MFI SYSTEM CHECK PROCEDURE (4WD
A/T)
HINT:
• Perform all voltage measurements with the connec–
tors connected.
• Verify that the battery voltage is 11 V or more when
the ignition switch is in ”ON” position.
Using a voltmeter with high impedance (10 k/V
minimum), measure the voltage at each terminal of
the wiring connector.
