5A-96 AUTOMATIC TRANSMISSION
DIAGNOSTIC TROUBLE CODE (DTC) P1719
Circuit Description
The Controller Area Network (CAN) connects various
control modules by using a twisted pair of wires, to
share common information. This results in a reduction
of sensors and wiring. TCM obtains the actual engine
speed and throttle position, vehicle speed and
accelerator position etc. from ECM via CAN without
any additional sensors.
The DTC P1719 sets when the information required by
TCM is not available on the CAN. One or more CAN
messages used by the TCM is timed out, i.e. not re-
freshed for 1 second.
Conditions for Setting the DTC
•
One or more CAN messages used by the TCM are
timed out, i.e. not refreshed for 1 second.
Action Taken When the DTC Sets
•
TCM uses default values for all CAN dependent sig-
nals.
Conditions for Clearing the DTC
•
The DTC will clear when the malfunction has not
occurred for 30 seconds.
CAN BUS ERROR
•
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 and ECM connectors. 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
