WARNING:
THIS MODIFICATION IS AUTHORIZED ONLY FOR THE LISTED ENGINE. PERFORMING THIS MODIFICATION ON OTHER ENGINE CALIBRATIONS IS UNAUTHORIZED AND COULD CREATE LIABILITY UNDER APPLICABLE FEDERAL OR LOCAL LAWS.
ISSUE:
A no start/hard start condition at temperatures below 16°C (60°F), and/or a surge between 56-68 km/h (35-42 mph) on a flat or slightly inclined road, using a light steady throttle, may occur on some vehicles. This may be due to the Powertrain Control Module (PCM) programming giving extra fuel during cranking causing the spark plugs to foul, and/or the torque converter clutch not having the appropriate engagement calibration.
ACTION:
Reprogram or replace the PCM. Refer to the following Service Procedure for details.
NOTE:
DEALERS WITH SBDS ARE REQUIRED TO OBTAIN REGIONAL APPROVAL WHEN IT IS NECESSARY TO REPLACE THE PCM.
SERVICE PROCEDURE
1. Verify the concern. Perform normal diagnostic routines and service as required.
2. If no other concerns are found after performing normal diagnostics or the concern still exists after service has been performed, reprogram or replace the PCM. Dealers with Service Bay Diagnostic System (SBDS), reprogram the PCM with the appropriate calibration per the calibration chart using the latest calibration update CD-ROM. If SBDS is not available, replace the PCM using the correct PCM from the Application Chart in this article.
Obtain an Authorized Modifications Decal and list the, date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
