FI SYSTEM DIAGNOSIS 4-73 “C31” (P0705) GP SWITCH CIRCUIT MALFUNCTION DETECTED CONDITION POSSIBLE CAUSE No Gear Position switch voltage • Gear Position switch circuit open or short Switch voltage is not within the following range. • Gear Position switch malfunction Switch voltage > 0.6 V • ECM malfunction ECM Side-stand relay To engine stop switch Ignition GP switch switch BI GP P P N E1 B/W 6 1 Neutral indicator 5 light B/W 2 4 3 Side-stand switch INSPECTION 1 Step 1 E 1) Turn the ignition switch OFF. 2) Lift and support the fuel tank. (5-3) L 3) Check the GP switch coupler for loose or poor contacts. If OK, then measure the GP switch voltage. P SAM 4) Support the motorcycle with a jack. 1 5) Fold the side-stand to up position. V 6) Make sure the engine stop switch is in the “RUN” position. 7) Insert the needle pointed probe to the lead wire coupler. 8) Turn the ignition switch ON. 9) Measure the voltage at the wire side coupler between Pink wire and B/W wire, when shifting the gearshift lever from 1st to Top. GP switch voltage:0.6 V and more (+ Pink – - B/W) 09900-25008: Multi-circuit tester set 09900-25009: Needle pointed probe set Tester knob indication: Voltage ()
