Chart 16: Possible Causes Of
Transmission Fluid Leaks
Before attempting to correct an oil leak, the actual source
of the leak must be determined. In many cases, the
source of the leak may be difficult to determine due to
ªwind flowº around the engine and transmission.
The suspected area should be wiped clean before in-
specting for the source of the leak.Oil leaks around the engine and transmission are gener-
ally carried toward the rear of the vehicle by the air
stream. In determining the source of an oil leak, the fol-
lowing two checks should be made:
1. With the engine running, check for external line
pressure leaks.
2. With the engine off, check for oil leaks due to the
raised oil level caused by drainback of converter oil
into the transmission.

Intermittent Conditions
If the Tech 2 displays a diagnostic trouble code as
intermittent, or if after a test drive a DTC does not
reappear though the detection conditions for this DTC are
present, the problem is most likely a faulty electrical
connection or loose wiring. Terminals and grounds should
always be the prime suspect. Intermittents rarely occur
inside sophisticated electronic components such as the
PCM.
Use the DTC information to understand which wires and
sensors are involved.
When an intermittent problem is encountered, check
suspect circuits for:
1. Poor terminal to wire connection.
2. Terminals not fully seated in the connector body
(backed out).
3. Improperly formed or damaged terminals.
4. Loose, dirty, or corroded ground connections:
HINT: Any time you have an intermittent in more than
one circuit, check whether the circuits share a
common ground connection.5. Pinched or damaged wires.
6. Electro±Magnetic Interference (EMI):
HINT: Check that all wires are properly routed away
from coil, and generator. Also check for improperly
installed electrical options, such as lights, 2±way
radios, etc.
Use the F2: SNAPSHOT mode of the Tech 2 to help
isolate the cause of an intermittent fault. The snapshot
mode will record information before and after the problem
occurs. Set the snapshot to ªtriggerº on the suspect DTC.
If you notice the reported symptom during the test drive,
trigger the snapshot manually.
After the snapshot has been triggered, command the
Tech 2 to play back the flow of data recorded from each of
the various sensors. Signs of an intermittent fault in a
sensor circuit are sudden unexplainable jump in data
values out of the normal range.

TRANSMISSION CONTROL SYSTEM (4L30±E)7A1±79
DTC P1860 TCC PWM Solenoid Electrical
D07R200011
Circuit Description
The PCM allows current to flow through the solenoid coil
according to the duty cycle (percentage of ªonº and ªoffº
time). This current flow through the solenoid coil creates
a magnetic field that magnetizes the solid core. The
magnetized core attracts the check ball to seat against
spring pressure. This blocks the exhaust for the TCC
signal fluid and allows 2±3 drive fluid to feed to TCC signal
circuit.The TCC signal fluid pressure acts on the TCC
regulator valve to regulate line pressure and to apply fluid
pressure to the torque converter clutch shift control valve.
When the TCC shift valve is in the apply position,
regulated apply fluid pressure is directed through the TCC
valve to apply the torque converter clutch. The TCC
PWM solenoid is used in conjunction with the TCC PWM
solenoid to regulate fluid to the torque converter. The
TCC PWM solenoid is attached to the valve body within
the transmission.
This DTC detects a continuous open or short to ground or
ignition in the TCC circuit or the TCC PWM solenoid. This
is a type ªBº DTC.
Conditions For Setting The DTC

Battery voltage is between 10 and 16 volts.

No shift solenoid A DTCs P0751 or P0752 or P0753.

No shift solenoid B DTCs P0756 or P0757 or P0758.

Ignition is ªonº, Engine ªrunº.

The PCM commands the solenoid ªonº and the
voltage remains low (zero volts).

The PCM commands the solenoid ªoffº and the
voltage remains high (B+).

All conditions met for 0.875 ~ 1.25 seconds.
Action Taken When The DTC Sets

Inhibit TCC engagement.
For lamp illuminate refer to
DTC type definition (type
B).
Conditions For Clearing The MIL/DTC

The PCM will turn off the MIL and CHECK TRANS
Lamp after three consecutive ignition cycles without a
failure reported.

The DTC can be cleared from the PCM history by
using a scan tool.

The DTC will be cleared from history when the vehicle
has achieved 40 warmup cycles without a failure
reported.

The PCM will cancel the DTC default actions when
the fault no longer exists and the ignition is cycled ªoffº
long enough to power down the PCM.
Diagnostic Aids

Inspect the wiring for poor electrical connections at
the PCM and at the transmission connector. Look for
possible bent, backed out, deformed or damaged
terminals. Check for weak terminal tension as well.
Also check for a chafed wire that could short to bare
metal or other wiring. Inspect for a broken wire inside
the insulation.

