Replace the A/F sensor on the affected bank (related to the stored DTC). • For replacement procedure, refer to the appropriate Electronic Service Manual (ESM). 2. Next, connect the CONSULT PC to the vehicle to begin the reprogramming procedure. NOTE: • Most instructions for reprogramming with CONSULT-III plus (C-III plus) are displayed on the CONSULT PC screen. • If you are not familiar with the reprogramming procedure, click here. This will link you to the "CONSULT- III plus (C-III plus) ECM Reprogramming" general procedure. • Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume Learn (IAVL) conditions: ¾ Engine coolant temperature: 70 -100°C (158 - 212°F) ¾ Battery voltage: More than 12.9V (At idle) ¾ Transmission: Warmed up Figure A • After reprogramming is complete, you will be required to perform Throttle Valve Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC erase. CAUTION: • Connect a battery charger to the vehicle battery. If the vehicle battery voltage drops below 12.0V or above 15.5V during reprogramming, the ECM may be damaged. • Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load remains ON, the ECM may be damaged. • Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during reprogramming, the process will be interrupted and the ECM may be damaged. • Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the CONSULT PC and the VI. If Bluetooth® signal waves are within range of the CONSULT PC during reprogramming, reprogramming may be interrupted and the ECM may be damaged. 3/5 ITB11-054a 3. Open ASIST on the CONSULT PC and start C-III plus. 4. Wait for the plus VI to be recognized / connected. • The serial number will display when the plus VI is recognized / connected. 5.
