ISSUE:
Powertrain Control Modules (PCMs) no longer need to be replaced when
servicing driveability concerns. The only time a PCM needs
replacing is when it can no longer be reprogrammed and/or is
damaged. In all other cases, the PCM must be reprogrammed and
NOT REPLACED.
ACTION:
Use the following Service Procedure to properly reprogram a PCM.
SERVICE PROCEDURE
PCM REPROGRAMMING USING SBDS
- At the Main menu, select Powertrain and
enter the Vehicle Identification Number (VIN). Select
"Continue."
- From the Powertrain menu, select
Electronic Engine category.
- Scroll through the "Tool List" to PCM
Reprogramming and select "Continue."
- Any TSBs or Recalls for the entered
vehicle will be displayed. There is up to a 6 week delay for
TSB/Recall information updates on SBDS. New TSB/Recalls may
not appear or only the TSB number will be displayed even though the
new calibration is on the current calibration CD-ROM. Also, if
the vehicle calibration is being updated because of a Special
Service Message, Broadcast Message or the PCM was replaced and
requires a calibration, no screen may appear. This is not a
concern and will not prevent programming updates or being paid for
programming updates.
- Follow all hook-up instructions and
continue as prompted to the calibration screen. Typically, a
list of calibration numbers will appear. Answer as appropriate
for the vehicle and select "Continue." SBDS will then validate
the information entered against the information read in the PCM, and
any mismatch of software or hardware will be displayed for
technician action.
- Insert the proper calibration or the
latest level CD-ROM when prompted and follow the instructions as
displayed by SBDS. Do not crank the engine. SBDS will
update the engine calibration to the latest level calibration for
the selected calibration.
- After programming is complete, SBDS will
display a representation of the Authorized Modification Decal with
the Engineering Part Number for the PCM installed. It is
important that the label be completed and attached to the vehicle.
SBDS will also automatically print a copy of the vehicles log for
filling with the Repair Order.
- Selecting "Continue" will call for a KOEO
self test. Any hard faults present after performing self test
were not caused by programming. The calibration has now been
validated and the PCM is operating properly. Unless directed
by other Service Procedures, the vehicle can be released to the
customer.
PCM REPROGRAMMING WITH SBTS/NGS
- Select "NGS," then follow procedure
"Touring PLM Recalibration."
- Be sure to use cable with oversized DCL
connector. The oversized connector incorporates an 18-volt
transformer supplying the required voltage to reprogram the PCM.
