ON-BOARD DIAGNOSTIC
SIMULATION TEST
Shift Solenoid Valve A, B, and C
1. Connect the NGS to the DLC.
2. Turn the ignition switch to ON.
Note
• For information on how to operate the NGS,
refer to the instruction manual that comes with
the NGS.
3. Select the “SIMULATION TEST’ on the NGS.
(See F1 -35 ON-BOARD DIAGNOSTIC TEST,
Simulation Test Procedure.)
4. Perform the simulation test.
• If no operation sound is heard from solenoid
valve, inspect solenoid valve.
Pressure Control Solenoid Valve
1. Connect the NGS to the DLC.
2. Perform mechanical system test preparation.
(See K2-21 MECHANICAL SYSTEM TEST,
Mechanical System Test Preparation.)
Warning
• Removing the square-head plug when the
ATF is hot can be dangerous. Hot ATF can
come out of the opening and badly burn
you. Before removing the square-head
plug, allow the ATF to cool.
3. Connect the SSTs (49 H019 002,49 0378 400B) tol
the line pressure inspection port. Then replace the
gauge of the SST (49 0378 400B) with (49 B019
901A).
4. Start the engine.
5. Select the “SIMULATION TEST’ on the NGS.
(See F1-35 ON-BOARD DIAGNOSTIC TEST,
Simulation Test Procedure.)
Caution
• After the simulation test, be sure to idle for
one minute or more in N position.
Otherwise the transaxle could be damaged.
Note
• For information on how to operate the NGS,
refer to the instruction manual that comes with
the NGS.
6. Perform the simulation test and verify that the line
pressure changes as shown in the chart below.
• If the line pressure does not increase or
decrease corresponding to the linear value,
inspect the pressure control solenoid.