When diagnosing for a possible intermittent short or
open condition, move the wiring harness while
observing test equipment for a change.
Test Description
The numbers below refer to the step numbers on the
diagnostic chart
:
3. This test checks for voltage to the solenoid.
4. This test checks the ability of the PCM and wiring to
control the ignition circuit.
9. This test checks the resistance of the TCC solenoid
and the internal wiring harness.

Service Precaution
CAUTION: When fasteners are removed, always
reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use
the correct part number fastener for that application.
If the correct part number fastener is not available, a
fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those
requiring thread locking compound will be called
out. The correct torque value must be used when
installing fasteners that require it. if the above
conditions are not followed, parts or system damage
could result.
WARNING: WHEN PERFORMING SERVICE ON OR
AROUND SRS COMPONENTS OR SRS WIRING,
FOLLOW THE PROCEDURES LISTED BELOW TO
TEMPORARILY DISABLE THE SRS. FAILURE TO
FOLLOW PROCEDURES COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY OR OTHERWISE UNNEEDED SRS REPAIRS.
The SDM in Driver±Passenger SRS can maintain
sufficient voltage to cause a deployment for up to 15
seconds after the ignition switch is turned ªOFF,º the
battery is disconnected, or the fuse powering the SDM is
removed.
Many of the service procedures require removal of the
ªSRS±1º fuse, and disconnection of the air bag assembly
from the deployment loop to avoid an accidental
deployment. If the air bag assembly is disconnected from
the deployment loop as noted in the ªDisabling the SRSº
procedure that follows, service can begin immediately
without waiting for the 15 second time period to expire.
Disabling The SRS
Removal
Turn the ignition switch to ªOFFº and turn the steering
wheel so that the vehicle's wheels are pointing straight
ahead.
1. Remove SRS fuse SRS±1, from left dash side lower
fuse block or disconnect battery.
2. Disconnect yellow 2±pin connector at the base of
steering column.
3. Remove glove box assembly; Refer to ªPassenger
Air Bag Assembly Replacementº in this section.
4. Disconnect passenger air bag assembly yellow 2±pin
connector behind the glove box assembly.
CAUTION: With the ªSRS±2º fuse removed and
ignition switch ªON,º the ªAIR BAGº warning lamp
will be ªON.º This is normal operation and does not
indicate an SRS malfunction.
Enabling The SRS
Installation
Turn ignition switch to ªLOCKº and remove key.
1. Connect yellow 2±pin connector passenger air bag
assembly.
2. Install glove box assembly, Refer to ªPassenger Air
Bag Assembly Replacementº in this section.3. Connect yellow 2±pin connector at the base of the
steering column.
4. Install ªAIR BAGº fuse SRS±1 to left dash side lower
fuse block or connect battery.
Turn ignition switch to ªONº and verify that the ªAIR BAGº
warning lamp flashes seven times and then turns ªOFFº If
it does not operate as described, perform the ªSRS
Diagnostic System Checkº in section 9J±2.
Handling / Installation / Diagnosis
1. Air bag assembly should not be subjected to
temperatures above 65
C (150
F).
2. Air bag assembly, and SDM should not be used if they
have been dropped from a height of 100 centimeters
(3.28 feet) or more.
3. When a SDM is replaced, it must be oriented with the
arrow on the SDM pointing toward the front of the
vehicle. It is very important for the SDM to be located
flat on the mounting surface, parallel to the vehicle
datum line. It is important that the SDM mounting
surface is free of any dirt or other foreign material.
4. Do not apply power to the SRS unless all components
are connected or a diagnostic chart requests it, as this
will set a diagnostic trouble code.
5. The ªSRS Diagnostic System Checkº must be the
starting point of any SRS diagnostics. The ªSRS
Diagnostic System Checkº will verify proper ªAIR
BAGº warning lamp operation and will lead you to the
correct chart to diagnose any SRS malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements.
Inspections Required After An Accident
CAUTION: C e r t a i n S R S c o mponents must be
replaced after a frontal crash involving air bag
deployment.
In all types of accidents regardless of ªAir Bagº
deployment, visually inspect all of the following
components and replace as required:
Ð Driver air bag assembly
Ð Passenger air bag assembly
Ð Steering wheel
Ð SRS coil assembly
Ð Steering column
Ð Knee bolster and instrument panel mounting
