FLASH PROGRAMMING CONTINUED
N OT E
If you are flash programming ECM as directed by troubleshooting, proceed to next step. If
replacing an ECM, proceed to Copy Configuration To ECM in this work package.
11. Start and run engine until operating temperature is reached and verify proper operation of all components
(TM 5-2410-240-10). Check for active diagnostic codes by selecting Active Diagnostic Codes from the
Diagnostics menu.

INITIALIZING ECM
00017
N OT E
Two key start ON/OFF cycles are required for correct initialization of new ECM.
1. Turn battery disconnect switch to ON position (TM 5-2410-240-10).
2. Turn engine start switch to ON position (TM 5-2410-240-10).
3. Wait one minute to allow ECM to initialize.
4. Turn engine start switch to OFF position (TM 5-2410-240-10) and wait ten seconds.
5. Turn engine start switch to ON position (TM 5-2410-240-10).
Electronic Technician (ET)will indicate whether ECM has been programmed or not.
If ECM is not programmed, program ECM using WinFla h software contained within Electronic Technician
s
(ET). Proceed to FLASH PROGRAMMING in this work package.
If ECM is programmed, Electronic Te hnician (ET) will allow access to ECM to load configuration data.

ECM UNABLE TO COMMUNICATE
00017
N OT E
This procedure is for non-communicating ECMs.
The first steps will verify that the data linkcircuit between the diagnostic connector and the
ECM is not causing a communication problem.
1. Turn engine start switch to OFF position (TM 5-2410-240-10).
2. Turn battery disconnect switch to OFF position (TM 5-2410-240-10).
3. Check ECM and Ignition Power and Ground (WP 0013).
4. Disconnect J1 connector from ECM.
5. At each harness, connect a jumper wire between data link (+) (circuit 893-GN) and data link (-)
(circuit 892-BR).
