2. Turn ON the ignition leaving the engine OFF. 3. Attempt to establish communications with the VTD (Passlock) Control Module. Does the scan tool communicate with the VTD (Passlock) Control Module? — Go to Step 3 Go to Diagnostic System Check – Theft Deterrent in Theft Deterrent 3 Check the Class 2 Serial Data circuit for the following intermittent conditions: Did you find a problem? • An open in the Class 2 Serial Data circuit between the VCM and the VTD (Passlock) Control Module. • A short to ground. • A short to voltage. • Loose or damaged terminals at the DLC, VCM or the VTD (Passlock) Control Module. — Go to Step 6 Go to Step 4 4 1. Turn OFF the ignition. 2. Connect or install any connectors or components that were disconnected or removed. 3. Clear all DTCs using a scan tool. 4. Turn OFF the ignition for 15 seconds. 5. Attempt to start the engine. Does DTC P1626 reset? — Go to Diagnostic System Check – Theft Deterrent in Theft Deterrent Go to Step 5 5 This DTC is intermittent. Are any additional DTCs stored? — Go to the applicable DTC table Go to Diagnostic Aids 6 Repair the circuit as necessary. Refer to Wiring Repairs or Connector Repairs in Wiring Systems. Is the action complete?


DIAGNOSTIC SYSTEM CHECK – THEFT DETERRENT Test Description The number(s) below refer to the step number(s) on the diagnostic table. 2: Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit. The specified procedure will determine the particular condition. 5: The presence of DTCs which begin with “U” indicate some other module is not communicating. The specified procedure will compile all the available information before tests are performed. 6: The listed DTCs are internal module malfunctions and should be corrected before attempting any other diagnostics. 7: The listed DTCs are battery voltage related malfunctions and should be corrected before attempting any other diagnostics. Diagnostic System Check – Theft Deterrent Step Action Yes No 1 Install a scan tool. Does the scan tool power up? Go to Step 2 Go to Scan Tool Does Not Power Up in Data Link Communications 2 1. Turn ON the ignition, with the engine OFF. 2. Attempt to establish communication with the body control module (BCM) and the powertrain control module (PCM). Does the scan tool communicate with the specified modules? Go to Step 3 Go to Scan Tool Does Not Communicate with Class 2 Device in Data Link Communications 3 1. Access the Class 2 Power Mode parameter in the Diagnostic Circuit Check menu on the scan tool. IMPORTANT: Important: The engine may start during the following step. Turn OFF the engine as soon as you have observed the Crank power mode. IMPORTANT: Insure that all ignition switch positions are observed


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
