6-54K-R06, 6-54E-R10, 6-54J-R11, 6-54M-R11, 6-53F-R10, 6-53E-R10, 6-53G-R10

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:

The “Check Engine” Malfunction Indicator Lamp (MIL) may illuminate and Diagnostic Trouble Code (DTC) P0420 may be stored in continuous memory. There may be no driveability concerns present. This TSB article has been coded on OASIS to enable this service repair to be performed on all referenced calibrations.

ACTION:

Reprogram or replace the PCM of all affected vehicles. Refer to the following Service Procedure for details.

NOTE:DEALERS WITH SERVICE BAY DIAGNOSTIC SYSTEM (SBDS) ARE REQUIRED TO OBTAIN REGIONAL APPROVAL WHEN IT IS NECESSARY TO REPLACE THE PCM.

NOTE:ALL VEHICLES WITH AFFECTED CALIBRATIONS SHOULD RECEIVE THE UPDATED SERVICE CALIBRATION.

SERVICE PROCEDURE

  1. For all customer concerns except MIL On, conduct normal diagnostics and repair as required. Upon completion of repairs, proceed to Step 3. For MIL On concerns, proceed to Step 2.
  2. Perform an EEC Diagnostic Quick Test to check for DTCs in memory:
    • For all DTCs present except P0420, complete normal diagnostics and repair as required, then go to Step 3. Refer to the appropriate 1996 Powertrain/Drivetrain Service Manual and the 1996 Powertrain Control/Emissions Diagnosis (PC/ED) On-Board Diagnostics II (OBDII) Service Manual for detailed diagnostic and repair procedures.
    • For DTC P0420, complete normal diagnostics and repair as required. If no repairs were indicated, proceed to Step 3. If repairs were required, first proceed to Step 3, then verify the concern was resolved after the PCM has been programmed by rechecking for DTCs after completing a test drive of the vehicle using the following drive cycle:

    —Allow the vehicle to reach normal operating temperature.

    —Accelerate moderately (1/2 to 3/4 throttle) to 97-105 km/h (60-65 mph).

    —Cruise at 97-105 km/h (60-65 mph) for a minimum of 1 minute (must be on a level road or up a slight grade) using steady throttle pressure.

    —Decelerate rapidly to 56-64 km/h (35-40 mph).

    —Cruise at 56-64 km/h (35-40 mph) for 1 minute (must be on a level road) using steady throttle pressure.

    —Repeat 4 times.

    If P0420 reoccurs, repair as required.

  3. Check decal to verify vehicle does not have the R12 calibration. If it does not, reprogram the PCM with the appropriate calibration per the following Application Chart using the latest calibration update 1996 CD-ROM or later.

    NOTE:PCM CALIBRATION 6-54K-R12 (OLD CALIBRATION 6-54K-R06) WILL NOT BE AVAILABLE FOR SBDS CD-ROM UNTIL 8/1/96.

    Obtain an Authorized Modifications Decal and list the date, dealer number, and summary of alterations 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.
