CONSULT-III (C-III) ECM REPROGRAMMING

NOTE: A symptom based TSB is required before using this procedure.
IMPORTANT: Before starting, make sure:
  • ASIST on the CONSULT PC has been freshly synchronized (updated). 
  • All C-III software updates (if any) have been installed. 
NOTE: The CONSULT PC automatically gets applicable ECM reprogramming data during ASIST synchronization.
  1. Use the USB cable  to connect the Vehicle Interface (VI) to the CONSULT PC and then connect the VI to the vehicle.
    CAUTION: For ECM reprogramming, be sure to have the CONSULT PC connected to the VI with the USB cable. If the C-III computer is not connected to the VI with the USB cable, the ECM may be damaged. 
  2. Connect the AC Adapter to the CONSULT PC. 
    CAUTION: Be sure to connect the AC Adapter. If the CONSULT PC battery voltage drops during reprogramming recovery, the process will be interrupted and the ECM will be damaged. 
  3. Connect a battery charger to the vehicle battery: 

    For Conventional Vehicles 

    • Set the battery charger at a low charge rate.
      NOTE: The GR-8 (Battery and Electrical Diagnostic Station) set to "Power Supply" mode is recommended.
      CAUTION: Be sure the battery charger is connected securely to the battery. Make sure the battery voltage stays above 12 V during reprogramming. If the battery voltage drops during reprogramming, the ECM may be damaged.  NOTE: ECM recovery data may be available. CLICK HERE to link to the ECM REPROGRAM INTERRUPTION RECOVERY General Procedure.

      For Hybrid Vehicles 

    • Use the GR-8 - Battery and Electrical Diagnostic Station.
    • If needed, refer to Hybrid Service TSBs for connecting the GR-8 to the Hybrid 12V battery.
      CAUTION: DO NOT use a standard battery charger for Hybrid vehicles. Make sure to connect the GR-8 securely to the Hybrid 12V battery. Make sure the battery voltage stays above 12 V during reprogramming. If the battery voltage drops during reprogramming, the ECM may be damaged.  NOTE: ECM recovery data may be available. CLICK HERE to link to the ECM REPROGRAM INTERRUPTION RECOVERY General Procedure.
  4. Turn the ignition ON with the engine OFF.
    • The engine must be OFF (not running) during the reprogramming procedure.
    • For Hybrid vehicles, Make sure the dash warning lights are ON and the "READY" light is OFF. 
      G07662291
    • Turn OFF all vehicle electrical loads such as exterior lights, interior lights, HVAC, blower, rear defogger, audio, NAVI, seat heater, steering wheel heater, etc.
      IMPORTANT: Make sure to turn OFF all vehicle electrical loads. If the vehicle battery voltage drops below 12 V before reprogramming starts, reprogramming will not complete. After the "Transfer To VI" is complete, the reprogramming will stop, and "Transfer To ECU" will not start.
    • Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.) within range of the CONSULT PC and the VI.
      CAUTION: Make sure to turn off all external Bluetooth® devices. If Bluetooth® signal waves are within range of the CONSULT PC and the VI during reprogramming, reprogramming may be interrupted and the ECM may be damaged. 
  5. Make sure the engine cooling fan(s) are not  running.

    If the cooling fans are runnning:

    1. Turn the ignition OFF.
    2. Wait for the engine to cool.
    3. Turn the ignition ON (with engine OFF).
    4. Make sure the engine cooling fans are not running.
  6. Open / start ASIST on the CONSULT PC.
  7. Select CONSULT Utilities, CONSULT-III, and Wait for the "Detecting VI/MI in progress" message to clear.
  8. Select the detected VI from the list. (See Figure 1  .)
  9. Select Connect.  (See Figure 1  .)
    G07662292

      G07662310

    Reprogramming is finished. Continue with the Procedure below.

  38. Close C-III, and then turn the ignition OFF.
  39. Make sure the throttle is released and your foot is NOT  pressing either the brake or clutch (M/T) pedal.
  40. Operate the ignition as shown in Figure 19  .
    NOTE: For Hybrid vehicles, ignition ON = dash warning lights ON and the "READY" light OFF.

    OFF 10 seconds > ON 2 seconds > OFF 10 seconds > ON 2 Seconds > OFF 10 seconds 

    G07662311
    • The above ignition cycle will reset ECM self learned Data.
      NOTE: For Hybrid vehicles, skip to step 42  .
  41. Start the engine and check the idle speed.
    • If idle speed is too low, perform Idle Air Volume Learning (IAVL). See the appropriate Service Manual (ESM) for this procedure.
      NOTE: If the engine will not idle, hold the engine RPM at about 2000, then slowly bring it down to an idle. IAVL can now be performed.
  42. Test drive the vehicle; make sure it is operating correctly and the Check Engine light is OFF.
    • If the Check Engine light comes ON; diagnose, repair, and erase DTCs.
