Do not disconnect the ECU connector.
Connect a digital meter to the ECU connector, using the needle adapter.
- Special Tool - Needle Adapter Set: 57001-1457
Measure the power source voltage with the engine stopped, and with the connector joined.
Turn the ignition switch ON.
Injector power source voltage at ECU:
(other than Europe models [A])
- Connections: Meter (+) → BR/W (terminal 12)
- Meter (-) → Battery (-) Terminal

(Europe Models [B])
- Connections: Meter (+) → BR/W (terminal 16)
- Meter (-) → Battery (-) Terminal

- Service Limit: Battery Voltage (12.8 V or more)
★ If the meter doesn't read as specified, check the following.
- Main Fuse 30 A (see Fuse inspection in the Electrical System chapter)
- Fuel Pump Relay (see Relay circuit inspection in the Electrical System chapter)
- Power Source Wiring (see wiring diagram below)
To check the W/R leads between the injector connector and the fuel pump relay, remove the fuel tank (see Fuel tank removal) and the right side cover (see Right side cover removal in the Frame chapter).
★ If the power source voltage is normal, check the output voltage of the injectors.
Output voltage inspection
Turn the ignition switch OFF.
Remove the ECU (see ECU removal). Do not disconnect the ECU connector.
Connect a digital voltmeter to the connector, using the needle adapter set.

Injector output voltage at ECU:
(Other than Europe Models [A])
- Connections for Injector #1
- Meter (+) → BL/R lead (terminal 34)
- Meter (-) → Battery (-) Terminal
- Connections for Injector #2
- Meter (+) → BL/G lead (terminal 33)
- Meter (-) → Battery (-) Terminal

(Europe Models [B])
- Connections for Injector #1
- Meter (+) → BL/R lead (terminal 42)
- Meter (-) → Battery (-) Terminal
- Connections for Injector #2
- Meter (+) → BL/G lead (terminal 41)
- Meter (-) → Battery (-) Terminal

Turn the ignition switch ON.
Start the engine.
- Standard: Battery Voltage (12.8 V or more)
Turn the ignition switch OFF.
★ If the output voltage is normal, perform "Injector Signal Test".
★ If the output voltage is out of the standard, turn the ignition switch OFF, remove the fuel tank, and check the injector wiring for continuity.
Injector wiring inspection:
(Other than Europe Models)
ECU Connector | Injector Connectors | |
Terminal 12 | → | Injector #1 Terminal (W/R) |
Terminal 12 | → | Injector #2 Terminal (W/R) |
Terminal 34 | → | Injector #1 Terminal (BL/R) |
Terminal 33 | → | Injector #2 Terminal (BL/G) |
(Europe Models)
ECU Connector | Injector Connectors | |
Terminal 16 | → | Injector #1 Terminal (W/R) |
Terminal 16 | → | Injector #2 Terminal (W/R) |
Terminal 42 | → | Injector #1 Terminal (BL/R) |
Terminal 41 | → | Injector #2 Terminal (BL/G) |
★ If the wiring is good, inspect the resistance of the injectors (see Injector resistance inspection).
Remove the needle adapter.
Apply silicone sealant to the seals of the ECU connector for waterproofing.
