CONTROL MODULE PROGRAMMING

Note. When battery is disconnected and reconnected, some abnormal drive symptoms may occur while vehicle relearns its adaptive strategy. Vehicle may need to be driven for approximately 10 miles or more to relearn strategy.

Some control modules require programming after replacement for proper system operation. See appropriate application table for programming information. If replacing a programmable module, see PROGRAMMABLE MODULE INSTALLATION PROCEDURE . Some modules have the ability to have customer preferences configured such as belt minder, chimes, autolock/relock, etc. For programming customer preferences, see appropriate articles in ACCESSORIES & EQUIPMENT.

Note. Central security module may also be referred to as a vehicle security module.

CONTROL MODULE APPLICATION (ZX2)

PROGRAMMABLE MODULE INSTALLATION PROCEDURE

Note. NGS tester will only store module configuration information for 24 hours.

Prior to removal of applicable programmable module, perform Programmable Module Installation (PMI) procedure by uploading module configuration information to New Generation Star (NGS) tester using manufacturer's instructions. Once new programmable module has been installed in vehicle, download module configuration information from NGS tester into new module. On some models, module configuration information is also retained in Powertrain Control Module (PCM). If module information cannot be accessed from module, use NGS tester with Ford Service Function (FSF) card and flash cable to upload module configuration information from PCM following scan tool instructions.

PROGRAMMING POWERTRAIN CONTROL MODULE (ALL MODELS)

Note. Before performing PCM programming procedure, check for any applicable Technical Service Bulletins (TSBs) that may apply to vehicle application.

Description

All OBD-II scan tools support Powertrain Control Module (PCM) reset. The PCM Reset allows the scan tool to command the PCM to clear all emission-related diagnostic information. When resetting the PCM, a DTC P1000 will be stored in the PCM until all the OBD-II system monitors or components have been tested to satisfy a drive cycle, without any other faults occurring. See DRIVE CYCLES in appropriate SELF-DIAGNOSTICS article.

The following events occur when a PCM reset is performed

  1. Clears the number of Diagnostic Trouble Codes (DTCs).
  2. Clears the DTCs.
  3. Clears the freeze frame data.
  4. Clears diagnostic monitoring test results.
  5. Resets status of the OBD-II system monitors.
  6. Sets DTC P1000.

Resetting Keep Alive Memory (KAM)

Note. This function may not be supported by all scan tools. Refer to scan tool manufacturer's instruction manual.

Resetting Keep Alive Memory will return PCM memory to its default setting. Adaptive learning contents such as idle speed, refueling event, and fuel trim are included. A PCM Reset (described above) is also part of a KAM Reset. Both can be useful in post repair retest.

After Keep Alive Memory has been reset, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveability and performance.

If an error message is received or the scan tool does not support this function, disconnecting the battery ground cable for a minimum of 5 minutes may be used as an alternative procedure.

FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (FLASH EEPROM)

Note. If using a generic scan tool, follow scan tool manufacturer's instructions to perform FLASH VEHICLE IDENTIFICATION (VID) BLOCK PROCEDURE.

Flash Electrically Erasable Programmable Read Only Memory (EEPROM) is contained in an Integrated Circuit (IC) internal to the PCM. The EEPROM contains the vehicle strategy including calibration information specific to the vehicle and is capable of being reprogrammed or reflashed repeatedly.

As part of the calibration there is an area referred to as the Vehicle Identification (VID) block. The VID block must be programmed when replacing the PCM as described under Programming the VID Block for a Replacement PCM. Failure to perform this procedure may generate fault codes: P1635, P1639, VID Block not programmed or is corrupt. The VID block in an existing PCM can also be tailored to accommodate various hardware/parameter changes made to the vehicle since production. Failure to perform this procedure properly may generate fault code: P1635, Tire/Axle Ratio out of Acceptable Range is one of the main causes for code: P1639. This is described under Making Changes to the VID Block and also under Making Changes to the PCM Calibration. The VID block contains many items used by the strategy for a variety of functions. Some of these items include the VIN number, octane adjust, fuel octane, fuel type, vehicle speed limit, tire size, axle ratio, the presence of speed control and four wheel drive electronic shift on the fly versus manual shift on the fly. Only items applicable to vehicle hardware and supported by the VID block will be displayed on the scan tool.

When changing items in the VID block, the strategy will place range limits on certain items such as tire and axle ratio. The VID block is also limited to the number of times to be reconfigured. When this limit is reached, the scan tool will display a message indicating the need to flash the PCM again to reset the VID block.

The following procedures use the Worldwide Diagnostic System (WDS) for reprogramming

  1. «PROGRAMMING VID BLOCK FOR REPLACEMENT PCM»(/mercury/grand-marquis/iv-2002-2005/remont/computer-relearn/#computer-relearn-procedures__programming-vid-block-for-replacement-pcm)
  2. «MAKING CHANGES TO THE VID BLOCK»(/mercury/grand-marquis/iv-2002-2005/remont/computer-relearn/#computer-relearn-procedures__making-changes-to-the-vid-block)
  3. «MAKING CHANGES TO THE PCM CALIBRATION»(/mercury/grand-marquis/iv-2002-2005/remont/computer-relearn/#computer-relearn-procedures__making-changes-to-the-pcm-calibration)

Reprogramming can be performed by a local Ford dealer for any non Ford facility. There are other Enhanced Scan Tools that may have reprogramming capabilities available. Refer to the manufacturers users manual for details.

Programming VID Block For Replacement PCM

A new PCM will contain the latest strategy and calibration level for a particular vehicle. However, the VID block will be blank and will need programming. There are 2 procedures available. The first is an automatic data transfer from the old PCM to the new PCM and the second is manual data entry into the new PCM.

Automatic data transfer will be performed if the old PCM is capable of communicating. This is done by the use of a scan tool to retrieve data from the old PCM before removing it from the vehicle. The stored data can now be downloaded to the new PCM after it has been replaced.

Manual data entry must be performed if the old module is damaged and/or incapable of communicating. Remove and replace the old PCM. Using a compatible Scan Tool select and execute MODULE/PARAMETER REPROGRAMMING referring to the manufacturers users manual. Important, make certain that all parameters are included. Failure to properly program Tire Size in revolutions per mile, (rev/mile equals 63,360 divided by the tire circumference in inches) Axle Ratio, 4x4/4x2, and/or Manual/Electronic shift on the fly (MSOF/ESOF) may result in codes: P1635, P1639. You may be instructed to contact the AS BUILT data center for the information needed to manually update the VID block with the scan tool. Contact the center only if the old PCM cannot be used or the data is corrupt. For Ford Lincoln Mercury technician's, contact your National Hotline or the Professional Technician Society (PTS) web sight for AS BUILT data. Non Ford technicians, use the Fed World web site at fedworld.gov. Select AUTO SERVICE INFORMATION and search for CALIBRATIONS or VEHICLE CALIBRATIONS then specify vehicle manufacturer, model name and model year as required.

Making Changes To The VID Block

A PCM which is programmed may require changes to be made to certain VID information to accommodate vehicle hardware. Refer to PCM/MODULE REPROGRAMMING on the Scan Tool.

Making Changes To The PCM Calibration

At certain times, the entire EEPROM will need to be completely reprogrammed. This is due to changes made to the strategy or calibration after production or the need to reset the VID block because it has reached its limit. Refer to PCM/MODULE REPROGRAMMING on the Scan Tool.
