Technical information

BOSCH
Types:
• EDC15V, EDC15-C5, and EDC16
NOTE: While there have been other Bosch modules, the EDC15V is not flash
reprogrammable.
TRANSMISSION CONTROL MODULES (TCM)
Transmission controllers are usually flashed on the vehicle (since 1996).
Technicians may set the pinion factor on "NEW" modules either before or after flash
reprogramming. Suggestions follow.
After flash reprogramming and before returning the vehicle to the customer, always
perform a “QuickLearn” to the TCM.
EATX
Types:
• EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A
NOTE: Table shows which TCM was installed "as-built". Often TCMs are superseded
by parts and or a service bulletin.
Abort Recovery Specifics:
• 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement
EATX4A part numbers 56041814AD and 56028227AH currently display a P/N read
failed error after the flash is completed during P/N verification. This DOES NOT
mean the flash failed. Check for the part number using DRBIII® in standalone mode.
This exists only for the service replacement modules listed above. Flash
reprogramming for OE modules flash and read the part number correctly. Follow
DRBIII® prompts carefully.
NGC
Types:
• NGC 1, NGC2, NGC 3
NOTE: The NGC 1 and NGC 3 have the EATX/XCORE and Engine modules
combined. NGC 2 does not. Vehicles with automatic transmissions using
NGC 2 will use an EATX 4A.
Abort Recovery Specifics:
• Follow DRBIII® prompts carefully.
• 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some
instances the CAB controller may need to be disconnected when attempting to flash
the NGC controller. (This should only be performed if an error occurs at the very
beginning of the TCM flash portion.)
SIEMENS
Types:
• EGS52
