Ignition Coil #2: Ignition Coil for Rear Cylinder (Service Code 52)
Ignition coil removal/installation
Caution! Never drop the ignition coils, especially on a hard surface. Such a shock to the ignition coil can damage it.
Refer to the Ignition coil removal in the Electrical System chapter.
Input voltage inspection
Note. OBe sure the battery is fully charged.
Turn the ignition switch OFF.
Remove the ECU (see ECU removal). Do not disconnect the ECU connector.
Connect a digital voltmeter as shown, using two needle adapters.
Special Tool - Needle Adapter Set: 57001-1457
Measure the input voltage to each primary winding of the ignition coils with the engine stopped, and with the connectors joined.
Turn the ignition switch ON.
Ignition coil input voltage at ECU:
(Other than Europe Models [A])
- Connections for Ignition Coil #1
- Meter (+) → BK lead (terminal 35)
- Meter (-) → Battery (—) Terminal
- Connections for Ignition Coil #2
- Meter (+) → BK/G lead (terminal 44)
- Meter (-) → Battery (—) Terminal
(Europe Models [B])
- Connections for Ignition Coil #1
- Meter (+) → BK lead (terminal 43)
- Meter (-) → Battery (—) Terminal
- Connections for Ignition Coil #2
- Meter (+) → BK/G lead (terminal 52)
- Meter (-) → Battery (—) Terminal

Standard: Battery Voltage (12.8 V or more)
★ If the reading is out of the standard, check the ECU for its ground and power supply (see ECU power supply inspection).
★ If the reading is good remove the fuel tank and check the wiring between the ECU and the primary lead terminals at the ignition coils.
★ If the wiring is good, crank the engine, and check the peak voltage of the ignition coils (see Ignition coil primary peak voltage inspection in the Electrical System chapter) in order to check the primary coils.
