FI SYSTEM DIAGNOSIS 4-91 “C49” (P1656) PAIR CONTROL SOLENOID VALVE CIRCUIT MALFUNCTION DETECTED CONDITION POSSIBLE CAUSE PAIR control solenoid valve voltage is not input to • PAIR control solenoid valve circuit open or short ECM. • PAIR control solenoid valve malfunction • ECM malfunction ECM Engine stop Side-stand Ignition switch relay switch RAIR W/G O/W To side-stand switch PAIR control solenoid valve INSPECTION 1 Step 1 E 1)Turn the ignition switch OFF. 2)Remove the air cleaner box. (5-13) L 3)Check the PAIR control solenoid valve coupler for loose or poor contacts. P If OK, then measure the PAIR control solenoid valve resis- tance. AM 4)Remove the PAIR control solenoid valve. (11-6) 1 S 5)Measure the resistance between terminals. PAIR valve resistance: 18 – 22 Ω at 20 – 30 °C (68 – 86 °F) (Terminal – Terminal) 09900-25008: Multi-circuit tester set Tester knob indication: Resistance (Ω) Is the resistance OK? YES Go to Step 2. NO Replace the PAIR valve with a new one. 6)After repairing the trouble, clear the DTC using SDS tool. (4-27)
