Meter (–) → Battery (–) terminal

Input Voltage at ECU	Battery Voltage
Standard:

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.
