Ford Mustang (1999-2004) Service Manual: Spring Codes

Spring Codes

The spring code portion of the vehicle certification (VC) label identifies both the front and rear springs.

The first letter/number indicates the front spring code. The second letter/number indicates the rear spring code.

  • Front springs - base part number - 5310 (RH/LH)
  • Rear springs - base part number - 5560 (RH/LH)

Powertrain Calibration Information

Powertrain Calibration Information

NOTE: Powertrain calibration information is limited to a maximum of five characters per line on the Vehicle Certification Label. Because of this, calibration identification consisting of more than five characters will wrap to the second line on the VC label.

Powertrain calibration information is printed in the lower right corner of the Vehicle Certification Label.

Only the base calibration information is printed. Revision levels will not appear, however, this information can be found in the On Line Automotive Service Information System (OASIS). For the current model year, Ford Motor Company is using three different protocols which describe powertrain base calibration. These protocols are designed to provide worldwide standardization for vehicle calibration. If the electronic calibration strategy has been used since 1998 and carried into the current model year, protocol 1 will be used. Refer to Protocol 1 below. If the electronic calibration strategy has been used since 1999 and is carried into the current model year, protocol 2 will be used. Refer to Protocol 2 below. For new electronic calibration strategies introduced since the 2000 model year, use protocol 3. Refer to Protocol 3 below.

Protocol 1

Protocol 1

 

Item Description
1 Model year (model year in which calibration strategy was first introduced)
2 Engine code
3 Engine revision level

Protocol 2

Protocol 2

 

Item Description
1 Model year (model year in which calibration strategy was first introduced)
2 Engine code
3 Transmission code
4 Emission standard (designates the specific country emission standard)
5 Design level (design level assigned to the engine)

Protocol 3

Protocol 3

 

Item Description
1 Model year (model year in which calibration strategy was first introduced)
2 Vehicle code
3 Transmission code
4 Unique calibration (designates different hardware to similar vehicles). Example: tires, drive ratios, etc.
5 Fleet code (describes fleet to which the vehicle belongs). Example: 6 - evaporative emissions
6 Certification region (lead region where multiple regions are included in one calibration).

Example: A - U.S. federal
7 Revision level (will advance as revisions occur). Not printed on label

Protocol 3

The following offers a more detailed explanation of the coding strategy used for protocol 3.
