SYSTEM CHECK PROCEDURE (2WD)
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 (l0 kΩ/V
minimum), measure the voltage at each terminal of
the wiring connectors.
