SUBJECT:ECM REPROGRAMMING FOR ENGINE KNOCKING NOISE − SERVICE CAMPAIGN
PURPOSE During cold start, the engine ECU may order inappropriate fuel amounts which may cause engine noise. This campaign bulletin instructs dealers to reprogram the ECM with new software on all affected vehicles. In rare cases, if the vehicle exhibits an engine knocking noise, the engine may need to be replaced.
AFFECTED VEHICLES Certain 2014 - 2015 Mirage vehicles built before February 18, 2015
IMPORTANT: To maximize customer satisfaction with the quality of their vehicle, affected new or used inventory vehicles should be remedied before the vehicle is delivered. Dealers must check their inventory vehicles’ VINs on the Warranty Superscreen to verify whether the vehicle is involved in this service campaign.
CUSTOMER NOTIFICATIONS A letter will be sent to all owners of affected vehicles requesting they schedule an appointment with their local Mitsubishi dealer to have their vehicle remedied.
REQUIRED OPERATIONS Before starting this campaign procedure, CHECK THE WARRANTY SUPERSCREEN to verify if the vehicle is an affected VIN for this campaign and this campaign procedure has not already been completed.
1. Confirm your MUT-III is updated with the latest reprogramming database.
2. Reprogram the ECM with the new software. Refer to the ECM Reprogramming Chart for new software information.
IMPORTANT: If an affected vehicle has a Malfunction Indicator Lamp (MIL) illuminated before reprogramming, and DTCs are listed in the ECM memory, diagnose and repair those DTCs per the service manual before reprogramming. DO NOT reprogram the ECM until the reason(s) for other DTCs being set is corrected.
