For Secondary Fuel Injector #1, #2, #3, #4

Digital Meter (+) → R (injector W/R) lead

Digital Meter (–) → Battery (–) terminal

For Secondary Fuel Injectors


Power Source Voltage Standard: Battery Voltage for 3 seconds, and then 0 V

If the reading stays on battery voltage and never shows 0 V, check the fuel pump relay (see Relay Circuit Inspection in the Electrical System chapter).

If the fuel pump relay is normal, check the ECU for its ground and power supply (see ECU Power Supply Inspection).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).

If there is still no battery voltage, check the fuel pump relay (see Relay Circuit Inspection in the Electrical System chapter).

If the fuel pump relay is normal, check the power source wiring (see wiring diagram in this section).

Special Tool - Hand Tester: 57001-1394

If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).

If the reading is in specification, check the output voltage (see Fuel Injector Output Voltage Inspection).

For Primary Fuel Injectors
Remove the air cleaner housing (see Air Cleaner Housing Removal). Disconnect the injector connector and connect the harness adapter [A] between these connectors as shown in the figure. ...

Precautions
1) No need of topping-up No topping-up is necessary in this battery until it ends its life under normal use. Forcibly prying off the seal cap to add water is very dangerous. Never do that. 2) Refreshing charge. Give refresh charge for 5 to 10 hours with charge current shown in the text (see ...

Camshaft Runout Inspection
Remove the camshafts (see Camshaft Removal). Set the camshaft in a camshaft alignment jig or on V blocks. Measure the runout with a dial gauge at the specified place as shown in the figure. If the runout exceeds the service limit, replace the camshaft. Camshaft Runout Standard: TIR ...

Headlight Bulb Replacement
Turn the cover [A] counterclockwise, and remove it. Disconnect the headlight connector [A]. Open the clamp [B], and remove the bulb. NOTICE When handling the quartz-halogen bulb, never touch the glass portion with bare hands. Always use a clean cloth. Oil contamination from hand ...
