Flash Programming
This is a method of programming or updating the flash file in an engine's Electronic Control Module (ECM). Use
this procedure if original ECM flash files are missing or not available. To update configuration files, Caterpillar Electronic Technician (ET) is used to flash program a file into the memory of the
engine's ECM. If you do not have the flash file, it must be obtained from your Caterpillar dealer.
MALFUNCTION
Personality Module Mismatch. ECM has an incorrect or outdated Flash File.
CORRECTIVE ACTION
STEP 1.
On EMCP, set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 2.
Connect the Cat ET to connector CDC-P7
STEP 3.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
On EMCP set ENGINE CONTROL switch to COOL DOWN/STOP.
STEP 4.
Establish communication between Cat ET and the engine's ECM.
STEP 5.

STEP 6.
