ECM REPROGRAM INTERRUPTION RECOVERY
NOTE:
This procedure is used when the reprogramming stops (is interrupted) before ECM (Engine Control Module) reprogramming is 100% complete.
While performing ECM (Engine Control Module) reprogramming, the reprogramming may stop (become interrupted) before it is 100% complete.
In many cases, reprogramming recovery is possible and the ECM may not need to be replaced if the complete ECM part number has been registered into the ECM before reprogramming stopped.
This ECM Reprogram Interruption Recovery General Procedure applies to Technical Service Bulletins that include ECM reprogramming published in April 2010 and later.
ECM Reprogramming Recovery Procedure
- Turn the ignition OFF (keep it off for at least 10 seconds).
- 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.
- 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
- Set the battery charger at a low charge rate.
- 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.
- Use the USB cable to connect the Vehicle Interface (VI) to the C-III computer and then connect the VI to the vehicle.
- 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.NOTE: It is likely that the engine cooling fans will come ON when the ignition is turned ON. If the fans are running, they will continue to run the entire time you are performing the reprogramming recovery procedure. - Open/start ASIST on the C-III computer, then select CONSULT Utilities > CONSULT III.
- Wait for the "Detecting VI/MI in progress" message to clear (picture not shown).
- Select the "Detected VI" from the list (see Figure 2).
- Select Connect (see Figure 2). Step 7 Step 8 Figure 2
- Wait for the "Checking the firmware version" message to clear (picture not shown).
- Select the correct Vehicle Name and Model Year (see Figure 3 for example). NOTE: Do not use the "Reprogramming / Programming" selection.
- Select (see Figure 3).
- Make sure the correct vehicle is displayed under Vehicle Selection: Confirmation Vehicle (see Figure 4 for example).
- Select Confirm (see Figure 4).
- Select Repair (see Figure 5).
- Select Direct Diagnostic Mode (see Figure 6).
- Select Reprogramming (see Figure 7).
- On your C-III screen, look at the Part Number column (see Figure 8 for example):
- If this column is blank, the ECM is damaged and cannot be recovered or ECM recovery is not available. Install a new ECM in the vehicle and program it to the latest version. Make sure to input the VIN as part of the process.
- If a Part Number is listed, select it and continue with the reprogramming recovery procedure. NOTE: The Engine Part Number on your C-III screen will read as follows:
- ENGINE 23710-xxxxx to 23710-xxxxx_xxx_xxMY_Alert!_For_ECM_Recovery_Only
- Select Next (see Figure 8).
- During data transfer, the screen in Figure 9 is displayed. CAUTION: During data transfer: CAUTION:
- DO NOT disturb the VI, DDL, or USB connections.
- DO NOT try to start the engine or turn the ignition OFF.
- The engine fans may be running. This is normal.
NOTE:- If "Transfer To VI" reaches 100% and "Transfer To ECU" does not start, or
- The error in Figure 10 displays.
- Check / make sure the battery voltage is above 12 V and all vehicle electrical loads are turned OFF (except the engine cooling fans). See Page 2, Step 3 or Page 3, Step 4 as it applies.
- Select Cancel Data Transmission, then click on the "Home" icon (upper left corner of the C-III screen) and try recover again (go back to Page 4, Step 6).
- When the screen in Figure 11 appears, ECM reprogramming is complete.
NOTE:
Erase DTCs from all systems
NOTE: During reprogramming, DTCs will set in several systems. DTCs must be erased from all systems. - Click on the "Home" icon (top left corner of the C-III screen). See Figure 13.
- Wait for the "Detecting VI/MI in progress" message to clear (picture not shown).
- Select the detected VI from the list (see Figure 13).
- Select Connect (see Figure 13).
- Wait for the "Checking the firmware version" message to clear (picture not shown).
- Select the correct Vehicle Name and Model Year (see Figure 14).
- Select (see Figure 14).
- 28. Make sure the correct vehicle is displayed under Vehicle Selection: Confirmation Vehicle (see Figure 15 for example).
- Select Confirm (see Figure 15).
- Select Diagnosis (see Figure 16).
- Wait for System Call to complete and CAN Diagnosis to reach 51% (see Figure 17 for example).
- When the CAN diagnosis reaches 51%, the process icons in the Process Guide Area at the top of the screen will light (become enabled).
- When the icons light, click on the "Final Check" icon (see Figure 17).
- CAN diagnosis will run again. When it reaches 51% and the icons light, click on the "Duplication Test" icon (see Figure 18).
- When the screen in Figure 19 appears, click on All Erase.
- Click on Yes (see Figure 19).
- 34. 35. 36. Use the scroll bar to scroll down the page and make sure all DTCs are erased (see Figure 19).
- For any DTCs that do not erase: diagnose, perform repairs, and erase DTCs.
- Refer to the Service Manual as needed.
Reprogramming is finished. Continue with the procedure on the next page.
- Close C-III, and then turn the ignition OFF.
- Make sure the throttle is released and your foot is NOT pressing the brake or clutch pedal.
- Operate the ignition as shown in Figure 20.
- The above ignition cycle will reset ECM self learned Data.
- 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.
- If idle speed is too low, perform Idle Air Volume Learning (IAVL). See the appropriate Service Manual (ESM) for this procedure.
- Test drive the vehicle; make sure it is operating correctly and the MIL is OFF.
- If the MIL comes ON; diagnose, repair, and erase DTCs.
- Refer to the Service Manual as needed.
