TECH2 CONNECTION
The Tech2 scan tool is used to electrically diagnose the
automatic transmission system and to check the system. The
Tech2 enhances the diagnosis efficiency though all the
troubleshooting can be done without the Tech2.
The Tech2 is a portable, compact, and light tester. When it is
connected to the diagnosis connector of the vehicle, you can
perform a variety of diagnoses and tests by communicating
with the Transmission Control Module (TCM) of the vehicle.
1. Configuration of Tech2
1. Tech2 scan tool kit (No. 7000086), Tech2 scan tool (No.
7000057) and DLC cable (No. 3000095)
2. SAE16/19 adapter (No. 3000098) (1), RS232 loop back
connector (No. 3000112) (2), and PCMCIA card (No.
3000117) (3)
2. Tech2 Connection
•Observe the Tech2 User Guide.
1. Check the ignition is OFF.
2. Inser t the ISUZU 2000 system PCMCIA card (1) into the
Te c h 2 ( 4 ) .
3. Connect the SAE16/19 adapter (2) to the DLC cable (3).
4. Connect the DLC cable (3) to the Tech2 (4).
5. Connect the SAE16/19 adapter (2) to the diagnosis
connector of the vehicle.
6. Turn the ignition of the vehicle ON and press the "PWR"
key of the Tech2.
•Check the display of the Tech2.
NOTE:
Be sure to check that the power is not supplied to the
Tech2 when attaching or removing the PCMCIA card.

7A–38 AUTOMATIC TRANSMISSION (AW30-40LE)
DTC P0727 (FLASHING CODE 13) ENGINE REVOLUTION SIGNAL FAILURE (NE)
D07RY00019Circuit description:
Engine revolution (rpm) signals are sent from Engine
Control Module (ECM) to the Transmission Control
Module (TCM).
The engine speed sensor is an electromagnetic pulse
pickup type that generates signals when the flywheel
gear revolves (2 pulses at a single revolution of the
flywheel gear).
The TCM converts these sine wave signals into engine
revolution (RPM) signals.
Fail-safe control:
The TCM controls fail-safe by detecting engine revolution
sensor failure.
Failure detection:
• When input revolution is more than 2000 rpm
• When not even 1 pulse is input in the engine
revolution signal during 5 seconds
• Detection inhibit condition: At 4th gear
Contents of control:
At failure detection
• Up hill and down hill control inhibit
• Oil temperature sensor failure detection inhibit
• Blinks "CHECK TRANS" lamp
• Stores the failure information in failure memory.
At failure decision
Same as failure detection
Conditions of turning "CHECK TRANS" lamp off:
Turns "CHECK TRANS" lamp off when judged 0km/h by
speed meter sensor after the engine revolution signal
pulses are input 250 pulses normally.
(however, uses 0 km/h judgment by back-up vehicle
speed at output revolution failure)
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) Engine revolution signals are input from the ECM into
the TCM.
(2) When the engine idling, voltage fluctuates with (AC
intermittent) range of less than 1.4V
9 16V.
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.
