J2534 Pass Thru Manufacturers

J2534 is a scan tool and reprogramming interface standard for all auto manufac-turers. All 2003 and newer vehicles are required to be J2534 compatible. TheJ2534 interface translates data between PC and vehicle network/data link. It isused for ‘Pass Thru’ reprogramming and scan tool communication.

Most OBDII vehicles, especially domestics, can be reprogrammed via J2534 PassThru. Each auto manufacturer has their own J2534 PC software for reprogram-ming. Calibrations and J2534 software are available either from auto manufactur-ers service information website or by purchasing a CD-ROM.

A lot of diagnostic time can be wasted on problems that are fixed with program-ming updates. OEM service websites have the most up to date TSB andrecalibration information. Common for updated calibration to address shiftingproblems, engine performance problems, parts interchange, and false DTC’s.

Needed:• J2534 Pass Thru interface.• PC with internet connection. PC must be connected to the internet

(online) and the J2534 Pass Thru interface at the same time.• Subscription to Motorcraft Module Reprogramming and Initialization.• Download and install Ford Module Programming software from

www.motorcraftservice.com (login required).

• You will probably be instructed to remove the fuel pump, cooling fan,and FICM (diesel application) relays or fuses. Familiarize yourselfwith their locations.

• Calibration information can be found in the “Latest Calibration” spreadsheet at www.motorcraftservice.com on the Reprogramming andInitialization page.

• Calibration number is the “Module ID” or “Module Part Number” retrievedwith a scan tool.

• Calibration can be found with the catchword, or with vehicle informationand current calibration number. Use “Latest Calibration” spreadsheet.Module programming software will automatically install the latestcalibration file.

• It takes about one hour to reprogram a Ford.

The “catchword” is a four character code on the PCM build/tear tag. It is usuallylocated on the PCM connector and is visible without having to remove the PCM.

Ford Recalibration

The catchword in this example is “BCL2”.Note that the catchword is printed in larger characters.

Use the latest calibration spreadsheet to look up calibration information usingeither the vehicle information (I.E. Year, model, engine size) or the catch code onthe PCM or a combination of both to help you narrow your search down.

The Ford Module Programming software also enables you to change configurationand settings on other vehicle systems, such as warning chimes, power door locks,key programming, speedometer calibration for tire size and axle ratio, etc.

Ford Module Reprogramming will also show any TSB’s related to calibration up-dates.

Note: Not all updated calibrations will have a TSB. It is commonfor Ford to update calibration with no TSB or reference as to whythe calibration was changed.

Other considerations:If the DCX2534 Update Manager program cannot be found, check:C:\Program Files\DaimlerChrysler and set file path accordingly.

TechAuthority website has a calibration software search where you can entereither the VIN, vehicle information, or current software number to get the mostcurrent software part numbers.

There is also a “Flash Matrix” table which lists the software calibration numberupdate history for each vehicle model.

Install the Calibration Update Wizard and VIN Update Wizard programs from thedisc.

Other considerations:

• If the Calibration Update Wizard program cannot be found, check: C:\Program Files\Toyota Diagnostics\Calibration Update Wizard\CUW.exe

• VIN may have to be programmed into module after reprogramming, use VINUpdate Wizard.

Resetting the Shift Adapts

• Ford: Disconnect battery for five (5) minutes (KAM reset), turn key on, andtouch battery cables together

• Ford AF21-B: Disconnect battery for 20 minutes.

• GM with Allison LCT 1000: Initiate FastLearn with scan tool, follow drivinginstructions given by scan tool.

• Other GM with EPC: Disconnect battery for at least 20 minutes.

• Chrysler with TE, LE, RLE, RFE transmission: Execute Quicklearn functionwith scan tool.

• Toyota and Lexus vehicles with “U” series transaxles: Perform PCM MemoryReset with scantool.

Many vehicles, specifically GM and Toyota, learn pressure up quickly, but learnpressure down very slowly. The result can be a harsh shifting transmission thatwill take a lot of driving to relearn, and may cause transmission damage in themeantime. It is always best to perform the proper reset and relearn functions toensure a good working unit and a happy customer.
