5A-102 AUTOMATIC TRANSMISSION
DIAGNOSTIC TROUBLE CODE (DTC) P1722
Circuit 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 program and
the calibration information required for the transmission
and transmission diagnostics operation.
The DTC P1722 sets when TCM is unable to determine
the vehicle type from EEPROM or CAN. CAN vehicle
type information is in error or unavailable in time.
By definition, there must by on EEPROM fault (P1720)
or an EEPROM vehicle code error (P1714) to cause the
TCM to try and determine the vehicle code by other
means.
The DTC P1722 is a reflection of the significance of
the problem caused by the other error.
Conditions for Setting the DTC
•
EEPROM information is in error or unreliable.
•
Vehicle type information on the CAN is not present
or in error.
•
The above condition exists for 1 second after power
up.
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.
•
Shift quality may be degraded.
VEHICLE TYPE DETERMINATION ERROR
Conditions for Clearing the DTC
•
The DTC will clear when the malfunction has not
occurred after ignition cycle.
•
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
•
Inspect the wiring for poor electrical connections
at the TCM connector. Look for possible bent,
backed out, deformed or damaged terminals. Check
for weak terminal tension as well. Also check for
chafed wires that could short to bare metal or other
wiring. Inspect for broken wire inside the insulation.
•
If diagnosing for a possible intermittent short or
open condition, move or massage the wiring harness
while observing test equipment for a change
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
3. If there are any other DTCs like P1714 or P1720,
troubleshoot those prior to P1722.
