POWERTRAIN VERIFICATION TEST VER - 6 APPLICABILITY
1. NOTE: If the PCM has been replaced and the correct VIN and mileage have not
been programmed, a DTC will be set in the ABS Module, Airbag Module and the
SKIM.
2. NOTE: If the vehicle is equipped with a Sentry Key Immobilizer System, Secret
Key data must be updated. Refer to the Service Information for the PCM, SKIM and
the Transponder (ignition key) for programming information.
3. Inspect the vehicle to ensure that all engine components are properly installed and
connected. Reassemble and reconnect components as necessary.
4. The LDP Monitor Test Mode has been added to the DRBIII to verify repairs to the LDP
System. A DRB software program was written which causes the PCM to run the LDP Monitor
as part of this test. Test failures will be indicated through a stored DTC.
5. LDP Monitor Test Mode is a useful way to run a total system performance test. Use this test
to verify any type of LDP system repair.
6. Software program makes temporary changes to operating mode of PCM. For this reason, it
is critical that test not be interrupted. PCM's left in this mode as result of interrupted test will
illuminate the MIL for 8-10 mi of driving with no DTC's stored.
7. Erasing DTC's will not change this condition.
8. If a vehicle is found to be stuck in the mode described above, the LDP Dealer Test should be
re-run in its entirety so that the software program in the DRBIII can restore the PCM
operating mode.
9. Note similarity to LDP Monitor screen found under OBDII Monitors. Failure modes are
fewer in this System Test than OBDII LDP Monitor. System Test only stores Small Leak DTC
to indicate problem with system. No other type of failure mode indication given.
10. System Test failure may have been, for example, due to a large leak, but the PCM will set
the Small Leak DTC to indicate failures that occurred as part of the system test.
11. Connect the DRB to the data link connector. Engine running, turn off all accessories.
12. Note: While test is being performed, PCM must see RPM, minimum MAP, No Vehicle speed
and minimum Throttle Position sensor (At idle, in park.) With DRBIII in System Tests, perform
the LDP Monitor Test and follow the instructions on the screen.
13. If the LDP Monitor Test failed and a Small Leak DTC has set, the repair is not complete.
Check for any related Technical Service Bulletins and return to Symptom List.
14. If any other trouble code has set, return to Symptom List and follow the path specified for
that trouble code. If the LDP Monitor Test passed, the repair was successful and testing is now
complete.
Are any DTCs present?All
Ye s®Repair is complete.
No®Repair is not complete, refer to appropriate symptom.

3.3.7 DTC DESCRIPTIONS
Name of code:P1792(12) - Battery was Discon-
nected (Informational code Only)
When monitored:Whenever the key is in the
Run/Start position.
Set condition:This code is set whenever the
Transmission Control Module (TCM) is discon-
nected from battery power (B+) or ground. It will
also be set during the DRBIIItBattery Disconnect
procedure.
Theory of operation:A battery backed RAM
(Random Access Memory) is used to maintain some
learned values. When the battery B(+) is discon-
nected, the memory is lost. When the B(+) is re-
stored, this memory loss is detected by the TCM.
The code is set and the learned values are initial-
ized to known constants or previously learned val-
ues from EEPROM (Electronic Erasable Program-
mable Read Only Memory). This results in the
initialization of some parameters.
Transmission Effects:Loss of trouble code data.
Immediate limp-in mode if power is lost while
operating the vehicle. Normal operation is resumed
if the power is restored during the same key start.
Possible causes:
> Battery voltage removed from TCM
> TCM disconnected
> Dead Battery
> Low battery voltage during cranking
> Battery Disconnect by DRBIIItor MDS
> Bad TCM ground circuit.
Name of code:P1767(14) - Relay Output Always
On
When monitored:Ignition key is turned from off
position to run position and/or ignition key is
turned from crank position to run position.
Set condition:This code is set if the Transmission
Control Module (TCM) senses greater than 3 voltsat the Trans Relay Output (switched battery) ter-
minal of the TCM prior to the TCM energizing the
relay.
Theory of operation:The transmission control
relay is used to supply power to the solenoid pack
when the transmission is in normal operating
mode. When the relay is off, no power is supplied to
the solenoid pack and the transmission is in limp-in
mode. The relay output is fed back to the TCM
through pins 16 and 17. It is referred to as the
Trans Relay Output circuit or switched battery.
Transmission Effects:The MIL will illuminate
and the transmission system defaults to Logical
limp-in mode. Logical Limp-in mode results in the
same modes of operation as Relay Open Limp-in.
Since the relay is stuck9on9, the TCM can not open
the relay, and the TCM shifts to 2nd gear.
Possible causes:
> Relay failure (welded contacts)
> Short to battery in 12-volt supply and/or Trans-
mission Control Relay Output circuit(s)
> Short to voltage
> TCM connector problems
> TCM
Name of code:P1768(15) - Relay Output Always
Off
When monitored:Continuously
Set condition:This code is set when less than 3
volts are present at the Trans Relay Output
(switched battery) terminals at the Transmission
Control Module (TCM) when the TCM is energizing
the relay.
Theory of operation:The transmission control
relay is used to supply power to the solenoid pack
when the transmission is in normal operating
mode. When the relay is off, no power is supplied to
the solenoid pack and the transmission is in limp-in
mode. The relay output is fed back to the TCM
through pins 16 and 17. It is referred to as the
Trans Relay Output circuit or a switched battery.

