5A-78 AUTOMATIC TRANSMISSION
DIAGNOSTIC TROUBLE CODE (DTC) P1709
Circuit Description
The battery voltage monitoring input is connected to
the positive side of the battery. This signal is taken
from the main supply to the TCM.
If the battery voltage is greater than 16.5 V, DTC P1709
will be set and the transmission will adopt limp home
mode and all solenoids are turned OFF.
Conditions for Setting the DTC
•
The indicated supply voltage is greater than 16.5 V.
•
The malfunction triggers immediately after this
condi-tion exists.
Action Taken When the DTC Sets
•
All solenoids are turned OFF while the high battery
voltage condition is detected.
•
The transmission goes into Limp Home Mode (LHM).
Conditions for Clearing the DTC
•
The DTC will clear when the malfunction has not
occurred for 30 seconds.
•
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.
TCM SUPPLY VOLTAGE HIGH
Diagnostic Aids
•
The voltage measured by the TCM corresponding
to the battery supply voltage has been outside the
range of the maximum operating voltage of 16.5 V.
•
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
wires 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.
4. Checks if the generator is malfunctioning under
load conditions.
5. Check connection of other connectors.
