ECM Tune Download Procedure

AFFECTED VEHICLE RANGE:

Range Rover (LM) All

SITUATION:

CLARIFICATION OF TUNE DOWNLOAD PROCEDURE REQUIRED

93

A number of situations may require the reloading of the Engine Control Module (ECM) tune on Range Rover vehicles. Because there are several

areas of potential confusion in this process, it is possible for an incorrect procedure to be followed, disrupting the download and requiring multiple

attempts.

RESOLUTION:

FOLLOW CLARIFIED STEP-BY-STEP PROCEDURE

NOTE:

Whenever "compulsory" tunes are issued on a T4 disc, the T4 will initiate an automatic update process that the Technician should follow to its

conclusion. "Non-compulsory" tunes associated with certain service procedures will require the use of this TIB for guidance through the tune

installation process.

Review and follow the illustrated procedure in this TIB whenever a "non-compulsory" download of a new ECM tune is performed. The

Technician will need to follow these instructions to manually select the tune for download. Note the definition of the term "ASSEMBLY" in the

context of T4 on-screen instructions:

"ASSEMBLY" = INSTALLED ECM HARDWARE plus T4 DOWNLOADED SOFTWARE

PARTS INFORMATION:

No parts required

DDW WARRANTY CLAIMS:

Information Only

Normal warranty policy and procedures apply.

Material allowance is included in labor operation.

REPAIR PROCEDURE

CLARIFICATION TO NEW RANGE ROVER ENGINE ECU TUNE UPDATE PROCESS

1. To program engine ECU insert disc "Range Rover 12" or later.

^ Begin a diagnostic session.

^ Click [vehicle configuration] from main menu.

^ Then on this screen select "EMS ECU checks".

94

2. Verify the battery voltage is fully charged (12 volts or greater).

NOTE:

The battery must be capable of maintaining full charge during this process which is expected to take 15 - 18 minutes total.

3. Connect a battery charger set on low amp current charge to maintain battery state during this process.

4. When the battery condition is satisfactory and the charger connected, click "Continue."

NOTE:

T4 will check the engine ECU for available programming records. If the ECU is full T4 will prompt for replacement.

5. Click "Continue."

NOTE:

This screen is NOT relevant for vehicles that only need the tune update.

95

6. Click "Continue.

NOTE:

This screen is NOT relevant for the update.

7. Click "NO"

NOTE:

An "ASSEMBLY" is defined as the combination of HARDWARE + SOFTWARE. By changing the TUNE the ASSEMBLY will also be

changed.

8. Click "YES."

NOTE:

If "View Fixes" is clicked, T4 will return to the previous screen.

96

9. Click "Confirm Fix" to continue.

NOTE:

This screen identifies which tune is being installed. Technical Information Bulletins or other documentation will list a specific "Assembly"

or software level which can be verified here. If the correct Assembly is not listed verify the following:

^ The correct diagnostic CD is being used to perform the tune update.

^ Other unexpected issues may have caused T4 to select the incorrect tune.

10. If you do not have the correct assembly number, contact Land Rover Technical Helpline.

11. If you get the proper assembly number click "Continue."

NOTE:

T4 will commence the ECU tune download. This screen will indicate the progress. The % download is indicated at the top of screen

indicating that the process is active and T4 has not locked up. When done AFTER approximately 15 minutes, the page will advance to a

"Download Complete" with some details displayed.

12. If there is an incomplete download, "Download Failed" will display. Follow the instructions displayed by T4 carefully to complete ECM

programming.

13. If the additional attempts fail repeatedly, there, may be an ECM or other mechanical vehicle issues. Investigate the vehicle for the problem.

14. To verify that the programming has been completed, go to the main T4 menu and select: System Diagnosis, Petrol Engine Management,

97

Vehicle Maintenance, Programming History.