GENERAL INFORMATION

Page 4110 of 4284

After a controller reset (ignition key turned to the
run position or after cranking engine), the control-
ler energizes the relay. Prior to this the TCM
verifies that the contacts are open by checking for
no voltage at the switched battery terminals. After
the relay is energized, the TCM monitors the ter-
minals to verify that the voltage is greater than 3
volts.
Transmission Effects:The MIL illuminates and
the transmission system defaults to Relay Open
limp-in mode.
Possible causes:
> Relay failure (intermittent relay function caused
by oxidized or contaminated relay contacts)
> Short to ground or open circuit in the Transmis-
sion Control Relay circuit(s)
> TCM connector problem
> TCM
Name of code:P0725(18) - Engine Speed Sensor
Circuit
When monitored:Whenever the engine is run-
ning.
Set condition:This code is set when the engine
speed sensed by the Transmission Control Module
(TCM) is less than 390 RPM or greater than 8000
RPM for more that 2.0 seconds.
Theory of operation:The TCM uses either a
EATX RPM signal (simulated Crank Sensor signal)
or the TCM uses the Crank Postion Sensor signal to
calculate engine RPM depending on the engine
application. The signal supplied by the PCM and
uses a dedicated circuit is called the EATX RPM
Signal circuit. The Crank Position Sensor signal is
a spliced circuit from the engine Crank Position
Sensor. If the TCM interprets this signal to be out of
range when the engine is running (as reported by
the PCM over the bus) the code is set.
Transmission Effects:The MIL illuminates and
the transmission system defaults to Relay Open
limp-in mode.
Possible causes:
> Open or short in EATX RPM Signal circuit. (3.5L)
> Open or short in Crank Position Sensor Signal
circuit. (3.3L/3.8L)
> Open or short in Crank Position Sensor ground
circuit. (3.3L/3.8L)
> TCM and/or PCM connector problems
> TCM
> PCMName of code:P0716(19) - Bus Communication
with Engine Module
When monitored:Continuously with key on.
Set condition:If no PCI bus messages are received
from the Powertrain Control Module (PCM) for 10
seconds.
Theory of operation:The TCM communicates
with the PCM using the PCI bus. It relies on certain
information to function properly. The TCM contin-
uously monitors the PCI bus to check for messages
broadcast from the PCM.
Transmission Effects:Delayed 3-4 shifts. No
EMCC and early 3-4 shifts for a few minutes after
engine is started.
Possible causes:
> Open or shorted PCI bus circuit
> TCM
> PCM
Name of code:P1765(20) - Switched Battery
When monitored:Ignition key is turned from off
position to run position and/or ignition key is
turned from crank position to run position.
Set condition:This code is set if the Transmission
Control Module (TCM) senses voltage on any of the
pressure switch inputs prior to the TCM energizing
the relay.
Theory of operation:The transmission control
relay is used to supply power to the solenoid pack
when the transmission is in normal operating
mode. When the relay is off, no power is supplied to
the solenoid pack and the transmission is in a
limp-in mode. The relay output is fed back to the
TCM through pins 16 and 17. It is referred to as the
Trans Relay Output circuit or a switched battery.
Immediately after a controller reset (ignition key
turned to the run position or after cranking engine),
the TCM verifies that the relay contacts are open by
checking for no voltage at the switched battery
terminals. After this is verified, the voltage at the
Solenoid Pack pressure switches is checked. There
should be no voltage on the pressure switches at
this time. The TCM will then activate the relay.
Transmission Effects:The MIL illuminates and
the transmission system defaults to Relay Open
limp-in mode.
Possible causes:
> Short to battery on one or more pressure switch
sense circuits
> TCM connector problems
> TCM
