SERVICE INFORMATION
^
In-vehicle ECM reprogramming is available to update the ECM of certain 1999 vehicles (listed in Applied Vehicles above), and all 2000 and later
vehicles.
^
This reprogramming allows the vehicle ECM to be upgraded to the latest operating specifications without removal or replacement of the ECM.
^
When an ECM has been reprogrammed it will display a new P/N on the CONSULT-II screen.
NOTE:
ECM reprogramming will not effect NATS.
^
ECM reprogramming requires the use of ASIST 8.0 or higher, and CONSULT-II with the ECU Reprogramming Software Card (orange color).
^
Use the Service Procedure steps to transfer ECM reprogramming data from the ASIST PC to CONSULT-II, and from CONSULT-II to the vehicle
ECM.
^
Refer to the ECU Reprogramming Software Operations Manual (in ASIST) for additional information on using CONSULT-II for ECM
reprogramming.
CAUTION
^
An ECM should be reprogrammed only when required by a specific Nissan Technical Bulletin, or as otherwise directed by Nissan North America.
^
The ECM can be permanently damaged if the reprogramming procedure is not followed exactly.
^
Do not disturb (don't touch) the vehicle, CONSULT-II, or the DLC-II cable while ECM reprogramming is in progress.
^
If the ECM is damaged, it must be replaced.
Service Procedure
NOTE:
When ECM reprogramming is required to repair a vehicle, a Technical Service Bulletin will be issued.
ECM reprogramming involves two general steps:
^
Download (transfer) data from ASIST into CONSULT-II.
^
Download new data from CONSULT-II into the vehicle (Reprogram ECM).
Before beginning the reprogramming procedure, use CONSULT-II and the Diagnostic Card (red/white one) to retrieve any stored DTC(s). Additional
repairs may be necessary if there are DTC(s) not associated with a Reprogramming bulletin. Refer to the appropriate TSB or Service Manual.
