DIAGNOSTIC TROUBLE CODE (DTC) P1715
Circuit Description
The VPS is used to regulate the clutch and band pres-
sures during a shift. The TCM compares TP voltage,
engine rpm and other inputs to determine the pressure
appropriate for a given shift. The TCM will regulate
pressure by applying a varying amperage to the
Variable Pressure Solenoid (VPS) valve. The applied
amperage can vary from 0 to 1.275 amps. The TCM
then monitors the amperage at the return line.
This VPS offsets calibrate the accuracy between actual
and expected VPS current.
The DTC P1715 sets when the VPS offset value stored
in EEPROM is out of range when checked on initializa-
tion. The VPS offset is greater than 120 mA from nomi-
nal.
Step
Perform a Transmission Control Module (TCM)
1
Diagnostic System Check.
Is the check performed?
1. Install the scan tool.
2. Turn the ignition ON, with the engine OFF.
3. Record and then clear DTCs.
2
4. Operate the vehicle within the conditions for
setting this DTC as specified in the text.
Does the scan tool display P1715?
1. Turn the ignition OFF.
3
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.
4
Does the scan tool indicate that this diagnostic has
run and passed?
Check if any DTCs are set.
5
Are there any DTCs displayed or previously recorded
at Step 2 that have not been diagnosed?

DTC P1715 VPS Offset Error
Action
AUTOMATIC TRANSMISSION 5A-91
Conditions for Setting the DTC
•
DTC P1720 is not set.
•
The VPS offset is greater than 120 mA from nominal.
The malfunction is triggered immediately after this
condition exists.
Action Taken When the DTC Sets
•
Default values are used which are typical of the
calibrated values.
•
Shift quality may be degraded.
Conditions for Clearing the DTC
•
This DTC can only be cleared by recalibrating the
VPS and then cycling power to the TCM. This is a
factory procedure.
•
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.
