AUTOMATIC TRANSMISSION (AW30-40LE) 7A–23
INTERMITTENT CONDITIONS
If the Tech2 displays a code as intermittent, or if after a
test drive a code does not reappear, the problem is most
likely a faulty electrical connection or loose wiring.
Terminals should always be the prime suspect.
Intermittent rarely occur in sophisticated electronic
components such as the Transmission Control Module
(TCM).
When an intermittent problem is encountered, check
suspect circuits for:
• Poor terminal to wire connection.
• Terminals not fully seated in the connector body
(backed out).
• Improperly formed or damaged terminals.
• 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.
• Pinched or damaged wires.
• Electro-Magnetic Interference (EMI)
HINT: Check that all wires are properly routed away
from spark plug wires, distributor wires, coil,
and generator. Also check for improperly
installed electrical options, such as lights, 2-
way radios, etc.
Use the F2: SNAPSHOT mode of the Tech2 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 "trigger" on the
suspect code (or codes) or, if you notice the repor ted
symptom during test drive, trigger the snapshot
manually.
After the snapshot has been triggered, command the
Tech2 to play back the flow of data recorded from each
of the various sensors. Signs of an intermittent fault in a
sensor circuit are a sudden unexplainable jump in data
values out of the normal range.

7A–34 AUTOMATIC TRANSMISSION (AW30-40LE)
DTC P0717 (FLASHING CODE 14) INPUT REVOLUTION SENSOR FAILURE (NC0)
D07RY00020
Circuit description:
Input revolution information is provided to TCM by the
input revolution sensor. This sensor is located in the
transmission case.
The input revolution sensor is an electromagnetic pulse
pickup type that generates a speed signal according to
the revolution of the transmission OD direct clutch drum.
As a result, the sensor sends a sine wave signal (AC) to
the TCM, which conver ts this sine wave signal (pulse
voltage) to a RPM signal.
Fail-safe control:
The TCM controls fail-safe by detecting input revolution
sensor failure.
Failure detection:
• When not even 1 pulse is input in the input revolution
sensor during the time 4 pulses are input in the
output revolution sensor.
• When the failure criteria is continuously 1000 times
from the time ignition is turned ON until it is turned
OFF.
Prohibits failure detection when at least one among the
following conditions is satisfied.
• When D, 2 and L range signal is not fixed.
• When output revolution is less than 775 rpm.
• When the failure detection timer T1 (*1) is less than
25 seconds.
• Solenoid S1, S2, and selector position switch is on
failure detection or decision.
• At 4th gear.
• When passed less than 10 seconds after shift
command output.
*1: Failure detection inhibit timer T1
Timer star ts when D, 2 or L range are detected (fixation
signal).
Contents of control:
At failure detection• Lock-up control inhibit
• Up hill and down hill control inhibit
At failure decision
Executes following items in addition to above control
items at failure detection.
• Blinks "CHECK TRANS" lamp
• Stores the failure information in failure-memory
Conditions of turning "CHECK TRANS" off:
At D, 2 or L range and not shifting, turns "CHECK
TRANS" lamp off when judged 0km/h by output
revolution sensor after more than 1 pulse input in the
input revolution sensor and finished vehicle speed
calculation during the time 4 pulse are input in the output
revolution sensor.
Reversion conditions from fail-safe:
Recovers at the same time as the conditions of turning
“CHECK TRANS” lamp off are satisfied.
Test description:
The following numbers correspond to circled numbers on
the diagnostic char t.
(1) When the engine is running, a revolution signal is
input from the input revolution sensor to the TCM.
(2) At this test, the continuity of circuit wiring and the
input revolution sensor is checked.
(3) At this test, the continuity of the input revolution
sensor is checked.
Diagnostic aids:
An intermittent may be caused by a poor connection,
rubbed through wire insulation or a wire broken inside
the insulation. Inspect related harness connector for
backed out terminals, improper mating, broken locks,
improperly formed or damaged terminals, poor terminal
to wire connection and damaged harness.
