01-023/02

2001 - 2002 TRIBUTE - ROLLING IDLE WITH HIGH AMBIENT TEMPERATURES

APPLICABLE MODEL(S)/VINs
2001-2002 Tribute 2.0L only.

DESCRIPTION
Some 2001-2002 Tribute equipped with a 2.0L engine and a manual transmission may exhibit a rolling idle condition in high ambient temperatures. This condition maybe caused by overly sensitive correction of the ignition timing control in the Powertrain Control Module (PCM) calibration.

Customers having this concern should have their vehicle repaired using the following procedure.

REPAIR PROCEDURE
1. Verify customer concern.

2. Follow normal diagnostics in the Workshop Manual (section 01-01 TROUBLESHOOTING).
^ If normal diagnostics do not reveal a root cause, re-program the PCM to the latest calibration. Proceed to STEP 3.

3. Perform the WDS "Module Reprogramming" procedure and reprogram the Powertrain Control Module with the latest calibration using WDS B19A or later software. For this procedure, refer to Service Bulletin 01-010/01R "Charging System Warning Lamp "ON" During Cold Temperatures".

4. Install revised PCM calibration sticker (9999-95-AMDC 97 available through MStore) in appropriate position (next to vehicle emissions label) with the calibration P/N provided in CALIBRATION INFORMATION.

5. Verify repair.

CALIBRATION INFORMATION
New PCM Calibration Part number is 1U7A-12A650-ANA. File name is DVAN92U.

NOTE:
^ WDS shows the calibration part number 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.
