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.

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.

DIAGNOSTIC TROUBLE CODE (DTC) P1718

ROM ERROR

Action Taken When the DTC Sets

•

Adopt Limp Home Mode (LHM)

•

The transmission adopts the third gear LHM strategy
of operation, independent of the vehicle speed. The
operation of TCM under this condition cannot be
predicted. 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 P1718 sets, the replacement of TCM is
recommended.

5A-94  AUTOMATIC TRANSMISSION

SSANGYONG  MY2002

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.

DIAGNOSTIC TROUBLE CODE (DTC) P1719

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

The number(s) below refer to the step number(s) on
the Diagnostic Table.

6. Check for a poor connection at the ECM and TCM

connectors.
