DESCRIPTION

Some vehicles may experience an engine idle drop when the A/C cycles on and off (normal operation) at a stop. Body vibration may also be felt.

The PCM software has been revised to eliminate this concern. Customers having this concern should have their vehicle repaired using the following repair procedure.

NOTE: When reprogramming the PCM of the 2007 Mazda3 with 2.3L (L3) engine and automatic transmission, the TCM also needs to be reprogrammed.

REPAIR PROCEDURE

1. Reboot the IDS to clear memory before reprogramming.
2. Using IDS 50.4 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. Fill out an Authorized Modifications label (P/N 9999-95-AMDC-97) with the new PCM calibration information, your dealer code, and todays date.

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