DTC P1717 RAM Error
Circuit Description
A normal function of the Transmission Control Module
(TCM) programming is to perform an internal check
that verifies the integrity of the RAM memory
allocations.
The DTC P1717 sets when the Random Access Memory
(RAM) is not operating correctly when checked on
initialization. An area of RAM has failed a read/ write
test.
Conditions for Setting the DTC
An area of RAM has failed a read/ write test.
Immediately after the above condition occurs.
Action Taken When the DTC Sets
Adopt Limp Home Mode (LHM)
Outputs are disabled.
DIAGNOSTIC TROUBLE CODE (DTC) P1717
RAM ERROR
The transmission adopts the third gear LHM
strategy of operation, independent of the vehicle
speed. The operation of TCM under this condition
is difficult to predict. Its operation may be erratic.
Conditions for Clearing the DTC
The DTC will clear if the malfunction is not present
after cycling the ignition.
A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 °C) and
without a fault.
History DTCs can be cleared by using a scan tool.
Diagnostic Aids
When DTC P1717 sets, the replacement of TCM is
recommended.
1Perform a Transmission Control Module (TCM)
Diagnostic System Check.
Is the check performed?
1. Install the scan tool.
2. Turn the ignition ON, with the engine OFF.
Does the scan tool display P1717?
1. Turn the ignition OFF.
2. Replace the TCM.
Is the action complete?
1. Using the scan tool, clear the DTCs.
2. Road test the vehicle within the conditions for
setting this DTC as specified in the text.
Does the scan tool indicate that this diagnostic has
run and passed?
Check if any DTCs are set.
Are there any DTCs displayed or previously recorded
at Step 2 that have not been diagnosed?

DTC P1718 ROM Error
Circuit Description
A normal function of the Transmission Control Module
(TCM) programming is to perform an internal check
that verifies the integrity of the ROM memory
allocations. This function is called a checksum.
The DTC P1718 sets when the Read Only Memory
(ROM), program memory, is corrupted when checked
on initialization. The calculated checksum disagrees
with the stored checksum.
Conditions for Setting the DTC
TCM has been powered ON for greater than 7 sec-
onds.
The calculated checksum disagrees with the stored
checksum. The malfunction is triggered immediately
after this condition exists.

DTC P1720 EEPROM Error
System Description
The Electrically Erasable Programmable Read-Only
Memory (EEPROM) is a permanent memory chip that
is physically soldered within the Transmission Control
Module (TCM). The EEPROM contains the calibration
information required for transmission and transmission
diagnostics operation. When the EEPROM malfunc-
tions, DTC P1720 will set. The EEPROM memory is
corrupted and the calculated checksum disagrees with
the stored checksum or an EEPROM communication
failure has occurred when checked on initialization.
Conditions for Setting the DTC
The calculated checksum disagrees with the stored
checksum or an EEPROM communication failure has
occurred when checked on initialization.
Immediately after the above condition occurs.
DIAGNOSTIC TROUBLE CODE (DTC) P1720
EEPROM ERROR
Action Taken When the DTC Sets
If CAN is detected, OBD N32D VIN is selected. Or
If CAN is not detected, P29 STi VIN is selected.
Default values are used which are typical of
calibrated values.
Shift quality may be degraded.
Conditions for Clearing the DTC
The DTC will only clear if the malfunction is not pres-
ent after cycling the ignition.
A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 °C) and
without a fault.
History DTCs can be cleared by using a scan tool.
Diagnostic Aids
When DTC 1720 is set, it is likely the TCM will need
replacing.

nostic System Check.
