ECM Reprogram Interruption Recovery (1SX1)

ECM Reprogramming Recovery Procedure

1. Turn the ignition OFF (keep it off for at least 10 seconds).
2. Close / turn OFF the CONSULT-III (C-III) program.
   IMPORTANT: Before performing the reprogram interruption recovery, make sure:

   • ASIST on the C-III computer has been freshly synchronized (updated).
   • All C-III software updates (if any) have been installed.
     NOTE: The C-III computer automatically gets applicable ECM reprogram recovery data during ASIST synchronization.
3. Make sure the following are connected:
   • Use the USB cable to connect the Vehicle Interface (VI) to the C-III computer and then connect the VI to the vehicle.
     CAUTION: For ECM reprogramming, be sure to have the C-III computer 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.
   • Connect the AC Adapter to the C-III computer.
     CAUTION: Be sure to connect the AC Adapter. If the C-III computer battery voltage drops during reprogramming recovery, the process will be interrupted and the ECM will be damaged.
   • 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 recovery, the ECM will be damaged.

     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 recovery. If the battery voltage drops during reprogramming recovery, the ECM will be damaged.
4. Turn the ignition ON with the engine OFF.
   • The engine must be OFF (not running) during the reprogram recovery procedure.
   • For Hybrid vehicles, Make sure the dash warning lights are ON and the "READY" light is OFF (see Figure 1). READY light should be OFF (not visible) Figure 1
   • 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 recovery starts, reprogramming recovery will not complete.
