ELECTRICAL SYSTEM 10-19
Correct
• Faulty ECM
• Faulty wire harness
• Improper ignition
coupler connection
Measure the battery voltage between
input lead wires (O/W and B/W) at the
ECM with the ignition switch in the
“ON” position.
Inspect the spark plug (-s).
( : 2-7)
Measure the ignition coil primary peak
voltage. ( : 10-20)
NOTE: The ignition coil peak voltage
inspection methotd is applicable only
with the multi circuit tester and the peak
volt adaptor.
Inspect the ignition coil/plug cap (-s).
( : 10-21)
Correct
Measure the CKP sensor peak voltage
and its resistance. ( : 10-21 to 10-22)
NOTE: The CKP sensor peak voltage
inspection is applicable only with the
multi circuit tester and peak volt adaptor.
