Overview:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module
(PCM) with new software.

Symptom/Condition:
The following enhancements are included with this software:
The vehicle operator may experience a MIL illumination. Further diagnosis may determine that
the MIL was caused by one or more of the following erroneous Diagnostic Trouble Codes
(DTC’s):

P0320 – No Crank Reference Signal At PCM
P1494 – Leak Detection Pump Switch Or Mechanical Fault

Diagnosis:
Using a Scan Tool (DRBIIIT) with the appropriate Diagnostic Procedures Manual, verify all
engine systems are functioning as designed. If DTCs are present record them on the repair
order and repair as necessary before proceeding further with this bulletin.

If the vehicle operator describes or experiences the Symptom/Condition, perform the Repair
Procedure.

Parts Required:

Qty. Part No. Description

1 04275086AB Label, Authorized Modification

Special Tools/Equipment Required:

NPN	Battery Charger
CH2002	General Purpose Interface Bus Cable Assembly
CH6000A	Scan Tool (DRBIII)
CH7000A/7001A	J1962 Cable with red DRBIII connector
	TechCONNECT Workstation

NOTE: An updated J1962 cable has been released. This cable has a red colored
connector at the DRBIII connection. Use this cable whenever a flash is being
performed.

Repair Procedure:

NOTE: Whenever a controller is programmed, the software in the DRBIII; must be
programmed with the latest revision level available.

NOTE: If this flash process is interrupted/aborted, the flash should be restarted and
then follow the directions on the DRBIII.

The reprogramming procedure requires access to software and equipment that most owners do not have. The very long and involved programming procedure will not be posted here. To see the specific instructions, you can obtain or view a copy of this TSB at your dealership.

NOTE: Due to the PCM programming procedure, a DTC may be set in other modules
(TCM, BCM, MIC, SKIM, etc.) within the vehicle, if so equipped. Some DTC’s
may cause the MIL to illuminate. Check all modules using “Module Scan”,
record the DTC’s, and erase these DTC’s prior to returning the vehicle to the
customer. Erase any DTC’s in the PCM only after all other modules have had
their DTC’s erased.

NOTE: The following step is required by law.

Type the necessary information on the “Authorized Modification Label” p/n 04275086AB
and attach near the VECI label (Fig. 1).
