Check for initial voltage at this time.
Connection: Black/white(+) · Green (-)
Standard: Battery voltage
If the initial voltage cannot be measured, check the
power supply circuit.
Check f or continuity of the Blue/black, Yellow/white,
Red/blue and Red/yellow wires between the ECM
connector and each direct ignition coil connector.
If no defects are found in wire harness, replace the
direct ignition coil with a new one and recheck ini-
tial valve.
If the inti a I voltage is measured, replaced direct igni-
tion coil is faulty.
If the initial voltage cannot be measured, replace the
ECM with a new one and recheck.
IGNITION PULSE GENERATOR PEAK
VOLTAGE
• Check all system connections before inspection.
If the system is disconnected, incorrect peak volt-
age might be measured.
• Check cylinder compression and check that the
spark plugs are installed correctly.
• Use recomm ended digital mu ltimeter or com-
mercia lly available digital multimeter with an
impedance of 10 MntDCV minimum.
• The display value differs depending upon the
internal impedance of the multimeter.
• If the peak voltage tester (U.S.A. only) is used,
follow the manufactu rer's instruction.
Connect t he peak voltage tester or peak voltage
adaptor to the digital multi meter.
TOOLS:
Peak voltage tester (U.S.A o nly) or
Peak voltage adaptor 07HGJ-0020100
(not available in U.S.A.) with comm ercially available
digital multimeter (impedance 10 MO/DCV mini-
m um)
