STARTER RELAY SWITCH OPERATION INSPECTION

6-6

Remove the rear fender cover (page 2-8).

Turn the ignition switch ON and engine stop switch "O~.

Shift the transmission into neutral or apply front brake .

Push the starter switch.

The relay coil is normal if the starter relay switch [1] clicks. If you don't hear the switch "CLICK", inspect the relay switch using the procedure below.

CIRCUIT INSPECTION Ground Line :

Disconnect the starter relay switch 2P (Green) , -----------------, connector (page 6-7).

Check for continuity between the wire harness side 2P (Green) connector [1J terminal and ground.

Connection : Green - Ground

There should be continuity at all limes.

Turn the ignition switch ON and engine stop sWitch yt.

Shift the transmission into neutral or apply front brake.

Measure the voltage between the Wife harness side 2P (Green) connector 111 terminal and ground .

Connection : Yellow/red (+) - Ground H There should be battery vol lage only when the starter switch IS pushed.

CONTINUITY INSPECTION Remove the starter relay switch [1J (page 6-7).

Connect the fully charged 12 V [2) battery to the starter relay switch 2P (Green) connector [3J terminals .

Connection: Battery (+) terminal - Yellow/red Battery (-) terminal - Light green/red

There should be continuity between the cable terminals while the battery is connected, and no continuity when the battery is disconnected.

REMOVALIINSTALLA TION Disconneclthe battery negative H cable (page 22-5).

Disconnect the starter relay switch 2P (Green) connector [1].

Remove the terminal nuts [2). spring washers [3). battery positive (+) cable [4) and starter motor cable [5].

Remove the starter relay switch [6] from the rear fender with the shock rubber (71.

Remove the starter relay switch from the shock rubber.

Installation is in the reverse order of removal.

INSPECTION Remove the PCMfECM from the ECM stay (page 4-36).

Remove the screws [1] and relay box lid [2J.

Remove the starter inhibitor relay [1) and starter relay switch diode [2).

Connect an ohmmeter to the starter Inhibitor relay [1] ,-----,-,--------------, terminals as shown and check for continuity. {1 J There should be continuity. \

Connect a 12 V battery to Ihe relay terminals as shown. There should be no continuity only when the 12 V battery is connected.

Check for continuity between the terminals of the diode ~===============~ III III When Ihere is continuity, a small resistance value will register. If there is continuity in one direction. the diode is normal.

FUEL SYSTEM

SERVICE INFORMATION GENERAL

This section covers service of the mechanical system of the PGM-FI system and the fuel supply system. For electrical system service of the PGM-FI system, see PGM-Ft System section (page 4-2). Before disconnecting the fuel feed hose, relieve pressure from the system (page 7-5). Bending or twisting the control cable will impair smooth operation and could cause the cable to stick or bend, resulting in loss of vehicle control. Work in a well ventilated area. Smoking or allowing flames or sparks in the work area or where gasoline is stored can cause a fire or explosion . Do nOI snap the throttle valve from full open to full close after the throttle cable has been removed. It may cause incorrect idle operation. Seal the cylinder head intake port with tape or a clean cloth to keep dirt and debris from entering the intake port after the throttle body has been removed. Do not damage the throttle body. It may cause incorrect throttle valve operation. Prevent dirt and debris from entering the throttle bore, IACV, sensor hole and fuel feed hose. Clean them using compressed air. The throttle body is factory pre-set. Do not disassemble in a way other than shown in this manual. Do not loosen or tighten the white painted screws and nut of the throttle body. loosening or tightening them can cause throttle body malfunction. Tighten the yellow painted screws of the throttle body to the specified torque. When disassembling the fuel system parts, note the location of the O-rings. Replace them with new ones upon reassembly. When servicing the fuel feed hose , be careful nolto bend or kink it.
