Engine Controls - MIL ON/DTC P2110 Stored in PCM
Engine01-031/04
2003 MAZDA6 3.0L - MIL ILLUMINATION WITH
DTC P2110
APPLICABLE MODEL(S)/VINS
2003 Mazda6 3.0L vehicles produced before February 3, 2003
DESCRIPTION
Some vehicles may experience MIL illumination with DTC P2110 stored in PCM memory.
P2110: Throttle actuator control system -) forced limited RPM
DTC in PCM memory may be caused by improper PCM calibration.
Customers having this concern should have their vehicles repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Using WDS B32.0 or later software, reprogram the PCM to the latest calibration (refer to "Calibration Information" table) by following the "Module Reprogramming" procedure.
NOTE:
^ Always update the WDS PTU first, then install the needed calibration file that WDS shows during PCM reprogramming. Go to "WDS Calibration" on ESI and download the "update" file. If the PTU is not updated to the latest WDS calibration level, the calibration file will not install into the PTU.
^ It is not necessary to remove any fuses or relays during PCM reprogramming when the WDS screen prompts you to do so. You may accidentally stop power to one of the PCM terminals and cause the PCM to be blanked, or you may receive error messages during the WDS reprogramming procedure.
^ WDS shows the calibration part numbers 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.
^ When performing this procedure, if the WDS PTU is not docked and connected to 115V-120V, we recommend that a battery charger be installed on the vehicle battery and turned ON to a maximum charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If you exceed 20 AMPS, it will damage the WDS PTU.
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:
After PCM reprogramming, it is no longer necessary to road test the vehicle to "relearn" KAM (Keep Alive Memory).
4. Place an "Authorized Modification" label (P/N 9999-95-AMDC-97) with the new calibration information on the "A" pillar above the tear tag in the driver door jamb.
