B4000 Regular Cab 4WD V6-4.0L OHV (1997)
4.
Use WDS to verify whether a later calibration is available.
^
If the vehicle already has the latest calibration, refer to the workshop manual troubleshooting and repair information.
^
If a later calibration is available (refer to "Calibration Information" table), reprogram the PCM using WDS B12M or later software by
following the "Module Reprogramming" procedure.
NOTE:
^
Always update the WDS PTU first, then install the needed calibration file that WDS shows during PCM reprogramming. Go to "WDS
Calibration" on ESI and download the "update" file. If the PTU is not updated to the latest WDS calibration level, the calibration file will not
install into the PTU.
^
WDS shows the calibration part numbers after programming the PCM.
^
Please be aware that PCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of WDS
software, and additional revisions made to those calibrations for service related concerns.
^
When reprogramming a PCM, WDS will always display the "latest" calibration P/N available for that vehicle. If any calibration has been
revised/updated to contain new information for a new service concern/issue, it will also contain all previously released calibrations.
^
When performing this procedure, if the WDS PTU is not docked and connected to 115V-120V, we recommend that a battery charger be
installed on the vehicle battery and turned ON to a maximum charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If
you exceed 20 AMPS, it will damage the WDS PTU.
^
Install an "Authorized Modification" label (P/N 9999-95-AMDC-97) with the new calibration information next to the Emission Control sticker
on the radiator support. The "Authorized Modification" label will inform technicians of the PCM calibration change if future repairs are
necessary.
5.
Verify repair.
NOTE:
After reprogramming a PCM, it is necessary to road test the vehicle to relearn KAM (Keep Alive Memory) strategy and verify no MIL
illumination or DTC's are present.
