FI SYSTEM DIAGNOSIS 4-63Step 21) Connect the TO sensor coupler and ECM coupler.2) Insert the needle pointed probes to the lead wire coupler.3) Turn the ignition switch to ON.4) Measure the voltage at the wire side coupler between B andB/Br wires. TO sensor voltage (Normal): 0.4 – 1.4 V(+ B – - B/Br)2VAlso, measure the voltage when leaning the motorcycle.5) Dismount the TO sensor from its bracket and measure thevoltage when it is leaned 65° and more, left and right, fromthe horizontal level. TO sensor voltage (Leaning): 3.7 – 4.4 V(+ B – - B/Br) 09900-25008: Multi-circuit tester set09900-25009: Needle pointed probe set Tester knob indication: Voltage ()265˚VIs the voltage OK?2YESNO• R, B or B/Br wire open or shorted to ground, orpoor A, L or S connection• If wire and connection are OK, intermittent troubleor faulty ECM.• Recheck each terminal and wire harness foropen circuit and poor connection.• Replace the ECM with a known good one, andinspect it again.• Loose or poor contacts on the ECM coupler• Open or short circuit• Replace the TO sensor with a new one.ECM couplers (Harness side)6) After repairing the trouble, clear the DTC using SDS tool.(4-26)“C24” (P0351), “C25” (P0352), “C26” (P0353) or “C27” (P0354) IGNITIONSYSTEM MALFUNCTION* Refer to the IGNITION SYSTEM for details.
