MULTI-MODEL - MIL ILLUMINATION WITH DTC P0128

BULLETIN NOTE

This bulletin supersedes the previous bulletin issued on 01/11/06. The APPLICABLE MODELS and CALIBRATION INFORMATION have been revised.

APPLICABLE MODEL(S)/VINS

2004 – 2005 Mazda3 vehicles

2006 Mazda5 vehicles with VINs lower than JM1CR**** ** 129901 ( produced before June 12, 2006)

DESCRIPTION

Some vehicles may experience the MIL illumination with DTC P0128 (Coolant Thermostat Stuck Open) stored in memory. This condition may be caused by improper PCM calibration.

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

REPAIR PROCEDURE

1. Reboot the PDS/IDS PTU to clear memory before reprogramming.
2. Using PDS/IDS 44.1 or later software, reprogram the PCM to the latest calibration (refer to “Calibration Information” table) by following the “Module Reprogramming” procedure.

NOTE:

3. After performing the PCM reprogramming procedure, verify the repair by starting the engine and making sure there are no MIL illumination or abnormal warning lights present.

NOTE:

4. For Madza3 vehicles built prior to February 1, 2004 (VIN: JM1BK **** ** 149352), perform the following additional work:
  1. Allow vehicle to cool down overnight. Drive vehicle and check if MIL (DTC P0128) comes ON.

    • If the MIL still comes ON with DTC P0128, replace thermostat with a modified part according to Workshop Manual (section 01-12 THERMOSTAT REMOVAL/INSTALLATION).

5. Fill out an “Authorized Modifications” label (P/N 9999-95-AMDC-97) with the new PCM calibration information, your dealer code, and today's date.

6. Place the “Authorized Modifications” label on the “A” pillar below the tear tag in the driver door jamb.
