Ignition Coil Input Voltage at Ignition Coil
Connections for Ignition Coil #1, #4
Meter (+) → R/Y lead
Meter (–) → Battery (–) terminal
Connections for Ignition Coil #2, #3
Meter (+) → R/Y lead
Meter (–) → Battery (–) terminal
Input Voltage at ECU
Standard: Battery Voltage
If the reading is out of the standard, check the wiring (see
next wiring diagram).
If the reading is good, the input voltage is normal. Crank
the engine, and check the peak voltage of the ignition
coils (see Electrical System chapter) in order to check the
primary coils.
