INSPECTION PROCEDURE
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
METER:
OK: Needle indication is normal.
2 READ VALUE OF INTELLIGENT TESTER (ENGINE SPEED SIGNAL)
METER:
OK: Engine speed displayed on the tester is almost the same as the actual engine speed.
REPLACE COMBINATION METER ASSEMBLY
3 READ VALUE OF INTELLIGENT TESTER (ENGINE SPEED SIGNAL)
ENGINE:
4 CHECK HARNESS AND CONNECTOR (COMBINATION METER - ECM)
Standard resistance
5 INSPECT COMBINATION METER ASSEMBLY
OK: The waveform is displayed as shown in the illustration
REPLACE ECM
Pressure Control Solenoid "A" Performance (Shift Solenoid
Valve SL1)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to
detect the actual gear position (1st, 2nd, 3rd, 4th
or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory
to detect mechanical
problems of the shift solenoid valves, valve b ...
